ABSTRACT:
A handpiece for the phacoemulsification of cataract tissue is provided in accordance with the present invention. The handpiece can be operatively coupled to a phacoemulsification machine to supply the handpiece with irrigation fluid, aspiration suction and ultrasonic energy. The application of irrigation fluid and aspiration suction to the handpiece are preferably controlled with a foot pedal which is operatively coupled to the phacoemulsification machine. The application of ultrasonic energy to the handpiece is controlled by a button, slide tab, knob or the like which is preferably detachably mounted to the main body of the handpiece so that the application of ultrasonic energy can be manually controlled by the surgeon.
