    Phaco chop minimizes ultrasound time and zonular stress. Chopping is an advanced phaco method that can help surgeons deal with more complicated cases, such as brunescent nuclei, weak zonules, and small pupils. This video presents pearls and strategies for learning phaco chop, based upon the instructors' experience in teaching residents. Multiple edited high-definition videos illustrate both horizontal (Nagahara) and vertical (quick chop) methods of chopping. A stepwise game plan for converting to phaco chop is presented, along with phacodynamics principles for selecting machine parameters and instrumentation. Common errors are illustrated and discussed. This video presents both variations of the phaco chop technique; their respective advantages in complicated cases; the instrumentation, machine parameters, and transition steps involved; and common mistakes.
