The present study was aimed to investigate the correlation between higher-order aberration and myopicdegree by the analysis of fluctuation of high-order aberration according to the change of myopic degree in certainranges of myopia and astigmatism. Methods: The high-order aberration in a total of 992 eyes was analyzed byusing a LADARWave device employing Hartmann-Shack system, and the relation between high-order aberrationand myopia by the change of myopic degree through manifest refraction test. Results: In all subjects, sphericalaberration and total coma aberration were significantly increased by the increase of myopic degree, however,trefoil aberration and astigmatic aberration and tetrafoil aberration were decreased. With the group of lowermyopic degree, the change of coma aberration was greater by myopic degree and its change was significantlydifferent. The change of spherical aberration by myopic degree was greatly large in the a group of −3.00 D ormore and the group of −6.00 D or more where as its change was not large in the group of lower than −3.00 D.
The significant decrease of coma aberration was observed only in the group of astigmatic degree of −1.00 D orless when analyzing the correlation between the higher-order aberrations and myopia in the certain groups ofastigmatic degree. In the case of spherical aberration, the significant change was shown in all astigmatic groups,however, its increase was larger with the increase of myopic degree in lower degree of astigmatism. Theconsistent relationship in variations of horizontal and vertical coma aberration in certain myopic and astigmaticgroups was neither established nor statistically significant. Conclusions: It is concluded that the correlationbetween the higher-order aberration and low-order aberration obtained from the results of the present study canhelp the understanding related to vision quality and the improvement of vision quality.
