초록

목적: 특정 범위의 근시도 및 난시도에서 근시도 변화에 따른 고위수차의 증감 분석을 통해 근시도와 고위수차의 상관관계 알아보고자 하였다. 방법: Hartmann-Shack방식의 LADARWave 장비를 이용하여 총 992 안의 고위수차를 분석하였고, 현성굴절검사로 측정된 근시도값의 증가와 고위수차의 상관관계를 알아보았다. 결과: 전체 실험대상안에서 근시도가 증가함에 따라 총코마수차와 구면수차가 통계적으로 유의하게 증가하였으며, 트레포일 수차, 난시수차, 테트라포일 수차는 감소하였다. 근시도가 작은 군일수록 근시도에 따른 총코마수차의 변화가 더 급격하였으며 근시도가 작은 군에서는 통계적으로도 유의한 변화가 나타났다. 근시도가 -3.00 D 미만인 군은 근시도에 따른 구면수차값의 변화가 크지 않은 반면에 -3.00 D 이상인 군과 -6.00 D 이상인 군에서는 근시도에 따른 변화의 폭이 컸다. 특정 난시도 범위에서 근시도와 고위수차의 상관관계를 알아보았을 때 총코마수차는 난시도가 -1.00 D 이하인 군에서만 통계적으로 유의한 감소가 나타났다. 구면수차의 경우는 난시도가 작은 군일수록 근시도 증가에 따른 구면수차의 증가 폭이 더 커졌으며 모든 난시군에서 통계적으로 유의한 변화가 나타났다. 수평 및 수직코마수차는 특정 근시도 및 특정 난시도군별 일관성있는 증감관계가 성립하지 않았으며 통계적으로도 유의하지 않았다. 결론: 본 논문에서 밝힌 저위수차와 고위수차와의 상관관계를 통하여 시력의 질과 관련된 이해와 시력의 질 향상에 도움을 줄 수 있을 것으로 보여진다.

Purpose: The present study was aimed to investigate the correlation between higher-order aberration and myopic degree by the analysis of fluctuation of high-order aberration according to the change of myopic degree in certain ranges of myopia and astigmatism. Methods: The high-order aberration in a total of 992 eyes was analyzed by using a LADARWave device employing Hartmann-Shack system, and the relation between high-order aberration and myopia by the change of myopic degree through manifest refraction test. Results: In all subjects, spherical aberration 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 lower myopic degree, the change of coma aberration was greater by myopic degree and its change was significantly different. The change of spherical aberration by myopic degree was greatly large in the a group of -3.00 D or more 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 or less when analyzing the correlation between the higher-order aberrations and myopia in the certain groups of astigmatic 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. The consistent relationship in variations of horizontal and vertical coma aberration in certain myopic and astigmatic groups was neither established nor statistically significant. Conclusions: It is concluded that the correlation between the higher-order aberration and low-order aberration obtained from the results of the present study can help the understanding related to vision quality and the improvement of vision quality.
