Abstract

Abstract An aqueous anti-microbial disinfectant solution for contact lenses contains an effective amount of an active ingredient which is an anti-microbial, organosilicon quaternary ammonium salt chemically bonded to a water soluble, high molecular weight organic polymer. The solution is non-toxic and non-irritating to the eye, and does not adsorb or penetrate into a contact lens.
