ABSTRACT:
A method and apparatus for phacoemulsification in which handpiece occlusion is sensed by a vacuum rise beyond a programmable level. The speed of a variable speed peristaltic pump is varied in response to the sensed handpiece occlusion condition. Ultrasonic phaco power can be adjusted in response to the sensed handpiece occlusion condition. The adjustment of the ultrasonic phaco power can be performed separately or in addition to the variation of peristaltic pump speed. In addition, the ultrasonic pulse duty cycles can be varied in response to preset ultrasonic power levels.
