ABSTRACT:
A control system for managing power supplied to a phacoemulsification hand piece includes a power source that provides power to the hand piece and a controller that controls the power source. The controller calculates a thermal value based on irrigation fluid flow 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. Irrigation fluid flow can be calculated from irrigation fluid pressure.
