Ultrasonic vitreous cutting tip

Abstract:

An ultrasonic cutting tip has a hollow shaft with a proximal and distal end. The proximal end is configured to be attached to an ultrasonic hand piece, and the distal end has a smooth continuous surface. An opening is located near the distal end of the hollow shaft. The opening is configured to cut vitreous when the cutting tip is vibrated ultrasonically in a torsional manner.
