“Stop & drop”- a modified “stop & chop” phacoemulsification technique for cataract surgery

Abstract

Purpose To introduce a novel technique termed “stop and drop” for creating the first crack in the initial hemi-nucleus, eliminating the need to slip a chopper under the anterior capsular rim during horizontal chopping, hence lowering the risk of capsular or zonular damage. Methods Placing a blunt chopper tip on the upper surface of the hemisection proximal to the capsular edge and pressing it downward to initiate a crack in a pinching manoeuvre. Once a crack has formed, the chopper can slide to the side, widening the crack and assisting the phaco needle to pull out the first fragment. Results The technique was used in over 100 cases of cataracts successfully. No radial tear, posterior capsule rupture or zonulolysis occurred. Conclusions “Stop and drop” is an effective and safe technique for performing phacoemulsification. It is not suitable for soft nuclei where the chopper will likely “cheese-wire” through the nuclear material.
