Description

[Technical Field]

[0001] The present disclosure relates generally to implantable optical devices, and more particularly to intraocular pseudophakic contact lenses and related systems and methods. [Background technology]

[0002] In a healthy eye, light rays that enter the cornea pass through the pupil, and the natural lens focuses the light rays onto the retina of the eye. However, cataracts and other disorders can make it necessary to replace the natural lens of the eye with an artificial intraocular lens (IOL). The term "pseudophakic" is used to describe eyes 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 professional typically selects an intraocular lens designed to provide the desired refractive correction for the patient's eye. For example, the intraocular lens may be equipped with an optical lens designed to correct myopia (nearsightedness), hyperopia (farsightedness), astigmatism, or other refractive errors naturally occurring in the patient's eye. However, it is often the case that the intraocular lens selected for a patient's eye ends up not adequately correcting (and may even cause) certain refractive errors in the patient's eye. This refractive error is referred to as "residual" refractive error. Summary of the Invention [Problem to be solved by the invention]

[0004] While various options for correcting residual refractive error have been available, each has its drawbacks. For example, while a patient's existing intraocular lens can be replaced with another, this procedure generally carries a significant risk of surgical complications. To correct residual refractive error, a corneal ablation procedure (e.g., LASIK) may be performed on the patient's eye, but this procedure can result in serious undesirable side effects, especially in elderly patients. While an additional intraocular lens (often referred to as a "piggyback" IOL) could be implanted in front of the existing intraocular lens, this procedure is generally invasive, making the final refractive power difficult to predict. Additionally, an intracorneal lens (ICL) can be implanted into the cornea of ​​the patient's eye, but this procedure is often highly invasive and can have a high rate of rejection. Overall, the above-mentioned procedures generally involve unpredictable outcomes and significant surgical risks. Furthermore, the devices used in the above-mentioned techniques are unlikely to eliminate or "reverse" residual refractive error, resulting in a high risk of leaving patients with induced visual defects behind. [Means for solving the problem]

[0005] FIELD OF THE DISCLOSURE The present disclosure relates to intraocular pseudophakic contact lenses and related systems and methods.

[0006] In a first embodiment, the device includes an intraocular pseudophakic contact lens including a first optic configured to at least partially correct residual refractive error of the eye and a plurality of anchors configured to be inserted through the anterior surface of the intraocular lens and into lens material forming the second optic of the intraocular lens to secure the intraocular pseudophakic contact lens to the intraocular lens.

[0007] In a second embodiment, a system includes an intraocular pseudophakic contact lens and an intraocular lens including a first lens optic configured to at least partially correct residual refractive error of an eye and a plurality of anchors. The intraocular lens includes a second lens optic formed from a lens material. The anchors are configured to be inserted into the lens material through an anterior surface of the intraocular lens to secure the intraocular pseudophakic contact lens to the intraocular lens.

[0008] In a third embodiment, the apparatus includes an intraocular pseudophakic contact lens including a first optical lens configured to at least partially correct a residual refractive error of an eye, the intraocular pseudophakic contact lens also including at least one drug-eluting device disposed on the first optical lens and configured to deliver at least one drug, the intraocular pseudophakic contact lens configured to be connected to an intraocular lens in the eye, the residual refractive error being at least partially attributable to the intraocular lens.

[0012] 1-25 and the various embodiments used to illustrate the inventive subject matter described herein are for illustrative purposes only and should not be construed as limiting the scope of the invention. Those skilled in the art will appreciate that the inventive subject matter may be implemented in any type of suitably arranged device or system.

[0013] The present disclosure provides various intraocular pseudophakic contact lenses (IOPCLs) that can be used in combination with an intraocular lens (IOL). Generally, an intraocular pseudophakic contact lens refers to a contact lens-type device that can be implanted in a patient's eye and is fitted in front of the intraocular lens in the patient's eye. The intraocular pseudophakic contact lenses substantially correct residual refractive error that exists after implantation of an intraocular lens, such as after lensectomy (cataract) surgery.

[0014] Unlike conventional techniques, intraocular pseudophakic contact lenses can be implanted with minimal surgical risk. Furthermore, intraocular pseudophakic contact lenses allow the patient to see immediately after implantation. Furthermore, intraocular pseudophakic contact lenses can be easily replaced if another lens is needed to correct residual refractive error, or even removed if necessary. Additionally, currently available techniques, such as intraoperative wavefront aberration, can be used to measure refractive power during the implantation of an intraocular pseudophakic contact lens, which helps immediately confirm the achievement of the desired refractive power.

[0015] 1 to 3 show a first example of an intraocular pseudophakic contact lens (IOPCL) 100 of the present disclosure. Specifically, Fig. 1 is a perspective view of the intraocular pseudophakic contact lens 100, Fig. 2 is a plan view of the intraocular pseudophakic contact lens 100, and Fig. 3 is a cross-sectional view of the intraocular pseudophakic contact lens 100 taken along line AA in Fig. 2.

