  • Patent number: 5144144
    Abstract: A contact lens cleaning and disinfecting system is formed as a compact unit with an upper housing portion containing a UV lamp and a lower base portion containing a cleaning/disinfecting chamber which is filled with saline solution, a lens holder, a turbulence mechanism for inducing turbulence in the fluid, and an electronic control unit for operating the UV lamp and the turbulence mechanism in a single cleaning/disinfecting cycle of comparatively short duration. The lens holder has a pair of lower lens holder portions for the lenses and an upper bracket for shading the lenses from direct UV radiation. The turbulence mechanism is a magnetic pedal, tethered on the end of a flexible spring, which is driven by a magnetic flux generator to create a whirlpool in the fluid which swirls in and around the lens holder portion. Particles, films, and other deposits dislodged from the lenses are carried by the whirlpool above the upper bracket of the lens holder where they are disinfected by the UV radiation.
