Abstract
Phacoemulsification apparatus includes a phacoemulsification handpiece having a needle and an electrical circuitry for ultrasonic vibrating the needle. A power source provides pulsed electrical power to the handpiece electrical circuitry and an input is provided for enabling a surgeon to select an amplitude of dislighted pulses and a pulse width. A control system and pulse duty cycle is provided for controlling the off duty cycle to insure heat dissipation before a subsequent pulse is activated, including a foot pedal switch.
