Abstract

An intraocular lens that is capable of being inserted through a micro-incision includes an optic having an anterior and a posterior surface and a plurality of projections extending from the anterior and posterior surfaces. The anterior and posterior surfaces include a recess. The optic is implanted such that a rim of the capsulorhexis is disposed in the recess such that the plurality of projections grip the capsular bag.

First claim

What is claimed is:

1. An intraocular lens comprising: an optic disposed about an optical axis, the optic having an anterior surface and a posterior surface; at least two anterior projections coupled to and extending radially from the optic; and at least two posterior projections adjacent to the at least two anterior projections, wherein the at least two posterior projections are coupled to and extends radially from the optic, wherein the anterior and posterior projections are resiliently biased such that distal ends of the anterior projections and the posterior projections can be moved away from and toward each other, and wherein, when implanted, the distal ends of the at least two anterior projections and the at least two posterior projections are configured to grip an outside surface and an inside surface adjacent to a capsulorhexis on an anterior portion of an evacuated capsular bag.

2. The intraocular lens of claim 1 , wherein the anterior and posterior projections are actuated by axially compressing a zone disposed between the optic and distal ends of the anterior and/or posterior projections.

3. The intraocular lens of claim 1 , wherein, when implanted in the eye, the optic is subject to a stretching force applied transverse to the optical axis.

4. The intraocular lens of claim 3 , wherein the stretching force is distributed uniformly across the surface of the optic.

5. The intraocular lens of claim 1 , further comprising a recess between the anterior and posterior projections.

6. The intraocular lens of claim 5 , wherein, when implanted, the rim of the capsulorhexis is disposed in the recess.

7. The intraocular lens of claim 1 , wherein, when implanted in the eye, the optic is located partially in the capsular bag and partially outside the capsular bag.
