Phacoemulsification Without Ultrasound
1993
Abstract OBJECTIVE: to produce grooving of cataract without using ultrasound energy. BASIC PROBLEM: Phacoemulsification is expensive. YAG, laser energy can be used to demonstrate both lamellar and radial structure within the nucleus of cataractous lenses. This knowledge gives a rational basis for the grooving of a cataract in phacoemulsification. RESULTS: We find that grooving can also be accomplished using a sharpened Charleux cannula in most cases. The fragments can be delivered with an irrigating spoon. CONCLUSIONS: This knowledge allows inexpensive planned extracapsular cataract extraction through a small wound.
