We describe a case of bilateral keratectasia after laser in situ keratomileusis (LASIK) in a patient with previous radial keratotomy and astigmatic keratotomy. The best spectacle-corrected visual acuity (BSCVA) was 20/25 in both eyes. After uneventful LASIK was performed in both eyes for low myopic astigmatism, the patient presented with progressive myopia and astigmatism and a BSCVA of 20/50 in both eyes. Videokeratography showed progressive deformation of the cornea, increasing K-values over 50.0 diopters, and irregular astigmatism. The best corrected visual acuity in both eyes improved to 20/25 with rigid poly(methyl methacrylate) contact lenses.
我们描述了一例曾接受放射状角膜切开术和散光性角膜切开术的患者在准分子原位角膜磨镶术(LASIK)后发生双侧角膜扩张的病例。双眼最佳矫正视力(BSCVA)均为20/25。双眼因低度近视散光行LASIK手术过程顺利,但术后患者出现渐进性近视和散光,双眼BSCVA降至20/50。角膜地形图显示角膜逐渐变形,角膜曲率值(K值)增加超过50.0屈光度,且存在不规则散光。佩戴硬性聚甲基丙烯酸甲酯隐形眼镜后,双眼最佳矫正视力提高至20/25。
