Claim:
1. A system for performing an ocular surgical procedure, comprising: a multiple frequency signal source; a configurable tuned output filter connected to the multiple frequency signal source; and a multiple frequency ultrasonic handpiece, wherein the multiple frequency signal source operates at a first output frequency configured to drive the configurable tuned output filter and the multiple frequency ultrasonic handpiece at the first output frequency; the multiple frequency signal source operates at a second output frequency configured to drive the configurable tuned output filter and the multiple frequency ultrasonic handpiece at the second output frequency; the configurable tuned output filter is switchable to selectively match the first output frequency and the second output frequency, wherein the configurable tuned output filter substantially passes the first output frequency and substantially attenuates the second output frequency when switched to match the first output frequency, and substantially passes the second output frequency and substantially attenuates the first output frequency when switched to match the second output frequency; and the configurable tuned output filter is configured to minimize third harmonic frequency and/or higher harmonic frequency effects for the multiple frequency ultrasonic handpiece.
