  • Automated method and apparatus for hydrating soft contact lenses
    Patent number: 5836323
    Abstract: An automated means for hydrating a molded hydrophilic contact lens is provided in which a first robotic assembly removes a plurality of contact lens molds from a production line carrier, each of the lens molds having a contact lens adhered therein. The first robotic assembly transports the molds to a first staging area where the lens molds are sandwiched between a lens mold carrier and a top chamber plate to form a first hydration carrier. A first rotary transfer device then hands the first hydration carrier to a second robotic assembly which immerses the first hydration carrier in a hydration bath to hydrate the lens and to release the lens from the lens mold. While the lens is immersed in the hydration bath, each lens is transferred from its respective mold to a lens transfer means found within the top chamber plate.
