Abstract
An improved tip for use with a device for disintegrating tissue located in a predominantly liquid environment. The tip is connected to an oscillation generator, which results in ultrasonic oscillating movement along the tip axis. When placed within the posterior capsule of an eye, the tip causes the tissue of the natural lens in close proximity to disintegrate. The tip has an elongated curved portion having a convex front surface, a concave rear surface and a rear-facing end surface. The elongated curve of the tip and the rear facing end surface allow easy access to all areas of the capsular bag, some of which were relatively unreachable with known ultrasonic tips.
