Abstract
A method for tuning a phacoemulsification probe during a procedure for treating an eye. The method includes vibrating a piezoelectric actuator of the phacoemulsification probe, by applying to the piezoelectric actuator a tuning signal that (i) covers an operational bandwidth of the phacoemulsification probe and (ii) has an initial power level that is lower than a normal power level set for treating the eye. The tuning signal is measured during an initial signal tuning session. An operating frequency for the phacoemulsification probe is derived from the measured tuning signal. A driving signal, having the normal power level and the derived operating frequency, is applied to the piezoelectric actuator.
