目的：提醒眼科医生注意准分子激光屈光性角膜切削术(PRK)后圆锥形角膜可能加重。设计：临床病例报告。干预：低度近视的标准双侧PRK。主要观察指标：角膜地形图、角膜厚度和视力。结果：PRK术后出现双侧角膜扩张症。术前影像分析显示，左眼存在圆锥形角膜。结论：本文为首例PRK术后发生双侧角膜扩张症的低度近视患者。即使没有直接证据表明PRK加重了圆锥角膜的演变，PRK手术治疗圆锥角膜的安全性也必须考虑。
Objective: To alert ophthalmologists of the possibility of an aggravation of forme fruste keratoconus after photorefractive keratectomy (PRK).Design: Clinical case report. Intervention: Standard bilateral PRK for low myopia.Main Outcome Measures: Corneal topography, corneal thickness, and visual acuity.Results: Corneal ectasia occurred bilaterally after PRK. Retrospective analysis of preoperative videoker-atography indicated the existence of forme fruste keratoconus on the left eye.Conclusions: This article is the first case report of a bilateral corneal ectasia after PRK for low myopia. Even if there is no direct proof to demonstrate that PRK has worsened the evolution of keratoconus, the safety of the PRK procedure in forme fruste keratoconus must be considered.
