Abstract

An ophthalmic lens may comprise a posterior optic surface and an anterior optic surface, which may comprise a central optic, a peripheral optic, and a capsule rim separating the central optic and the peripheral optic. An optic edge may couple the posterior optic surface to the peripheral optic. The capsule rim may be symmetric or asymmetric in various embodiments. In more particular embodiments, the capsule rim may form a surface at an angle of at least ninety (90) degrees to the peripheral optic. In some embodiments, the central optic may comprise an optic axis, and the capsule rim may form a surface that is substantially parallel to the optic axis.

First claim

What is claimed is:

1 . An ophthalmic lens comprising:
a posterior optic surface; an anterior optic surface comprising a central optic, a peripheral optic, and a capsule rim separating the central optic and the peripheral optic; and an optic edge coupling the posterior optic surface to the peripheral optic.

2 . The ophthalmic lens of claim 1 , wherein the capsule rim is symmetric.

3 . The ophthalmic lens of claim 1 , wherein the capsule rim is asymmetric.

4 . The ophthalmic lens of claim 1 , wherein the capsule rim forms a surface at an angle of at least 90 degrees to the peripheral optic.

5 . The ophthalmic lens of claim 1 , wherein the central optic comprises an optic axis and the capsule rim forms a surface that is substantially parallel to the optic axis.

6 . The ophthalmic lens of claim 1 , wherein the capsule rim has a thickness in a range of about 19 micrometers to about 20 micrometers.

7 . The ophthalmic lens of claim 1 , wherein the capsule rim has a thickness substantially equal to a thickness of an anterior capsular bag.

8 . The ophthalmic lens of claim 1 , wherein the capsule rim has a radius in a range of about 2 millimeters to about 3 millimeters.

9 . The ophthalmic lens of claim 1 , wherein the peripheral optic comprises a textured surface.

10 . The ophthalmic lens of claim 9 , wherein the textured surface is configured to diffuse light.

11 . The ophthalmic lens of claim 1 , further comprising a transition band configured to diffuse or redirect light.

12 . The ophthalmic lens of claim 1 , wherein the central optic is recessed.

13 . The ophthalmic lens of claim 1 , further comprising at least two haptics coupled to the optic edge.

14 . The ophthalmic lens of claim 1 , wherein the capsule rim is configured to sequester an edge of a capsulorhexis opening.

15 . An ophthalmic lens comprising:
a posterior optic surface; an anterior optic surface comprising a central optic, a peripheral optic, and a capsule rim separating the central optic and the peripheral optic; and an optic edge coupling the posterior optic surface to the peripheral optic; wherein the capsule rim comprises a closed curve having at least one convex arc and at least one concave arc.

16 . The ophthalmic lens of claim 15 , wherein the capsule rim is symmetric.

17 . The ophthalmic lens of claim 15 , wherein the capsule rim is asymmetric.

18 . A method of implanting an intraocular lens into a capsular bag of an eye, the method comprising:
creating a capsulorhexis in an anterior portion of the capsular bag; removing the natural lens from the capsular bag; and inserting the intraocular lens into the capsular bag, wherein the intraocular lens comprises an anterior optic surface having a peripheral optic disposed within the capsular bag, a capsular rim adjacent to an edge of the capsulorhexis, and a central optic disposed within the capsulorhexis and substantially flush with the capsular bag.

19 . The method of claim 18 , wherein the central optic has a width larger than a width of the capsulorhexis to create tension in the capsulorhexis.

20 . The method claim 18 , wherein the peripheral optic comprises a textured surface configured to scatter light transmission.
