Abstract:
The present invention comprises a method of operating an ophthalmic surgical hand piece, providing a series of power pulses to the hand piece, each of the series of power pulses having a first portion that produces torsional movement of a cutting tip and a second portion that produces longitudinal movement of the cutting tip; measuring vacuum pressure; altering the duration of the first portion as vacuum pressure increases; and altering the duration of the second portion as vacuum pressure increases.
