An anterior surface of the haptic is configured to contact an inner capsule wall surface at the anterior leaflet. A posterior surface of the haptic includes a ridge configured to capture at least one edge of the intraocular lens so as to secure the intraocular pseudophakic contact lens to the intraocular lens. Different portions of the optic provide different amounts of magnification, such that a first portion of the optic provides a first amount of magnification and a second portion of the optic provides a second amount of magnification.

Description

Technical Field

[0001] The present disclosure relates generally to implantable optical devices and, more particularly, to an intraocular pseudophakic contact lens having a mechanism for fixation via the anterior leaflet of the capsule wall and a related system and method. Background Art

[0002] In a normal eye, light enters through the cornea and passes through the pupil, and the natural lens focuses the light onto the eye's retina. However, due to cataracts or other problems, it may be necessary to replace the eye's natural lens with an intraocular lens (IOL). The term "pseudophakic" is used to describe an eye in which the natural lens has been replaced with an intraocular lens.

[0003] Before placing an intraocular lens (IOL) in a patient's eye, a doctor or other personnel typically selects an IOL designed to provide the desired refractive correction for the patient's eye. For example, an IOL may have an optical lens designed to correct myopia (nearsightedness), hyperopia (hyperopia), astigmatism, or other refractive errors that naturally occur in the patient's eye. However, it is often the case that the IOL selected for the patient's eye does not fully correct (and may even cause) a certain form of refractive error in the patient's eye. This refractive error is called "residual" refractive error.

[0004] There are various conventional options for correcting residual refractive error, all of which have their drawbacks. For example, one intraocular lens in a patient's eye can be replaced with a different intraocular lens, but this typically carries a high risk of surgical complications. Ablative surgery on the patient's cornea (such as LASIK) can be performed to correct residual refractive error, but this can be associated with a high level of unwanted side effects, particularly in elderly patients. An additional intraocular lens (often called a "piggyback" IOL) can be inserted in front of the existing intraocular lens, but this is typically an invasive procedure with low predictability of the final refractive outcome. Alternatively, an intracorneal lens (ICL) can be inserted into the patient's cornea, but this is typically even more invasive and highly risky. Generally speaking, these procedures are often unpredictable and carry a high degree of surgical risk. Furthermore, the equipment used in these procedures can make it difficult to remove and "reverse" any residual refractive error, leading to a higher risk of induced visual aberrations for the patient. Summary of the Invention

[0005] The present disclosure provides an intraocular pseudophakic contact lens having a mechanism for fixation through the anterior leaflet of the capsule wall, and related systems and methods.

[0006] In a first embodiment, a device includes an intraocular pseudophakic contact lens having an optic and a haptic extending radially from the optic. The haptic is configured to be inserted beneath an anterior leaflet of a capsule wall in an eye so as to capture and confine the haptic beneath the anterior leaflet and secure the intraocular pseudophakic contact lens against an intraocular lens in the eye. An anterior surface of the haptic is configured to contact an inner capsule wall surface at the anterior leaflet. A posterior surface of the haptic includes a ridge configured to capture at least one edge of the intraocular lens so as to secure the intraocular pseudophakic contact lens to the intraocular lens.

[0007] In a second embodiment, a system includes a system comprising an intraocular lens having a first optic and a first haptic configured to be implanted in a capsular bag of an eye. The system also includes an intraocular pseudophakic contact lens having a second optic and a second haptic extending radially from the second optic. The second haptic is configured to be inserted beneath an anterior leaflet of a capsule wall in the eye so as to capture and confine the second haptic beneath the anterior leaflet and secure the intraocular pseudophakic contact lens against the intraocular lens in the eye. The anterior surface of the second haptic is configured to contact an inner capsule wall surface at the anterior leaflet. The posterior surface of the second haptic includes a ridge configured to capture at least one edge of the intraocular lens so as to secure the intraocular pseudophakic contact lens to the intraocular lens.

[0008] In a third embodiment, a device comprises a device comprising an intraocular pseudophakic contact lens having an optic and at least three haptics extending radially from the optic. The haptics are configured to be inserted beneath an anterior leaflet of a capsule wall in an eye so as to capture and confine the haptics beneath the anterior leaflet and secure the intraocular pseudophakic contact lens against an intraocular lens in the eye. The anterior surface of the haptics is configured to contact an inner capsule wall surface at the anterior leaflet. The posterior surface of the haptics comprises a ridge and a lip projecting inwardly from the ridge, wherein the ridge and lip are configured to capture at least one edge of the intraocular lens so as to secure the intraocular pseudophakic contact lens to the intraocular lens. Each haptic comprises an inner portion and an outer portion, wherein the inner portion of each haptic is positioned between the optic and the outer portion of the haptic. The inner portion of each haptic projects outwardly and rearwardly from the optic. For each haptic, a ridge is defined where the greater thickness of the outer portion of the haptic meets the lesser thickness of the inner portion of the haptic.

[0027] Discussed below Figures 1 to 38 The various embodiments used to describe the principles of the present invention in this patent document are intended to be illustrative only and should not be construed in any way to limit the scope of the present invention. Those skilled in the art will appreciate that the principles of the present invention can be implemented in any type of suitably arranged device or system.

[0028] The present disclosure provides various intraocular pseudophakic contact lenses (IOPCLs) that can be used in conjunction with an intraocular lens (IOL). An intraocular pseudophakic contact lens generally refers to a contact lens-type device that can be implanted within a patient's eye and placed on the anterior surface of the intraocular lens in the patient's eye. In some embodiments, the intraocular pseudophakic contact lens substantially corrects the residual refractive error that exists after implantation of the intraocular lens, such as after phacoemulsification (cataract) surgery. In other embodiments, the intraocular pseudophakic contact lens provides some other form of vision correction when placed over the intraocular lens in the patient's eye. Additionally, the intraocular pseudophakic contact lens includes haptics or other mechanisms that allow the intraocular pseudophakic contact lens to be constrained / captured by the anterior leaflet of the capsule wall in the patient's eye. In some cases, the haptics or other mechanisms can actually attach to the anterior leaflet of the capsule wall, such as by fibrosis during the healing process, to help secure the intraocular pseudophakic contact lens in place.

[0029] Unlike conventional methods, intraocular pseudophakic contact lenses can be implanted with minimal surgical risk. Furthermore, intraocular pseudophakic contact lenses allow patients to see immediately following implantation. Furthermore, if a different lens is needed, such as to correct residual refractive error or provide some other form of vision correction, the intraocular pseudophakic contact lens can be easily replaced, or even removed if necessary. Furthermore, with currently available technology (such as intraoperative wavefront aberration measurement), the refractive outcome can be measured during the actual surgery in which the intraocular pseudophakic contact lens is being implanted, helping to immediately confirm that the desired refractive goal has been achieved.

[0030] Figures 1 to 3 A first exemplary intraocular pseudophakic contact lens 100 according to the present disclosure is shown. In particular, Figure 1shows an oblique view of an intraocular pseudophakic contact lens 100, Figure 2 A top view of an intraocular pseudophakic contact lens 100 is shown, and Figure 3 A side view of an intraocular pseudophakic contact lens 100 is shown.

[0031] like Figures 1 to 3 , an intraocular pseudophakic contact lens 100 includes an optic 102. Optic 102 represents the portion of the intraocular pseudophakic contact lens 100 that alters light passing through the intraocular pseudophakic contact lens 100. Light passing through optic 102 then travels through an associated intraocular lens before reaching the retina of the patient's eye.

[0032] The optical lens 102 can be formed from any suitable material, such as silicone or acrylic. The optical lens 102 can also be formed in any suitable manner, such as by using a mold or lathe cutting manufacturing process. Different lenses 102 can be designed and manufactured to provide a wide range of diopters, and each optical lens 102 can be designed to correct any suitable refractive error or provide other suitable vision correction. Exemplary types of refractive errors that can be corrected include myopia, hyperopia, and astigmatism.