[0016] As shown in Figures 1 to 3, the intraocular pseudophakic contact lens 100 includes an optical lens 102. The optical lens 102 is illustrated as part of the intraocular pseudophakic contact lens 100 and refracts light rays passing through the intraocular pseudophakic contact lens 100. The light rays passing through the optical lens 102 then pass through the fixed intraocular lens before reaching the retina of the patient's eye.

[0017] The optical lenses 102 can be formed from any suitable material, such as silicone or acrylic, and can be formed by any suitable method, such as using a mold or lathe-cut manufacturing process. Other lenses 102 can be designed and manufactured with a wide range of diopters, and each optical lens 102 can be configured to properly correct any refractive error. Types of refractive errors that can be corrected include myopia, hyperopia, and astigmatism.

[0018] In this example, the optical lens 102 has a convex top surface and a concave bottom surface. However, the optical lens 102 may have any other suitable shape depending on the type of refractive error (at least in part) to be corrected. By way of example, the optical lens 102 may be convex, concave, spherical, aspherical, toric, monofocal, or multifocal. The lens platform suitable for use as the optical lens 102 of the intraocular pseudophakic contact lens 100 may be selected depending on the desired refractive correction to be provided to the patient's eye. The optical lens 102 itself may also have various additional features, such as increased weight, tinting, photochromic coating, or inclusion of ultraviolet (UV) absorbers, to position the optical lens 102 in a desired orientation relative to the intraocular lens (e.g., to form a toric platform).

[0019] A plurality of protrusions 104a-104b extend from multiple locations on the optical lens 102. The protrusions 104a-104b are used to secure a plurality of anchors 106a-106b extending downwardly of the intraocular pseudophakic contact lens 100. Each of the protrusions 104a-104b can be formed from any suitable material and in any suitable manner. For example, the protrusions 104a-104b can be part of the body forming the optical lens 102, i.e., the optical lens 102 expands on its own. However, this is not necessarily the case. For example, the optical lens 102 can be integrally formed with the protrusions 104a-104b, or can be mounted within a retaining ring secured to the protrusions 104a-104b, or the protrusions 104a-104b can be attached to the optical lens 102 using an adhesive or other suitable adhesive means. Although two protrusions 104a-104b are shown in this example, the intraocular pseudophakic contact lens 100 may utilize any number of protrusions, including a single protrusion.

[0020] The anchors 106a-106b are used to secure the intraocular pseudophakic contact lens 100 to the intraocular lens. For example, after the intraocular pseudophakic contact lens 100 is inserted into a patient's eye, a surgeon or other personnel can place the prongs 104a-104b or other portions of the intraocular pseudophakic contact lens 100 onto the intraocular lens. In this manner, the anchors 106a-106b are introduced against the anterior (front) surface of the intraocular lens and help secure the intraocular pseudophakic contact lens 100 to the intraocular lens. Each of the anchors 106a-106b can have any structure suitable for securing an intraocular pseudophakic contact lens to an intraocular lens. In this example, the anchors 106a-106b are depicted as barbed or ribbed pins, although other types of anchors, such as screws, can also be used. Each of the anchors 106a-106b can be formed from any suitable material and in any suitable manner. It should be noted that although two anchors 106a-106b are shown in this example, the intraocular pseudophakic contact lens 100 may utilize any number of anchors, including a single anchor.

[0021] 1-3, the anchors 106a-106b may be permanently embedded in the protrusions 104a-104b of the intraocular pseudophakic contact lens 100. However, this is not necessarily required.

[0022] Figures 4 to 7 show an intraocular pseudophakic contact lens 400 according to a second example of the present disclosure. In particular, Figure 4 is a perspective view of the intraocular pseudophakic contact lens 400, and Figure 5 is a plan view of the intraocular pseudophakic contact lens 400. Furthermore, Figure 6 is a cross-sectional view of the intraocular pseudophakic contact lens 400 taken along line BB in Figure 5, and Figure 7 is a bottom view of the intraocular pseudophakic contact lens 400.

[0023] As shown in Figures 4-7, the intraocular pseudophakic contact lens 400 includes various elements that are the same as or similar to those that make up the intraocular pseudophakic contact lens 100. For example, the intraocular pseudophakic contact lens 400 includes an optical lens 402 and a plurality of protrusions 404a-404b. The intraocular pseudophakic contact lens 400 is also secured to the intraocular lens using a plurality of anchors 406a-406b. However, the intraocular pseudophakic contact lens 400 in this example includes holes 408a-408b formed through the protrusions 404a-404b, and the anchors 406a-406b are inserted into the holes 408a-408b.

[0024] The optical lens 402 can be formed from any suitable material, such as silicone or acrylic. The optical lens 402 can be formed by any suitable method, such as using a mold or lathe-cutting manufacturing process. Other lenses 402 can be designed and manufactured in a wide range of diopters, and each optical lens 402 can be configured to properly correct any refractive error. In this example, the optical lens 402 has a convex top surface and a concave bottom surface; however, the optical lens 402 can have any other suitable shape depending on the type of refractive error (at least in part) to be corrected. By way of example, the optical lens 402 can be convex, concave, spherical, aspherical, toric, monofocal, or multifocal. The lens platform suitable for use as the optical lens 402 of the intraocular pseudophakic contact lens 400 can be selected depending on the desired refractive correction to be provided to the patient's eye. Various other features may be added to the optical lens 402 as needed or desired, such as increasing the weight of the optical lens 402 to position it in a desired orientation relative to the intraocular lens (e.g., to form a toric platform), or by tinting the optical lens 402, making it photochromic, or incorporating ultraviolet (UV) absorbers.

