Abstract

The most common and effective surgical technique for cataract extraction is PHACOEMULSIFICATION. One of proposed mechanisms of PHACOEMULSIFICATION is the direct mechanical effect named jackhammer theory. Close mechanical contact between the tip and the nucleus is one of important factors which determine the efficacy of jackhammer effect.Clockwise turning of stainless steel screw, slightly larger than the inside diameter of a standard phaco tip 1 mm behind the tip boarder, causes internal clockwise grooves. On the external surface, one row of counterclockwise grooves with 1 mm in length was made.The designed tip in vitro and immersed in salin solution was examined to evaluate the efficiency of emulsifying chestnut particles and mature human lens. In vitro effective phaco time (EPT) was less for the double-threaded tip compared with internally grooved tip. The anti-directional design of internal and external grooves could improve mechanical adherence. Important consideration with this design is the fact that these grooves create more cavitation.This tip seems useful especially for stony hard nuclei. Future in vivo and clinical studies are needed to better discover features of this design.
