ABSTRACT:
Surgical system for phacoemulsification providing infusion fluid apparatus and aspiration or evacuation apparatus to supplement the action of ultrasound vibrational energy applied to the surgical target area via a surgical handpiece. The supplemental apparatus for infusion and aspiration maintains a stable control volume within the anterior chamber of the human eye during a phacoemulsification procedure. Integration of the fluid pressure and flow sensors in a close proximity of less than 8 inches with the surgical handpieceand reduction of communicating fluid pressure and flow rate via fluid conduits allows fast system response time and accurate operation control.
