A method for controlling aspiration and irrigation fluids in an eye during a surgical procedure includes placing a handpiece in an operative relationship with an eye for introducing irrigation fluid and aspiration of fluid from the eye. Irrigation is provided at diverse pressures and aspiration is controlled on the basis of vacuum levels sensed in the handpiece corresponding to an occluded condition of the handpiece. Additionally, during phacoemulsification procedures, ultrasonic power provided to the handpiece may by varied in response to the vacuum levels corresponding to an occluded condition of the handpiece. Apparatus for performing the method of the invention is also provided.
