Abstract Contact lenses are simultaneously cleaned and disinfected by contacting the lenses with an aqueous system containing an antimicrobial agent and a proteolytic enzyme for a period sufficient to clean and disinfect the lenses. The aqueous solutions have suitable osmotic values which do not substantially inhibit the activity of the antimicrobial agent.