[0025] Each of the protrusions 404a-404b can be formed from any suitable material and in any suitable manner. For example, the protrusions 404a-404b can be part of the body forming the optical lens 402, i.e., the optical lens 402 extends from itself. However, this is not necessarily the case. For example, the optical lens 402 can be integrally formed with the protrusions 404a-404b, or can be mounted within a retaining ring secured to the protrusions 404a-404b, or the protrusions 404a-404b can be attached to the optical lens 402 using an adhesive or other suitable attachment means.

[0026] Each of the anchors 406a-406b may comprise any structure suitable for securing an intraocular pseudophakic contact lens to an intraocular lens. In this example, the anchors 406a-406b are depicted as barbed or ribbed pins, although other types of anchors, such as screws, may also be used. Each of the anchors 406a-406b may be formed from any suitable material and in any suitable manner.

[0027] Each of the holes 408a-408b can be of any suitable size, shape, and dimensions. Additionally, each of the holes 408a-408b can be formed in any suitable manner. For example, in some embodiments, after the protrusions 404a-404b are formed, the holes 408a-408b can be drilled into the corresponding protrusions 404a-404b, such as by using a mechanical drill or a laser drill. In other embodiments, each of the protrusions 404a-404b can be drilled into the corresponding holes 408a-408b.

[0028] It should be noted that while two protrusions 404a-404b, two anchors 406a-406b, and two holes 408a-408b are shown herein, the intraocular pseudophakic contact lens 400 may include any number of protrusions, anchors, and holes. Also, while each of the protrusions 404a-404b is shown as including a single cylindrical hole 408a-408b, each of the protrusions 404a-404b may include one or more holes of any suitable shape.

[0029] After the intraocular pseudophakic contact lens 400 is inserted into the patient's eye, a surgeon or other personnel can place the intraocular pseudophakic contact lens 400 on the intraocular lens. Before, during, or after insertion of the intraocular pseudophakic contact lens 400, the surgeon or other personnel can insert anchors 406a-406b through holes 408a-408b in the intraocular pseudophakic contact lens 400. The surgeon or other personnel can place the anchors 406a-406b or other portions of the intraocular pseudophakic contact lens 400 on the intraocular lens. In this manner, the anchors 406a-406b are introduced through the anterior surface of the intraocular lens and help secure the intraocular pseudophakic contact lens 400 to the intraocular lens.

[0030] 8 illustrates a third example intraocular pseudophakic contact lens 800 of the present disclosure. In this embodiment, the intraocular pseudophakic contact lens 800 is structurally similar to the intraocular pseudophakic contact lens 400. The intraocular pseudophakic contact lens 800 includes an optical lens 802, protrusions 804a-804b, and holes 808a-808b configured to receive anchors. All disclosures above regarding the optical lens 402, protrusions 404a-404b, and holes 408a-408b apply to the corresponding elements in FIG. 8.

[0031] In this example, holes 808a-808b are angled at a larger angle compared to holes 408a-408b described above. The larger angle of inclination of holes 808a-808b may be needed or desired under certain conditions. For example, the larger angle of inclination of holes 808a-808b may be used to secure intraocular pseudophakic contact lens 800 near the edge of the intraocular lens when the anterior surface of the intraocular lens is more inclined.

[0032] While various prior art methods have secured an "add-on" lens to an intraocular lens, these prior art methods require a specific add-on lens designed for use with a specific intraocular lens. That is, these add-on lenses can only be used with a specific type of intraocular lens, and the intraocular lens is specifically designed for use with the add-on lens. Specifically, the add-on lens may include haptics or other structures designed to match the structure of a corresponding specific intraocular lens, or the intraocular lens may include a recess designed to accept a specific type of add-on lens. This approach is problematic for a number of reasons. For example, many patients already have an intraocular lens implanted, and attempting to remove the existing intraocular lens in order to implant a new intraocular lens designed for use with the add-on lens may be impractical or even dangerous.

[0033] The intraocular pseudophakic contact lenses 100, 400, 800 in the embodiments shown in Figures 1-8 help address these challenges because the anchors of the intraocular pseudophakic contact lenses of the present disclosure are introduced into the existing lens material forming the intraocular lens. In other words, the intraocular pseudophakic contact lenses 100, 400, 800 do not need to be specifically designed to function with the individual structure of any particular intraocular lens. Rather, the intraocular pseudophakic contact lenses 100, 400, 800 only need to be sized so that their anchors can be introduced into the lens material of the intraocular lens when the intraocular pseudophakic contact lens 100, 400, 800 is placed on the intraocular lens. This allows the intraocular pseudophakic contact lenses 100, 400, 800 to be used with a wide variety of intraocular lenses, including different types of intraocular lenses and existing intraocular lenses already implanted in patients. There is no need to remove the existing intraocular lens from the patient to fit the new intraocular lens and intraocular pseudophakic contact lens.

