  • Surgical handpiece tip
    Patent number: 6156036
    Abstract: A surgical handpiece tip with at least two coaxially spaced electrically conductive tubes. The tubes are separated by an electrical insulator. The interior of the inner tube is used for aspiration of liquefied tissue. The distal portion of the interior tube terminates just inside of the outer tube so as to form a boiling region. Electrical current is passed between the inner and outer tube to rapidly boil any surgical fluid in the boiling region. The boiling fluid rapidly expands out of the ring between the tubes and contacts the targeted tissue, thereby liquefying the tissue and allowing the tissue to be aspirated.

  • Use of borate-polyol complexes in ophthalmic compositions
    Patent number: 6143799
    Abstract: Water-soluble borate-polyol complexes are useful as buffers and/or antimicrobials in aqueous ophthalmic compositions, including those containing polyvinyl alcohol. These compositions have greater antimicrobial activity than comparable compositions containing typical borate buffers and unexpectedly increase the antimicrobial efficacy of other antimicrobial agents when used in combination. In addition, use of the borate-polyol complexes avoids the incompatibility problem typically associated with the combination of borate buffer and polyvinyl alcohol; therefore, the compositions disclosed herein may also contain polyvinyl alcohol.

  • Asymmetric intraocular lens injection cartridge
    Patent number: 6143001
    Abstract: A lens injector cartridge having an asymmetric bore. The asymmetric bore initiates the folding of the lens on one side only, thereby reducing the amount of energy imparted to the lens and the potential for damage to the lens. The gentle folding of the lens also assists in positioning the travel of the haptics down the bore, thereby reducing the potential for damage to the haptics.

  • Liquefaction handpiece
    Patent number: 6110162
    Abstract: A surgical handpiece having at least two lumens mounted to a body. At least one lumen is used for aspiration and at least one other lumen is used to inject heated surgical fluid for liquefying a cataractous lens. A portion of the second lumen is enlarged to form a pumping chamber. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the second lumen. The pumping chamber may use any type of heater, such as a resistive heater or an induction heater. The handpiece may also contain other lumens for injecting relatively cool surgical fluid.

  • Polishing method for soft acrylic articles
    Patent number: 6095901
    Abstract: A method for polishing articles comprising soft acrylic materials is disclosed. The method includes a polishing step and a cleaning step. In the polishing step, a receptacle is charged with polishing beads of various sizes, alumina, a swelling agent and the articles to be polished, and agitated for a period of time and at a speed sufficient to remove surface irregularities. Following the polishing step, the polished articles are cleaned by agitating them with a cleaning slurry comprising cleaning beads of various sizes, alumina, a solvent and a surfactant for a period of time and at a speed sufficient to clean the surface of the polished articles. Agitation is preferably accomplished by a tumbling machine.
