Circular tear capsulotomy, or capsulorhexis, is becoming an increasingly popular method of anterior capsulotomy. We describe a new cystotome with a simple tip modification which is useful for performing a circular tear capsulotomy. The cystotome is a 27 gauge disposable device that is similar to a conventional cystotome used for a can-opener-type capsulotomy except for its unique but simple tip modification. The beveled tip is first bent at 90 degrees and then twisted on its main axis so that the beveled cutting edge is parallel (i.e., in the same axis) to the shaft of the cystotome. We also briefly describe its method of use.
环形撕囊术，即连续环形撕囊，正成为一种越来越流行的前囊切开术方法。我们描述了一种新型的晶状体囊刀，其尖端经过简单改良，有助于进行环形撕囊术。该晶状体囊刀是一种27号一次性器械，与用于开罐式囊切开术的传统晶状体囊刀相似，只是其尖端经过独特而简单的改良。先将有斜面的尖端弯曲90度，然后绕其主轴扭转，使有斜面的切割边缘与晶状体囊刀的轴平行（即在同一轴上）。我们还简要描述了其使用方法。
