Unilateral corneal ectasia developed after small-incision lenticule extraction for mild myopia in a 43-year-old man with preoperative asymmetric astigmatism. The ectasia was diagnosed 4 years postoperatively. Preoperative data showed asymmetric astigmatism with no signs of forme fruste keratoconus. Inferior anterior curvature steepening exceeded 2.00 diopters without bulging of the posterior curvature, and pachymetric thickness exceeded 515 μm. Corneal ectasia can occur after small-incision lenticule extraction in patients older than 40 years with preoperative asymmetric astigmatism.
一名 43 岁男性因术前不对称性散光行微切口透镜切除术治疗轻度近视后，出现单侧角膜扩张。术后 4 年诊断为角膜扩张。术前数据显示不对称性散光，无早期圆锥角膜迹象。前下方曲率陡变超过 2.00 屈光度，后曲率无膨隆，角膜厚度超过 515μm。术前存在不对称性散光的 40 岁以上患者行微切口透镜切除术，可能会发生角膜扩张。