[0033] In this example, the optical lens 102 has a convex top surface and a concave bottom surface. However, the optical lens 102 can have any other suitable shape, which can depend (at least in part) on the type of refractive error being corrected or other vision correction being performed. As specific examples, the optical lens 102 can be convex, concave, spherical, aspherical, toric, monofocal, or multifocal. The specific lens platform used as the optical lens 102 in the intraocular pseudophakic contact lens 100 can be selected to provide the desired refractive correction or other vision correction in the patient's eye. The optical lens 102 can also include various other features as needed or desired, such as when the optical lens 102 is weighted (e.g., at its bottom) so that the optical lens 102 itself is oriented in a desired orientation on the intraocular lens (e.g., for a toric platform), or when the optical lens 102 is tinted, photochromic, or includes an ultraviolet (UV) absorber.

[0034] A plurality of haptics 104a-104b extend from multiple sides of the optical lens 102. The haptics 104a-104b are sized and shaped so that they extend a short distance from the optical lens 102 and fit under the anterior leaflet of the capsule wall in the patient's eye after implantation. Each haptic 104a-104b can be made of any suitable material and formed in any suitable manner. For example, each haptic 104a-104b can be formed of the same material as the optical lens 102. It should be noted that although two haptics 104a-104b are shown here, the intraocular pseudophakic contact lens 100 can include any number of haptics, including a single haptic. Furthermore, it should be noted that although the haptics 104a-104b are angled downward, the haptics 104a-104b can have any other suitable arrangement.

[0035] In this example, the haptics 104a-104b are separated from the optical lens 102 by protrusions or extensions 106 that protrude from the sides of the optical lens 102. These extensions 106 represent a portion of the intraocular pseudophakic contact lens 100 into which the ends of the haptics 104a-104b can be embedded. Each extension 106 can be made of any suitable material and formed in any suitable manner. For example, each extension 106 can represent a portion of the material forming the optical lens 102 and, therefore, an extension of the optical lens 102 itself. However, this need not be the case. For example, the optical lens 102 can be placed within a retaining ring that is integral with or attached to the extensions 106, or the extensions 106 can be secured to the optical lens 102 itself using an adhesive or other suitable connection mechanism.

[0036] It should be noted that although two extensions 106 are shown here, the intraocular pseudophakic contact lens 100 may include any number of extensions, including a single extension. Furthermore, it should be noted that the presence of extensions 106 is not required, and the haptics 104a-104b may be directly integrated with the optical lens 102. In those embodiments, the haptics 104a-104b may represent part of the material forming the optical lens 102, but this need not be the case. For example, the optical lens 102 may be placed within a retaining ring that is integral with or attached to the haptics 104a-104b, or the haptics 104a-104b may be secured to the optical lens 102 itself using an adhesive or other suitable connection mechanism.

[0037] Each of the haptics 104a-104b includes a textured surface 108, which in this example is formed using various holes formed partially or completely through the haptics 104a-104b. The textured surface 108 allows the haptics 104a-104b to be captured and confined by the anterior leaflet of the capsule wall in the patient's pseudophakic eye. In some cases, the textured surface 108 allows the haptics 104a-104b to actually physically bond to the anterior leaflet of the capsule wall in the patient's eye during the healing process, such as by fibrosis. The haptics 104a-104b help to secure the intraocular pseudophakic contact lens 100 in place on the intraocular lens. It should be noted that the number and size of the holes in the textured surface 108 are for illustration only, and the haptics 104a-104b can include a different number and size of holes. For example, the haptics 104a-104b may include a large number of very small holes or other structures to form a texture that promotes confinement, capture, or attachment to the anterior leaflet of the capsule wall.

[0038] The anterior leaflet of the capsule wall in a patient's eye is often formed during a capsulotomy, a procedure in which the natural lens is removed and replaced with an intraocular lens. The anterior leaflet refers to the outer portion of the anterior side of the capsular bag that remains after an opening (called a capsulotomy) is formed in the capsular bag to allow for removal of the natural lens. In some cases, this can occur long before the intraocular pseudophakic contact lens 100 is implanted. Following the capsulotomy, the anterior leaflet of the capsule wall often shrinks and undergoes fibrosis during the healing process.

[0039] When the intraocular lens 100 is inserted into the patient's eye, the intraocular lens 100 can be positioned so that the haptics 104a-104b extend beneath the anterior leaflet in the patient's eye. This allows the haptics 104a-104b to be captured and restrained by the anterior leaflet. The haptics 104a-104b can also physically attach to the anterior leaflet over time, such as through "refibrosis" of the anterior leaflet. This refibrosis of tissue will bind to and cover some or all of the haptics 104a-104b, further securing the intraocular lens 100 in place. However, it should be noted that the intraocular lens 100 can also be implanted during the same procedure in which an intraocular lens is implanted. In this case, the intraocular lens 100 can be secured by the haptics 104a-104b and, potentially, during the fibrosis (rather than refibrosis) within the patient's eye.

[0040] Figure 4 and Figure 5 A second exemplary intraocular pseudophakic contact lens 400 according to the present disclosure is shown. In particular, Figure 4 An oblique view of an intraocular pseudophakic contact lens 400 is shown, and Figure 5 A side view of an intraocular pseudophakic contact lens 400 is shown.

[0041] like Figure 4 and Figure 5 , intraocular pseudophakic contact lens 400 has various components that are the same or similar to those forming intraocular pseudophakic contact lens 100. For example, intraocular pseudophakic contact lens 400 includes an optic 402, a plurality of haptics 404a-404b, and optionally, a plurality of extensions 406. Haptics 404a-404b include a textured surface 408.

[0042] The intraocular pseudophakic contact lens 400 also includes one or more pins 410. Each pin 410 projects downwardly from the extension 406 or from the inner end of the haptics 404a-404b. The pins 410 can be used to pierce the anterior surface of the intraocular lens or rest on the anterior surface of the intraocular lens. In addition to the capture / restriction of the haptics 404a-404b by the anterior leaflet, the pins 410 can also help further hold the intraocular pseudophakic contact lens 400 in place and resist sliding of the intraocular pseudophakic contact lens 400. In some cases, the pins 410 can be used to prevent movement of the intraocular pseudophakic contact lens 400 during the period immediately after implantation and before the haptics 404a-404b of the intraocular pseudophakic contact lens 400 have become bonded to the anterior leaflet of the capsule wall in the patient's eye (such as through fibrosis).

[0043] Each pin 410 can be made of any suitable material and formed in any suitable manner. It should be noted that although two pins 410 are shown here, the intraocular pseudophakic contact lens 400 can include any number of pins, including a single pin. Furthermore, it should be noted that although the pins 410 are shown here as having sharp ends, this need not be the case. For example, the pins 410 can have rounded or blunted surfaces to help the pins 410 rest on (without piercing) the anterior surface of the intraocular lens. Additionally, although the pins 410 are shown here as extending through or embedded within the extension 406, the pins 410 can be located in any other suitable location. For example, the pins 410 can be moved to the outer ends of the haptics 404a-404b, or additional pins 410 can be placed at the outer ends of the haptics 404a-404b.

[0044] As described above, the intraocular pseudophakic contact lens 400 can be implanted during the same procedure in which the intraocular lens is implanted, or during a subsequent procedure after the intraocular lens has already been implanted in the patient's eye. The anterior leaflet of the capsule wall of the patient's eye can be used to capture and confine the haptics 404a-404b of the intraocular pseudophakic contact lens 400 beneath the anterior leaflet, and optionally, fibrosis or refibrosis can occur to attach the haptics 404a-404b to the patient's eye. Pins 410 can be used to help hold the intraocular pseudophakic contact lens 400 in place.

