Phaco chop is an advanced technique that requires the surgeon to possess a solid understanding of fluidics and power modulation. When chopping, he or she uses the phaco tip to grab and hold the nucleus. The “grab” is accomplished by the phaco needle’s being impaled into the nucleus. The surgeon buries the phaco needle with a quick burst of energy. Next, moving the foot pedal to foot position 2 allows occlusion of the needle and causes vacuum to build. The vacuum will allow the surgeon to hold the nucleus and resist the movement of the chopper.
