Method of making artificial intraocular lenses Patent #: 4012823
AbstractAn artificial intraocular lens implant for the anterior chamber of the eye after crystalline extraction is disclosed. The prosthetic lens includes a substantially light transparent disc having a central optical zone bounded at the rear thereof by three affixment points for three U-shaped loops of Nylon 66 or polypropylene material. The loops are arranged in a Y-shaped configuration such that two of the free legs, one from each adjacent loop, are connected at each affixment point, with the closed ends projecting outwardly and away from the plane of the disc. Additionally, a fourth U-shaped loop is affixed to the edge of the disc and projects away therefrom in a plane substantially parallel to that of the disc. The fourth loop is in substantial vertical alignment with one of the other three loops.
