Air bubbles can be reduced or eliminated from the infusion source used during surgical procedures which require the delivery of irrigating fluid to the operating field. This is particularly a problem during surgical procedures performed within a closed organ, such as the eye. A constant low rate of infusion is created upon removal of a test chamber from a surgical handpiece. Pressure within the test chamber is lowered prior to removal of the test chamber.

A tapered infusion sleeve that has an orifice whose exterior margin is either rounded off, beveled, tapered, curved inclined or otherwise forms an angle with an adjacent exterior of the sleeve that is other than ninety degrees and other than substantially ninety degrees. As a result, the exterior margin is less likely to become caught or ensnared when being passed through an incision opening with a surgical instrument.

A flexible sheath is attached to an end of a rigid extension tube. The other end of the rigid extension tube is connected with a surgical handpiece. Two flexible sheaths may be used—one as a barrier against contamination of aspiration tubing and the other as a barrier against contamination of irrigation tubing. This is effected by securing two rigid extension tubes between the surgical handpiece and an associated one of the aspiration and irrigation tubings. Each flexible sheath is collapsible and expandable so they may be expanded from a collapsed condition over the associated aspiration or irrigation tubings and secured in the expanded condition. The aspiration and/or irrigation tubings are connected to a cassette of a surgical pack.

An infusion sleeve of an ultrasonic vibrating needle. The sleeve is collapsible and serrated or scalloped at a distal end. Fluid flows through a passage between the needle and the infusion sleeve in a direction from the proximal end of the sleeve to a distal end of the sleeve. Upon reaching the distal end, the fluid emerges by flowing across valley formations that are between peak formations of the distal end of the infusion sleeve. The peak formations abut the exterior of the incision so that the fluid flow cools tissue at the incision and the needle.

An intraocular lens device that includes an intraocular lens optics that provides at least two powers of magnification one being near vision power and the other being distance vision power. The lens optics has surface modulations that are responsible for providing the near vision power. The zone structure provides an add power of over 6 diopters. The add power indicative of an extent that the near vision focusing power is greater than the distance vision focusing power.

A method and apparatus to operate a surgical instrument in response to a thermal condition being detected that warrants curtailment of further operation. When the thermal condition is reached, command signals are generated that cause a needle of the surgical instrument to either have its vibrational speed slowed, have its vibrational movement stopped, or have it withdrawn from its relative position. The detection is of infrared radiation wavelengths and is carried out with either a thermal imaging device of a thermal recognition device. A corresponding temperature of the detected infrared radiation wavelengths is compared to a critical temperature to determine whether the thermal condition has been reached.

A multi-sleeve handpiece for performing phacoemulsification with a vibratory, ported needle and for cooling an exterior of an incision. The vibratory, ported needle breaks up and aspirates broken eye tissue. The handpiece has at least one inner sleeve that guides irrigation fluid to the eye and/or reduces friction between the vibrating tool and the surrounding rigid sleeve or tissues. The handpiece has an outer, cooling sleeve that is concentric with the inner sleeve and the needle and whose distal end has peak and valley formations. The cooling sleeve is collapsible to engage incision tissue with the peak formations and allow the cooling fluid to flow across the valley formations to cool the tissue via heat transfer.
