The Koch endocapsular punch. A report on its use in 96 consecutive cases.

Abstract

The technique of endocapsular cataract extraction and intraocular lens implantation surgery provides optimal surgical conditions and more reliable intraocular lens positioning in the capsular bag. Several capsulectomy techniques are in use to remove anterior capsule from the central zone. The Koch endocapsular punch provides a new technique for creating a continuous anterior capsulectomy. In this study the Koch punch was used in 96 eyes consecutively undergoing intended endocapsular cataract extraction and intraocular lens implantation. Ninety-five eyes had appropriate lens centration at six months. There were no cases of vitreous loss. Ninety-nine per cent of cases had visual acuity of 6/6 or better at six months. This data demonstrates the Koch endocapsular punch to be an effective and safe means for anterior capsulectomy.
