1. A control system for managing power supplied to a phacoemulsification hand piece, the control system comprising:

  • an irrigation pressure sensor for measuring an irrigation pressure;

    a power source for providing ultrasonic power to the hand piece; and

    a controller for controlling the power source;

    wherein the controller calculates a thermal value based on the irrigation pressure and a power level and decreases the power level in proportion to the calculated thermal value when the calculated thermal value exceeds a threshold thermal value.
