  • Patent number: 5556480
    Abstract: A procedure for disinfecting and cleaning contact lenses, including introducing the lenses into a container containing therein an aqueous hydrogen peroxide solution and a destabilizer component therefor, prepared in such a way that enables this component to cause controlled peroxide destabilization from the first instance and to maximize its oxidizing action in order to achieve a more efficient lens disinfection and cleaning. As a final result of the process, there is a hydrogen peroxide degradation that results in levels that allow the transformed solution to be compatible with the eye and to maintain the contact lens cleanliness parameters.
