  • Device for use in eye surgery
    Patent number: 8945213
    Abstract: A sealing device for use inside a capsular bag after the natural lens has been removed has a plug part adapted to seal a rhexis in a capsular bag, thus preventing displacement through the rhexis of a lens-forming liquid material injected through the rhexis and adapted to replace the natural lens and form an intraocular lens implant. The plug part has a slightly larger area than the capsulorhexis and is made of a deformable polymer. The sealing device further has a removable adjuster connected to the plug part, the adjuster protruding anteriorly from an outer surface of the plug part and being capable of positioning the plug part to a desired location.
    Type: Grant

  • Enhancement of lens regeneration using materials comprising polysiloxane polymers
    Patent number: 7794697
    Abstract: The present invention addresses the treatment of ocular conditions by the enhancement of lens regeneration. Enhancement of lens regeneration is accomplished by the administration of a composition comprising a polysiloxane polymer having functional acryl groups useful in the preparation of intraocular lenses (IOLs).
