We report an iatrogenic corneal ectasia that developed after laser in situ keratomileusis (LASIK) in a case of forme fruste keratoconus. One month postoperatively, corneal topography revealed a central steep area that showed rapid progression. Visual acuity in the eye decreased from 20/20 to 20/80. Corneas with forme fruste keratoconus may have altered biomechanical properties compared with normal corneas. Forme fruste keratoconus may be a contraindication for LASIK.
我们报告了1例在圆锥角膜顿挫型患者接受准分子原位角膜磨镶术（LASIK）后发生的医源性角膜扩张。术后1个月，角膜地形图显示中央陡峭区并呈现快速进展。患眼视力从20/20降至20/80。与正常角膜相比，圆锥角膜顿挫型的角膜生物力学特性可能已发生改变。圆锥角膜顿挫型可能是LASIK手术的禁忌证。