[0045] Figures 6 to 8 A third exemplary intraocular pseudophakic contact lens 600 according to the present disclosure is shown. In particular, Figure 6 An oblique view of an intraocular pseudophakic contact lens 600 is shown, Figure 7 A top view of an intraocular pseudophakic contact lens 600 is shown, and Figure 8 A side view of an intraocular pseudophakic contact lens 600 is shown.

[0046] like Figures 6 to 8 As shown in FIG, an intraocular pseudophakic contact lens 600 includes an optical lens 602, which can be the same as or similar to the optical lenses 202 and 402 described above. The intraocular pseudophakic contact lens 600 also includes a plurality of haptics 604a-604b and, optionally, a plurality of extensions 606. The haptics 604a-604b are formed here by a ring of material (such as metal or plastic). In this example, the ends of the haptics 604a-604b are embedded in the extensions 606, although the extensions 606 can be omitted, and the haptics 604a-604b can be coupled to the optical lens 602 or to a retaining ring in which the optical lens 602 is placed. It should be noted that although the haptics 604a-604b are angled downward, the haptics 604a-604b can have any other suitable arrangement. Each of the haptics 604a-604b can include a textured surface that facilitates restriction, capture, or attachment to the anterior leaflet of the capsule wall.

[0047] The intraocular pseudophakic contact lens 600 can be implanted during the same procedure in which the intraocular lens is implanted or during a subsequent procedure after the intraocular lens has been implanted in the patient's eye. The anterior leaflet of the capsule wall of the patient's eye can be used to capture and confine the haptics 604a-604b of the intraocular pseudophakic contact lens 600 beneath the anterior leaflet, and optionally, fibrosis or refibrosis can occur to attach the haptics 604a-604b to the patient's eye.

[0048] Figure 9 and Figure 10 A fourth exemplary intraocular pseudophakic contact lens 900 according to the present disclosure is shown. In particular, Figure 9 An oblique view of an intraocular pseudophakic contact lens 900 is shown, and Figure 10 A side view of an intraocular pseudophakic contact lens 900 is shown.

[0049] like Figure 9 and Figure 10 , an intraocular pseudophakic contact lens 900 has various components that are the same or similar to those forming the intraocular pseudophakic contact lens 600. For example, the intraocular pseudophakic contact lens 900 includes an optical lens 902, a plurality of haptics 904a-904b, and optionally a plurality of extensions 906. The haptics 904a-904b form small loops that are sized and shaped so that they extend a short distance from the optical lens 902 and fit under the anterior leaflet of the capsule wall in the patient's eye after implantation. Each of the haptics 904a-904b may include a textured surface that facilitates restriction, capture, or attachment to the anterior leaflet of the capsule wall.

[0050] The intraocular pseudophakic contact lens 900 also includes one or more pins 908. Each pin 908 projects downwardly from the extension 906 or from the inner end of the haptics 904a-904b. The pins 908 can be used to pierce the anterior surface of the intraocular lens or rest on the anterior surface of the intraocular lens. In addition to the capture / restriction of the haptics 904a-904b by the anterior leaflet, the pins 908 can also help further hold the intraocular pseudophakic contact lens 900 in place and resist sliding of the intraocular pseudophakic contact lens 900. In some cases, the pins 908 can be used to prevent movement of the intraocular pseudophakic contact lens 900 during the period immediately after implantation and before the haptics 904a-904b of the intraocular pseudophakic contact lens 900 have become bonded to the anterior leaflet of the capsule wall in the patient's eye (such as through fibrosis).

[0051] Each pin 908 can be made of any suitable material and formed in any suitable manner. It should be noted that although two pins 908 are shown here, the intraocular pseudophakic contact lens 900 can include any number of pins, including a single pin. Furthermore, it should be noted that although the pins 908 are shown here as having sharp ends, this need not be the case. For example, the pins 908 can have rounded or blunted surfaces to help the pins 908 rest on (and not pierce) the anterior surface of the intraocular lens. Additionally, although the pins 908 are shown here as extending through or embedded within the extension 906, the pins 908 can be located in any other suitable location. For example, the pins 908 can be moved to the outer ends of the haptics 904a-904b, or additional pins 908 can be placed at the outer ends of the haptics 904a-904b.

[0052] The intraocular pseudophakic contact lens 900 can be implanted during the same procedure in which the intraocular lens is implanted, or during a subsequent procedure after the intraocular lens has already been implanted in the patient's eye. The anterior leaflet of the capsule wall of the patient's eye can be used to capture and confine the haptics 904a-904b of the intraocular pseudophakic contact lens 900 beneath the anterior leaflet, and optionally, fibrosis or refibrosis can occur to attach the haptics 904a-904b to the patient's eye. Pins 908 can be used to help hold the intraocular pseudophakic contact lens 900 in place.

[0053] Figure 11 and Figure 12 A fifth exemplary intraocular pseudophakic contact lens 1100 according to the present disclosure is shown. In particular, Figure 11 An oblique view of an intraocular pseudophakic contact lens 1100 is shown, and Figure 12 A side view of an intraocular pseudophakic contact lens 1100 is shown.

[0054] like Figure 11 and Figure 12 , an intraocular pseudophakic contact lens 1100 has various components that are the same or similar to those forming the intraocular pseudophakic contact lens 900. For example, the intraocular pseudophakic contact lens 1100 includes an optical lens 1102, a plurality of haptics 1104a-1104b, and optionally, a plurality of extensions 1106. The haptics 1104a-1104b form small loops that are sized and shaped so that they extend a short distance from the optical lens 1102 and fit under the anterior leaflet of the capsule wall in the patient's eye after implantation. Each of the haptics 1104a-1104b may include a textured surface that facilitates restriction, capture, or attachment to the anterior leaflet of the capsule wall.

[0055] Intraocular pseudophakic contact lens 1100 also includes one or more pins 1108. Each pin 1108 projects downwardly from the outer end of haptics 1104a-1104b. Thus, pins 1108 are positioned further away from optic 1102 than pins 908. This can allow intraocular pseudophakic contact lens 1100 to be used with larger intraocular lenses. This can also allow pins 1108 to extend to or beyond the edge of the intraocular lens, which can help lock intraocular pseudophakic contact lens 1100 to the front or side surface of the intraocular lens or reduce slippage of intraocular pseudophakic contact lens 1100 on the intraocular lens.

[0056] The intraocular pseudophakic contact lens 1100 can be implanted during the same procedure in which the intraocular lens is implanted, or during a subsequent procedure after the intraocular lens has already been implanted in the patient's eye. The anterior leaflet of the capsule wall of the patient's eye can be used to capture and confine the haptics 1104a-1104b of the intraocular pseudophakic contact lens 1100 beneath the anterior leaflet, and optionally, fibrosis or refibrosis can occur to attach the haptics 1104a-1104b to the patient's eye. Pins 1108 can be used to help hold the intraocular pseudophakic contact lens 1100 in place.

[0057] Figure 13 A sixth exemplary intraocular pseudophakic contact lens 1300 according to the present disclosure is shown. Figure 13 As shown in FIG, an intraocular pseudophakic contact lens 1300 includes an optical lens 1302 and a plurality of haptics 1304a-1304c. The optical lens 1302 can be the same as or similar to the various optical lenses described above.

[0058] In this example, the haptics 1304a-1304c are formed by large protrusions extending from the sides of the optical lens 1302, wherein the protrusions have a thickness that gradually decreases toward the outer edge of the protrusions. This facilitates easier insertion of the haptics 1304a-1304c beneath the anterior leaflet of the capsule wall in the patient's eye. Each of the haptics 1304a-1304c may include a textured surface, such as a plurality of holes or other structures, that facilitates confinement, capture, or attachment to the anterior leaflet of the capsule wall. While three haptics 1304a-1304c are shown here, other numbers of haptics may also be used.

