[Theory and surgical technic of capsulorhexis].

Kapsulorhexis is a surgical technique for opening the anterior lens capsule with a circular, smooth-edged and continuous margin. Basically, the technique consists of a precisely controlled continuous capsular tear (rhexis), using only a sharp disposable needle with a bent tip. The method is reproducible, requires minimal instrumentation, is compatible with all current techniques of extracapsular surgery, and can be learned at no risk.
