초록

목적: OZil® mode를 이용한 수정체유화술 후 임상결과를 hyperpulse mode와 비교한다.
대상과 방법: Infiniti Vision System 중 OZil®의 custom pulse mode와 conventional phaco의 hyperpulse mode를 이용하여 21명(30안)은 OZil® mode (1군)로 27명(36안)은 hyperpulse mode (2군)로 백내장수술을 시행하였다. 평균 초음파사용시간, CDE (Cumulated dissipated energy), 총 평형염액, 수술 후 1일, 1달, 2달째에 교정시력, 각막두께, 각막내피세포수를 비교하였다.
결과: CDE는 1군에서 통계적으로 유의하게 작았으나, 평균 초음파사용시간, 사용된 평형용액량은 두 군간 차이는 없었다. 각막두께는 수술 후 2달째 552.94±27.95 μm, 568.00±31.22 μm, 각막내피세포수는 2683.0±235.6 cell/mm2, 2694.2±407.9 cell/mm²로 두 군간에 유의한 차이는 없었다.
결론: OZil® mode을 이용한 수정체유화술은 hyperpulse mode와 비슷한 효과적인 수술로 생각된다.

영어초록

Purpose: To compare the intraoperative and short term postoperative outcomes of cataract surgery performed with custom pulse mode of OZil® and hyperpulse mode of conventional phacoemulsification
Methods: The patients underwent cataract surgery using the OZil® 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 μm in group 1, and 568.00±31.22 μm 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® custom pulse mode phacoemulsification is an effective procedure in cataract surgery as much as the conventional hyperpulse mode phacoemulsification.
