After a space (trench or crater) is created in the center, the phaco probe is buried at 6 o’clock to produce a vacuum seal, resulting in an effective hold on the nucleus. The chopper is placed close to the phaco probe, which remains steady throughout. The vertical element of the chopper is depressed posteriorly to produce an initial crack. The chopper is repositioned in the depths of the crack and pushed laterally for complete separation. The complete division of the bottom plate is accomplished in step-by-step fashion by repeated lateral movements of the chopper at different sites along the length of the trench/crater, while the phaco probe continues to hold the nucleus at 6 o’clock. This stepwise division eliminates stress on the capsular bag. Similar maneuvers are repeated to create multiple small lens fragments. © Williams & Wilkins 1998. All Rights Reserved.
