The sides of the ring form a primary plane, and the plates are located in respective planes above and below the primary plane. The outer periphery of the top and bottom plates forms a lip feature which is the opening to the pocket which retains the iris.

  • Patent number: 5722970
    Abstract: Procedures using a laser surgical probe are disclosed in which laser energy can be directed at an angle relative to the longitudinal axis of the probe. In a preferred procedure, the laser probe is inserted into an internal portion of a mammal with a laser light beam being directed into the probe along a longitudinal axis. A reflecting surface on the probe reflects the laser light beam so that the beam exits the probe at an angle relative to the longitudinal axis, thereby directing the laser light onto tissue of the mammal. The tissue contacted by laser light can be viewed during the procedure by looking through the reflecting surface. A particularly preferred procedure comprises an anterior capsulotomy.
