    摘要: A handpiece having at least one 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.

    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 system and method for non-invasive pressure sensing are disclosed. One embodiment of the system is an assembly comprising: a plurality of coherent light sources, wherein the plurality of coherent light sources are located in a fixed relationship to one another; an image sensor; and a pressure chamber, comprising a flexible diaphragm, the flexible diaphragm configured to flex in response to a change in pressure in the pressure chamber and operable to reflect a beam of light originating from each of the plurality of coherent light sources onto the image sensor. The pressure sensing assembly can further comprise a processing module operably coupled to the plurality of coherent light sources and to the image sensor and a memory operably coupled to the processing module, wherein the memory includes operational instructions that cause the processing module to carry out the steps of an embodiment of the method for non-invasive pressure sensing of this invention. Such a method can comprise the steps of: directing the plurality of coherent light beams, at a known incidence angle, onto the flexible diaphragm, wherein the plurality of coherent light beams form a pattern of light spots on the diaphragm; capturing at the image sensor an image of the light spot pattern reflected from the diaphragm, wherein the light spot pattern is indicative of the pressure within the pressure chamber; and determining the pressure within the pressure chamber from the captured light spot pattern of the image. The pressure sensing assembly can further comprise a fluidics interface operably coupled to the processor for receiving instructions from the processor to control fluid flow in a fluidics system coupled to the pressure chamber. Such a fluidics interface could be, for example, part of a surgical system, such as an ophthalmic surgical system, incorporating an embodiment of the present invention. The pressure sensing assembly can also comprise a calibration interface for providing calibration inputs to the processor.
