Abstract

Purpose: The present study was aimed to investigate the change of higher-order aberrations induced by aging and the effect of myopic degree on the correlation between age and higher-order aberrations. Methods: The higher-order aberrations in 931 eyes aged from 20 to 60 were measured by using a LADARWave device employing Hartmann-Shack system to analyze the effect of myopic degree measured by manifest refraction test on higher-order aberrations. Results: Coma and vertical coma aberrations were significantly decreased by the increase of myopic degree while vertical astigmatic aberration was significantly increased. The correlations of age and coma, vertical coma, spherical, vertical trefoil, horizontal trefoil, vertical astigmatic, horizontal astigmatic and vertical tetrafoil aberrations depended on the myopic degree, except for horizontal coma and horizontal tetrafoil aberrations. Conclusions: It is suggested to consider the myopic degree for the refractive correction including the laser surgery based on the present result that higher-order aberrations are affected by the myopic degree.

목적: 나이의 증가에 따른 고위수차의 변화를 분석하고, 근시도가 나이와 고위수차 변화와의 상관관계에 미치는 영향을 알아보고자 하였다. 방법: Hartmann-Shack 방식의 LADARWave 장비를 이용하여 20세에서 60세 931안의 고위수차를 분석하였고, 현성굴절검사를 통해 측정된 근시도가 고위수차에 미치는 영향을 분석하였다. 결과: 코마수차, 수직코마수차는 나이가 증가함에 따라 통계적으로 유의하게 감소하였으며, 수직난시수차는 통계적으로 유의하게 증가하였다. 코마수차, 수직코마수차, 구면수차, 수직트레포일수차, 수평트레포일수차, 수직난시수차, 수평난시수차, 수직테트라포일수차와 나이와의 상관관계는 근시도에 의해 영향을 받았으며 수평코마수차와 수평테트라포일수차는 영향을 받지 않았다. 결론: 본 연구에서는 근시도수가 나이에 따라 유발되는 고위수차의 변화에 영향을 줄 수 있음을 밝혔으며 시력교정술이나 시력교정용구 사용 시 시력의 질을 위하여 이의 고려를 제안하고자 한다.
