Abstract
The classifying distribution by the Spherical lens and Aspherical lens was middle myopic, middle myopic astigmatism middle mixed astigmatism compared. The refractive erroeye spherical lens were S-3.00 ~ S-6.00Dptr for the middle myopic 16%, S-6.00Dptr 19%, S-3.00C-0.50(90.180) ~ S-6.00C-2.00Asix(90.180)57%, S-3.00C+0.50(90.180) ~ S-6.00C+2.00Axis(90.180) 8% for the compound myopic astigmatism. Aspherical lens were S-3.00 ~ S-6.00Dptr for the middle myopic 31%, S-6.00Dptr 36%, S-3.00C-0.50(90.180) ~ S-300C-2.00Axis(90.180) 21%, S-3.00C+0.50(90.180) ~ S-3.00C+2.00Axis(90.180)12%, for the compound hyperopic astigmatism.
구면렌즈와 비구면렌즈를 착용한 피검자의 굴절이상을 중등도근시, 중등도 근시성 복난시, 중등도 혼합난시이상의 착용자를 대상으로 비교하였다. 양안 굴절이상의 구면렌즈 착용자는 S-3.00 ~ S-6.00Dptr 가 16%, S-6.00D Dptr 이상이 19%, S-3.00C-0.50(90.180) ~ S-6.00C-2.00DptrAxis(90.180) 이 57%, S-3.00C+0.50 ~ S-6.00C+2.00DptrAxis(90.180)이 8%로 분포되어 나타났으며, 비구면렌즈 착용자는 S-3.00 S-6.00Dptr이 31%,S-6.00Dptr 이상이 36%, S-3.00C-0.50(90.180) ~ S-6.00C-2.00DptrAxis(90.180)이 21%, S-3.00C+0.50(90.180) ~ S-6.00C+2.00DptrAxis(90.180)이 12%로 분포되었다.
