CL/V-19151/A/CGV 1624 MULTI-ELECTRODE CONTACT LENS DISINFECTION AND CLEANING DEVICE AND METHOD THEREFOR A contact lens care device and method for cleaning and disinfecting contact lenses. The invention utilizes both principles of electrophoresis and electrolysis. The device uses a halide-containing electrolytic buffer solution for disinfecting and cleaning. A halogen concentration is generated electrolytically from the halide in the contact lens containing well by the generation of an electrical field between the two electrodes disposed in the well. The field is maintained for a time sufficient to generate a concentration of halogen which can disinfect the lens. The lens is clean electrophoretically at the same time. Then, the conversion of the halide to halogen is reversed to remove the halogen from the contact lens containing well. This is done by generating an electrical field between the well electrodes and another electrode located in a reservoir connected to the well by a narrow channel or inert divider. The elimination of halogen is so complete that the lens does not need to be rinsed before insertion in the eve. The device may include an automatic control means. (Fig. 1)
