Abstract

To specify the standard of LASEK surgery, this study examined the determination factors affecting the high order aberrations (HOAs) in preoperative and postoperative LASEK. 51 adult patients (102 eyes) were evaluated at the baseline and 2 months after LASEK surgery from Nov 2011 to Jul 2012. The postoperative HOAs ($0.538{\mu}m$) were higher than the preoperative ($0.341{\mu}m$). In linear regression analysis, the refractive components that affected the postoperative HOAs were $J_0$ of corneal astigmatism (CA, 0.400), $J_0$ of refractive astigmatism (RA, 0.389), corneal astigmatism (CA, 0.282), spherical equivalent (SE, 0.239), refractive astigmatism (RA, 0.213), and pupil size (PS, 0.194) with a high R. In multiple regression, $J_0$ of CA, PS and SE were significant factors with the postoperative HOAs. In conclusion, both HOAs and $J_0$ of CA should be considered when determining the suitable factors for LASEK surgery.

라섹 수술 방법을 결정하기 위한 기준을 상세화하고자 고식적인 라섹 수술 전과 후의 고위수차에 영향을 미치는 결정변수들을 분석하였다. 2011년 11월부터 2012년 7월까지 고식적 라섹 수술을 한 대상자 중 수술한지 2개월 후 고위수차검사가 가능한 51명(102안)을 대상으로 하였다. 고위수차는 수술 전 $0.341{\mu}m$에서 수술 후 $0.538{\mu}m$로 증가하였다. 선형회귀분석에서 수술 후의 고위수차 변동에 영향을 미치는 수술 전의 굴절성분은 설명력 크기순으로 각막난시 $J_0$ 성분이 0.400, 굴절성난시 $J_0$ 성분이 0.389, 각막난시량이 0.282, 구면렌즈대응치가 0.239, 굴절성난시량이 0.213, 동공크기가 0.194였다. 다중회귀분석에서 수술 후의 고위수차와 통계적으로 의미가 있는 변수는 각막난시 $J_0$ 성분, 동공크기, 구면렌즈대응치였다. 따라서 개인에게 적합한 수술 방법 결정을 위해서는 고위수차와 더불어 파워벡터분석에 의한 각막난시도 함께 고려하는 것이 필요하다.
