  • Patent number: 6146405
    Abstract: An ophthalmic applanator for treatment of corneal lamellar flaps/caps includes a disc having a concave bottom surface with a curvature flatter than the curvature of the external surface of the cornea of the eye and steeper than the curvature of the surface of the sclera of an eye and a concave or convex top surface. The radius of curvature of the bottom surface produces a radiating pressure of higher magnitude centrally than peripherally, but is also curved sufficiently to minimize the risk of excessive indentation of the cornea. The convex or concave upper surface reduces reflection from the operating microscope.
