capsulorhexis 

A form of capsulotomy in which the incision of the anterior capsule is made in a smooth circular pattern along the periphery of the lens to enable removal of opaque lens material during extracapsular cataract extraction. It is the preferred method of capsulotomy when inserting a rigid intraocular lens because the incision is less likely to tear than that made by the 'can-opener' technique.
