Abstract
An enzymatic intralenticular cataract treatment for removal of nuclear cortical and subcapsular regions of the cataractous lens through enzymatic digestion thereof which comprises introduction of a concentrated solution of a trypsin enzyme into the nuclear and cortical regions of a cataractous lens, and after enzymatic digestion removing the liquefied cataractous material. The procedure allows subsequent removal of the nuclear, cortical and subcapsular portions of a cataractous lens through a very tiny incision in the eye and lens capsule, leaving all other structures within the eye intact. Bovine and porcine trypsins are preferred.
