<p>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 mechanically agitating 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 mechanical agitation promotes decomposition of the hydrogen peroxide to a concentration of 50 parts per million or less within 6 hours following initial contact of the catalyst with the system. The catalytic decomposition can be performed in a conventional lens sterilization vessel (12) which is secured to a drive mechanism (26) for repeated motion of the reaction vessel (12) in order to maintain continuous agitation of the sterilization system (10) therein.</p> |
