For a resident surgeon, the stop-and-chop technique serves as the essential bridge between basic sculpting and advanced nuclear disassembly. It begins with a traditional central groove, providing the safety and visibility of a “stop” or trench. This familiar step creates the space needed to safely place a chopper and split the nucleus into two halves. By mastering this, the resident learns the mechanical vectors of a crack without the high-stress environment of an undivided nucleus. Once the new surgeons are comfortable with these maneuvers, they should transition to phaco chop. This advanced method eliminates the time-consuming and energy-intensive sculpting phase. By using the chopper to directly cleave the nucleus, the surgeon significantly reduces total ultrasound energy and minimizes stress on the zonules. Mastering phaco chop is the hallmark of an efficient, high-volume surgeon, offering superior safety in cases with dense nuclei or weak capsular support. This resident is ready to move to phaco chop!
