Abstract

The aim of this report is to present the effects of spherical photorefractive keratectomy (PRK) by excimer laser on myopic astigmatism. Spherical PRK was performed in 96 eyes with myopia associated with astigmatism of between 0.75 and 2.00 diopters (D) using the Summit excimer laser. The reduction both in sphere and in cylinder was found to be highly statistically significant (P < 0.0001 for both). The mean reduction of cylinder was 46%. Astigmatic error of less than 2.00 D can be corrected significantly by spherical PRK.

摘要

本报告旨在呈现准分子激光球面屈光性角膜切削术（PRK）对近视散光的影响。使用Summit准分子激光对96只伴有0.75至2.00屈光度（D）散光的近视眼睛进行了球面PRK手术。结果发现，球镜和柱镜的降低在统计学上均具有高度显著性（两者P均<0.0001）。柱镜的平均降低率为46%。球面PRK可显著矫正低于2.00 D的散光误差。
