  • Patent number: 7143990
    Abstract: An apparatus and method for the production of ophthalmic lenses, and particularly contact lenses, which minimizes damage of the lens in removal from the mold. The ophthalmic lens is produced in a mold having a male part and a female part that are placed in proximate relation to each other to create a lens-forming cavity. At least the female surface of the female part mold is preferably coated with plasma and is irradiated for a predetermined time such that the female surface and/or surface coating is at least partially cured. Once the female surface, and alternately the male surface and other surfaces of the mold, is at least partially cured, a curable lens-forming material is placed into the lens-forming cavity and cured to form an ophthalmic lens.

  • Patent number: 6994386
    Abstract: A gripper (1) for contact lenses comprises a gripper head (10) which has a bearing surface (100) for a contact lens (CL) and in which one or more openings (101, 102) are provided through which an underpressure can be applied in order to suck the contact lens (CL) against the bearing surface (100), and through which an overpressure can be applied in order to release the contact lens (CL) from the bearing surface (100). Channels (103) are provided in the bearing surface (100) and connect a plurality of openings (101, 102) to one another.
