근시도가 나이에 따라 유발되는 고위수차의 변화에 미치는 영향

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