Abstract
Contact lenses are disinfected in a method including treating the contact lenses with an aqueous system of hydrogen peroxide in the presence of a hydrogen peroxide decomposition catalyst, and heating the system in order to accelerate decomposition of the hydrogen peroxide. In a preferred embodiment of the method, the initial concentration of hydrogen peroxide in the system is approximately 3-4% and the heating promotes decomposition of the hydrogen peroxide to a concentration of 50 parts per million or less within six hours following initial contact of catalyst with the system. The catalytic decomposition can be performed in a conventional lens sterilization vessel which is inserted within a heated receptacle to heat the reaction vessel and the contained sterilization system. The heated receptacle controls the temperature of the inserted vessel and sterilization system within a range of approximately 60.degree.-80.degree. C.