[0059] Figure 14 and Figure 15 A seventh exemplary intraocular pseudophakic contact lens 1400 according to the present disclosure is shown. In particular, Figure 14 An oblique view of an intraocular pseudophakic contact lens 1400 is shown, and Figure 15 A cross-sectional view through the middle of an intraocular pseudophakic contact lens 1400 is shown.

[0060] like Figure 14 and Figure 15 As shown in FIG, an intraocular pseudophakic contact lens 1400 includes an optical lens 1402 and a plurality of haptics 1404a-1404b. The optical lens 1402 can be the same as or similar to the various optical lenses described above. Each of the haptics 1404a-1404b can include a textured surface, such as a plurality of holes or other structures, that facilitates restriction, capture, or attachment to the anterior leaflet of the capsule wall.

[0061] In this example, haptics 1404a-1404b are formed from large protrusions extending from the sides of optical lens 1402. Each haptic 1404a-1404b includes an inner portion 1406 connected to optical lens 1402 and an outer portion 1408 connected to inner portion 1406, effectively forming a long "wing" extending from optical lens 1402. Outer portion 1408 has a thickness that tapers toward the outer edge of haptics 1404a-1404b, which facilitates easier insertion of haptics 1404a-1404b beneath the anterior leaflet of the capsule wall in the patient's eye. In this example, inner portion 1406 protrudes outward and downward, while outer portion 1408 protrudes outward and slightly upward in this example (although other configurations may also be used). This shape allows haptics 1404a-1404b to be used with larger intraocular lenses while still extending beneath the anterior leaflet of the capsule wall.

[0062] Each of the haptics 1404a-1404b also includes a ridge 1410, and the ridges 1410 of the plurality of haptics 1404a-1404b can be used to capture one or more edges of the underlying intraocular lens. This can help center the intraocular pseudophakic contact lens 1400 on the intraocular lens. This can also help maintain the intraocular pseudophakic contact lens 1400 in place on the intraocular lens during the healing process.

[0063] Figures 16 to 18 An eighth exemplary intraocular pseudophakic contact lens 1600 according to the present disclosure is shown. In particular, Figure 16 An oblique view of an intraocular pseudophakic contact lens 1600 is shown, Figure 17 A top view of an intraocular pseudophakic contact lens 1600 is shown, and Figure 18 A cross-sectional view through the middle of an intraocular pseudophakic contact lens 1600 is shown.

[0064] like Figures 16 to 18As shown in FIG, intraocular pseudophakic contact lens 1600 has various components that are the same as or similar to those forming intraocular pseudophakic contact lens 1400. For example, intraocular pseudophakic contact lens 1600 includes an optical lens 1602 and a plurality of haptics 1604a-1604b. Haptics 1604a-1604b are formed by large protrusions extending from the sides of optical lens 1602. Each haptic 1604a-1604b includes an inner portion 1606 connected to optical lens 1602 (or to a retaining ring in which optical lens 1602 is located) and an outer portion 1608 connected to inner portion 1606. Outer portion 1608 has a thickness that gradually decreases toward the outer edge of haptic 1604a-1604b, which facilitates easier insertion of haptic 1604a-1604b beneath the anterior leaflet of the capsule wall in the patient's eye. In this example, both the inner portion 1606 and the outer portion 1608 project outward and straight (although other forms may be used.) This shape allows the haptics 1604a-1604b to be used with larger intraocular lenses while still extending beneath the anterior leaflet of the capsule wall.

[0065] Each of the haptics 1604a-1604b also includes a ridge 1610, and the ridges 1610 of the plurality of haptics 1604a-1604b can be used to capture one or more edges of the underlying intraocular lens. This can help center the intraocular pseudophakic contact lens 1600 on the intraocular lens. This can also help maintain the intraocular pseudophakic contact lens 1600 in place on the intraocular lens during the healing process.

[0066] In addition, intraocular pseudophakic contact lens 1600 here includes a plurality of segments 1612 positioned along the sides of optic 1602. Segments 1612 represent protrusions from optic 1602, and at least some of segments 1612 can be coupled to haptics 1604a-1604b (e.g., when the ends of haptics 1604a-1604b are embedded in segments 1612). Segments 1612 extend downwardly so that the bottom surfaces of segments 1612 are positioned below optic 1602. Thus, when implanted in a patient's eye, segments 1612 maintain separation between optic 1602 and the underlying intraocular lens. Depending on the shape of the posterior surface of optic 1602 and the shape of the anterior surface of the underlying intraocular lens, this can allow optic 1602 to be elevated above the optic within the underlying intraocular lens, preventing the optics from contacting each other.

[0067] Each of the segments 1612 can be made of any suitable material and formed in any suitable manner. For example, each segment 1612 can represent a portion of the material forming the optical lens 1602, and therefore represent an extension of the optical lens 1602 itself. However, this need not be the case. For example, the optical lens 1602 can be placed within a retaining ring that is integral with or attached to the segment 1612, or the segment 1612 can be secured to the optical lens 1602 itself using an adhesive or other suitable connection mechanism. Each of the segments 1612 can also have any suitable size, shape, and dimensions. For example, the segment 1612 can be larger than Figures 16 to 18 As another example, segment 1612 can represent a curved structure that leaves a small open area between segment 1612 and optical lens 1602, or segment 1612 can be a solid structure that does not leave any open area between segment 1612 and optical lens 1602.

[0068] The ability to space the optical lens 1602 from the underlying intraocular lens can provide various benefits. For example, raising the optical lens 1602 above the underlying intraocular lens can allow for increased water flow between the front surface of the intraocular lens and the back surface of the optical lens 1602. The increased water flow between the lenses can help reduce lens deposits on either or both of the lenses. Moreover, the presence of water between the lenses can help improve the optical or image quality of the combined lens system. Additionally, by providing more space between the lenses, the intraocular pseudophakic contact lens 1600 can be used with a wider range of intraocular lenses having varying front curvature surfaces, thereby allowing the intraocular pseudophakic contact lens 1600 to be used with a wider range of intraocular lens models and powers.

[0069] Figures 19 to 21 A ninth exemplary intraocular pseudophakic contact lens 1900 according to the present disclosure is shown. In particular, Figure 19 An oblique view of an intraocular pseudophakic contact lens 1900 is shown, Figure 20 A top view of an intraocular pseudophakic contact lens 1900 is shown, and Figure 21 A cross-sectional view through the middle of an intraocular pseudophakic contact lens 1900 is shown.

[0070] like Figures 19 to 21As shown in FIG, intraocular pseudophakic contact lens 1900 has various components that are the same as or similar to those forming intraocular pseudophakic contact lens 1600. For example, intraocular pseudophakic contact lens 1900 includes an optical lens 1902 and a plurality of haptics 1904a-1904b. Haptics 1904a-1904b are formed by large protrusions extending from the sides of optical lens 1902. Each haptic 1904a-1904b includes an inner portion 1906 connected to optical lens 1902 (or to a retaining ring in which optical lens 1902 is located) and an outer portion 1908 connected to inner portion 1906. Each of haptics 1904a-1904b also includes a ridge 1910, and the plurality of ridges 1910 of the plurality of haptics 1904a-1904b can be used to capture one or more edges of an underlying intraocular lens. Additionally, intraocular pseudophakic contact lens 1900 includes a plurality of segments 1912 along the sides of optical lens 1902. Segments 1912 extend downwardly such that bottom surfaces of segments 1912 are located below optical lens 1902.