[0034] Additionally, the anchor of the intraocular pseudophakic contact lens 100, 400, 800 can be easily removed from the lens material of the intraocular lens to remove the intraocular pseudophakic contact lens 100, 400, 800 from the intraocular lens, best of all allowing for the insertion of another intraocular pseudophakic contact lens in place of the removed intraocular pseudophakic contact lens if a different refractive correction is needed or desired.

[0035] Figure 9 illustrates a fourth example of an intraocular pseudophakic contact lens 900 of the present disclosure. As shown in Figure 9, the intraocular pseudophakic contact lens 900 includes an optical lens 902, which may be the same as or similar to the optical lenses described above. The intraocular pseudophakic contact lens 900 also includes protrusions 904a-904b, which may be the same as or similar to the protrusions described above.

[0036] Unlike the intraocular pseudophakic contact lenses described above, the protrusions 904a-904b described herein are connected to haptic loops 906a-906b. The haptic loops 906a-906b are used to secure the intraocular pseudophakic contact lens 900 to a portion 908a-908b of the patient's lens capsule. The haptic loops 906a-906b can be formed from any suitable material and in any suitable manner. For example, the haptic loops 906a-906b can be formed from polyimide. The haptic loops 906a-906b can have any suitable size, shape, and dimensions. Specific examples include haptic loops 906a-906b that are approximately 2 mm to 4 mm long. If desired, the haptic loops 906a-906b can be angled downward (e.g., at an angle of approximately 3°) to facilitate anchoring to the anterior capsule wall.

[0037] While two prongs and two haptic loops are shown herein, it should be noted that the intraocular pseudophakic contact lens 900 can include any number of prongs and haptic loops. Also, although not shown, combinations of haptic loops and anchors can be utilized in the intraocular pseudophakic contact lens 900. For example, the prongs 904a-904b can be secured to the haptic loops 906a-906b, and anchors can be inserted or embedded into the prongs 904a-904b. As another example, one of the prongs can be secured to the haptic loops 906a-906b, and an anchor can be inserted or embedded into the other prong 904a-904b.

[0038] Also, while anchors and haptic loops are described above as securing the intraocular pseudophakic contact lens to the intraocular lens, it should be noted that any other suitable mechanism can be used to secure the intraocular pseudophakic contact lens to the intraocular lens. For example, the intraocular pseudophakic contact lens can include an optic (with or without protrusions), and the intraocular pseudophakic contact lens would be held in place on the intraocular lens via surface tension at the anterior surface of the intraocular lens.

[0039] The various intraocular pseudophakic contact lenses described above can be of any size, shape, and dimension. For example, intraocular pseudophakic contact lenses can range in diameter from about 4 mm to about 6 mm. Additionally, intraocular pseudophakic contact lenses are available with varying curvatures depending on their optics. Of course, intraocular pseudophakic contact lenses can also be specifically designed for a particular patient's eye if one or more specific curvatures are required to correct the residual refractive error of that patient's eye.

[0040] The intraocular pseudophakic contact lenses described herein can be non-invasively implanted into a patient's eye and easily placed over the intraocular lens. This implantation is non-invasive because the intraocular pseudophakic contact lens rests on the anterior surface of the intraocular lens, which is generally easily accessible by a surgeon or other personnel during the implantation procedure. This implantation is also non-invasive because some intraocular pseudophakic contact lenses can be fixed to the intraocular lens without requiring fixation of the intraocular pseudophakic contact lens to an internal anatomical structure of the patient's eye, such as the suculus.

[0041] The non-invasive implantation and ease of placement of intraocular pseudophakic contact lenses provides a safe and effective refractive surgical procedure for correcting undesirable residual refractive errors, such as those observed after lensectomy. As a refractive tool, intraocular pseudophakic contact lenses aid the surgeon in modifying the existing refractive error of pseudophakic patients, with the goal of fine-tuning to obtain the desired refraction and improve the patient's visual acuity. Examples of this function include allowing adjustment of the patient's eyes to achieve monocular or binocular emmetropia, induce monocular myopia to allow intermediate and near vision function, introduce multifocality, and treat undesirable residual astigmatism.

[0042] While Figures 1-9 depict examples of intraocular pseudophakic contact lenses, various modifications can be made to Figures 1-9. For example, regardless of whether a particular combination of features is described in the figures above, the combination of features shown in Figures 1-9 can be used in a single intraocular pseudophakic contact lens. Also, each intraocular pseudophakic contact lens can include any suitable number of each element shown in the figures. Additionally, while the anchors and haptic loops are shown as protruding from the optic, the anchors and haptic loops can rather be used directly on the optic (such as when the optic is larger than needed to correct residual refractive error).

