  • Method of making an intraocular lens with fracture resistant haptics
    Patent number: 5895610
    Abstract: The polymethyl methacrylate (PMMA) or copolymer thereof used to produce one-piece intraocular lenses is modified by a compression molding process to produce a much tougher material with improved mechanical properties. The process takes material in rod form and compresses into lens blanks. The molded lens blanks receive little or no compression strain in the center 4 mm optic zone. The compression is limited to the periphery region outside the center 4 mm zone. The intraocular lens fabricated from the molded lens blank exhibits greatly increased haptic mechanical properties and resistance to breakage.
    Type: Grant
    Filed: September 30, 1997
    Date of Patent: April 20, 1999
    Assignee: Iolab Corporation
    Inventors: Shiao H. Chang, Charles H. Sherwood, Bruce A. Tunberg, Paul D. Rice, Walker L. Gordy

  • Gauge for calibrating surgical scalpel
    Patent number: 4815218
    Abstract: A surgical scalpel having an extendable blade, said blade being extended by rotating a movable portion of a barrel with respect to a fixed barrel portion, the initial extension being done at a fast rate and the final extension or depth adjustment being done at a slow rate. Additionally, the invention includes a gauge in combination with the scalpel for calibrating blade depth, the gauge consisting of a base, a slidable block with a tapered ridge and width markings and a slidable support for the scalpel, so that the scalpel can be abutted with the block for measurement and backed off for block adjustment.