[0071] Compared to the corresponding components of the intraocular pseudophakic contact lens 1600, in this example, the haptics 1904a-1904b include a thicker outer portion 1908 with a larger ridge 1910. This allows the haptics 1904a-1904b to be used with even larger intraocular lenses. In addition, each of the ridges 1910 includes a lip 1911 that can facilitate capture of the underlying intraocular lens. Each of the lips 1911 represents any suitable inward protrusion from the corresponding ridge 1910.

[0072] Again, when implanted in the patient's eye, segment 1912 helps keep optic 1902 separated from the underlying intraocular lens. Depending on the shape of the posterior surface of optic 1902 and the shape of the anterior surface of the underlying intraocular lens, this can elevate optic 1902 above the optic within the underlying intraocular lens so that the optics do not contact each other. The ability to space optic 1902 from the underlying intraocular lens can provide various benefits, such as those described above with respect to intraocular pseudophakic contact lens 1600.

[0073] Figures 22 to 24 A tenth exemplary intraocular pseudophakic contact lens 2200 according to the present disclosure is shown. In particular, Figure 22 An oblique view of an intraocular pseudophakic contact lens 2200 is shown, Figure 23 A top view of an intraocular pseudophakic contact lens 2200 is shown, and Figure 24 A side view of an intraocular pseudophakic contact lens 2200 is shown.

[0074] like Figures 22 to 24 As shown in , intraocular pseudophakic contact lens 2200 has various components that are the same as or similar to the components forming intraocular pseudophakic contact lens 1400. For example, intraocular pseudophakic contact lens 2200 includes an optical lens 2202 and a plurality of haptics 2204a-2204c. Haptics 2204a-2204c are formed by protrusions extending from the sides of optical lens 2202. Each haptic 2204a-2204c includes an inner portion 2206 connected to optical lens 2202 (or to a retaining ring in which optical lens 2202 is located) and an outer portion 2208 connected to inner portion 2206. Each haptic 2204a-2204c also includes a ridge 2210, and the plurality of ridges 2210 of the plurality of haptics 2204a-2204c can be used to capture one or more edges of an underlying intraocular lens. Although not shown here, at least one of the ridges 2210 can include a lip that can be the same as or similar to lip 1911 and which can facilitate capturing and retaining an underlying intraocular lens.

[0075] In this example, the haptics 2204a-2204c are formed by a large protrusion extending from the side of the optical lens 2202, wherein the protrusion has a thickness that gradually decreases towards the outer edge of the protrusion. This facilitates easier insertion of the haptics 2204a-2204c under the anterior leaflet of the capsule wall in the patient's eye. Each haptic 2204a-2204c may include a textured surface, such as a plurality of holes or other structures, which facilitates confinement, capture or attachment to the anterior leaflet of the capsule wall. Although three haptics 2204a-2204c are shown here, other numbers of haptics may also be used. In some embodiments, the haptics 2204a-2204c may be positioned at even intervals of 120°.

[0076] Also in this example, an alignment mark 2212 is provided on one of the haptics 2204b. In this particular example, the alignment mark 2212 represents the letter "R," although any other suitable marking may be used in any suitable location. The alignment mark 2212 can be used to identify the correct orientation of the intraocular pseudophakic contact lens 2200, such as by identifying the haptic 2204b that is located on the right side of the intraocular pseudophakic contact lens 2200 after implantation (from the perspective of a surgeon or other medical professional).

[0077] Figures 25 to 27 An eleventh exemplary intraocular pseudophakic contact lens 2500 according to the present disclosure is shown. In particular, Figure 25 An oblique view of an intraocular pseudophakic contact lens 2500 is shown, Figure 26 A top view of an intraocular pseudophakic contact lens 2500 is shown, and Figure 27A side view of an intraocular pseudophakic contact lens 2500 is shown.

[0078] like Figures 25 to 27 As shown in , intraocular pseudophakic contact lens 2500 has various components that are the same as or similar to the components forming intraocular pseudophakic contact lens 2200. For example, intraocular pseudophakic contact lens 2500 includes an optical lens 2502 and a plurality of haptics 2504a-2504d. Haptics 2504a-2504d are formed by protrusions extending from the sides of optical lens 2502. Each haptic 2504a-2504d includes an inner portion 2506 connected to optical lens 2502 (or to a retaining ring in which optical lens 2502 is located) and an outer portion 2508 connected to inner portion 2506. Each of haptics 2504a-2504d also includes a ridge 2510, and the plurality of ridges 2510 of the plurality of haptics 2504a-2504d can be used to capture one or more edges of an underlying intraocular lens. Although not shown here, at least one of the ridges 2510 can include a lip that can be the same as or similar to lip 1911 and can facilitate capturing and retaining an underlying intraocular lens.

[0079] In this example, the haptics 2504a-2504d are formed by large protrusions extending from the sides of the optical lens 2502, wherein the protrusions have a thickness that gradually decreases toward the outer edge of the protrusions. This facilitates easier insertion of the haptics 2504a-2504d under the anterior leaflet of the capsule wall in the patient's eye. Each of the haptics 2504a-2504d may include a textured surface, such as a plurality of holes or other structures, which facilitates restriction, capture, or attachment to the anterior leaflet of the capsule wall. Although the four haptics 2504a-2504d are shown here as two groups on opposite sides of the optical lens 2502, other numbers and arrangements of haptics may also be used.

[0080] Figures 28 to 30 A twelfth exemplary intraocular pseudophakic contact lens 2800 according to the present disclosure is shown. In particular, Figure 28 shows a top view of an intraocular pseudophakic contact lens 2800, Figure 29 A side view of an intraocular pseudophakic contact lens 2800 is shown, and Figure 30 A bottom view of an intraocular pseudophakic contact lens 2800 is shown.

[0081] like Figures 28 to 30As shown in FIG, intraocular pseudophakic contact lens 2800 has various components that are the same as or similar to the components forming intraocular pseudophakic contact lens 2200. For example, intraocular pseudophakic contact lens 2800 includes an optical lens 2802 and a plurality of haptics 2804. Haptics 2804 are formed by protrusions extending from the sides of optical lens 2802. Each haptic 2804 includes an inner portion 2806 connected to optical lens 2802 (or to a retaining ring in which optical lens 2802 is located) and an outer portion 2808 connected to inner portion 2806. Each haptic 2804 also includes a ridge 2810, and the plurality of ridges 2810 of the plurality of haptics 2804 can be used to capture one or more edges of an underlying intraocular lens. Although not shown here, at least one of the ridges 2810 can include a lip that can be the same as or similar to lip 1911, and this lip can facilitate capturing and retaining the underlying intraocular lens.

[0082] In this example, haptics 2804 are formed from large protrusions extending from the sides of optical lens 2802, wherein the protrusions have a thickness that tapers toward the outer edge of the protrusions. This facilitates easier insertion of haptics 2804 beneath the anterior leaflet of the cystic wall in the patient's eye. Each haptic 2804 may include a textured surface, such as a plurality of holes or other structures, that facilitates confinement, capture, or attachment to the anterior leaflet of the cystic wall. While three haptics 2804 are shown here, other numbers and arrangements of haptics may also be used.

[0083] In this example, the optic 2802 of the intraocular pseudophakic contact lens 2800 includes a first lens portion 2812 and a second lens portion 2814. The two portions 2812 and 2814 of the optic 2802 can be used to provide different levels of optical power. In this example, for example, the first lens portion 2812 can provide a specified amount of power (or perhaps little or no power), and the second lens portion 2814 can provide a higher specified amount of power. In some embodiments, the second lens portion 2814 can represent a "full segment" of increased power compared to the first lens portion 2812. Note that the amount of power provided by each lens portion 2812-2814 may or may not be based on any residual refractive error in the patient's eye. It should also be noted that while the lens portion 2814 with additional power is positioned at the bottom of the optic 2802, the lens portion with additional power can be positioned at any other suitable location(s) or along any other suitable axis(es) of the optic 2802. It should also be noted that the size and shape of the lens portions 2812-2814 can be varied as needed or desired.

