Abstract
A thin tip phaco needle is provided including a body having a longitudinal bore for enabling passage of debris from a surgical site, a threaded end for engaging an ultrasonic probe handpiece, and a tip, disposed at a distal end of the body, for cutting tissue. The tip includes a beveled, or stepped, edge having a wide proximal wall and a thin, distal, cutting wall of about half a width of the wide wall. The beveled edge functions to enhance cutting efficiency of the tip and increase force pressure by the tip on tissue such as to decrease ultrasonic energy required to cause the needle to penetrate hard tissue. The needle tip may be angled so as to define a cutting plane having a wide upper arc and a thin lower arc.
