Abstract

Purpose: : To evaluate the safety and efficacy of the Zero Ultrasound Technique (ZEUS) during cataract surgery.

Methods: : In this study, 91 eyes of 90 cataract patients underwent phacoemulsification using the Zero Ultrasound Technique. The patients were divided into two groups depending on the amount of ultrasonic power (US) used: Z group with 0 US, C group with US used . Each group was divided into three subgroups depending on the amount of nucleous hardness. Corneal endothelial cell density was examined preoperatively, 1 and 6 months postoperatively. The endothelial cell loss was compared between the groups.

Results: : The mean endothelial cell loss 1 and 6 months after surgery was -14.5 ± 11.4% and -12.9 ± 10% in the Z-group and -16.8 ± 15% and -17.3±16.3% in the C-group (P=0.4412). No intraoperative complications were noted.
