Description

[Technical field]

[0001] The present disclosure relates generally to implantable optical devices, and more particularly to intraocular pseudophakic contact lenses with fixation mechanisms via the anterior apex of the capsular bag wall, and related systems and methods. [Background technology]

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

[0003] Before placing an intraocular lens in a patient's eye, a physician or other practitioner will typically select an intraocular lens designed to provide the desired refractive correction for the patient's eye. For example, an intraocular lens can be an optical lens designed to correct the patient's eye's naturally occurring myopia (nearsightedness), hyperopia (farsightedness), astigmatism, or other refractive error. However, it is often the case that the intraocular lens selected for the patient's eye does not fully correct (or may even cause) some refractive error in the patient's eye. This refractive error is referred to as "residual" refractive error.

[0004] There are various methods to correct residual refractive error, all of which have their drawbacks. For example, one intraocular lens in the patient's eye can be replaced with another, but this usually comes with a high risk of surgical complications. Ablative procedures (such as LASIK) can be performed on the cornea of ​​the patient's eye to correct the residual refractive error, but this can lead to high levels of unwanted side effects, especially for older patients. An additional intraocular lens (often called a "piggyback" IOL) can be inserted in front of the existing intraocular lens, but this is usually an invasive procedure with low predictability regarding the final refractive outcome. An intracorneal lens (ICL) can also be inserted into the cornea of ​​the patient's eye, but this is often highly invasive and has a high rejection rate. In general, the above procedures are usually unpredictable and involve high surgical risks. Also, the devices used in the above procedures make it difficult to remove or "reverse" the residual refractive error, which results in a high risk of leaving the patient with induced visual abnormalities. Summary of the Invention

[0005] In accordance with the present disclosure, an intraocular pseudophakic contact lens with a fixation mechanism by the anterior apex of the capsular bag wall, and related systems and methods, are provided.

[0006] In a first embodiment, the device comprises an intraocular pseudophakic contact lens. The intraocular pseudophakic contact lens includes an optical lens configured to at least partially correct a residual refractive error of the eye. The residual refractive error includes a refractive error present in the eye after implantation of the artificial intraocular lens in the eye. The intraocular pseudophakic contact lens also includes one or more haptics configured to be inserted under the anterior apex to capture and confine the one or more haptics under the anterior apex of the capsular bag wall of the eye and secure the intraocular pseudophakic contact lens to the artificial intraocular lens.

[0007] In a second embodiment, a system includes an artificial intraocular lens and an intraocular pseudophakic contact lens. The intraocular pseudophakic contact lens includes an optical lens configured to at least partially correct a residual refractive error of the eye. The residual refractive error includes a refractive error present in the eye after implantation of the artificial intraocular lens in the eye. The intraocular pseudophakic contact lens also includes one or more haptics configured to be inserted under the anterior apex to capture and confine the one or more haptics under the anterior apex of a capsular bag wall of the eye and secure the intraocular pseudophakic contact lens relative to the artificial intraocular lens.

[0008] In a third embodiment, a system includes an artificial intraocular lens and an intraocular pseudophakic contact lens. The artificial intraocular lens includes a first optic and a first haptic configured to position the artificial intraocular lens in the eye. The intraocular pseudophakic contact lens includes a second optic configured to at least partially correct a residual refractive error of the eye. The residual refractive error includes a refractive error present in the eye after implantation of the artificial intraocular lens in the eye. The intraocular pseudophakic contact lens also includes a second haptic configured to be inserted under the anterior apex to capture and confine the second haptic under the anterior apex of a capsular wall of the eye and secure the intraocular pseudophakic contact lens relative to the artificial intraocular lens. The intraocular pseudophakic contact lens further includes a plurality of segments disposed about the second optic. A bottom surface of each segment is located below a posterior surface of the second optic of the intraocular pseudophakic contact lens. The segments are configured to elevate the optic above the artificial intraocular lens.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] 1-23 discussed below, and the various embodiments used to illustrate the principles of the present invention in this patent document, are exemplary only and should not be construed as limiting the scope of the invention in any way. Those skilled in the art will understand that the principles of the present invention may be implemented in any suitably configured device or system.

[0013] The present disclosure provides various intraocular pseudophakic contact lenses (IOPCLs) that can be used in combination with intraocular lenses (IOLs). Intraocular pseudophakic contact lenses are generally contact lens type devices that can be implanted in a patient's eye and placed in front of an intraocular lens in the patient's eye. Intraocular pseudophakic contact lenses substantially correct residual refractive error that exists after implantation of an intraocular lens, such as after a lensectomy (cataract) procedure. In addition, intraocular pseudophakic contact lenses include haptics or other mechanisms that allow the intraocular pseudophakic contact lens to be trapped / captured by the anterior apex of the capsular bag wall of the patient's eye. In some cases, the haptics or other mechanisms actually attach to the anterior apex of the capsular bag wall, such as through fibrosis during the healing process, to help secure the intraocular pseudophakic contact lens in place.

[0014] Unlike traditional approaches, intraocular pseudophakic contact lenses can be implanted with fewer surgical risks. In addition, intraocular pseudophakic contact lenses allow patients to see immediately after implantation of the intraocular pseudophakic contact lens. Furthermore, if a different lens is needed to correct residual refractive error, the intraocular pseudophakic contact lens can be easily replaced or even removed if necessary. Furthermore, currently available technologies such as intraoperative wavefront aberrometry allow the refractive outcome to be measured during the actual procedure when the intraocular pseudophakic contact lens is implanted, making it useful for immediately identifying when the desired refractive target has been achieved.

