Abstract: In certain embodiments, a surgical handpiece system includes a phacoemulsification tip, a fluid management system, an ultrasonic drive system, and a controller. The phacoemulsification tip is attached to a shaft. The fluid management system is configured to manage inflow and outflow of fluid from an ocular surgical site. The ultrasonic drive system is configured to generate torsional and longitudinal vibrations in the phacoemulsification tip. The controller is configured to analyze applied voltage and current to the ultrasonic drive system using Fast Fourier Transforms (FFTs), and tune applied frequencies of the torsional and longitudinal vibrations according to at least one resonant frequency.
