  • Silicon carbide IR-emitter heating device and method for demolding lenses
    Patent number: 6663801
    Abstract: A method and a device for removing molded soft contact lenses, high-precision intraocular lenses and the like, from the individual molds in which they are produced. Provided is an infra-red radiation or heater device constituted of silicon carbide IR-emitters, and which employs an individual infra-red emitter for each individual mold, to impart a desired thermal gradient.
    Type: Grant
    Filed: April 6, 2001
    Date of Patent: December 16, 2003
    Assignee: Johnson & Johnson Vision Care, Inc.
    Inventors: Stephen C. Pegram, Allan W. Kimble, Leslie A. Voss, Thomas P. Bingaman, Joseph W. Ricard
  • Process of manufacturing contact lenses with measured exposure to oxygen
    Patent number: 6610220
    Abstract: This invention provides a method of manufacturing a contact lens comprising the step of: dosing a contact lens mold comprising optical mold surfaces with an oxygen-sensitive reaction mixture, wherein said optical surfaces of said contact lens mold have between from 0.13×10−9 to 2.6×10−9 moles/cm2 O2 available to interfere with the reaction of said reaction mixture. This invention further provides a method of manufacturing a contact lens comprising the steps of: dosing a contact lens mold comprising optical mold surfaces with a reaction mixture, and sealing said reaction mixture and said optical mold surfaces away from a gaseous environment, wherein said optical surfaces of said contact lens mold were exposed to said gaseous environment comprising greater than 0.5 percent oxygen just prior to said sealing step.
