초록
목적: 슬릿광주사 각막형태검사기(ORBscan IIzⓇ, Bausch & Lomb), 저간섭성 반사계(LenstarⓇ, Haag-Streit) 및 Castroviejo Caliper를 이용하여 측정한 수평각막직경을 비롯한 전안부 계측치를 서로 비교해 보고자 하였다. 대상과 방법: 굴절교정수술을 시행 받은 36명 72안을 대상으로 술전에 ORBscanⓇ, LenstarⓇ를 이용한 수평각막직경을 측정값과caliper를 이용한 수평각막직경 측정 결과와 비교하였다. 추가적으로 ORBscanⓇ, LenstarⓇ 장비를 이용하여 술전에 측정한 중심각막두께, 전방 깊이, 각막 곡률 및 동공 크기를 비교하였다. 결과: 수평각막직경은 ORBscanⓇ과 caliper를 이용하여 측정한 값 사이에는 유의한 차이가 없었으며, LenstarⓇ로 측정한 경우 앞의두 가지 방법에 비해 모두 유의하게 크게 측정되었다(모두 p＜0.001). 중심각막 두께는 ORBscanⓇ이 Lenstar LS900Ⓡ에 비해 두껍게측정되었으며(p＜0.001), 각막곡률도 ORBscanⓇ이 크게 측정되었다. 전방 깊이는 LenstarⓇ가 깊게 측정되었고(p＜0.001) 동공크기도LenstarⓇ의 경우 더 크게 측정되었다(p＜0.001). 결론: LenstarⓇ를 이용하여 측정한 수평각막직경과 전방 깊이는 ORBscanⓇ이나 caliper의 측정값에 비해 크게 측정되기 때문에 후방안내렌즈삽입술의 경우 실제보다 큰 사이즈의 렌즈를 선택하게 되어 high vaulting을 초래할 수 있으므로 검사장비에 따른 차이를고려해야 할 것으로 생각한다.
Abstract
Purpose: To compare the results of anterior segment biometry including white-to-white (WTW) between scanning-slit topography(ORBscan IIz®, Bausch & Lomb), optical low-coherence reflectometry (OLCR) biometry (Lenstar®, Haag-Streit), and Castroviejocalipers. Methods: Measurements on 72 eyes of 36 patients that underwent refractive surgery were measured using ORBscan®,Lenstar®, and calipers and compared. Ocular biometry parameters used in this study included the WTW, central corneal thickness,anterior chamber depth (ACD), keratometry, and pupil size. Results: The WTW measurements using ORBscan® and calipers (11.57 ± 0.35 mm and 11.58 ± 0.34 mm, respectively) were statisticallysimilar. However, the measurement using Lenstar® (12.05 ± 0.40 mm) was significantly greater than with the other methods(p < 0.001). Central corneal thickness and keratometry measurements using ORBscan® were greater than when using Lenstar® (p= 0.01 for both). ACD and pupil size measurement using Lenstar® were greater than when using ORBscan® (p < 0.001 for both). Conclusions: Because WTW and ACD measurements using Lenstar® were greater than when using ORBscan® and calipers,unexpected high-vaulting may be observed due to the selection of a larger-sized posterior chamber phakic intraocular lens. Therefore, the differences in measurements obtained when using these methods should be considered.
