IMPROVED METHODS FOR ENZYMATIC CLEANING AND DISINFECTING CONTACT LENSES ABSTRACT Contact lenses are both cleaned and disinfected in aqueous solutions of proteolytic enzyme in a single- step by heating to a temperature of between 60 and 100°C. The cleaning and disinfecting process which may be con- ducted in one hour or less performs favorably against conventional methods wherein cleaning and disinfecting are conducted separately over a time period of up to twelve hours.