[0015] 1 to 3 show a first example of an intraocular pseudophakic contact lens 100 according to the present disclosure. Specifically, Fig. 1 shows a perspective view of the intraocular pseudophakic contact lens 100, Fig. 2 shows a top view of the intraocular pseudophakic contact lens 100, and Fig. 3 shows a side view of the intraocular pseudophakic contact lens 100.

[0016] As shown in Figures 1-3, an intraocular pseudophakic contact lens 100 includes an optical lens 102. The optical lens 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 the optical lens 102 passes through an associated intraocular lens before reaching the retina of the patient's eye.

[0017] The optical lenses 102 may be formed from any suitable material, such as silicone or acrylic. The optical lenses 102 may also be formed in any suitable manner, such as using a mold or lathe cutting manufacturing process. A wide range of diopters can be achieved by designing and manufacturing different lenses 102, and each optical lens 102 may be designed to correct any suitable refractive error. Examples of types of refractive errors that can be corrected include myopia, hyperopia, and astigmatism.

[0018] The optical lens 102 in this example has a convex top surface and a concave bottom surface. However, the optical lens 102 may have other suitable shapes, which may depend (at least in part) on the type of refractive error to be corrected. As specific examples, the optical lens 102 may be convex, concave, spherical, aspheric, toric, monofocal, or multifocal. The particular lens platform used as the optical lens 102 of the intraocular pseudophakic contact lens 100 may be selected to provide the desired refractive correction for the patient's eye. The optical lens 102 may also include various other features as needed or desired, such as when the optical lens 102 (such as at the bottom) is weighted so that the optical lens 102 is oriented in a desired direction on the intraocular lens (as in the case of a toric platform), when the optical lens 102 is tinted, photochromic, or includes ultraviolet (UV) absorbers.

[0019] The plurality of haptics 104a-104b extend from the plurality of sides of the optical lens 102. The haptics 104a-104b extend a short distance from the optical lens 102 and are sized and shaped to fit under the anterior apex of the capsular bag wall of the patient's eye after implantation. Each of the haptics 104a-104b may be formed from any suitable material and in any suitable manner. For example, each of the haptics 104a-104b may be formed from the same material as the optical lens 102. It is noted that although two haptics 104a-104b are shown, the intraocular pseudophakic contact lens 100 may include any number of haptics, including a single haptic. It is also noted that although the haptics 104a-104b are curved downward, the haptics 104a-104b may be in any other suitable configuration.

[0020] In this example, the haptics 104a-104b are spaced from the optical lens 102 by protrusions or extensions 106 that protrude from the sides of the optical lens 102. These extensions 106 are portions of the intraocular pseudophakic contact lens 100 into which the ends of the haptics 104a-104b may be embedded. Each extension 106 may be formed from any suitable material and in any suitable manner. For example, each extension 106 may be a portion of the material forming the optical lens 102, and thus an extension of the optical lens 102 itself. However, this need not be the case. For example, the optical lens 102 may be disposed within a retaining ring that is integral with or attached to the extension 106, or the extension 106 may be secured to the optical lens 102 itself using an adhesive or other suitable attachment mechanism.

[0021] It should be noted that while two extensions 106 are shown, the intraocular pseudophakic contact lens 100 may include any number of extensions, including a single extension. It should also be noted that the extensions 106 may be absent and the haptics 104a-104b may be directly integrated with the optical lens 102. In these embodiments, the haptics 104a-104b may be part of the material forming the optical lens 102, although this need not be the case. For example, the optical lens 102 may be disposed 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 attachment mechanism.

[0022] Each haptic 104a-104b has a textured surface 108 formed by various holes formed, in this example, partially or completely through the haptic 104a-104b. The textured surface 108 allows the haptic 104a-104b to be captured and trapped by the anterior apex of the capsular bag wall of the patient's pseudophakic eye. In some cases, the textured surface 108 allows the haptic 104a-104b to actually physically bond with the anterior apex of the capsular bag wall of the patient's eye, such as through fibrosis during the healing process. The haptics 104a-104b are useful for securing the intraocular pseudophakic contact lens 100 in place on the intraocular lens. It is noted that the number and size of holes in the textured surface 108 are exemplary only, and the haptics 104a-104b may include different numbers and sizes of holes. For example, haptics 104a-104b may have numerous very small holes or other structures that create a texture that promotes containment, capture, or attachment to the anterior apex of the capsular bag wall.

[0023] The anterior apex of the capsular bag wall of a patient's eye is typically formed during a capsulotomy, where the patient's eye's natural lens is removed and replaced with an intraocular lens. The anterior apex is the outer portion of the anterior surface of the capsular bag that remains after an opening (called a capsulotomy) is made in the capsular bag so that the natural lens can be removed. This may occur long before the intraocular pseudophakic contact lens 100 is implanted. After the capsulotomy, the anterior apex of the capsular bag wall typically shrinks and undergoes fibrosis during the healing process.

[0024] When the intraocular pseudophakic contact lens 100 is inserted into the patient's eye, the intraocular pseudophakic contact lens 100 can be positioned such that the haptics 104a-104b extend below the anterior apex of the patient's eye. This allows the haptics 104a-104b to become captured and trapped by the anterior apex. The haptics 104a-104b may become physically attached to the anterior apex over time, for example, by "refibrosis" of the anterior apex. This tissue refibrosis may bond to and cover some or all of the haptics 104a-104b, further securing the intraocular pseudophakic contact lens 100 in place. However, implantation of the intraocular pseudophakic contact lens 100 may be performed in the same procedure as implantation of an intraocular lens. In that case, the intraocular pseudophakic contact lens 100 may be secured by the haptics 104a-104b, possibly during fibrosis (not refibrosis) in the patient's eye.

