Abstract
Abstract A method for altering the pupil of an eye is shown. The method comprises the step of surgically performing an iridectomy superiorly to the natural pupil of an eye forming a superior accessory pupil to accommodate an optical lens system. In the preferred embodiment, the optical lens system is an artificial lens system having a first optical lens system and a second optical lens system and at least one of the first optical lens system and the second optical lens system includes a prism positioned on a selected surface thereof for passing light rays of an object through eccentrically arranged lens to the macula.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
132 words
A method for producing multiple images of an object for an eye using an artificial lens system having at least two lenses which are supported in the eye so as to be situated eccentrically from one another and which are capable of directing light rays from multiple images to the macula comprising the steps of: forming an opening in the iris superior of the natural pupil; positioning one of said at least two lenses in the natural pupil; and positioning another of said at least two lenses in said opening in the iris such that an optical axis of the second lens is eccentric to an optical axis of the first lens for directing light rays from images respectively produced by said first and second lenses onto the macula of an eye.
Claim 2
Independent Claim
132 words
A method for producing multiple images of an object for an eye using an artificial lens system having at least two lenses which are supported in the eye so as to be situated eccentrically from one another and which are capable of directing light rays from multiple images to the macula comprising the steps of: forming an opening in the iris superior of the natural pupil; positioning one of said at least two lenses in the natural pupil; and positioning another of said at least two lenses in said opening in the iris such that an optical axis of the second lens is eccentric to an optical axis of the first lens for directing light rays from images respectively produced by said first and second lenses onto the macula of an eye.
Claim 3
Dependent Claim
32 words
The method of claim 1 wherein the step of forming an opening in the iris comprises forming a separate accessory pupil in the eye spaced from and superior to the natural pupil.
Claim 4
Dependent Claim
32 words
The method of claim 1 wherein the step of forming an opening in the iris comprises forming an enlarged opening in the natural pupil thereby forming a vertically extending natural pupil opening.
Claim 5
Dependent Claim
14 words
The method of claim 3 wherein said vertically extending natural pupil opening is elliptically-shaped.
Claim 6
Dependent Claim
18 words
The method of claim 1 wherein the step of forming an opening is performed using an Argon laser.
Claim 7
Dependent Claim
18 words
The method of claim 1 wherein the step of forming an opening is performed using a Yag laser.
Claim 8
Dependent Claim
18 words
The method of claim 1 wherein the step of forming an opening is performed using a sector iridectomy.
Claim 9
Dependent Claim
24 words
The method of claim 1 wherein a prism is positioned on a selected surface of at least one of said at least two lenses.
Claim 10
Dependent Claim
62 words
The method of claim 1 wherein the eye has a posterior capsule and further comprising the step of: performing a capsulorhexis procedure on the posterior capsule to form a least one opening in the posterior capsule to enable a distal end of a posterior surface portion of at least one of said at least two lenses to extend into the vitreous humor.
