Abstract
Abstract Surgical apparatus and method for incising an aperture in the anterior capsule of the human eye. The apparatus for capsulorhexis comprises a shaft, a cutting member with a sharp cutting edge, and a fastener connecting the shaft to an ultrasonic power source. After making an initial incision in the eye, the surgeon uses the apparatus to make a smooth, continuous, curvilinear aperture in the anterior capsule of the eye.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
137 words
Apparatus for incising an aperture in the anterior capsule of the human eye comprising: a solid shaft having first and second ends; a cutting member attached to the shaft, said cutting member having first, second and third orthogonal axes wherein the first and second axes define a horizontal plane of said cutting member and the third axis defines the depth of said cutting member, said cutting member comprising a metal band having a physical configuration defined by the first and second axes, with the width of said band substantially equal to the length of said third axis, said metal band having at least one opening therein receiving said shaft therethrough and having a cutting edge; and means for connecting the first end of said shaft to an ultrasonic power source to impart motion to the cutting edge.
Claim 2
Dependent Claim
137 words

Apparatus for incising an aperture in the anterior capsule of the human eye comprising: a deformable, circular cutting member of a metal alloy, said member having a cutting edge and at least two openings therein; a solid shaft having first and second ends said shaft attached to said circular cutting member such that said shaft passes through the openings in said cutting member; and a fastener on the first end of said shaft adapted to connect said first end of said shaft to an ultrasonic power source to impart motion to the cutting edge.
Claim 14
Dependent Claim
94 words
Apparatus for incising an aperture in the anterior capsule of the human eye comprising: a deformable, circular cutting member of a metal alloy, said member having a cutting edge and at least two openings therein; a solid shaft having first and second ends said shaft attached to said circular cutting member such that said shaft passes through the openings in said cutting member; and a fastener on the first end of said shaft adapted to connect said first end of said shaft to an ultrasonic power source to impart motion to the cutting edge.
Claim 15
Dependent Claim
98 words
Apparatus for incising an aperture in the anterior capsule of the human eye comprising: a "C"-shaped cutting member of a metal alloy, said member having a cutting edge and at least one opening therein; a solid shaft having first and second ends, said shaft attached to said c-shaped cutting member such that wherein the second end of the shaft passes through the opening in said cutting member; and a fastener on the first end of said shaft adapted to connect said first end of said shaft to an ultrasonic power source to impart motion to the cutting edge.
Claim 16
Dependent Claim