[0025] 4 and 5 show a second example of an intraocular pseudophakic contact lens 400 according to the present disclosure. Specifically, Fig. 4 shows a perspective view of the intraocular pseudophakic contact lens 400, and Fig. 5 shows a side view of the intraocular pseudophakic contact lens 400.

[0026] 4-5, intraocular pseudophakic contact lens 400 has various components that are the same or similar to those that form intraocular pseudophakic contact lens 100. For example, intraocular pseudophakic contact lens 400 includes an optical lens 402, a number of haptics 404a-404b, and, optionally, a number of extensions 406. Haptics 404a-404b include textured surfaces 408.

[0027] 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 one or more pins 410 can be used to pierce or rest on the anterior surface of the intraocular lens. In addition to capturing / confining the haptics 404a-404b by the anterior apex, the pins 410 are useful for further holding the intraocular pseudophakic contact lens 400 in place and preventing the intraocular pseudophakic contact lens 400 from slipping. In some cases, the pins 410 can be used to prevent the intraocular pseudophakic contact lens 400 from moving during the period immediately after implantation and before the haptics 404a-404b of the intraocular pseudophakic contact lens 400 adhere (e.g., due to fibrosis) to the anterior apex of the capsular wall of the patient's eye.

[0028] Each pin 410 may be formed from any suitable material and in any suitable manner. Although two pins 410 are shown here, the intraocular pseudophakic contact lens 400 may include any number of pins, including a single pin. It should also be noted that while the pins 410 are shown here as having sharp ends, this need not be the case. For example, the pins 410 may have rounded or blunt surfaces so that the pins 410 can rest (without puncturing) on ​​the anterior surface of the intraocular lens. Furthermore, while the pins 410 are shown here extending through or embedded within the extensions 406, they may be located in other suitable locations. For example, the pins 410 may be moved to the outer ends of the haptics 404a-404b, or additional pins 410 may be located at the outer ends of the haptics 404a-404b.

[0029] As mentioned above, implantation of the intraocular pseudophakic contact lens 400 can occur during the same procedure as implantation of the intraocular lens, or during a subsequent procedure after the intraocular lens has already been implanted in the patient's eye. The anterior apex of the capsular bag wall of the patient's eye can trap and confine the haptics 404a-404b of the intraocular pseudophakic contact lens 400 below the anterior apex, and can optionally fibrosis and refibrosis to attach the haptics 404a-404b to the patient's eye. The pins 410 can be used to hold the intraocular pseudophakic contact lens 400 in place.

[0030] 6 to 8 show a third example of an intraocular pseudophakic contact lens 600 according to the present disclosure. Specifically, Fig. 6 shows a perspective view of the intraocular pseudophakic contact lens 600, Fig. 7 shows a top view of the intraocular pseudophakic contact lens 600, and Fig. 8 shows a side view of the intraocular pseudophakic contact lens 600.

[0031] As shown in FIGS. 6-8, the intraocular pseudophakic contact lens 600 includes an optical lens 602 that is the same as or similar to the optical lenses 202, 402 described above. The intraocular pseudophakic contact lens 600 also includes a plurality of haptics 604a-604b and, optionally, a plurality of extensions 606. Here, the haptics 604a-604b are formed by loops of material such as metal or plastic. The ends of the haptics 604a-604b are embedded within the extensions 606 in this example, but the extensions 606 may be omitted and the haptics 604a-604b may be coupled to the optical lens 602 or a retaining ring in which the optical lens 602 is disposed. It is noted that the haptics 604a-604b are angled downward, but may have other suitable arrangements. Each haptic 604a-604b may have a textured surface that promotes containment, capture, and attachment to the anterior apex of the capsular bag wall.

[0032] Implantation of the intraocular pseudophakic contact lens 600 can occur during the same procedure as implantation of the intraocular lens, or during a subsequent procedure after the intraocular lens has already been implanted in the patient's eye. The anterior apex of the capsular bag wall of the patient's eye can trap and confine the haptics 604a-604b of the intraocular pseudophakic contact lens 600 below the anterior apex, and can optionally cause fibrosis and refibrosis to attach the haptics 604a-604b to the patient's eye.

[0033] 9 and 10 show a fourth example of an intraocular pseudophakic contact lens 900 according to the present disclosure. Specifically, Fig. 9 shows a perspective view of the intraocular pseudophakic contact lens 900, and Fig. 10 shows a side view of the intraocular pseudophakic contact lens 900.

[0034] As shown in Figures 9-10, the intraocular pseudophakic contact lens 900 has various components that are the same or similar to those that form the intraocular pseudophakic contact lens 600. For example, the intraocular pseudophakic contact lens 900 includes an optical lens 902, a number of haptics 904a-b, and, optionally, a number of extensions 906. The haptics 904a-b extend a short distance from the optical lens 902 to form small loops sized and shaped to fit beneath the anterior apex of the capsular bag wall of the patient's eye after implantation. Each haptic 904a-b may have a textured surface that promotes containment, capture, and attachment to the anterior apex of the capsular bag wall.

