Abstract

A system and method for inserting an intraocular lens in a patient's eye includes a light source for generating a light beam, a scanner for deflecting the light beam to form an enclosed treatment pattern that includes a registration feature, and a delivery system for delivering the enclosed treatment pattern to target tissue in the patient's eye to form an enclosed incision therein having the registration feature. An intraocular lens is placed within the enclosed incision, wherein the intraocular lens has a registration feature that engages with the registration feature of the enclosed incision. Alternately, the scanner can make a separate registration incision for a post that is connected to the intraocular lens via a strut member.

First claim

What is claimed is:

1. An intraocular lens for replacing a natural lens in a lens capsule of a patient's eye, the intraocular lens comprising:
a lens portion configured to focus light passing therethrough;
a post separated from and fixedly connected to the lens portion by a strut member, the post being shaped to be received in a registration incision in the lens capsule so as to orient the intraocular lens, the post and the strut member being integral to the lens portion and located at a predetermined angular position with respect to the lens portion; and
a ring surrounding the lens portion, wherein the lens portion, the post and the strut member are rotatable relative to a central axis of the ring, and wherein the post is located at a radial position outside of an outer edge of the ring.

2. The intraocular lens of claim 1 , further comprising at least two haptics extending from the lens portion for supplying a spring force to the lens portion.

3. The intraocular lens of claim 1 , wherein the post is disposed atop the strut member.

4. The intraocular lens of claim 1 , wherein the lens portion comprises an astigmatic lens.

5. The intraocular lens of claim 1 , wherein the lens portion has an edge configured to be seated in a capsulorhexis incision and the intraocular lens further comprises an outer portion surrounding the edge and providing a surface that provides a resting place for the lens capsule.

6. The intraocular lens of claim 2 , wherein the lens portion has an edge configured to be seated in a capsulorhexis incision and the intraocular lens further comprises an outer portion surrounding the edge and providing a surface that provides a resting place for the lens capsule.

7. The intraocular lens of claim 6 , wherein the at least two haptics are configured to seat the edge in the capsulorhexis incision by apply a retaining force to the lens portion towards the anterior portion of the lens capsule.
