Abstract

Objective: To assess the efficacy and safety of a modified double extra sharp chopper for removal of hard cataracts. Design: Prospective non-comparative interventional clinical study. Participants: Forty eyes from 25 patients with hard mature cataract grades 3-4. Methods: The pre-modified Koch chopper was sharpened under the slit lamp to become extra sharp at the tip and inside the edge and 2 mm in length. Patients with hard mature cataract grades 3-4 (grade 4 being the hardest) underwent phacoemulsification by single surgery and were analyzed prospectively. Results: The mean effective phaco time was 23.73 ± 5.75 seconds. Minimal power was facilitated by using horizontal chopping using a self-made double extra sharp chopper. No resistance was encountered while moving the chopper, regardless of cataract persistency. Preoperative BCVA were count fingers (47%), hand movement (35%), and light perception (18%). Postoperative BCVA on day 1and day 7 were 0.57 and 0.95, respectively. There was no difference of effective phaco time among nuclear hardness (P = 0.467), which represent the effectiveness of the extra sharp chopper. Conclusions: The double extra sharp chopper facilitated a safe and rapid visual rehabilitation and maximal subject comfort when doing phacoemulsification for hard mature cataracts.