[0035] 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 one or more pins 908 can be used to pierce or rest on the anterior surface of the intraocular lens. In addition to capturing / confining the haptics 904a-904b by the anterior apex, the pins 908 are useful for further holding the intraocular pseudophakic contact lens 900 in place and preventing the intraocular pseudophakic contact lens 900 from slipping. In some cases, the pins 908 can be used to prevent the intraocular pseudophakic contact lens 900 from moving during the period immediately after implantation and before the haptics 904a-904b of the intraocular pseudophakic contact lens 900 adhere (e.g., due to fibrosis) to the anterior apex of the capsular bag wall of the patient's eye.

[0036] Each pin 908 may be formed from any suitable material and in any suitable manner. Although two pins 908 are shown, the intraocular pseudophakic contact lens 900 may include any number of pins, including a single pin. It should also 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 may have rounded or blunt surfaces so that the pins 908 can rest (without puncturing) on ​​the anterior surface of the intraocular lens. Furthermore, although the pins 908 are shown here as extending through or embedded within the extensions 906, they may be located in other suitable locations. For example, the pins 908 may be moved to the outer ends of the haptics 904a-904b, or additional pins 908 may be located at the outer ends of the haptics 904a-904b.

[0037] Implantation of the intraocular pseudophakic contact lens 900 can occur during the same procedure as implantation of the intraocular lens, or during a subsequent procedure after the intraocular lens has already been implanted in the patient's eye. The anterior apex of the capsular bag wall of the patient's eye can trap and confine the haptics 904a-904b of the intraocular pseudophakic contact lens 900 below the anterior apex, and can optionally fibrosis and refibrosis to attach the haptics 904a-904b to the patient's eye. Pins 908 can be used to hold the intraocular pseudophakic contact lens 900 in place.

[0038] 11 and 12 show a fifth example of an intraocular pseudophakic contact lens 1100 according to the present disclosure. Specifically, Fig. 11 shows a perspective view of the intraocular pseudophakic contact lens 1100, and Fig. 12 shows a side view of the intraocular pseudophakic contact lens 1100.

[0039] As shown in Figures 11-12, the intraocular pseudophakic contact lens 1100 includes various components that are the same or similar to those that form the intraocular pseudophakic contact lens 900. For example, the intraocular pseudophakic contact lens 1100 includes an optical lens 1102, a number of haptics 1104a-b, and, optionally, a number of extensions 1106. The haptics 1104a-b extend a short distance from the optical lens 1102 to form small loops sized and shaped to fit beneath the anterior apex of the capsular bag wall of the patient's eye after implantation. Each haptic 1104a-b may have a textured surface that promotes containment, capture, and attachment to the anterior apex of the capsular bag wall.

[0040] The intraocular pseudophakic contact lens 1100 also includes one or more pins 1108. Each pin 1108 projects downwardly from the outer end of the haptics 1104a-b. Thus, the pins 1108 are positioned farther from the optical lens 1102 than the pins 908. This allows the intraocular pseudophakic contact lens 1100 to be used with larger intraocular lenses. It also allows the pins 1108 to extend to or beyond the edge of the intraocular lens, which is useful for securing the intraocular pseudophakic contact lens 1100 to the front or side of the intraocular lens, and for reducing slippage of the intraocular pseudophakic contact lens on the intraocular lens.

[0041] Implantation of the intraocular pseudophakic contact lens 1100 can occur during the same procedure as implantation of the intraocular lens, or during a subsequent procedure after the intraocular lens has already been implanted in the patient's eye. The anterior apex of the capsular bag wall of the patient's eye can trap and confine the haptics 1104a-1104b of the intraocular pseudophakic contact lens 1100 below the anterior apex, and can optionally fibrosis and refibrosis to attach the haptics 1104a-1104b to the patient's eye. Pins 1108 can be used to hold the intraocular pseudophakic contact lens 1100 in place.

[0042] Fig. 13 illustrates a sixth example intraocular pseudophakic contact lens 1300 according to the present disclosure. As illustrated in Fig. 13, the intraocular pseudophakic contact lens 1300 includes an optical lens 1302 and a plurality of haptics 1304a-1304c. The optical lens 1302 may be the same as or similar to the various optical lenses described above.

[0043] In this example, the haptics 1304a-c are formed by large protrusions extending from the sides of the optical lens 1302, with the protrusions having a thickness that tapers toward their outer edges. This allows for easy insertion of the haptics 1304a-c beneath the anterior apex of the capsular bag wall of the patient's eye. Each haptic 1304a-c may have a textured surface, such as a number of holes or other structures that facilitate containment, capture, or attachment to the anterior apex of the capsular bag wall. Although three haptics 1304a-c are shown here, other numbers of haptics are possible.

[0044] 14 and 15 show a seventh example of an intraocular pseudophakic contact lens 1400 according to the present disclosure. Specifically, Fig. 14 shows a perspective view of the intraocular pseudophakic contact lens 1400, and Fig. 15 shows a cross-sectional view passing through the center of the intraocular pseudophakic contact lens 1400.

[0045] 14-15, an intraocular pseudophakic contact lens 1400 includes an optical lens 1402 and a number of haptics 1404a-b. The optical lens 1402 may be the same as or similar to the various optical lenses described above. Each of the haptics 1404a-b may have a textured surface, such as a number of holes or other structures that facilitate containment, capture, or attachment to the anterior apex of the capsular bag wall.

