Abstract
We describe a micropunch for removing a round piece of anterior capsule (with a diameter of 500 microns) and a technique to prevent enlargement of the linear anterior capsulotomy by tearing in endointeracpsular cataract surgery. The anterior capsule at both capsulotomy ends is excised by the micropunch, and the resulting continuous, round, smooth-edged margin prevents tearing due to reduced concentration of stress.
摘要
我们描述了一种用于切除圆形前囊片（直径500微米）的微型打孔器以及一种在囊内白内障手术中防止线性前囊切开术因撕裂而扩大的技术。微型打孔器切除前囊切开术两端的前囊，由此产生的连续、圆形、边缘光滑的边缘可防止因应力集中降低而导致的撕裂。
