  • Patent number: 7250197
    Abstract: Intraocular lenses or contact lenses 20 are placed on a lower spindle 34 and held there by a vacuum in conduit 34. Noble and reactive gases 56, 58 are introduced and a voltage is applied across upper spindle 32 and lower spindle 34 to plasma treat one surface of the lens. The lens is transferred to the other spindle and the process is repeated.

  • Patent number: 6939486
    Abstract: Method and apparatus for molding an IOL comprising first and second mold halves each having an optic forming surface and haptic forming surfaces which together define a mold cavity in the shape of the IOL to be molded therein when the mold halves are assembled together. An injection port is formed and connects to one of said haptic forming surfaces or the optic forming surface wherethrough a polymerizable material is injected into the mold cavity. A venting port is formed and connects to another haptic wherethrough air escapes from the mold cavity as the polymerizable material is injected through the injection port.

  • Publication number: 20030039748
    Abstract: The present invention provides a method for treating a contact lens to provide an optically clear, hydrophilic coating upon the surface of a silicone hydrogel lens by subjecting the surface of the lens to a process comprising plasma treatment, hydration, and heat sterilization that is controlled to result in a silicate-containing film having a mosaic pattern of projecting plates surrounded by fissures when viewing a 50×50 micron square AFM image, wherein the peak-to-valley distances of the fissures are on average between about 100 and 500 angströms and the plate coverage is on average between about 40% to 99%.
