ABSTRACT:
A method and apparatus for precisely controlling particle movement relative to a phacoemulsification needle tip is provided. The design monitors actual vacuum present and calculates a pulse shape amplitude waveform proportional to the amount of measured vacuum. An increase in vacuum indicates that the handpiece
eedle is becoming occluded by a large particle. The present design determines whether additional power is required to bump or move a large particle away from the needle tip. The present design may employ a control loop that senses and continuously monitors vacuum. The design may dynamically vary the amount of ultrasonic energy delivered to the surgical area in response to the observed actual vacuum, and can actively vary the amount of power delivered to the surgical area based on the size of the particle and the resultant vacuum realized.
