AI Technical Summary
Technical Problem
Existing capsulorhexis procedures using capsulorhexis forceps often result in imperfect hole formation in the lens capsule, leading to surgical complications such as instability of the artificial lens and unintentional tearing.
Method used
An ultrasonic instrument with a tube and a horn, featuring a cable loop that oscillates at an ultrasonic frequency to remove a portion of the lens capsule, forming a precise circular hole without repeated grasping and tearing.
Benefits of technology
Minimizes surgical complications by creating a consistently sized and shaped hole in the lens capsule, reducing the need for skilled manual manipulation.

Abstract
A surgical instrument includes a tube and a horn. The tube has a distal end and a proximal end. A loop is formed with a cable that is folded between a first end of the cable and a second end of the cable. The cable is at least partially disposed in the tube. The horn is configured to oscillate. The first end of the cable is coupled to the horn. An oscillation of the horn actuates the cable.
