미세각막절개 양손 백내장 수술과 고전적 백내장 수술의 비교

Comparison Between Bimanual Microincisional Cataract Surgery and Conventional Coaxial Phacoemulsification

Purpose: To evaluate corneal endothelial cell changes after conventional coaxial phacoemulsification and bimanual microincision cataract surgery (MICS). Methods: Forty patients were divided into 2 groups, coaxial phacoemulsification (Group 1, n=20), and MICS (Group 2, n=20). To evaluate corneal endothelial cell changes after coaxial phacoemulsification and bimanual MICS, intraoperative phacoemulsification power and volume of intraoperative irrigation solution (balanced salt solution, BSS®, Alcon, U.S.A) were measured. Central corneal thickness and endothelial cell count were also evaluated, preoperatively and at 1 week, and 2 months postoperatively. Results: Between the 2 groups, there was no statistically significant difference in intraoperative phacoemulsification power and volume of intraoperative irrigation solution (balanced salt solution, BSS®, Alcon, U.S.A.) (p＞0.05). In addition, there was no statistically significant difference between the 2 groups in endothelial cell count and central corneal thickness (p＞0.05). Conclusions: When comparing bimanual MICS and conventional coaxial phacoemulsification, bimanual MICS appears to have similar endothelial cell changes. In conclusion, MICS has the same safety as compared to coaxial phacoemulsification. J Korean Ophthalmol Soc 2009;50(4):537-541
