초록

목적: 펨토초레이저 백내장 수술의 수정체낭원형절개(continuous curvilinear capsulorhexis, CCC)의 정확성에 대해 전안부 광간섭단층촬영기를 이용하여 고식적 백내장 수술과 비교하였다. 대상과 방법: 펨토초레이저 백내장 수술을 받은 30명 30안과 고식적 백내장 수술 환자 30명 30안을 대상으로 술 후 1개월에 전안부광간섭 단층촬영기를 이용하여 CCC의 직경, 원형정도, 동공 중심을 기준으로 CCC의 중심위치를 비교하였다. 결과: 펨토초군에서 가장 긴 CCC 직경의 평균은 4.96 ± 0.23 mm, 대조군은 4.70 ± 0.82 mm, 가장 짧은 CCC 직경의 평균은 펨토초군이 4.91 ± 0.23 mm, 대조군은 4.48 ± 0.64 mm로 가장 짧은 CCC 직경에서 두 군이 통계학적으로 유의한 차이를 보였다(p=0.000). 원형정도에서 펨토초군은 0.99 ± 0.01, 대조군은 0.91 ± 0.13으로 유의한 차이를 보였다(p=0.000). 동공중심으로부터CCC 중심까지의 거리가 펨토초군에서는 0.18 ± 0.09 mm, 대조군에서 0.26 ± 0.17 mm로, 펨토초군에서 대조군에 비해 CCC 중심이동공 중심에 유의하게 더 가까웠다(p=0.038). 결론: 펨토초레이저 백내장 수술에서 고식적 백내장 수술보다 술자가 원하는 정밀하고 재현성 높은 CCC가 가능하였다.

Abstract

Purpose: To compare parameters of femtosecond laser and manual continuous curvilinear capsulorhexis (CCC) using anteriorsegment optical coherence tomography (AS-OCT). Methods: Femtosecond laser cataract surgery was performed in 30 eyes of 30 patients, and conventional cataract surgery witha manual CCC in 30 eyes of 30 patients. One month after surgery, CCC diameters, circularity of capsulotomy, and distance betweenthe CCC and pupil center were analyzed using the AS-OCT. Results: Mean maximal CCC diameter was 4.96 ± 0.23 mm in the femtosecond laser group, and 4.70 ± 0.82 mm in the manualCCC group. Mean minimal CCC diameter was 4.91 ± 0.23 mm in the femtosecond group, and 4.48 ± 0.64 mm in the manualCCC group showing significant difference between the two groups (p = 0.000). Circularity of capsulotomy was 0.99 ± 0.01 in thefemtosecond group and 0.91 ± 0.13 in the manual CCC group and was statistically different between the 2 groups (p = 0.000). The distance from the CCC center to the pupil center was 0.18 ± 0.09 mm in the femtosecond group and 0.26 ± 0.17 mm in themanual CCC group. The CCC center was closer to the pupil center in the femtosecond than in the manual CCC group (p = 0.038). Conclusions: Properly sized and shaped capsulotomy can be expected in femtosecond laser CCC compared with manual CCC.
