Abstract
A phacoemulsification system includes a phacoemulsification probe and one or more signal generators. The phacoemulsification probe includes (i) a piezoelectric actuator, (ii) a segmented electrode, including multiple electrode segments attached to respective angular sections of a face of the piezoelectric actuator, (iii) a common ground electrode attached to the piezoelectric actuator, and (iv) a needle configured to be inserted into a lens capsule of an eye and to be vibrated by the piezoelectric actuator. The one or more signal generators are configured to vibrate the piezoelectric actuator by applying multiple drive signals between the multiple respective electrode segments and the common ground electrode.
