PURPOSE
To report severe scarring in a corneal graft after excimer laser photorefractive keratectomy.
METHODS
A 35-year-old man underwent photorefractive keratectomy twice for severe compound myopic astigmatism and anisometropia after penetrating keratoplasty.
RESULTS
Corneal opacity corresponded to areas of irregular epithelial thickness, focal absence of the basement membrane, loss of Bowman's layer, and stromal scarring in the ablation zone.
CONCLUSION
There may be an increased risk of severe corneal stromal scarring from photorefractive keratectomy in eyes that have had previous penetrating keratoplasty.
目的
报告准分子激光屈光性角膜切削术后角膜移植片中出现的严重瘢痕形成情况。
方法
一名35岁男性因穿透性角膜移植术后严重复合性近视散光和屈光参差接受了两次屈光性角膜切削术。
结果
角膜混浊对应于不规则上皮厚度区域、基底膜局灶性缺失、Bowman层缺失以及消融区内的基质瘢痕形成。
结论
既往有穿透性角膜移植术的眼睛进行屈光性角膜切削术时，发生严重角膜基质瘢痕形成的风险可能会增加。
