Abstract

• We describe a micropunch for removing a round piece of anterior capsule (with a diameter of 500 μm) and a technique to prevent enlargement of the linear anterior capsulotomy by tearing in endointercapsular 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.
