To compare the intraoperative and short term postoperative outcomes of cataract surgery performed with custom pulse mode of OZil(R) and hyperpulse mode of conventional phacoemulsification METHODS: The patients underwent cataract surgery using the OZil(R) custom pulse mode phacoemulsification (Group 1, n=30) or the conventional phaco Hyperpulse mode one (Group 2, n=36) of Infiniti Vision System. Mean ultrasound time, CDE (Cumulated dissipated energy) and total BSS volume were measured during operation. Best corrected visual acuity, central corneal thickness and endothelial cell counts were checked on 1 day, 1 momth, 2 months after surgery. RESULTS: CDE was decreased significantly in group 1 (p<0.05). But, there were no significant differences in two groups of the mean ultrasound time and the BSS volume (p>0.05). At 2 months, the endothelial thickness was 552.94+/-27.95 micrometer in group 1, and 568.00+/-31.22 micrometer in group 2 and the endothelial cell counts was 2683.0+/-235.6 cell/mm2 and 2694.2+/-407.9 cell/mm2, respectatively. There were no significant differences in two groups. CONCLUSIONS: The OZil(R) custom pulse mode phacoemulsification is an effective procedure in cataract surgery as much as the conventional hyperpulse mode phacoemulsification.
