Abstract

Purpose: To present a case of asymmetric progressive corneal ectasia following femtosecond laser-assisted small-incision lenticule extraction.

Methods: After obtaining a patient's consent, preoperative and postoperative findings were represented in this case report.

Results: A 29-year-old woman presented with normal preoperative Placido disk-based corneal topography and tomographic findings. The corrected refractive error was -4.00 and -4.50 -1.00 × 177 in the right and left eye, respectively, with a maximal lenticule thickness of 87 and 115 μm OD/OS. Twenty months postoperatively, the patient presented with decreased vision in the left eye and mild ectatic changes in corneal shape in both eyes. The retrospective evaluation of the integrated rotating Scheimpflug tomography (Pentacam; Oculus, Wetzlar, Germany) and corneal biomechanical (Corvis ST) assessment revealed moderate susceptibility for corneal ectasia in the right eye and a significant corneal ectasia in the left eye.

Conclusion: This case corroborates the need for an enhanced multimodal approach to characterize the risk for postoperative corneal ectasia after laser vision correction.

激光辅助小切口扁桃体摘除术后的角膜异位：加强外伤风险评估的案例。

目的：介绍一例飞秒激光辅助小切口角膜透镜摘除术后的不对称渐进性角膜异位：方法：在征得患者同意后，在本病例报告中介绍术前和术后结果：一名 29 岁的女性患者术前的 Placido 盘式角膜地形图和断层扫描结果正常。右眼和左眼的矫正屈光度分别为-4.00 和 -4.50 -1.00 × 177，最大皮膜厚度分别为 87 和 115 μm OD/OS。术后 20 个月，患者左眼视力下降，双眼角膜形状出现轻度异位变化。综合旋转式 Scheimpflug 层析成像（Pentacam；Oculus，德国韦茨拉尔）和角膜生物力学（Corvis ST）评估的回顾性评估显示，右眼角膜异位的易感性为中度，左眼角膜异位明显：本病例证实，需要加强多模式方法，以确定激光视力矫正术后角膜异位的风险。
