WITH the increasing popularity of cryoextraction of cataracts, various methods have been described to deal with the iris in such a way that, when the tip of the cryoextractor is applied to the lens, there will be plenty of room so that the iris is not also frozen to the extractor.
A sector iridectomy simplifies iris retraction but the problem remains that for a round pupil extraction some method of retraction of the lens, an absorbable sponge cut retractors have been devised for this purpose.
This brief presentation reports a simplified method which has some advantages for lens extraction with either a round pupil or a sector iridectomy.
When the surgeon is ready to begin extraction of the lens, an absorbable sponge cut in a triangular shape on the end of a small hemostat is inserted into the anterior chamber, and the excess fluid and aqueous is rapidly absorbed. A
