Techniques of nuclear delivery in Manual small incision cataract surgery
Manual small incision cataract surgery (MSICS) is now practiced in both developed and developing countries. It involves the extraction of a complete or divided nucleus from the capsular bag through the capsular opening and then through the sclero-corneal tunnel. A number of techniques of nuclear delivery have evolved over the time. These techniques have their own merits and demerits. However they give similar results in the hands of experienced surgeons. The methods are broadly classified as follows: Anterior chamber maintainer technique Microvectis technique Phacofracture technique Phacosandwich technique Fish hook technique Ruit's technique We shall now discuss the difference in steps involved in the various techniques. 1. Anterior Chamber Maintainer technique ( Blumenthal`s technique): Fixing the AC Maintainer (Anterior Chamber Maintainer) After the tunnel has been dissected with a crescent knife, two side ports are made with 19 or 20 G MVR knife, one for capsulotomy and the other f
