摘要： A method employing 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. When in torsional mode, material may clog the cutting tip. The present method includes the step of providing a pulse of longitudinal movement of the tip when clogging is detected.

摘要： A surge-flow regulator (36) for use with an ophthalmic surgical instrument (12) having an infusion line (20) adapted to irrigate a surgical site with fluid and an aspiration line (24) adapted to carry the fluid and particles of lenticular debris away from the surgical site. The surge-flow regulator (36) includes a flow limiting device (40) that is placed in fluid communication with the aspiration line (24) to control surge-flow of the aspirated fluid and lenticular debris through the aspiration line (24). The lenticular debris carried in the aspiration line (24) is processed into smaller particles before the fluid and debris are introduced to the flow limiting device (40).

摘要： An improved endocapsular tension ring and method of implanting same in a capsular bag of a human eye. The improved endocapsular tension ring is particularly adapted to provide long-term stabilization and centralization of the capsular bag during and after intraocular surgery in patients having missing or damaged zonules. In one aspect of the invention, the improved endocapsular tension ring includes an open-ended loop formed of biocompatible material that is constructed to be resilient to compression in the radial direction within the capsular bag to prevent shrinkage of the capsular bag during and after intraocular surgery. The improved endocapsular tension ring includes a fixation element joined to the open-ended loop that is adapted to be attached to the scleral wall of the eye and thereby stabilize and centralize the capsular bag within the posterior chamber of the eye without passing sutures through the capsular bag. Methods for implanting the improved endocapsular tension ring in the capsular bag of a human eye are also disclosed.
