ABSTRACT:
An apparatus for cleaning and sterilizing soft contact lenses comprises a disinfection unit and a control unit. The disinfection unit comprises a receptacle for selectively containing a cleaning liquid and a sterilizing liquid, and a lens holder having perforate lens compartments. The lens holder is removably mounted in the receptacle and rotatable therein. The rotation of the lens holder effects enhanced cleansing action by turbulent flow of the cleaning liquid over the lenses. A heater is preferably mounted on the control unit in intimate heat transfer relation with the disinfection unit when the units are secured together (e.g. with permanent magnets) for heating the sterilizing liquid in the receptacle. The control unit controls the heater for providing alternating high temperature periods (not greater than about 60.degree. C.) and lower temperature periods for sterilizing the cleaned lenses.
