Abstract
An aspiration/irrigation tip adapted for use with a handpiece for the removal of a cataractous lens from the eye is described. The tip, which may be used with an ultrasonic handpiece, is a bent, hollow-bore needle. The shaft of the needle is bent to form a distal invasive portion and a proximal non-invasive portion which attaches to the handpiece. The angle in the shaft enables the surgeon to hold the handpiece at an ergonomically preferred angle with respect to the eye while performing phacoemulsification. Heating of non-target tissues such as the cornea due to friction between the non-target tissue and the vibrating needle is reduced.
