摘要：
The invention relates to systems and methods for controlling vacuum within phacoemulsification systems. The phacoemulsification system may include a handpiece having a needle coupled to a power Source configured to cause the needle to be ultrasonically vibrated during operation, and an aspiration Source. The system includes a footpedal that defines a first position and a second position, and also includes a computer program product operatively coupled to the handpiece and the foot pedal, having a computer usable medium with a sequence of instructions which causes the processor to control power from the power source and vacuum from the aspiration source applied to the handpiece. The process provides a vacuum at a first level to the handpiece when the footpedal is at the first position； provides power to the handpiece when the footpedal is at the second position； and reduces the vacuum to a second level when the footpedal position transitions.
