Nineteen eyes underwent photorefractive keratectomy to correct myopia. Using the specular microscope, we observed the central corneal epithelium of each eye preoperatively and at one, three, and six months after surgery. A normal epithelial pattern was observed in 18 eyes (94.7%) at one and three months and in 19 eyes (100%) at six months after surgery. There was no statistically significant difference in the pre- and postoperative mean cell area and corresponding coefficient of variation. These results suggest that the destruction of Bowman's layer produced by photorefractive keratectomy does not affect the morphologic characteristics of the most superficial layer of the corneal epithelium.
19只眼睛接受了准分子激光原位角膜磨镶术来矫正近视。我们使用角膜内皮显微镜，在术前以及术后1个月、3个月和6个月观察了每只眼睛的中央角膜上皮。术后1个月和3个月时，18只眼睛（94.7%）观察到正常的上皮形态，术后6个月时，19只眼睛（100%）观察到正常的上皮形态。术前和术后的平均细胞面积及相应的变异系数没有统计学上的显著差异。这些结果表明，准分子激光原位角膜磨镶术所造成的前弹力层破坏并不影响角膜上皮最表层的形态学特征。
