Cortex removal system for manual extracapsular cataract extraction

Abstract

An irrigation/aspiration (I/A) system for cortex removal has been developed. It consists of an I/A cannula, connecting silicone tube, a handle with an aspiration cut-off device for the silicone tube, and an aspirating device. The aspirating pressure is produced by a fixed syringe, the cylinder of which is pulled by a weight. In addition, the aspirating system can be equipped with a small battery-operated pump. The aspiration cut-off device located in the handle enables aspiration with one hand so the other hand is free for another instrument. Flushing back, if necessary, is possible.
