Summary for Patent: 5,120,499
Title: Method and system for asepticizing contact lenses and storing device
Abstract:Light-transmitting contact lenses of Polymethylacrylate, Gas Permeable of Hydrogel materials may be immersed in an aqueous liquid medium contained in a storing and processing device, all of which are substantially transparent to the ultraviolet radiation spectrum. The lenses, liquid medium and storing device are all irradiated with ultraviolet radiation in a preselected frequency range, while simultaneously being subjected to ultrasonic frequency vibrations to thereby cause asepticization of lenses, liquid medium and storing device. The ultraviolet irradiation and ultrasonic vibrations are insufficient to cause detrimental molecular modification to the lenses or storing device, but does cause the formation of oxidation free radicals in the liquid medium. The unique combination of ultraviolet irradiation and ultrasonic vibration in the presence of the liquid medium containing oxidation free radicals cause rapid destruction of all microorganisms associated with the lenses, liquid medium and storing device.