[0084] Figures 31 to 33A thirteenth exemplary intraocular pseudophakic contact lens 3100 according to the present disclosure is shown. In particular, Figure 31 shows a top view of an intraocular pseudophakic contact lens 3100, Figure 32 A side view of an intraocular pseudophakic contact lens 3100 is shown, and Figure 33 A bottom view of an intraocular pseudophakic contact lens 3100 is shown.

[0085] like Figures 31 to 33 As shown in FIG, intraocular pseudophakic contact lens 3100 has various components that are the same as or similar to the components forming intraocular pseudophakic contact lens 2800. For example, intraocular pseudophakic contact lens 3100 includes an optical lens 3102 and a plurality of haptics 3104. Haptics 3104 are formed by protrusions extending from the sides of optical lens 3102. Each haptic 3104 includes an inner portion 3106 connected to optical lens 3102 (or to a retaining ring in which optical lens 3102 is located) and an outer portion 3108 connected to inner portion 3106. Each haptic 3104 also includes a ridge 3110, and the plurality of ridges 3110 of the plurality of haptics 3104 can be used to capture one or more edges of an underlying intraocular lens. Although not shown here, at least one of the ridges 3110 can include a lip that can be the same as or similar to lip 1911 and can facilitate capturing and retaining the underlying intraocular lens.

[0086] In this example, the haptics 3104 are formed from large protrusions extending from the sides of the optical lens 3102, wherein the protrusions have a thickness that tapers toward the outer edge of the protrusions. This facilitates easier insertion of the haptics 3104 beneath the anterior leaflet of the cystic wall in the patient's eye. Each haptic 3104 may include a textured surface, such as a plurality of holes or other structures, that facilitates containment, capture, or attachment to the anterior leaflet of the cystic wall. While three haptics 3104 are shown here, other numbers and arrangements of haptics may also be used.

[0087] In this example, the optical lens 3102 of the intraocular pseudophakic contact lens 3100 includes a first lens portion 3112 and a second lens portion 3114. The two portions 3112-3114 of the optical lens 3102 can be used to provide different levels of optical magnification. In this example, for example, the first lens portion 3112 can provide a specified amount of magnification (or perhaps little or no magnification), and the second lens portion 3114 can provide a higher specified amount of magnification. Note that the amount of magnification provided by each lens portion 3112-3114 may or may not be based on any residual refractive error in the patient's eye. It should also be noted that although the lens portion 3114 with additional magnification is placed in the center of the optical lens 3102, the lens portion with additional magnification can be placed in any other suitable (one or more) positions or along any other suitable one or more axes of the optical lens 3102. It is further noted that the size and shape of the lens portions 3112-3114 can vary as needed or desired.

[0088] Figures 34 to 36 A fourteenth exemplary intraocular pseudophakic contact lens 3400 according to the present disclosure is shown. In particular, Figure 34 shows a top view of an intraocular pseudophakic contact lens 3400, Figure 29 A side view of an intraocular pseudophakic contact lens 3400 is shown, and Figure 36 A bottom view of an intraocular pseudophakic contact lens 3400 is shown.

[0089] like Figures 34 to 36 As shown in , intraocular pseudophakic contact lens 3400 has various components that are the same or similar to the components forming intraocular pseudophakic contact lens 2800. For example, intraocular pseudophakic contact lens 3400 includes an optical lens 3402 and a plurality of haptics 3404. Haptics 3404 are formed by protrusions extending from the sides of optical lens 3402. Each haptic 3404 includes an inner portion 3406 connected to optical lens 3402 (or to a retaining ring in which optical lens 3402 is located) and an outer portion 3408 connected to inner portion 3406. Each haptic 3404 also includes a ridge 3410, and the plurality of ridges 3410 of the plurality of haptics 3404 can be used to capture one or more edges of an underlying intraocular lens. Although not shown here, at least one of the ridges 3410 can include a lip that can be the same or similar to lip 1911 and can facilitate capturing and retaining the underlying intraocular lens.

[0090] In this example, the haptics 3404 are formed by large protrusions extending from the sides of the optical lens 3402, wherein the protrusions have a thickness that tapers toward the outer edge of the protrusions. This facilitates easier insertion of the haptics 3404 beneath the anterior leaflet of the cystic wall in the patient's eye. Each haptic 3404 may include a textured surface, such as a plurality of holes or other structures, that facilitates confinement, capture, or attachment to the anterior leaflet of the cystic wall. While three haptics 3404 are shown here, other numbers and arrangements of haptics may also be used.

[0091] In this example, the optic 3402 of the intraocular pseudophakic contact lens 3400 includes a first lens portion 3412 and a second lens portion 3414. The two portions 3412-3414 of the optic 3402 can be used to provide different levels of optical magnification. In this example, for example, the first lens portion 3412 can provide a specified amount of magnification (or perhaps little or no magnification), and the second lens portion 3414 can provide a higher specified amount of magnification. In some embodiments, the second lens portion 3414 can represent a "small segment" of increased magnification compared to the first lens portion 3412. Note that the amount of magnification provided by each lens portion 3412-3414 may or may not be based on any residual refractive error in the patient's eye. It should also be noted that while the lens portion 3414 with additional magnification is positioned near the bottom of the optic 3402, the lens portion with additional magnification can be positioned at any other suitable location(s) or along any other suitable axis(es) of the optic 3402. It should also be noted that the size and shape of the lens portions 3412-3414 can vary as needed and desired.

[0092] While various existing methods have secured "add-on" lenses to intraocular lenses, these existing methods require that the specific add-on lens be designed for use with the specific intraocular lens, and that the specific intraocular lens be designed for use with the specific add-on lens. That is, the add-on lens can only be used with a specific type of intraocular lens, where the intraocular lens is specifically designed for use with the add-on lens. As specific examples, the add-on lens may include haptics or other structures designed to mate with corresponding structures of a specific intraocular lens, or the intraocular lens may have a recess designed to receive a specific type of add-on lens. This can be problematic for a variety of reasons. For example, many patients already have existing intraocular lenses, and attempting to remove those existing intraocular lenses in order to implant a new intraocular lens designed for use with an add-on lens may be impractical or even dangerous.

[0093] Figures 1 to 36The embodiments of the intraocular pseudophakic contact lens shown in can help alleviate these problems because the intraocular pseudophakic contact lens can be secured over the intraocular lens by using the anterior leaflet of the capsule wall to capture and constrain the haptics of the intraocular pseudophakic contact lens. In some cases, this may also involve the haptics being physically bonded to the anterior leaflet of the capsule wall, such as via a fibrosis or refibrosis mechanism. In other words, the intraocular pseudophakic contact lens does not need to be designed to work specifically with the specific structure of any particular intraocular lens. The intraocular lens used with the intraocular pseudophakic contact lens does not need to have any predefined structure that is provided for coupling to the intraocular pseudophakic contact lens. Instead, Figures 1 to 36 The intraocular pseudophakic contact lens may simply be sized so that, when placed over the intraocular lens, it is held in place by being captured and constrained by (and possibly bonded to) the anterior leaflet of the capsule wall. This allows Figures 1 to 36 The intraocular pseudophakic contact lenses of ® are used with a variety of intraocular lenses, including different types of intraocular lenses, and including existing intraocular lenses that are already implanted in the patient. In order to install the new intraocular lens and intraocular pseudophakic contact lenses, the existing intraocular lens does not need to be removed from the patient.