[0043] 10-12 are diagrams illustrating an example of an intraocular lens (IOL) 1000 connected to an example of an intraocular pseudophakic contact lens 100 of the present disclosure. In particular, FIG. 10 is a perspective view of the system, FIG. 11 is a plan view of the system, and FIG. 12 is a cross-sectional view of the system taken along line CC in FIG. 11.

[0044] As shown in FIGS. 10 and 11 , the intraocular lens 1000 includes an optical lens 1002 and a plurality of haptics 1004a-1004b. The optical lens 1002 receives light rays entering the eye (including light rays passing through the intraocular pseudophakic contact lens 100) and focuses them onto the retina of the patient's eye. The haptics 1004a-1004b help support the optical lens 1002 at a desired position within the patient's eye. For example, the entire intraocular lens 1000 can be placed within the lens capsule of the patient's eye, and the haptics 1004a-1004b can contact the inner wall of the lens capsule to support the optical lens 1002 at a desired position.

[0045] 10-12, the intraocular pseudophakic contact lens 100 is placed on the intraocular lens 1000, and the anchors 106a-106b of the intraocular pseudophakic contact lens 100 are guided through the anterior surface of the intraocular lens 1000 and into the lens material 1006 of the optical lens 1002. As described above, this procedure secures the intraocular pseudophakic contact lens 100 relative to the intraocular lens 1000. Furthermore, this procedure can be performed without the need for an intraocular lens 1000 specifically designed for use with the intraocular pseudophakic contact lens 100, and can be performed without the need for an intraocular lens 1000 specifically designed for use with the intraocular lens 1000.

[0046] This procedure is effective under various conditions, such as when the patient's eye already has an intraocular lens 1000 implanted and removal is not possible without excessive surgical risk, or when removal is completely impossible (due to the presence of pseudophakic tissue for a long period of time). Additionally, if the selected intraocular pseudophakic contact lens 100 does not correct the residual refractive error or if the intraocular pseudophakic contact lens 100 introduces new refractive error, the anchors 106a-106b can be pulled out of the lens material 1006 to remove the intraocular pseudophakic contact lens 100 from the intraocular lens 1000. Another intraocular pseudophakic contact lens can then be placed over the intraocular lens 1000 using the same or a similar method.

[0047] 12, it is noted that the outer portion of the intraocular pseudophakic contact lens 100 is actually brought into contact with the lens material 1006. However, this is not necessarily the case. Furthermore, in FIG. 12, only the outer portion of the intraocular pseudophakic contact lens 100 is in contact with the lens material 1006, and the remainder of the lower surface of the optical lens 102 within the intraocular pseudophakic contact lens 100 is spaced from the lens material 1006. However, a greater portion (or substantially the entire surface) of the lower surface of the optical lens 102 within the intraocular pseudophakic contact lens 100 can be in contact with the lens material 1006.

[0048] While Figures 10-12 show an example intraocular lens connected to an example intraocular pseudophakic contact lens, various modifications can be made to Figures 10-12. For example, intraocular lens 1000 can be connected to any other intraocular pseudophakic contact lens, such as contact lens 400 or 800 described above. Also, numerous intraocular lenses are available, and intraocular lens 1000 is one particular intraocular lens. The intraocular pseudophakic contact lens can be connected to any other suitable intraocular lens.

[0049] 13 and 14 illustrate an example of an intraocular lens 1000 and an example of an intraocular pseudophakic contact lens 1300 of the present disclosure within a patient's eye. As shown in FIGS. 13 and 14, the eye 1300 includes a cornea 1302, a sclera 1304, and an iris 1306. The cornea 1302 is located at the front of the eye 1300 and transmits light rays entering the eye 1300. The sclera 1304 is the tough, outer white part of the eye. The iris 1306 adjusts the size of the eye's pupil, thereby regulating the amount of light rays that enter the eye 1300 from the cornea 1302.

[0050] The eye 1300 also generally includes a capsular bag 1308 that supports the eye's 1300's natural lens. However, in this example, the natural lens has been removed and replaced with the intraocular lens 1000. The haptics 1004a-1004b of the intraocular lens 1000 help support the intraocular lens 1000 within the capsular bag 1308 so that the optic 1002 of the intraocular lens 1000 can be placed in a desired position within the eye.

[0051] The intraocular pseudophakic contact lens 100 is placed on top of the intraocular lens 1000 in the capsular bag 1308. The intraocular pseudophakic contact lens 100 is placed on the anterior surface of the intraocular lens 1000, i.e., the front surface of the intraocular lens 1000 relative to the eye 1300. Before reaching the intraocular pseudophakic contact lens 100, where it is corrected, the light rays pass through the cornea 1302 and then through the pupil. The corrected light rays then pass through the optic 1002 of the intraocular lens 1000 and are corrected again. The twice-corrected light rays then pass through the rest of the eye 1300 to reach the retina at the back of the eye 1300.

