초록

양안 굴절이상 차이에 의한 안광학상수 변화도 분석을 통한 양안 굴절이상 차이의 특성을 이해 할 수 있는 기초자료를 제공하고자 하였다. 20-59세의 건강한 성인 100명을 대상으로 KR-8800을 이용하여 등가구면 굴절력과 각막곡률 반경을, IOL Master를 사용하여 안축장길이와 전방깊이를 측정하였으며, 측정값의 차이는 우안 측정값-좌안 측정값의 차이값에 절대 값을 구하여 사용하였다. 전체 대상자의 등가구면 굴절력은 $-1.83{\pm}2.17D$이고, 안축장길이는 23.00~24.99mm, 각막곡률반경은 7.50~7.89mm, 전방깊이는 3.60~4.09mm의 범위에서 가장 많았다. 양안 등가구면 굴절력 차이에 따른 양안 안축장길이 차이와 양안 전방깊이의 차이가 유의한 상관관계가 있었다. 또한, 양안 굴절력 차이에 의한 양안 안축장 길이 차이가 가장 크고, 가장 높은 상관성이 있었다. 양안 굴절력 차이는 안광학 상수와 밀접한 관계가 있고, 양안 굴절력 차이에 의하여 여러 가지 시기능 문제가 발생 할 수 있으므로, 양안 굴절이상 차이에 따른 요인별 분류를 통한 융복합 연구가 필요하다.

The aim of study was to provide the preliminary data to find out characteristics of the difference between both refractive errors through analysis of ocular components variation. We measured spherical equivalent power and corneal radius with KR-8800, and axial length and anterior chamber depth with IOL Master, and the difference of measuring values between the right eye and left eye was applied as the absolute values in 100 adults aged 20~59 years. In all participants, the most common results showed that spherical equivalent power was $-1.83{\pm}2.17D$, axial length was 23.00~24.99mm, corneal radius was 7.50~7.89mm, and anterior chamber depth was 3.60~4.09mm. There are significant correlations between both eyes in axial length and anterior chamber depth with the difference of both spherical equivalent power. The difference of both axial lengths was the biggest with the difference of both refractive errors, and shown the highest correlation. The convergence complex study through classification by aspects is needed since the difference of both refractive errors is closely related with ocular components variation, and poor visual function would be caused by the difference of both refractive errors.
