New disposable cystotome for capsulorhexis

Circular tear capsulotomy, or capsulorhexis, is becoming an increasingly popular method of anterior capsulotomy. We describe a new cystotome with a simple tip modification which is useful for performing a circular tear capsulotomy. The cystotome is a 27 gauge disposable device that is similar to a conventional cystotome used for a can-opener-type capsulotomy except for its unique but simple tip modification. The beveled tip is first bent at 90 degrees and then twisted on its main axis so that the beveled cutting edge is parallel (i.e., in the same axis) to the shaft of the cystotome. We also briefly describe its method of use.