[0052] By appropriately selecting the optical lens 102 of the intraocular pseudophakic contact lens 100, the intraocular pseudophakic contact lens 100 can adequately correct any residual refractive error that remains after implantation of the intraocular lens 1000. If the intraocular pseudophakic contact lens 100 does not adequately correct the residual refractive error or if the intraocular pseudophakic contact lens 100 introduces a new refractive error, the intraocular pseudophakic contact lens 100 can be removed and replaced with another intraocular pseudophakic contact lens, as needed.

[0053] 13 and 14 illustrate an example intraocular lens and an example intraocular pseudophakic contact lens in a patient's eye, various modifications can be made to Figures 13 and 14. For example, intraocular lens 1000 can be coupled with any other intraocular pseudophakic contact lens, such as contact lenses 400 or 800 described above. Also, numerous intraocular lenses are available, and the intraocular pseudophakic contact lens can be coupled with any other suitable intraocular lens in eye 1300. Additionally, the intraocular lens need not be placed within the capsular bag of the eye, in which case the intraocular pseudophakic contact lens would not be placed within the capsular bag either.

[0054] 15 shows an example of an anchor 1500 of the present disclosure for connecting an intraocular pseudophakic contact lens to an intraocular lens. For example, anchor 1500 can be used in combination with any of the intraocular pseudophakic contact lenses described above.

[0055] As shown in FIG. 15 , anchor 1500 includes a head 1502 and a shank 1504. Head 1502 is the top of anchor 1500 and is depicted as being larger than shank 1504, although this is not necessarily the case depending on how anchor 1500 is used (e.g., head 1502 may be embedded in a protrusion). Shank 1504 extends downward from head 1502 to a sharp tip 1506. Tip 1506 is designed to be inserted into the lens material of an intraocular lens. Shank 1504 also includes barbed or ribbed portions 1508 that are designed to be inserted into the lens material of an intraocular lens and that resist (but do not substantially prevent) removal of shank 1504 from the lens material of the intraocular lens. This structure assists in securing the intraocular pseudophakic contact lens to the lens material of the intraocular lens, while still allowing for removal of the intraocular pseudophakic contact lens from the patient's eye if necessary or desired.

[0056] While Figure 15 depicts one example of an anchor 1500 for securing an intraocular pseudophakic contact lens to an intraocular lens, various modifications can be made to Figure 15. For example, the anchor can be used without any large head, or without any barbed or ribbed portions, or any other anchor can be used to secure an intraocular pseudophakic contact lens to an intraocular lens.

[0057] 16-24 illustrate other configurations that may be used with the intraocular pseudophakic contact lenses of the present disclosure. Intraocular pseudophakic contact lenses, including any of the intraocular pseudophakic contact lenses described above, may be used in any suitable combination of these configurations, any suitable combination of these configurations, or any suitable combination of these configurations.

[0058] 16 is a plan view of an intraocular pseudophakic contact lens 1600 including an optic 1602 and protrusions 1604a-1604b, which may be the same as or similar to the corresponding elements described above. Although not shown, the intraocular pseudophakic contact lens 1600 also includes a plurality of holes configured to receive a plurality of anchors.

[0059] Additionally, the intraocular pseudophakic contact lens 1600 includes alignment markings 1606a-1606b. The alignment markings 1606a-1606b generally determine the desired or optimal location of the anchor once it has been threaded through the hole. For example, the optic 1602 and prongs 1604a-1604b can be substantially transparent so that the anchors inserted into the prongs 1604a-1604b and located underneath the intraocular pseudophakic contact lens 1600 can be viewed through the intraocular pseudophakic contact lens 1600. The alignment markings 1606a-1606b can be used by a surgeon or other personnel to help ensure that the anchors are inserted straight into the underlying lens material of the intraocular lens, without being inserted crookedly or even completely missing lens material. Additionally, these markers 1606a-1606b can be used to identify the refractive correction (cylinder) in toric applications to enable the surgeon or other personnel to position the optical lens 1602 on the desired axis.

[0060] 17 is a plan view of an intraocular pseudophakic contact lens 1700 including an optical lens 1702 and protrusions 1704a-1704b, which may be the same as or similar to the corresponding elements described above. Although protrusions 1704a-1704b are described as including holes configured to receive multiple anchors, this may not be required, such as when the tips of the anchors are embedded in protrusions 1704a-1704b.

[0061] The intraocular pseudophakic contact lens 1700 also includes a drug-eluting matrix 1706 formed on at least a portion of the optical lens 1702. In this example, the drug-eluting matrix 1706 is shown as a small compartment in the optical lens 1702 that is coated with at least one drug, preferably contained in a gel or other means that regulates the release of the drug. Once implanted, the drug-eluting matrix 1706 releases the drug toward the patient's eye.

[0062] Any suitable medication, such as, but not limited to, medications for treating glaucoma or uveitis, can be applied to the optical lens 1702. This application can be performed using any suitable application pattern and in any suitable manner. For example, the medication can be applied in a ring-shaped pattern, such as a ring having a thickness of about 0.5 mm and having an opening or "donut hole" in the center of the pattern. Other application methods that provide improved vision with optical benefits (such as increased depth of focus, cylinder effect, or improvement of undesirable aberrations), such as a "slit design" in the optical center of the optical lens 1702, can also be used.

