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. The needle is coupled to a power source configured to cause the needle to be ultrasonically vibrated during operation and an aspiration source. The system further includes a footpedal that defines a first position and a second position. The system also includes a computer program product operatively coupled to the handpiece and the footpedal, the computer program product having a computer-usable medium having a sequence of instructions which, when executed by a processor, causes said processor to execute a process that controls power from the power source and vacuum from the aspiration source applied to the handpiece. The process includes the steps of providing a vacuum at a first level to the handpiece when the footpedal is at the first position； providing power to the handpiece when the footpedal is at the second position； and reducing the vacuum to a second level when the footpedal transitions from the first position to the second position.
