  • YAG compatible posterior chamber intraocular implant
    Patent number: 5013322
    Abstract: A posterior chamber ocular implant compatible with treating secondary cataracts by means of a YAG laser beam. A lens (1) has two convex faces (1a, 1b) and spacer members (10) for spacing the posterior capsule away from the posterior face (1b) of the lens. The spacer members project from the bases (11) of the haptics (2) used for fixing the lens in the eye. The lens makes it possible to treat possible secondary cataracts using a YAG laser without running the danger of marking the implant.