[0046] In this example, the haptics 1404a-b are formed by larger protrusions extending from the sides of the optical lens 1402. Each haptic 1404a-b has an inner portion 1406 connected to the optical lens 1402 and an outer portion 1408 connected to the inner portion 1406, effectively forming a long "wing" extending from the optical lens 1402. The outer portion 1408 has a thickness that tapers toward the outer edge of the haptics 1404a-b. This allows for easy insertion of the haptics 1404a-b below the anterior apex of the capsular bag wall of the patient's eye. In this example (although other configurations are possible), the inner portion 1406 protrudes outward and downward, while the outer portion 1408 protrudes outward and slightly upward. This shape allows for use with larger intraocular lenses while still allowing haptics 1404a-1404b to extend below the anterior apex of the capsular bag wall.

[0047] Each haptic 1404a-b also includes a ridge 1410 that can capture one or more edges of an underlying intraocular lens by the ridges 1410 of the haptics 1404a-b, thereby allowing the intraocular pseudophakic contact lens 1400 to be centered on the intraocular lens and holding the intraocular pseudophakic contact lens 1400 in place on the intraocular lens during the healing process.

[0048] Figures 16 to 18 show an eighth example of an intraocular pseudophakic contact lens 1600 according to the present disclosure. Specifically, Figure 16 shows a perspective view of the intraocular pseudophakic contact lens 1600, Figure 17 shows a top view of the intraocular pseudophakic contact lens 1600, and Figure 18 shows a cross-sectional view passing through the center of the intraocular pseudophakic contact lens 1600.

[0049] As shown in FIGS. 16-18, the intraocular pseudophakic contact lens 1600 includes various components that are the same or similar to those that form the intraocular pseudophakic contact lens 1400. For example, the intraocular pseudophakic contact lens 1600 includes an optical lens 1602 and a number of haptics 1604a-b. The haptics 1604a-b are formed by larger protrusions extending from the sides of the optical lens 1602. Each haptic 1604a-b has an inner portion 1606 connected to the optical lens 1602 (or a retaining ring in which the optical lens 1602 is disposed) and an outer portion 1608 connected to the inner portion 1606. The outer portion 1608 has a thickness that tapers toward the outer edge of the haptics 1604a-b. This allows for easy insertion of the haptics 1604a-b beneath the anterior apex of the capsular bag wall of the patient's eye. In this example, both inner portion 1606 and outer portion 1608 project outwardly and straight (although other configurations are possible), allowing for use with larger intraocular lenses while still allowing haptics 1604a-b to extend below the anterior apex of the capsular bag wall.

[0050] Each haptic 1604a-b also includes a ridge 1610 that can capture one or more edges of the underlying intraocular lens, thereby allowing the intraocular pseudophakic contact lens 1600 to be centered on the intraocular lens and holding the intraocular pseudophakic contact lens 1600 in place on the intraocular lens during the healing process.

[0051] The intraocular pseudophakic contact lens 1600 now also includes a number of segments 1612 located along the sides of the optical lens 1602. These segments 1612 are protrusions from the optical lens 1602, and at least some of the segments 1612 may be connected to the haptics 1604a-b (such as when the ends of the haptics 1604a-b are embedded in the segments 1612). The segments 1612 extend downward such that the bottom surfaces of the segments 1612 are located below the optical lens 1602. As a result, when implanted in a patient's eye, the segments 1612 keep the optical lens 1602 separated from the underlying intraocular lens. Depending on the shape of the posterior surface of the optical lens 1602 and the anterior surface of the underlying intraocular lens, the optical lens 1602 can be elevated above the optical lens in the underlying intraocular lens such that the optical lenses do not contact each other.

[0052] Each segment 1612 may be formed from any suitable material and in any suitable manner. For example, each segment 1612 may be a portion of the material forming the optical lens 1602, and thus an extension of the optical lens 1602 itself, but this is not necessarily the case. For example, the optical lens 1602 may be disposed in a retaining ring that is integral with or attached to the segment 1612, or may be secured to the optical lens 1602 itself using an adhesive or other suitable connection mechanism. Each segment 1612 may have any suitable size, shape, and dimensions. For example, the segment 1612 may be smaller or larger (relative to other structures) than those shown in Figures 16-18. As another example, the segment 1612 may be a curved structure that leaves a small open area between the segment 1612 and the optical lens 1602, or may be a solid structure that leaves no open area between the segment 1612 and the optical lens 1602.

[0053] The ability to space the optic 1602 away from the underlying intraocular lens may provide a variety of benefits. For example, raising the optic 1602 above the underlying intraocular lens may increase the amount of water that can flow between the anterior surface of the intraocular lens and the posterior surface of the optic 1602. Increasing water flow between the lenses reduces the amount of lens deposits on one or both of the lenses. The presence of water between the lenses may also improve the optics and image quality of a compound lens system. Additionally, providing more space between the lenses allows the intraocular pseudophakic contact lens 1600 to be used with a wider range of intraocular lenses with varying anterior curvatures, allowing the intraocular pseudophakic contact lens 1600 to be used with a wider range of intraocular lens models and powers.

[0054] Figures 19-21 show a ninth example of an intraocular pseudophakic contact lens 1900 according to the present disclosure. Specifically, Figure 19 shows a perspective view of the intraocular pseudophakic contact lens 1900, Figure 20 shows a top view of the intraocular pseudophakic contact lens 1900, and Figure 21 shows a cross-sectional view through the center of the intraocular pseudophakic contact lens 1900.

[0055] As shown in Figures 19-21, the intraocular pseudophakic contact lens 1900 has various components that are the same or similar to those that form the intraocular pseudophakic contact lens 1600. For example, the intraocular pseudophakic contact lens 1900 includes an optical lens 1902 and a number of haptics 1904a-b. The haptics 1904a-b are formed by larger protrusions extending from the sides of the optical lens 1902. Each haptic 1904a-b has an inner portion 1906 connected to the optical lens 1902 (or to a retaining ring in which the optical lens 1902 is disposed) and an outer portion 1908 connected to the inner portion 1906. Each haptic 1904a-b also includes a ridge 1910 that can 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 optic 1902. These segments 1912 extend downwardly such that their bottom surfaces are located below optic 1902.

