強度屈折矯正におけるエキシマレーザー照射による家兎角膜屈折矯正手術効果について

Abstract

We studied the influence of excimer laser photorefractive keratectomy on high intended refractive corrections compared with moderate and low in 26 rabbits' eyes. Intended refractive corrections were-12 diopter (D), -6D, and -3D. The changes of haze, corneal depth, and corneal curvature were measured to 180 days. Haze disappeared in all rabbits by 180 days. The rates of post-operative corneal curvature compared with intended corneal curvature were not singnificant between 30 days and 90 days in all corrections. Ablation depths and corrections were reduced over -6D correction. We consider the incidence of low ablation depth and low correction.
