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 peripheral member disposed around the lens portion and mechanically coupled to the lens portion, the peripheral member having a shape that is rotationally asymmetrical around an optical axis of the lens portion, wherein the lens portion is configured to rotate within the peripheral member; and
a post and a strut member, wherein the post is separate from and connected to the lens portion by the strut member.

2. The intraocular lens of claim 1 , wherein the peripheral member includes a ring having one or more haptics which extend away from the lens portion, wherein the lens portion is configured to rotate within the ring.

3. The intraocular lens of claim 2 , wherein the ring and the lens portion each includes one or more alignment marks.

4. The intraocular lens of claim 1 , wherein the shape of the peripheral member is one which, when rotated around the optical axis of the lens portion, coincides with itself only after a 360° rotation.
