METHOD FOR CONTROLLING PHACOEMULSIFICATION SYSTEM AND PHACOEMULSIFICATION APPARATUS

摘要

PPROBLEM TO BE SOLVED: To provide a method for controlling a phacoemulsification system and a phacoemulsification apparatus which enable controlling ultrasonic power responsive to necessities of both a method of an operation and special technique when a phacoemulsification operation is performed. PSOLUTION: The phacoemulsification apparatus comprises: a phacoemulsification handpiece 30; a means 32 for supplying irrigation fluid to the handpiece; a variable speed pump 14 connected in fluid communication with the handpiece for aspirating irrigation fluid from the handpiece by vacuum; a power source 16 for supplying ultrasonic power to the handpiece; a sensor 24 connected in fluid communication with the handpiece for sensing vacuum levels in the handpiece; and a control unit 12, responsive to the sensed vacuum levels in the handpiece, for varying the ultrasonic power level supplied to the handpiece by the power source.
