ABSTRACT:
A method of generating wave forms for a phaco surgical handpiece, with each wave form having a different frequency includes storing a plurality of sets of digital information, each set corresponding to a different specific frequency and selecting a set of digital information in response to an input corresponding to a resonance frequency of said phaco surgical handpiece. Thereafter selected digital information is read in a manner producing a digital output having a corresponding frequency equal to or lower than the frequency corresponding to the selected set of digital information. Subsequently, the digital output is converted into an analog wave form for driving said phaco surgical handpiece.