[0063] 18 is a plan view of an intraocular pseudophakic contact lens 1800 including an optical lens 1802 and protrusions 1804a-1804b, which may be the same as or similar to the corresponding elements described above. Although protrusions 1804a-1804b are described as including holes configured to receive a plurality of anchors, this may not be required, such as when the tips of the anchors are embedded in protrusions 1804a-1804b.

[0064] The intraocular pseudophakic contact lens 1800 also includes a drug-eluting film 1806 formed on at least a portion of the optical lens 1802. In this example, the film 1806 is shown as a continuous section of the optical lens 1802 coated with a drug-eluting substance capable of delivering at least one drug. Any suitable drug can be applied to the optical lens 1802, and the application can be performed in any suitable application pattern or by any suitable method. In this example, the drug can be applied in a ring-shaped pattern, such as a ring having a thickness of approximately 0.5 mm. Other application methods that provide vision improvement with optical efficacy, such as a "slit design" in the optical center of the optical lens 1802, can also be used. By way of example, the film 1806 can be a drug-eluting hydrogel.

[0065] 19 is a perspective view of an intraocular pseudophakic contact lens 1900 including an optical lens 1902 and protrusions 1904a-1904b, which may be the same as or similar to the corresponding elements described above. Although protrusions 1904a-1904b are described as including holes configured to receive a plurality of anchors, this may not be required, such as when the tips of the anchors are embedded in protrusions 1904a-1904b.

[0066] The intraocular pseudophakic contact lens 1900 also includes a drug-eluting ring 1906 formed along at least a portion of the edge of the optic 1902. The ring 1906 elutes at least one drug into the patient's eye once implanted. The ring 1906 may or may not be continuously disposed around the entire circumference of the optic 1902. In some embodiments, one or more rings 1906 may be used, each of which is approximately 3 mm in length and approximately 0.5 mm in width. In certain embodiments, the ring 1906 may be a polyimide or other reservoir formed along the edge of the optic 1902.

[0067] It should be noted that Figures 17-19 illustrate specific examples of drug-eluting structures for intraocular pseudophakic contact lenses, however, any other type of drug-eluting structure or structures may be used at one or more locations on an intraocular pseudophakic contact lens.

[0068] Figure 20 is a cross-sectional view of an intraocular pseudophakic contact lens 2000 including an optic 2002, which may be the same as or similar to the corresponding elements described above. The intraocular pseudophakic contact lens 2000 also includes a plurality of protrusions 2004a-2004b. In the example described above, the protrusions extend away from the fixed optic at diagonal angles, thereby eliciting biological antagonism that helps ensure forward fixation of the anchor to the anterior surface of the intraocular lens. However, this may not be required, and the protrusions 2004a-2004b of the intraocular pseudophakic contact lens 2000 of Figure 20 generally extend linearly relative to one another. The holes 2006a-2006b in the protrusions 2004a-2004b can be formed straight vertically, as shown in FIG. 20, or can be formed at an angle (as shown in FIG. 19), which helps to orient the anchors inward toward the central axis of the optical lens 2002.

[0069] 21A-24 show various examples of optical lenses, which may include intraocular pseudophakic contact lenses. However, any other suitable optical lenses may be used for intraocular pseudophakic contact lenses. In FIGS. 21A and 21B, optical lenses 2100 and 2150 are shown with different thicknesses. Optical lens 2100 has a thicker center and is generally spherical on both the top and bottom sides. Optical lens 2150 has a thinner center and is somewhat flattened on the top side.

[0070] 22A and 22B show examples of optical lenses 2200 and 2250 with extensions 2202 and 2252, respectively. The extensions 2202 and 2252 have a greater mass than the corresponding portions of the optical lenses 2200 and 2250, and the greater mass of the extensions 2202 and 2252 causes the optical lenses 2200 and 2250 to be oriented as shown in FIGS. 22A and 22B. In other words, the optical lenses 2200 and 2250 have a non-uniform weight distribution around the central axis of the optical lenses 2200 and 2250. This example may be useful, for example, when the optical lenses 2200 and 2250 are spherical and require a specific orientation to correct for a refractive error (e.g., astigmatism) specific to the patient's eye. Extensions 2202 and 2252 are intended to refer to any extension of the optical lens, such as an extension end of the optical lens in one quadrant within the optical lens.

[0071] In Figure 22A, extension 2202 has top and bottom surfaces that are generally equivalent to the top and bottom surfaces of the end of optical lens 2200. Figure 22B is a perspective view highlighting the optical end. Extensions 2202 and 2252, respectively, allow intraocular pseudophakic contact lenses 2200 and 2250 to align the cylinder correction to the desired axis and provide a means for providing good stability and avoiding undesired rotation.

[0072] Figure 23 shows an example of an optical lens 2300, where the lens 2300 is a toric lens. A toric lens refers to a lens that has different refractive powers and focal lengths at different vertical orientations. This is shown in Figure 23, where the top surface 2302 of the optical lens 2300 is curved in one direction (perpendicular to the plane of the drawing) and the bottom surface 2304 of the optical lens 2300 is curved in the vertical direction (from left to right on the plane of the drawing).

