Abstract

A method of performing laser surgery in a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form an enclosed treatment pattern that is configured to form an enclosed capsulorhexis incision that includes a registration feature, and delivering the enclosed treatment pattern to target tissue in the patient's eye to form in an anterior lens capsule of the patient's eye the enclosed capsulorhexis incision that includes the registration feature. The registration feature is configured so that an edge of the target tissue formed by the enclosed capsulorhexis incision mates with an intraocular lens registration feature on an intraocular lens so as to rotationally register the intraocular lens relative to the registration feature.

First claim

What is claimed is:

1. A method of performing laser surgery in a patient's eye, comprising:
generating a light beam;
deflecting the light beam using a scanner to form an enclosed capsulorhexis treatment pattern and a registration pattern;
delivering the enclosed treatment pattern and the registration pattern to target tissue in the patient's eye to form an enclosed capsulorhexis incision and a separate and distinct registration incision in the patient's eye,
wherein the capsulorhexis incision is configured so that an edge of the target tissue formed by the capsulorhexis incision is capable of accommodating an intraocular lens within the enclosed capsulorhexis incision;
wherein the registration incision is configured so that an edge of the tissue formed by the registration incision is capable of mating with an intraocular lens registration feature on an intraocular lens so as to rotationally register the intraocular lens relative to the registration feature.

2. The method of claim 1 , wherein the registration pattern is a circular pattern.

3. The method of claim 1 , wherein the intraocular lens registration feature is a post disposed atop a strut of the intraocular lens.

4. The method of claim 1 , wherein the target tissue comprises one or both of an anterior lens capsule and a posterior lens capsule.

5. The method of claim 1 , wherein the target tissue comprises the anterior lens capsule.

6. The method of claim 1 , wherein the registration incision is configured so that the edge of the tissue formed by the registration incision is capable of mating with the intraocular lens registration features so as to rotationally align the intraocular lens to an astigmatic axis of the patient's eye.

7. A method of performing laser surgery in a patient's eye, comprising:
generating a laser light beam;
deflecting the laser light beam, using a scanner, so as to deliver a laser light beam in a treatment pattern to a target tissue in the patient's eye and effect an incision pattern in an anterior capsule of a lens of the patient's eye, the incision pattern comprising a registration feature incision and a capsulorhexis incision, wherein the capsulorhexis incision and registration feature incision are spaced apart so as to form separate and distinct incisions in the lens anterior capsule,
wherein the registration feature incision is configured so that an edge of the tissue formed by the registration feature incision is capable of mating with an intraocular lens registration feature on an intraocular lens so as to rotationally register the intraocular lens relative to the registration feature.

8. The method of claim 7 , wherein the capsulorhexis incision is a circular incision.
