Zonulysin

Zonulysin

A brand name for the protein-splitting enzyme alpha-chymotrypsin that was made up in a solution for the purposes of dissolving the ZONULE as a preliminary to the now-obsolete INTRACAPSULAR method of removal of a cataractous lens. This technique is now rarely used in developed countries.
