Abstract

To the Editor:  We read with interest the article of Dr. Robert D. Mattis et al in the December, 1965 issue of the Archives. We have been interested in evaluating cryoextraction as a technique in cataract removal and have designed an instrument using the same principle as the one inspired by Dr. Sudarsky and evaluated by Dr. Mattis.Our instrument was designed to be as simple and lightweight as possible to assure its safety and maneuverability. Commercially available materials were selected for its construction to lower costs.The cryoextractor is made from a 5-cc, disposable plastic syringe fitted with a tip of pure silver wire 1/16th of an inch in diameter. The tip is bent at an angle of 35°, insulated with plastic tubing, and bonded to the syringe with epoxy resin. Assembled, it is 9 cm long and weighs only 4 gm.The refrigerant for the instrument is Freon
