Abstract

Claims (56)

1. An apparatus comprising:

an intraocular pseudophakic contact lens configured to be implanted in an eye and mounted on or attached to an artificial intraocular lens in the eye;

wherein the intraocular pseudophakic contact lens comprises (i) an optical lens and (ii) haptics extending radially from the optical lens and configured to be inserted under an anterior leaflet of a capsular wall in the eye;

wherein the optical lens comprises (i) a central portion comprising a concave anterior surface and a concave posterior surface and (ii) an annular portion surrounding the central portion and comprising a convex anterior surface and a concave posterior surface;

wherein anterior surfaces of the haptics comprise capsular wall-engaging surfaces configured to contact an inner capsular wall surface at the anterior leaflet of the capsular wall;

wherein posterior surfaces of the haptics comprise ridges configured to capture at least one edge of the artificial intraocular lens;

wherein the haptics are flexible such that outer portions of the haptics are configured to drive the ridges into the at least one edge of the artificial intraocular lens based on surface pressure from the anterior leaflet against the outer portions of the haptics; and

wherein the haptics extend outward and posteriorly from the optical lens such that at least part of the optical lens remains spaced apart from the artificial intraocular lens after the ridges capture the at least one edge of the artificial intraocular lens.

2. The apparatus of claim 1 , wherein the optical lens of the intraocular pseudophakic contact lens is configured to provide a minus power optical magnification.

3. The apparatus of claim 2 , wherein the optical lens of the intraocular pseudophakic contact lens is configured to provide an optical power of about −5 diopters to about −25 diopters.

4. The apparatus of claim 1 , wherein the intraocular pseudophakic contact lens comprises at least three haptics.

5. The apparatus of claim 1 , wherein the anterior surfaces of the haptics comprise textured surfaces.

6. The apparatus of claim 1 , wherein:

the central portion is configured to provide a minus power optical magnification; and

the annular portion is configured to provide a different power optical magnification.

7. The apparatus of claim 1 , wherein the intraocular pseudophakic contact lens further comprises at least one alignment marking positioned on at least one of the haptics and configured to identify proper orientation of the intraocular pseudophakic contact lens.

8. The apparatus of claim 1 , wherein:

each haptic comprises an inner portion in addition to the outer portion;

the inner portion of each haptic is positioned between the optical lens and the outer portion of the haptic; and

for each haptic, the ridge is defined where a larger thickness of the outer portion of the haptic meets a smaller thickness of the inner portion of the haptic.

9. The apparatus of claim 1 , wherein:

the central portion is configured to provide optical magnification; and

the annular portion is configured to provide no optical magnification.

10. The apparatus of claim 1 , wherein the optical lens of the intraocular pseudophakic contact lens is multi-focal.

11. A system comprising:

an artificial intraocular lens; and

an intraocular pseudophakic contact lens configured to be implanted in an eye and mounted on or attached to the artificial intraocular lens;

wherein the intraocular pseudophakic contact lens comprises (i) an optical lens and (ii) haptics extending radially from the optical lens and configured to be inserted under an anterior leaflet of a capsular wall in the eye;

wherein the optical lens comprises (i) a central portion comprising a concave anterior surface and a concave posterior surface and (ii) an annular portion surrounding the central portion and comprising a convex anterior surface and a concave posterior surface;

wherein anterior surfaces of the haptics comprise capsular wall-engaging surfaces configured to contact an inner capsular wall surface at the anterior leaflet of the capsular wall;

wherein posterior surfaces of the haptics comprise ridges configured to capture at least one edge of the artificial intraocular lens;

wherein the haptics are flexible such that outer portions of the haptics are configured to drive the ridges into the at least one edge of the artificial intraocular lens based on surface pressure from the anterior leaflet against the outer portions of the haptics; and

wherein the haptics extend outward and posteriorly from the optical lens such that at least part of the optical lens remains spaced apart from the artificial intraocular lens after the ridges capture the at least one edge of the artificial intraocular lens.

12. The system of claim 11 , wherein the optical lens of the intraocular pseudophakic contact lens is configured to provide a minus power optical magnification.

13. The system of claim 12 , wherein the optical lens of the intraocular pseudophakic contact lens is configured to provide an optical power of about −5 diopters to about −25 diopters.

14. The system of claim 11 , wherein the anterior surfaces of the haptics comprise textured surfaces.

15. The system of claim 11 , wherein:

the central portion is configured to provide a minus power optical magnification; and

the annular portion is configured to provide a different power optical magnification.

16. The system of claim 11 , wherein the intraocular pseudophakic contact lens further comprises at least one alignment marking positioned on at least one of the haptics and configured to identify proper orientation of the intraocular pseudophakic contact lens.

17. The system of claim 11 , wherein:

each haptic comprises an inner portion in addition to the outer portion;

the inner portion of each haptic is positioned between the optical lens and the outer portion of the haptic; and

for each haptic, the ridge is defined where a larger thickness of the outer portion of the haptic meets a smaller thickness of the inner portion of the haptic.

18. The system of claim 11 , wherein:

the central portion is configured to provide optical magnification; and

the annular portion is configured to provide no optical magnification.

19. The system of claim 11 , wherein the optical lens of the intraocular pseudophakic contact lens is multi-focal.

20. A method comprising:

mounting or attaching an intraocular pseudophakic contact lens to an artificial intraocular lens;

wherein the intraocular pseudophakic contact lens comprises (i) an optical lens and (ii) haptics extending radially from the optical lens and configured to be inserted under an anterior leaflet of a capsular wall in an eye;

wherein the optical lens comprises (i) a central portion comprising a concave anterior surface and a concave posterior surface and (ii) an annular portion surrounding the central portion and comprising a convex anterior surface and a concave posterior surface;

wherein anterior surfaces of the haptics comprise capsular wall-engaging surfaces configured to contact an inner capsular wall surface at the anterior leaflet of the capsular wall;

wherein posterior surfaces of the haptics comprise ridges configured to capture at least one edge of the artificial intraocular lens;

wherein the haptics are flexible such that outer portions of the haptics are configured to drive the ridges into the at least one edge of the artificial intraocular lens based on surface pressure from the anterior leaflet against the outer portions of the haptics; and

wherein the haptics extend outward and posteriorly from the optical lens such that at least part of the optical lens remains spaced apart from the artificial intraocular lens after the ridges capture the at least one edge of the artificial intraocular lens.
