Abstract:
Phacoemulsification apparatus includes a handpiece having a needle and electrical apparatus for ultrasonically vibrating the needle. A power source provides electrical power to the handpiece electrical apparatus and irrigation fluid is provided to the handpiece needle and aspirated therefrom during phacoemulsification. Temperature sensors are provided for determining the temperature of the handpiece needle and a control unit is provided for varying a power level provided to the handpiece electrical apparatus and the power source in response to the needle temperature. Alternatively, the control unit functions to vary either irrigation fluid flow or aspiration fluid flow from the handpiece in response to the needle temperature.
