[Keratoconus after transepithelial photorefractive keratectomy: a case report].

A 24-year-old male was treated with transepithelial photorefractive keratectomy for myopia in both eyes 5 years ago. He had allergic conjunctivitis for 3 years. The night vision of both eyes was decreased for 2 years. The clinical diagnosis was keratoconus binoculus. Therefore, corneal collagen cross-linking was performed in both eyes, and the follow-up was 6 months. Confocal microscopy showed that the cross-linking of riboflavin and fiber amino was successful, and the keratoconus did not progress during the follow-up. Although there have been few case reports of keratoconus after transepithelial photorefractive keratectomy at home and abroad, great importance should be attached to the early and comprehensive screening of keratoconus in the candidates of refractive surgery in order to improve the long-term safety.1例24岁双眼夜间视力下降2年男性患者，5年前行经上皮准分子激光角膜切削术（TransPRK）治疗双眼近视眼，过敏性结膜炎病史3年，临床经检查诊断为双眼圆锥角膜。行双眼经上皮角膜胶原交联术，术后随访6个月，活体共聚焦显微镜检查显示核黄素与纤维氨基交联成功，圆锥角膜无进展。针对角膜屈光手术候选患者群体，临床应高度重视圆锥角膜的早期全面筛查，以提高角膜屈光手术的长期安全性。.
