Abstract

We aim to demonstrates an efficient, safe and new device Trishool the triple edge wedge tool designed with the principle of classical simple machine to crack and break the mature hard cataract into full thickness free segments . Here edges of the trishool enables us to use the device with right or left hand for multi directional move. A triangular wedge design is incorporated into the tip of the trishool in which pointed apex of wedge is kept at the inner edge of the tip while wide and flat base of wedge is placed at the posterior surface of the tip. Simply drawing the wedge inner edge of the trishool through the equator of the nucleus after hooking it around generate transversal fracture force with amplification, induce full thickness nuclear crack breaking it into two complete free segments.
