## 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.

## Claims

### Claim at position 1

1-9. (canceled)

### Claim 10

An intraocular lens assembly for positioning in a lens capsule of a patient's eye, comprising:
a lens optic assembly including an optic portion and a surface surrounding a sidewall of the optic portion, the lens optic assembly being shaped for positioning in a capsulorhexis incision in the patient's lens and focusing light passing therethrough, wherein the optic portion comprises a lens having a registration feature in a peripheral edge of the lens;
two spring haptics, each haptic being coupled to the lens optic assembly at a different juncture, each haptic comprising a first end coupled to the lens optic assembly and second end disposed outward from and unconnected to the lens optic assembly, the two spring haptics being shaped for supplying a spring force to the lens optic assembly within the lens capsule of the patient's eye when the lens is implanted therein.

### Claim 11 (depends on 10)

The intraocular lens assembly of claim 10, wherein the registration feature is a protrusion that radially extends from the peripheral edge.

### Claim 12 (depends on 11)

The intraocular lens assembly of claim 11, wherein the edge of the protrusion is round.

### Claim 13 (depends on 12)

The intraocular lens assembly of claim 12, wherein lens is round except where the protrusion extends from the peripheral edge.

### Claim 14 (depends on 10)

The intraocular lens assembly of claim 10, wherein the registration feature is configured to mate with a matching registration feature in a capsularhexis incision.

### Claim 15 (depends on 10)

The intraocular lens assembly of claim 10, wherein the lens is an astigmatic lens.

### Claim 16 (depends on 15)

The intraocular lens assembly of claim 15, wherein the registration feature is shaped for positioning in a registration incision such that the intraocular lens resists rotation about an optical axis of the lens optic assembly when the intraocular lens is positioned in the patient's eye.

### Claim 17 (depends on 10)

The intraocular lens assembly of claim 10, wherein the haptics are shaped so as to secure positioning of the intraocular lens when positioned in the patient's eye.

### Claim 18

An intraocular lens assembly for positioning in a lens capsule of a patient's eye, consisting of:
a lens optic assembly including an optic portion and a surface surrounding an edge of the optic portion, the lens optic assembly being shaped for positioning in a capsulorhexis incision in the patient's lens and focusing light passing therethrough, wherein the optic portion comprises a lens having a registration feature in a peripheral edge of the lens;
exactly two spring haptics, each haptic being coupled to the lens optic assembly at a different juncture, the two haptics extending from the lens optic assembly and shaped for supplying a spring force to the lens optic assembly within the lens capsule of the patient's eye when the lens is implanted therein.

### Claim 19 (depends on 18)

The intraocular lens assembly of claim 18, wherein the registration feature is a protrusion that radially extends from the peripheral edge.

### Claim 20 (depends on 19)

The intraocular lens assembly of claim 19, wherein the edge of the protrusion is round.

### Claim 21 (depends on 20)

The intraocular lens assembly of claim 20, wherein lens is round except where the protrusion extends from the peripheral edge.

### Claim 22 (depends on 18)

The intraocular lens assembly of claim 18, wherein the registration feature is configured to mate with a matching registration feature in a capsularhexis incision.

### Claim 23 (depends on 18)

The intraocular lens assembly of claim 18, wherein the lens is an astigmatic lens.

### Claim 24 (depends on 23)

The intraocular lens assembly of claim 23, wherein the registration feature is shaped for positioning in a registration incision such that the intraocular lens resists rotation about an optical axis of the lens optic assembly when the intraocular lens is positioned in the patient's eye.

### Claim 25 (depends on 18)

The intraocular lens assembly of claim 18, wherein the haptics are shaped so as to secure positioning of the intraocular lens when positioned in the patient's eye.
