We report a case of transient corneal ectasia developed after phacoemulsification in an eye previously treated with INTRACOR. There was a myopic refractive surprise after cataract surgery. Corneal tomography showed an increase in keratometry and elevation profile compared with preoperative examination. Soft contact lenses and intraocular pressure-lowering medications were prescribed as interim treatment. Clinical improvement was seen gradually, and the resolution of myopia and ectasia was achieved at 3 months. We believe that high intraocular pressure during phacoemulsification and the weakening effect of femtosecond intrastromal presbyopic treatment can be the culprits.
我们报告了一例在先前接受 INTRACOR 治疗的眼睛进行超声乳化术后出现的短暂性角膜扩张病例。白内障手术后出现近视屈光意外。角膜断层扫描显示与术前检查相比，角膜曲率计读数增加和隆起度增加。软性隐形眼镜和降眼压药物被开处作为临时治疗。临床改善逐渐出现，3 个月时近视和扩张得到解决。我们认为，超声乳化过程中的高眼压和飞秒间质老视治疗的削弱作用可能是罪魁祸首。
