摘要： A system and method for performing a femto-fragmentation procedure on tissue in the crystalline lens of an eye requires that a laser beam be directed and focused to a focal point in the crystalline lens of the eye. The focal point is then guided, relative to an axis defined by the eye, to create a segment cluster by causing Laser Induced Optical Breakdown (LIOB) of tissue in the crystalline lens. The resultant segment cluster includes a plurality of contiguous, elongated segments in the crystalline lens that are individually tapered from an anterior end-area to a posterior end-area. Specifically, this is done to facilitate the removal of individual segments from the segment cluster in the crystalline lens.

摘要： A phacoemulsification needle includes a hub for connection to an ultrasonic handpiece. An elongated shaft is formed with the hub and extends from the hub. A distal end of the shaft breaks-up tissue when the distal end is caused to be vibrated by the handpiece. At least a distal portion of the shaft is formed of a material that has properties providing advantages compared to a metal needle. Example properties include a substantially lower density, a substantially higher electrical resistivity, a substantially lower thermal conductivity, a substantially lower mechanical lateral stiffness, a substantially higher efficiency of converting electrical energy powering the handpiece into motion of the distal end, a substantially lower acoustical impedance, a substantially higher Poisson's ratio, and a substantially higher mechanical gain.

摘要： A phacoemulsification transducer assembly includes a reflector and a driver connected to the reflector. The driver has a known driver vibration frequency range. A horn is connected to the driver opposite the reflector. A needle is connected to the horn opposite the driver. The needle has a known free shaft length. To maximize a desired stroke length of the needle for a minimal amount of power applied to the driver, a material forming the needle is chosen such that a speed of sound through the material results in a quarter-wavelength distance at the driver vibration frequency range substantially equal to the needle free shaft length.

摘要： An ophthalmic surgical device includes a housing having a distal end and a proximal end. A cannula is attached to the housing distal end and has a distal tip with at least one port in communication with a lumen extending through the cannula and in communication with an aspiration path in the housing. A vibration source is held within the housing for vibrating the distal tip of the cannula for assisting in vitreous and other tissue removal from a patient's eye. The vibration source creates a peak velocity of the distal tip equal to or less than a potential maximum flow velocity of water through the at least one port for a pressure differential between an intraocular pressure of the eye and a pressure within the cannula lumen that is less than the intraocular pressure.
