  • Pulsed ultrasound method for fragmenting/emulsifying and removing cataractous lenses
    Patent number: 6083192
    Abstract: A method and apparatus for removing cataracts in which a flexible line preferably is inserted through an incision into the anterior chamber until its end is adjacent the cataract. Ultrasonic energy, preferably up to 100 Mhz, is coupled to the cataract by an optical fiber in the line. An irrigation sleeve provided about the optical fiber and an aspiration sleeve extending partially around the irrigation sleeve conduct irrigating liquid to and remove the fragmented/emulsified material from the anterior chamber and form with the fiber the flexible line.
    Type: Grant
    Filed: February 14, 1997
    Date of Patent: July 4, 2000
    Inventor: Patricia E. Bath
  • Laser apparatus for surgery of cataractous lenses
    Patent number: 5919186
    Abstract: A method and apparatus for removing cataracts in which a flexible line preferably 1 mm or less in diameter is inserted through an incision into the anterior chamber until its end is adjacent the cataract. Coherent radiation, preferably at a frequency between 193 and 351 nm, is coupled to the cataract by an optical fiber in the line. An irrigation sleeve provided about the fiber and an aspiration sleeve extending partially around the irrigation sleeve conduct irrigating liquid to and remove ablated material from the anterior chamber and form with the optical fiber the flexible line.