[0056] The haptics 1904a-1904b of this example have thicker outer portions 1908 with larger ridges 1910 as compared to the corresponding components of the intraocular pseudophakic contact lens 1600. This allows the haptics 1904a-1904b to be used with even larger intraocular lenses. Additionally, each ridge 1910 has a lip 1911 that can facilitate capture of the underlying intraocular lens. Each lip 1911 may be any suitable inward protrusion from the corresponding ridge 1910.

[0057] Again, once implanted in a patient's eye, the segment 1912 helps to keep the optic 1902 separated from the underlying intraocular lens. Depending on the shape of the posterior surface of the optic 1902 and the anterior surface of the underlying intraocular lens, the optic 1902 can be elevated above the optic in the underlying intraocular lens such that the optics do not contact one another. The ability to space the optic 1902 away from the underlying intraocular lens can provide various advantages, as discussed above with respect to the intraocular pseudophakic contact lens 1600.

[0058] Various conventional approaches have secured an "add-on" lens to an intraocular lens, but these conventional approaches require that a specific add-on lens be designed for use with a specific intraocular lens, or vice versa. That is, an add-on lens can only be used with a specific type of intraocular lens, which is specifically designed for use with that add-on lens. As a specific example, an add-on lens may include haptics or other structures designed to mate with corresponding structures on a specific intraocular lens, or the intraocular lens may have a recess designed to accommodate a specific type of add-on lens. This is problematic for a number of reasons. For example, many patients already have existing intraocular lenses, making it impractical or dangerous to attempt to remove those existing intraocular lenses in order to implant a new intraocular lens designed for use with the add-on lens.

[0059] The intraocular pseudophakic contact lens embodiments shown in Figures 1-21 can alleviate these problems by allowing the intraocular pseudophakic contact lens to be secured onto the intraocular lens by capturing and entrapping the haptics of the intraocular pseudophakic contact lens with the anterior apex of the capsular wall. In some cases, the haptics may be physically bonded to the anterior apex of the capsular wall, such as through a fibrosis or refibrosis mechanism. In other words, the intraocular pseudophakic contact lens does not need to be designed to function specifically with the specific structure of a particular intraocular lens. The intraocular lens used with the intraocular pseudophakic contact lens need not have a predefined structure provided for bonding with the intraocular pseudophakic contact lens. Rather, the intraocular pseudophakic contact lenses of Figures 1-21 can simply be sized such that when the intraocular pseudophakic contact lens is placed onto the intraocular lens, it can be secured in place by being captured and entrapped by (and possibly bonded with) the anterior apex of the capsular wall. This allows the intraocular pseudophakic contact lenses of Figures 1-21 to be used with a wide variety of intraocular lenses, including different types of intraocular lenses and existing intraocular lenses already implanted in the patient. There is no need to remove the existing intraocular lens from the patient in order to install a new intraocular lens and intraocular pseudophakic contact lens.

[0060] 1-21 can also be easily removed from a patient's eye, such as at any suitable time after implantation or before the haptics bond to the capsular bag wall (assuming fibrosis and refibrosis holds the intraocular pseudophakic contact lens in place). This allows, among other things, one intraocular pseudophakic contact lens to be removed and replaced with a different intraocular pseudophakic contact lens if a different refractive correction is needed or desired.

[0061] The various intraocular pseudophakic contact lenses described above may have any suitable size, shape, and dimensions. For example, intraocular pseudophakic contact lenses are available in diameters ranging from about 4 mm to about 6 mm. Intraocular pseudophakic contact lenses are also available with varying base curvatures of the optical lens. Of course, intraocular pseudophakic contact lenses can also be custom designed for a particular patient's eye, such as when one or more specific curvatures are required to correct the residual refractive error of a particular patient's eye.

[0062] The intraocular pseudophakic contact lens disclosed herein can be non-invasively implanted in a patient's eye and easily positioned over the intraocular lens. Implantation is non-invasive because the intraocular pseudophakic contact lens is placed in front of the intraocular lens and is typically easily accessible by the surgeon or other personnel during the implantation procedure. Implantation is also non-invasive because the intraocular pseudophakic contact lens can be attached to the intraocular lens without the need to attach the intraocular pseudophakic contact lens to an anatomical structure within the patient's eye, such as the sulcus of the patient's eye.

[0063] The non-invasive implantation and easy positioning of intraocular pseudophakic contact lenses allows for safe and effective refractive surgery to correct unwanted residual refractive errors, such as after lensectomy. As a refractive modality, intraocular pseudophakic contact lenses contribute to the surgeon's ability to improve the current refractive error of pseudophakic patients in order to adjust the patient's vision to achieve a fine-tuned desired refraction. Specific examples of this functionality include allowing adjustment of the patient's eyes to achieve unilateral or bilateral emmetropia, inducing unilateral myopia to allow intermediate and near vision function, introducing multifocality, and treating unwanted residual astigmatism.

