Abstract

Claims (60)

1. An apparatus comprising:

an intraocular pseudophakic contact lens comprising:

an optical lens; and

haptics extending radially from the optical lens and configured to contact a capsular bag in an eye in order to secure the intraocular pseudophakic contact lens against an artificial intraocular lens;

wherein the optical lens comprises a central portion and at least one annular portion surrounding the central portion, the central and annular portions configured to provide different optical powers;

wherein anterior surfaces of the haptics comprise capsular wall-engaging surfaces configured to contact an inner capsular wall surface at an anterior leaflet of the capsular bag, the capsular wall-engaging surfaces configured to promote confinement, capture, or attachment of the haptics;

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

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 of the capsular bag against the outer portions of the haptics.

2. The apparatus of claim 1 , wherein:

the central portion of the optical lens is configured to provide a central optical magnification; and

the at least one annular portion of the optical lens is configured to provide no optical magnification.

3. The apparatus of claim 2 , wherein:

the central portion of the optical lens comprises a convex anterior surface and a concave posterior surface; and

each annular portion of the optical lens comprises a convex anterior surface and a concave posterior surface.

4. The apparatus of claim 1 , wherein one of the haptics comprises an alignment marking identifying a desired orientation of the intraocular pseudophakic contact lens in the eye.

5. The apparatus of claim 1 , wherein the central portion of the optical lens is configured to provide an optical power of about +5 diopters to about +11 diopters.

6. The apparatus of claim 1 , wherein:

the central portion of the optical lens is configured to provide a central optical magnification; and

the at least one annular portion of the optical lens is configured to provide at least one different optical magnification.

7. The apparatus of claim 6 , wherein:

the central portion of the optical lens comprises a convex anterior surface and a concave posterior surface; and

each annular portion of the optical lens comprises a convex anterior surface and a concave posterior surface.

8. The apparatus of claim 7 , wherein a convexity of the convex anterior surface of the central portion is greater than a convexity of the convex anterior surface of each annular portion.

9. The apparatus of claim 1 , wherein the haptics comprise three haptics configured to center the intraocular pseudophakic contact lens on the artificial intraocular lens.

10. A system comprising:

an artificial intraocular lens comprising a first optical lens and first haptics configured to be implanted within a capsular bag in an eye; and

an intraocular pseudophakic contact lens comprising:

a second optical lens; and

second haptics extending radially from the second optical lens and configured to contact the capsular bag in order to secure the intraocular pseudophakic contact lens against the artificial intraocular lens;

wherein the second optical lens comprises a central portion and at least one annular portion surrounding the central portion, the central and annular portions configured to provide different optical powers;

wherein anterior surfaces of the second haptics comprise capsular wall-engaging surfaces configured to contact an inner capsular wall surface at an anterior leaflet of the capsular bag, the capsular wall-engaging surfaces configured to promote confinement, capture, or attachment of the second haptics;

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

wherein the second haptics are flexible such that outer portions of the second 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 of the capsular bag against the outer portions of the second haptics.

11. The system of claim 10 , wherein:

the central portion of the second optical lens is configured to provide a central optical magnification; and

the at least one annular portion of the second optical lens is configured to provide no optical magnification.

12. The system of claim 11 , wherein:

the central portion of the second optical lens comprises a convex anterior surface and a concave posterior surface; and

each annular portion of the second optical lens comprises a convex anterior surface and a concave posterior surface.

13. The system of claim 10 , wherein one of the second haptics comprises an alignment marking identifying a desired orientation of the intraocular pseudophakic contact lens in the eye.

14. The system of claim 10 , wherein the central portion of the second optical lens is configured to provide an optical power of about +5 diopters to about +11 diopters.

15. The system of claim 10 , wherein:

the central portion of the second optical lens is configured to provide a central optical magnification; and

the at least one annular portion of the second optical lens is configured to provide at least one different optical magnification.

16. The system of claim 15 , wherein:

the central portion of the second optical lens comprises a convex anterior surface and a concave posterior surface; and

each annular portion of the second optical lens comprises a convex anterior surface and a concave posterior surface.

17. The system of claim 16 , wherein a convexity of the convex anterior surface of the central portion is greater than a convexity of the convex anterior surface of each annular portion.

18. The system of claim 10 , wherein the second haptics comprise three haptics configured to center the intraocular pseudophakic contact lens on the artificial intraocular lens.

19. The system of claim 10 , wherein the second haptics are shorter than the first haptics.

20. An apparatus comprising:

an intraocular pseudophakic contact lens comprising:

an optical lens; and

haptics extending radially from the optical lens and configured to contact a capsular bag in an eye in order to secure the intraocular pseudophakic contact lens against an artificial intraocular lens;

wherein the optical lens comprises a central portion and at least one annular portion surrounding the central portion, the central and annular portions configured to provide different optical powers;

wherein anterior surfaces of the haptics comprise capsular wall-engaging surfaces configured to contact an inner capsular wall surface at an anterior leaflet of the capsular bag, the capsular wall-engaging surfaces configured to promote confinement, capture, or attachment of the haptics;

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 of the capsular bag against the outer portions of the haptics;
