To evaluate the efficacy of photorefractive keratectomy (PRK) in progressive central epithelial ingrowth after buttonholes after laser in situ keratomileusis (LASIK).
Two eyes of two patients with progressive central epithelial ingrowth and fibrosis in flap buttonholes after LASIK underwent PRK 6 months following primary surgery.
Epithelial ingrowth was treated successfully in both eyes. The uncorrected visual acuities were 20/20, and there was no evidence of recurrent epithelial ingrowth after 6 months.
Photorefractive keratectomy is a useful modality in the treatment of central epithelial ingrowth in buttonholes following LASIK. As a single-step surgery, it offers both therapeutic and optical advantages by simultaneously clearing the corneal opacity and correcting the refractive error in selected cases.
评估准分子激光角膜切削术（PRK）治疗准分子原位角膜磨镶术（LASIK）后瓣切口处中央上皮内生进展的疗效。
2例LASIK术后瓣切口处发生中央上皮内生并纤维化的患者的2只眼，在初次手术后6个月接受了PRK治疗。
两只眼的上皮内生均得到成功治疗。裸眼视力均为20/20，6个月后无上皮内生复发迹象。
准分子激光角膜切削术是治疗LASIK后瓣切口处中央上皮内生的一种有效方法。作为一种单步手术，在某些病例中，它通过同时清除角膜混浊和矫正屈光不正，兼具治疗和光学优势。