[0064] If the haptics of the intraocular pseudophakic contact lens include a ridge along its bottom surface, the ridge can center the intraocular pseudophakic contact lens over the underlying intraocular lens as described above. If the intraocular pseudophakic contact lens includes three haptics with associated ridges, the ridges can perfectly center the intraocular pseudophakic contact lens over the underlying intraocular lens. In this manner, the ridges of the haptics of the intraocular pseudophakic contact lens can capture the underlying intraocular lens at its edge, perfectly aligning the optical center of the intraocular pseudophakic contact lens with the optical center of the intraocular lens. This alignment can be useful in reducing or avoiding induced optical aberrations and induced prisms caused by misalignment of the optical centers. This provides a powerful contribution advantage over traditional refractive fine-tuning modalities.

[0065] It should be noted that in any of the above examples, the intraocular pseudophakic contact lens may be designed such that only the haptics of the intraocular pseudophakic contact lens extend below the anterior apex of the capsular bag wall of the patient's eye, thereby allowing the haptics to be captured and trapped at the anterior apex while leaving the optic of the intraocular pseudophakic contact lens free to remain generally invisible to the surrounding tissues of the patient's eye.

[0066] Although FIGS. 1-21 show examples of intraocular pseudophakic contact lenses, various modifications can be made to FIGS. 1-21. For example, any suitable combination of features shown in FIGS. 1-21 can be used together in a single intraocular pseudophakic lens, regardless of whether a particular combination of features is shown in the figures or described above. As a specific example, any of the intraocular pseudophakic contact lenses shown in FIGS. 1-21 can include one or more pins in one or more desired locations, one or more ridges along the bottom surface of one or more haptics for capture and centering of the intraocular lens on the intraocular lens, and / or one or more lips to aid in capture of the intraocular lens. Additionally, each intraocular pseudophakic contact lens can include any suitable number of each component shown in any of the figures. Although the intraocular pseudophakic contact lenses are shown in the figures as having two or three haptics evenly spaced at 120° or 180°, any number of haptics (with or without associated pins, ridges, lips, or other structures) can be used. Additionally, the haptic configurations shown herein are exemplary only, and other suitable structures may be used to capture, confine, or attach to the anterior apex of the capsular bag wall of the patient's eye. Additionally, many other features may be used at one or more locations on the intraocular pseudophakic contact lens. For example, one or more alignment markings may be provided to identify proper alignment of the intraocular pseudophakic contact lens with the intraocular lens. Additionally, one or more drug eluting materials may be disposed on the top, side, or bottom surface of the optic of the intraocular pseudophakic contact lens.

[0067] FIG 22 illustrates an example of an intraocular lens and an example of an intraocular pseudophakic contact lens in a patient's eye 2200 according to the present disclosure. As shown in FIG 22, eye 2200 has a cornea 2202, a sclera 2204, and an iris 2206. The cornea 2202 is the clear front part of the eye 2200 through which light passes to enter the eye 2200. The sclera 2204 is the tough white part of the eye. The iris 2206 controls the amount of light that passes from the cornea 2202 into the eye 2200 by controlling the size of the eye's pupil.

[0068] The eye 2200 also typically includes a capsular bag 2208 that holds the natural lens of the eye 2200. However, in this example, the natural lens has been removed and replaced with an intraocular lens 2210 having an optical lens 2212 and one or more haptics 2214. The optical lens 2212 of the intraocular lens 2210 receives light that enters the eye and focuses the light onto the retina of the eye 2200. The haptics 2214 of the intraocular lens 2210 serve to hold the intraocular lens 2210 within the capsular bag 2208 such that the optical lens 2212 of the intraocular lens 2210 is in a desired position within the eye.

[0069] An intraocular pseudophakic contact lens 2216 is also placed on the intraocular lens 2210 in the capsule 2208. The intraocular pseudophakic contact lens 2216 can be any of the intraocular pseudophakic contact lenses described above or other suitable intraocular pseudophakic contact lenses. The intraocular pseudophakic contact lens 2216 is placed on the front surface of the intraocular lens 2210, which refers to the front surface of the intraocular lens 2210 relative to the eye 2200. Light enters through the cornea 2202 and passes through the pupil, which modifies the light, before entering the intraocular pseudophakic contact lens 2216. The modified light then passes through the optical lens 2212 of the intraocular lens 2210 and is modified again. The twice modified light then passes through the rest of the eye 2200 to reach the retina at the back of the eye 2200.

[0070] As described above, the intraocular pseudophakic contact lens 2216 includes one or more haptics that extend a short distance and fit under the anterior cusp 2218 of the capsular bag 2208. This allows the haptics to be captured and confined by (and attached to) the anterior cusp 2218 by fibrosis and refibrosis, if necessary. The anterior cusp 2218 is the outer portion of the anterior surface of the capsular bag 2208 that remains after a capsule has formed within the capsular bag 2208. The haptics of the intraocular pseudophakic contact lens 2216 can be inserted under the anterior cusp 2218 to fix the intraocular pseudophakic contact lens 2216 in place. In some cases, the healing process of the eye 2200 may cause fibrosis, which may allow the anterior cusp 2218 to attach to the haptics of the intraocular pseudophakic contact lens 2216.

[0071] It should be noted that the haptics of the intraocular pseudophakic contact lens 2216 are shorter or smaller than the haptics 2214 of the intraocular lens 2210 because the haptics 2214 of the intraocular lens 2210 extend approximately to the top and bottom of the capsule 2208 and can hold the intraocular lens 2210 in the proper position within the capsule 2208. The haptics of the intraocular pseudophakic contact lens 2216 do not have to extend to the top and bottom of the capsule 2208, but only need to extend a short distance below the anterior cusp 2218.