[0073] Figure 24 shows an example of an aspheric optical lens 2400 that supports multifocality. In Figure 24, the optical lens 2400 includes a central portion 2402 and one or more annular portions 2404-2406 that surround the spherical portion 2402. The other sections 2402-2406 can be designed to provide different optical powers. For example, some of the sections 2402-2406 can be designed for near vision, while other sections of the sections 2402-2406 can be designed for distance vision.

[0074] Generally, a wide variety of optical lenses can be used in intraocular pseudophakic contact lenses to provide the desired refractive correction for patients with residual refractive error. One or more intraocular pseudophakic contact lenses for a particular patient can be selected or designed depending on the type of refractive correction required for the patient's eye.

[0075] While Figures 16-24 illustrate examples of other properties that may be utilized with intraocular pseudophakic contact lenses, various modifications may be made to Figures 16-24. For example, each intraocular pseudophakic contact lens or optical lens may include any number of the individual properties illustrated for the intraocular pseudophakic contact lens or optical lens. Also, other or additional properties may be utilized with the intraocular pseudophakic contact lenses described above.

[0076] FIG. 25 illustrates an example method 2500 for using an intraocular pseudophakic contact lens with an intraocular lens in accordance with the present disclosure. As shown in FIG. 25, the residual refractive error of a patient's eye fitted with the intraocular lens is determined in step 2502. This may include, for example, a medical professional testing the patient's visual acuity and determining whether any refractive error remains after implantation of the intraocular lens 1000. This testing may be performed in any suitable manner, such as using intraoperative wavefront aberrometry. One purpose of this testing is to determine what refractive error is present in the patient's eye after implantation of the intraocular lens. This testing may be performed at any suitable time, such as after a lensectomy procedure.

[0077] An intraocular pseudophakic contact lens is selected in step 2504 to (desirably) 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 substantially mitigates the identified residual refractive error. This 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 substantially eliminating the identified residual refractive error. This may also include the practitioner obtaining an intraocular pseudophakic contact lens with a specially designed optical lens, or obtaining specially designed optical lenses for insertion into the intraocular pseudophakic contact lens, the specially designed optical lenses substantially eliminating the identified residual refractive error. Generally, any means may be used to obtain a suitable intraocular pseudophakic contact lens.

[0078] The selected intraocular pseudophakic contact lens is inserted into the patient's eye at step 2506. This may involve, for example, a surgeon or other personnel making a small incision in the patient's eye and inserting the intraocular pseudophakic contact lens into the eye through the incision. In order to insert the intraocular pseudophakic contact lens through the small incision, the intraocular pseudophakic contact lens may be rolled, folded, or otherwise reduced in cross-sectional size.

[0079] One or more anchors are used to secure the intraocular pseudophakic contact lens to the intraocular lens in the patient's eye, step 2508. This may include, for example, a surgeon or other personnel placing the intraocular pseudophakic contact lens in a desired position (and, if possible, in a desired orientation) over the intraocular lens. This may also include a surgeon or other personnel pushing the intraocular pseudophakic contact lens or anchors of the intraocular pseudophakic contact lens to drive the anchors into the lens material of the intraocular lens in the patient's eye. This may also include placing haptic loops of the intraocular pseudophakic contact lens around a portion of the lens capsule in the patient's eye.

[0080] In step 2510, 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 in which the intraocular pseudophakic contact lens is implanted or after the surgical procedure is completed. In step 2512, it is determined whether the tested visual acuity is satisfactory. This may include, for example, determining whether the patient's eye still has residual refractive error, and if so, the degree of the error.

[0081] At step 2514, a determination is made as to whether the intraocular pseudophakic contact lens should be replaced. This may include, for example, determining whether the practitioner and patient are bothered by or are concerned about any residual refractive error (if any). If so, other measures may be taken to analyze and resolve the issue. For example, the implantation position of the currently implanted intraocular pseudophakic contact lens may be readjusted to correct the cylinder axis. If this is unsuccessful, at step 2516, another intraocular pseudophakic contact lens is selected. This may include, for example, the practitioner selecting another intraocular pseudophakic contact lens that (hopefully) provides better refractive correction to the patient's eye than the currently inserted intraocular pseudophakic contact lens. At step 2518, the currently inserted intraocular pseudophakic contact lens is removed from the patient's eye. This action may include, for example, the surgeon or other personnel removing the anchor of the currently inserted intraocular pseudophakic contact lens from the lens material of the intraocular lens and removing the currently inserted intraocular pseudophakic contact lens from the patient's eye, and the process then returns to step 2506, where a newly selected intraocular pseudophakic contact lens can be inserted into the patient's eye and the vision test can be repeated.

[0082] While Figure 25 illustrates one example of a method 2500 for using an intraocular pseudophakic contact lens with an intraocular lens, various modifications can be made to Figure 25. For example, although shown as a series of steps, the various steps illustrated in Figure 25 may overlap, be performed in parallel, be performed in a different order, or be performed any number of times.
