    摘要: Improved intraocular irrigating solutions are described comprising a cellulose derivative such as hydroxypropylmethylcellulose. In addition, certain solutions of the present invention comprise glutathione and dextrose. The solutions have enhanced viscosities that reduce the risk of damage to intraocular tissues during intraocular surgical procedures by reducing the turbulence of the solutions and dampening the movement of tissue fragments and air bubbles. The solutions preferably also have modified surface tensions that more closely resemble the surface tension of the aqueous humor.

    摘要: A phacoemulsification tip having a distal end that is longer in the vertical direction than it is in the horizontal direction. When vibrated ultrasonically, such a shape causes the distal end of the phacoemulsification tip to have a slicing or chopping action as opposed to a more traditional emulsification action.

    摘要: A flexible ring having a diameter suitable for an anterior chamber rhexis. Imbedded in the ring is a heating element or filament. Alternatively, the ring may contain a pair of adjacent, circular electrodes. The electrodes or heating filament are placed against the anterior capsule and electrical current is applied, causes localized heating around the electrodes or filament. The flexible nature of the ring and electrodes allow the ring to be folded so as to pass through a relatively small (

    摘要: A handpiece having a single set of piezoelectric elements polarized to produce longitudinal motion when excited at the relevant resonant frequency. The piezoelectric crystals are connected to an ultrasonic horn to which a cutting tip is attached. The horn and/or the cutting tip contains a plurality of diagonal slits or grooves. The slits or grooves produce optimized torsional movement in the cutting tip when the piezoelectric crystals are excited at a second resonant frequency. Preferably, the two drive frequencies are not coincident, but provided in non-overlapping pulses.

    摘要: A graphical user interface for use in phacoemulsification surgical systems that allows a user to select different pulse modes by touching portions of the display screen. The user interface includes first and second display elements. One display element includes a representation of the on-time of the pulses, and the other display element includes a representation of the off-time. The representations show how the on-time and off-time change relative to a position of a controller, such as a foot pedal. The representation show a constant time, or that a time increases or decreases as the foot pedal is pressed. To select a pulse mode, a user can scroll through different pulse representations by touching the screen at the display elements. The selected pulse mode can be continuous, pulse, burst, or a combination or derivation thereof.