[0072] By appropriately selecting the optics of the intraocular pseudophakic contact lens 2216, the intraocular pseudophakic contact lens 2216 can ideally correct any residual refractive error remaining after implantation of the intraocular lens 2210. The intraocular pseudophakic contact lens 2216 can also be removed and replaced with another intraocular pseudophakic contact lens, if necessary. This may be necessary or desirable in cases where the intraocular pseudophakic contact lens 2216 does not adequately correct the residual refractive error, or where the intraocular pseudophakic contact lens 2216 actually introduces additional refractive error.

[0073] Although Figure 22 illustrates an example intraocular lens in a patient's eye and an example pseudophakic intraocular contact lens, various modifications can be made to Figure 22. For example, intraocular lens 2210 can be attached to other pseudophakic intraocular contact lenses. Also, many intraocular lenses are available and the intraocular pseudophakic contact lens can be coupled to other suitable intraocular lenses in eye 2200.

[0074] FIG. 23 illustrates an example method 2300 of using an intraocular pseudophakic contact lens with an intraocular lens according to the present disclosure. As shown in FIG. 23, step 2302 involves identifying residual refractive error in a patient's eye having an intraocular lens. This may include, for example, having a practitioner test the patient's visual acuity to identify any refractive error remaining after implantation of the intraocular lens 2210. This testing may be performed in any suitable manner, such as using intraoperative wavefront aberrometry. One purpose of this testing is to identify what refractive error is present in the patient's eye after implantation of the intraocular lens in the patient's eye. This testing may be performed at any suitable time, such as after a lensectomy.

[0075] In step 2304, an intraocular pseudophakic contact lens (IOPCL) is selected to (ideally) correct the identified residual refractive error. This may include, for example, the practitioner selecting an intraocular pseudophakic contact lens from a kit, the selected intraocular pseudophakic contact lens having an optical lens that approximately offsets the identified residual refractive error. It may also include the practitioner selecting an optical lens from the kit and inserting the optical lens into the intraocular pseudophakic contact lens, the selected optical lens approximately offsetting the identified residual refractive error. It may also include the practitioner obtaining an intraocular pseudophakic contact lens having a custom-designed optical lens or obtaining a custom-designed optical lens for insertion into the intraocular pseudophakic contact lens. The custom-designed optical lens approximately offsets the identified residual refractive error. In general, any mechanism may be used to obtain a suitable intraocular pseudophakic contact lens.

[0076] In step 2306, the selected intraocular pseudophakic contact lens is inserted into the patient's eye, which may include, for example, having a surgeon or practitioner make a small incision in the patient's eye and insert the intraocular pseudophakic contact lens into the eye through the incision. The intraocular pseudophakic contact lens may be rolled, folded, or otherwise reduced in cross-sectional size for insertion through a smaller incision.

[0077] In step 2308, one or more haptics of an intraocular pseudophakic contact lens are inserted under the anterior apex of the capsular bag wall of the patient's eye. This may involve, for example, positioning the intraocular pseudophakic contact lens 2216 by a surgeon or other practitioner in a desired position (and possibly a desired orientation) on the intraocular lens 2210. This may also involve moving the intraocular pseudophakic contact lens 2216 by the surgeon or other practitioner so that its haptics (whatever shape) slide under the anterior apex 2218 of the capsular bag 2208.

[0078] In step 2310, the patient's visual acuity is tested. This visual acuity test can be performed in any suitable manner, such as using intraoperative wavefront aberrometry. This visual acuity test can also be performed at any suitable time, such as during the surgical procedure when the intraocular pseudophakic contact lens is implanted, or after the surgical procedure is completed. In step 2312, a determination is made as to whether the visual acuity obtained during the test is satisfactory, for example, by determining whether the patient's eye is still experiencing residual refractive error.

[0079] In step 2314, a decision is made to change the intraocular pseudophakic contact lens. This includes, for example, by the practitioner and the patient, determining whether the remaining residual refractive error (if any) is inconvenient or problematic for the patient. If there is a problem, various procedures can be performed to resolve the problem. For example, the currently implanted intraocular pseudophakic contact lens can be repositioned to adjust the cylinder axis correction. If that fails, in step 2316, a different intraocular pseudophakic contact lens is selected. This includes, for example, by the practitioner selecting a different intraocular pseudophakic contact lens that provides better refractive correction to the patient's eye compared to the currently inserted intraocular pseudophakic. In step 2318, the currently inserted intraocular pseudophakic contact lens is removed from the patient's eye. This includes, for example, by the surgeon or other practitioner removing the currently inserted intraocular pseudophakic contact lens 2216 from the patient's eye by sliding the haptics of the currently inserted intraocular pseudophakic contact lens 2216 from under the anterior cusp 2218. The method then returns to step 2306, where a newly selected intraocular pseudophakic contact lens may be inserted into the patient's eye and the vision test repeated.

[0080] 23 is completed, the haptics of the implanted intraocular pseudophakic contact lens 2216 may be captured / trapped by the anterior apex 2218 of the capsular bag 2208 of the patient's eye. This helps to hold the intraocular pseudophakic contact lens 2216 in place. Additionally, the healing process of the patient's eye may optionally cause fibrosis or re-fibrosis, which may cause the haptics of the implanted intraocular pseudophakic contact lens 2216 to become physically attached to the anterior apex 2218 of the capsular bag 2208.

[0081] While Figure 23 illustrates one example of a method 2300 for using an intraocular pseudophakic contact lens with an intraocular lens, various modifications may be made to Figure 23. Processes may overlap, occur in parallel, occur in different orders, or occur any number of times.
