영문 초록

Purpose: To compare surgically induced astigmatism and influences on the corneal endothelium in phacoemulsification by Ozil^{Ⓡ and Hyperpulse mode of InfinitiⓇ using 2 different corneal incision lengths of 2.2 mm and 2.8 mm. Methods: The patients were grouped by the mode of phacoemulsification and incision size as follows: OzilⓇ mode with 2.2 mm incision group (n = 29), and 2.8 mm incision group (n = 30); Hyperpulse mode with 2.2 mm incision group (n = 29), and 2.8 mm incision group (n = 30). The surgically induced astigmatism, central corneal thickness and endothelial cell density were measured up to 2 months after surgery and the efficiency of 2 modes compared by measuring average phacoemulsification times. Results: There was no significant difference in the surgically induced astigmatism, central corneal thickness, endothelial cell density, best corrected visual acuity and average phaco power among 4 groups. The cumulated dissipated energy (CDE) using OzilⓇ mode was lower than Hyperpulse mode in the group of nuclear sclerosis grade 1 and 2. Conclusions: Two different modes of phacoemulsification using OzilⓇ and Hyperpulse mode, and different incision sizes of 2.2 mm and 2.8 mm in InfinitiⓇ showed no significant difference in the endothelial cell density or the surgically induced astigmatism up to 2 months after surgery. Phacoemulsification using OzilⓇ mode is considered more efficient in low grade nuclear sclerosis cataract.}
