This video features a combination phaco chop (a combination of vertical chop and horizontal chop techniques) where we play the same video clip at regular speed, then at half-speed, and finally at quarter-speed. By watching it again in slow motion we are better able to show the nuances which allow this technique to be so efficient. Once you realize that you can chop a nucleus into two halves with minimal ultrasound energy in just a second or two, you may not want to go back to divide-and-conquer (which is less efficient, requires more ultrasound energy, and is slower).

Dear professor
In the buzzing phase, do you apply power or just with aspiration?
buzz means to apply phaco energy briefly (foot pedal position 3)