[0094] In addition, it can be easily removed from the patient's eye Figures 1 to 36 The invention also provides for the removal of an intraocular pseudophakic contact lens, such as at any suitable time after implantation or before bonding of the haptics to the capsule wall (assuming fibrosis or refibrosis holds the intraocular pseudophakic contact lens in place). This allows one intraocular pseudophakic contact lens to be removed and replaced with a different intraocular pseudophakic contact lens if, among other things, a different refractive or other vision correction is needed or desired.

[0095] The various intraocular pseudophakic contact lenses described above can have any suitable size, shape, and dimensions. For example, intraocular pseudophakic contact lenses can be obtained in a range of diameters from about 4 mm to about 6 mm. Furthermore, intraocular pseudophakic contact lenses can be obtained with varying base curvatures for their optics. Of course, intraocular pseudophakic contact lenses can also be custom designed for a specific patient's eye, such as when one or more specific curvatures are required to correct residual refractive error in a specific patient's eye or to provide other desired vision correction.

[0096] The intraocular pseudophakic contact lens disclosed herein can be non-invasively implanted in a patient's eye and easily positioned over the intraocular lens. The implantation is non-invasive because the intraocular pseudophakic contact lens is mounted on the anterior surface of the intraocular lens, which is generally easily accessible to the surgeon or other personnel during the implantation procedure. The implantation is also non-invasive because the intraocular pseudophakic contact lens can be attached to the intraocular lens without requiring attachment of the intraocular pseudophakic contact lens to anatomical structures within the patient's eye, such as the ciliary sulcus of the patient's eye.

[0097] The non-invasive implantation and easy positioning of the intraocular pseudophakic contact lens provide for safe and effective refractive surgical procedures for correcting unwanted residual refractive error, such as after a phakic procedure, or providing some other desired vision correction. As a refractive modality, the intraocular pseudophakic contact lens facilitates the surgeon's ability to modify a pseudophakic patient's current refractive error or otherwise alter the patient's vision in an attempt to adjust the patient's vision to achieve a finely tuned desired refraction. Specific examples of this functionality include: allowing accommodation of the patient's eye to achieve unilateral or bilateral emmetropia, inducing unilateral myopia to allow intermediate and near vision function, introducing multifocality, and treating unwanted residual astigmatism.

[0098] If the haptics of the intraocular lens include ridges along its bottom surface, the ridges can be used to center the intraocular lens on the underlying intraocular lens as described above. If the intraocular lens includes three haptics with associated ridges, the ridges can help to perfectly center the intraocular lens on the underlying intraocular lens. This approach allows the ridges of the haptics of the intraocular lens to capture the underlying intraocular lens at the edges and perfectly align the optical center of the optic of the intraocular lens with the optical center of the intraocular lens. This alignment helps to reduce or avoid induced optical aberrations or induced prism caused by misalignment of the optical centers. This provides a strong contributing benefit over conventional forms of refractive fine-tuning.

[0099] It should be noted that in any of the above examples, the intraocular pseudophakic contact lens may be designed so that only the haptics of the intraocular pseudophakic contact lens extend beneath the anterior leaflet of the capsule wall in the patient's eye. This allows the haptics to be captured and constrained by the anterior leaflet, while leaving the optic of the intraocular pseudophakic contact lens free and generally unobstructed by surrounding tissue in the patient's eye.

[0100] It should also be noted that, in some embodiments, the surgical tool disclosed in U.S. Patent Application No. 16 / 280,235 (the entire contents of which are incorporated herein by reference) can be used to assist in implanting an intraocular pseudophakic contact lens. For example, the tool can be used to separate at least a portion of the anterior leaflet of a patient's eye from an implanted intraocular lens, thereby allowing a haptic of the intraocular pseudophakic contact lens to be inserted between the anterior leaflet and the intraocular lens. As another example, such a tool can be used to separate the anterior leaflet of a patient's eye from an implanted intraocular pseudophakic contact lens, allowing the intraocular pseudophakic contact lens to be removed (and possibly replaced).

[0101] Furthermore, it should be understood from the above description that a variety of optical lenses or other optical devices can be used as the optical lens for any given intraocular pseudophakic contact lens. This enables intraocular pseudophakic contact lenses to be used to provide a variety of vision corrections in a patient's eye when combined with an intraocular lens in the patient's eye. As described above, for example, intraocular pseudophakic contact lenses can be used to help correct myopia, hyperopia, and / or astigmatism refractive errors in a patient's eye. As other examples, intraocular pseudophakic contact lenses can be used to provide magnification for low vision patients, provide guided focus through an adjusted prism, and / or provide a variable aperture (such as a pinhole, cat's eye structure, and / or a narrow slit). As other examples, intraocular pseudophakic contact lenses can be used to provide various forms of vision correction (such as multifocal, astigmatism, depth of focus, asymmetric cornea, and / or photochromic correction), to provide drug delivery, to provide UV protection, and / or to support dysphotopsia treatment. In general, the present disclosure is not limited to any particular type or shape of optical lens in an intraocular pseudophakic contact lens, or to any particular type of treatment using an intraocular pseudophakic contact lens.

[0102] Although Figures 1 to 36 An example of an artificial pseudophakic contact lens is shown, but Figures 1 to 36 Make various changes. For example, Figures 1 to 36 Any suitable combination of features shown in can be used together in a single intraocular pseudophakic contact lens, regardless of whether that particular combination of features is shown in the drawings or discussed above. As a specific example, Figures 1 to 36Any of the intraocular pseudophakic contact lenses shown in the drawings can include one or more pins at one or more desired locations, one or more ridges along the bottom surface of its haptics to assist in capturing and centering the intraocular lens, and / or one or more lips to assist in capturing the intraocular lens. Moreover, each intraocular pseudophakic contact lens can include any suitable number of each component shown in any of the figures. Although the figures have shown the intraocular pseudophakic contact lenses as having two, three, or four haptics (some at evenly spaced intervals of 120° or 180°), any number of haptics (with or without associated pins, ridges, lips, or other structures) can be used. Furthermore, the forms of haptics shown here are examples only, and any other suitable structure can be used to capture, constrain, or attach to the anterior leaflet of the capsule wall in the patient's eye. Additionally, a number of other features can be used at one or more locations on the intraocular pseudophakic contact lens. For example, one or more alignment marks may be provided to identify proper alignment of the intraocular lens with the intraocular lens, or one or more drug eluting materials may be placed on the top, side, or bottom surface of the optic in the intraocular lens.

[0103] Figure 37 An exemplary intraocular lens and an exemplary intraocular pseudophakic contact lens are shown in a patient's eye 3700 according to the present disclosure. Figure 37 , eye 3700 includes cornea 3702, sclera 3704, and iris 3706. Cornea 3702 represents the transparent front portion of eye 3700 through which light enters eye 3700. Sclera 3704 is the tough outer white portion of the eye. Iris 3706 controls the size of the pupil of the eye, thereby controlling the amount of light from cornea 3702 that enters the interior of eye 3700.

[0104] The eye 3700 also includes a capsular bag 3708, which typically houses the natural lens of the eye 3700. However, in this example, the natural lens has been removed and replaced with an intraocular lens 3710 having an optic 3712 and one or more haptics 3714. The optic 3712 of the intraocular lens 3710 receives light entering the eye and focuses the light onto the retina of the eye 3700. The haptics 3714 of the intraocular lens 3710 help maintain the intraocular lens 3710 within the capsular bag 3708 so that the optic 3712 of the intraocular lens 3710 is in a desired position within the eye.

