목적: 여러 가지 기기들을 이용하여 안축장, 각막곡률치, 그리고 각막윤부직경을 측정하여 비교하고, 일치도를 분석하고자 한다. 대상과 방법: 백내장수술 전 환자 56명 64안을 대상으로 Galilei™, Lenstar®, A-scan을 이용해 안축장을 측정, Galilei™, Lenstar®, ARK를 이용해 각막곡률치를 측정, 74명 86안을 대상으로 Galilei™, Lenstar®를 이용하여 각막윤부직경을 측정하고 분석했다. 결과: Galilei™, Lenstar®, A-scan을 이용해 측정한 안축장은 측정치 간에 높은 양의 상관관계를 보였으며(p＜0.001), 통계적으로 유의한 차이가 없었다(p=0.611). 95% 일치도 범위는 Lenstar®와 A-scan이 0.22 mm로 가장 작았다. Galilei™, Lenstar®, ARK를 이용하여 측정한 각막곡률치는 측정치 간에 높은 양의 상관관계를 보였으며(p＜0.001), 통계적으로 유의한 차이가 없었다(p=0.657). 95% 일치도 범위는 Lenstar®와 ARK에서 1.83D로 상대적으로 작았다. Galilei™, Lenstar®를 이용하여 측정한 각막윤부직경 역시 측정치 간에 높은 양의 상관관계를 보였으며(p＜0.001), 통계적으로 유의한 차이가 있었다(p=0.011). 95% 일치도 범위는 2.20 mm였다. 결론: 여러 가지 기기들을 이용하여 측정한 안축장, 각막곡률치, 각막윤부직경은 상관성이 높고 유의한 차이를 보이지 않으나 일치도는 모두 높지 않아 기기들 간에 상호동등하게 호환해서 사용하는 것은 주의를 기해야 하며, 신중한 해석을 거쳐 사용하여야 할 것이다.
Abstract
Purpose: To compare the accuracy and clinical usefulness of various devices by measuring axial length, keratometry, and white-to-white. Methods: In 64 eyes of 56 cataract patients, axial length was measured using Galilei™, Lenstar®, and A-scans, and keratometry was measured using Galilei™, Lenstar®, and ARK. In 86 eyes of 74 cataract patients, white-to-white was measured using Galilei™ and Lenstar®. Results: The average axial length measurements using Galilei™, Lenstar®, and A-scans were significantly correlated (p ＜ 0.001), but without a statistically significant difference (p = 0.611). The 95% agreement range was the smallest at 0.22 mm for the Lenstar® and A-scans. The average mean K using Galilei™, Lenstar®, and ARK were significantly correlated (p ＜ 0.001), but without a statistically significant difference (p = 0.657). The 95% agreement range was relatively small at 1.83 D for Lenstar® and ARK. The average white-to-white using Galilei™ and Lenstar® were significantly correlated (p ＜ 0.001), with a statistically significant difference (p = 0.011). The 95% agreement range was 2.20 mm. Conclusions: Axial length, keratometry, and white-to-white measured by different devices were highly correlated and were not statistically different; however, agreement was low between measurements. It is therefore important to consider these findings when using them equally.