[0105] An intraocular lens 3716 has also been placed over the intraocular lens 3710 within the capsular bag 3708. The intraocular lens 3716 can represent any of the intraocular lens described above or any other suitable intraocular lens. The intraocular lens 3716 is placed on the anterior surface of the intraocular lens 3710 (i.e., the front surface of the intraocular lens 3710 relative to the eye 3700). Light enters through the cornea 3702 and passes through the pupil before entering the intraocular lens 3716, which changes the light. The changed light then passes through the optic 3712 of the intraocular lens 3710 and is changed again. The twice-changed light then travels through the rest of the eye 3700 to reach the retina at the back of the eye 3700.

[0106] As described above, the intraocular pseudophakic contact lens 3716 includes one or more haptics that extend a short distance and fit beneath the anterior leaflet 3718 of the capsular bag 3708. This allows the haptics to be captured and confined by the anterior leaflet 3718 (and potentially attached to the anterior leaflet 3718 via fibrosis or refibrosis). The anterior leaflet 3718 represents the outer portion of the anterior side of the capsular bag 3708 that remains after a capsulorrhexis is formed in the capsular bag 3708. The insertion of the haptics of the intraocular pseudophakic contact lens 3716 beneath the anterior leaflet 3718 helps secure the intraocular pseudophakic contact lens 3716 in place. In some cases, the healing process in the eye 3700 can cause fibrosis to occur, which can also cause the anterior leaflet 3718 to attach to the haptics of the intraocular pseudophakic contact lens 3716.

[0107] It should be noted that the haptics of the intraocular pseudophakic contact lens 3716 are shorter or smaller than the haptics 3714 of the intraocular lens 3710. This is because the haptics 3714 of the intraocular lens 3710 typically extend to the top and bottom of the capsular bag 3708 and help to hold the intraocular lens 3710 in place within the capsular bag 3708. The haptics of the intraocular pseudophakic contact lens 3716 do not need to extend to the top and bottom of the capsular bag 3708, but may extend only a short distance below the anterior leaflet 3718.

[0108] By appropriately selecting the optics of the intraocular pseudophakic contact lens 3716, the intraocular pseudophakic contact lens 3716 can ideally correct any residual refractive error remaining after implantation of the intraocular lens 3710 or providing any other desired vision correction in the patient's eye 3700. If desired, the intraocular pseudophakic contact lens 3716 can also be removed and replaced with a different intraocular pseudophakic contact lens. This may be necessary or desirable if the intraocular pseudophakic contact lens 3716 is not properly correcting the residual refractive error, if the intraocular pseudophakic contact lens 3716 is actually causing additional refractive error, or if some other form of vision correction is needed or desired.

[0109] Although Figure 37 An example of an intraocular lens in a patient's eye and an example of an intraocular pseudophakic contact lens are shown, but Figure 37 Various changes can be made. For example, intraocular lens 3710 can be attached to any other intraocular pseudophakic contact lens. Moreover, there are multiple intraocular lenses available, and the intraocular pseudophakic contact lens can be coupled to any other suitable intraocular lens in eye 3700.

[0110] Figure 38 An exemplary method 3800 for using an intraocular pseudophakic contact lens with an intraocular lens according to the present disclosure is shown. Figure 38 As shown in , at step 3802, residual refractive error in the eye of a patient with an intraocular lens is identified. This can include, for example, personnel testing the patient's vision and identifying any refractive error that remains after implantation of the intraocular lens 3710. The test can be performed in any suitable manner, such as by using intraoperative wavefront aberration measurement. One purpose of the test can be to identify what refractive error is present in the patient's eye after the intraocular lens is implanted in the patient's eye. This test can be performed at any suitable time, such as after a phakic procedure. However, note that this step is optional, as intraocular pseudophakic contact lenses can be used to provide other forms of vision correction in the patient's eye and do not necessarily need to correct residual refractive error.

[0111] At step 3804, an intraocular pseudophakic contact lens (IOPCL) is selected, such as to correct the identified residual refractive error or provide some other form of vision correction. This may include, for example, the personnel selecting an IOPCL from a kit, wherein the selected IOPCL has an optic that substantially cancels the identified residual refractive error. This may also include the personnel selecting an optic from the kit and inserting the optic into the IOPCL, wherein the selected optic substantially eliminates the identified residual refractive error. This may also include the personnel obtaining an IOPCL with a custom-designed optic or obtaining a custom-designed optic for insertion into the IOPCL, wherein the custom-designed optic substantially eliminates the identified residual refractive error. Furthermore, this may include the personnel obtaining (by whatever means) an IOPCL that provides the desired amount of power, multifocality, or other form of vision correction. Generally, any suitable IOPCL may be obtained using any means.

[0112] The selected intraocular lens is inserted into the patient's eye at step 3806. This may include, for example, a surgeon or other personnel making a small incision in the patient's eye and inserting the intraocular lens through the incision. The intraocular lens may be rolled, folded, or otherwise reduced in cross-sectional size to facilitate insertion of the intraocular lens through the smaller incision.

[0113] At step 3808, one or more haptics of the intraocular pseudophakic contact lens are inserted into the patient's eye beneath the anterior leaflet of the capsular wall. This may include, for example, the surgeon or other personnel placing the intraocular pseudophakic contact lens 3716 at a desired location (and possibly in a desired orientation) on the intraocular lens 3710. This may also include the surgeon or other personnel moving the intraocular pseudophakic contact lens 3716 so that its haptics (in whatever form) slide beneath the anterior leaflet 3718 of the capsular bag 3708.

[0114] A vision test of the patient occurs at step 3810. The vision test may be performed in any suitable manner, such as by using intraoperative wavefront aberration measurement. This vision test may also be performed at any suitable time, such as during a surgical procedure in which an intraocular pseudophakic contact lens is being implanted, or after the surgical procedure has been completed. A determination is made at step 3812 whether the tested vision is satisfactory. This may include, for example, personnel determining whether the patient's eye is still experiencing any residual refractive error, and if so, to what extent. This may also include personnel determining whether the patient's eye requires additional magnification, multifocal, or other forms of vision correction.

[0115] At step 3814, a determination is made as to whether to replace the intraocular lens. This may include, for example, personnel and the patient determining whether the remaining residual refractive error, if any, is inconvenient or otherwise problematic for the patient, or otherwise determining whether the current vision correction is adequate. If so, various steps may be taken to attempt to resolve the issue. For example, the currently implanted intraocular lens may be repositioned to adjust for cylindrical axis correction. If this fails, another intraocular lens is selected at step 3816. This may include, for example, personnel selecting another intraocular lens that (ideally) provides better refractive correction or other vision correction for the patient's eye than the currently inserted intraocular lens. At step 3818, the currently inserted intraocular lens is removed from the patient's eye. This may include, for example, the surgeon or other personnel sliding the haptics of the currently inserted intraocular lens 3716 from beneath the anterior leaflet 3718 and removing the currently inserted intraocular lens 3716 from the patient's eye. The process then returns to step 3806 where the newly selected intraocular pseudophakic contact lens can be inserted into the patient's eye and the vision test can be repeated.

[0116] exist Figure 38 After the process shown in FIG is complete, the haptics of the implanted intraocular pseudophakic contact lens 3716 can be captured / restricted in the patient's eye by the anterior leaflet 3718 of the capsular bag 3708. This helps to keep the intraocular pseudophakic contact lens 3716 in place. Additionally, the healing process in the patient's eye can optionally cause fibrosis or refibrosis to occur, which can physically attach the haptics of the implanted intraocular pseudophakic contact lens 3716 to the anterior leaflet 3718 of the capsular bag 3708.

[0117] Although Figure 38 One example of a method 3800 for using an intraocular pseudophakic contact lens with an intraocular lens is shown, but may be used with Figure 38 For example, although shown as a series of steps, Figure 38 The various steps in the process may overlap, occur in parallel, occur in a different order, or occur any number of times.
