Objective Decentered flaps are rarely reported after femtosecond laser-assisted in situ keratomileusis flap procedures. We present a patient with a decentered flap after preparation of a corneal flap using the Femto LDV technique. Methods The 22-year-old man required a redo operation because of a decentered corneal flap. It was performed the same day at the patient's insistence and with his consent. The new corneal flap for the redo surgery was prepared using the femtosecond laser technique and IntraLase. Results Uncorrected visual acuity for each eye was 1.2 during the 12-month follow-up. The results of the Femtosecond laser technique showed good predictability and repeatability regarding the preparation of corneal flaps, but it still may cause some intraoperative complications. Conclusion Once redo surgery is needed, the size and depth of the initially prepared flap should be determined using anterior segment optical coherence tomography to pre-set the parameters for preparation of the redo flap.
目的 飞秒激光制瓣准分子原位角膜磨镶术（LASIK）后偏心瓣的报道很少。我们报告1例使用飞秒激光制瓣仪（Femto LDV）技术制作角膜瓣后出现偏心瓣的患者。方法 该22岁男性因角膜瓣偏心需要再次手术。在患者的坚持和同意下，于同日进行了再次手术。再次手术的新角膜瓣使用飞秒激光技术和IntraLase制作。结果 在12个月的随访期间，每只眼的裸眼视力均为1.2。飞秒激光技术在角膜瓣制作方面显示出良好的可预测性和可重复性，但仍可能引起一些术中并发症。结论 一旦需要再次手术，应使用眼前节光学相干断层扫描确定最初制作瓣的大小和深度，以便预设再次制作瓣的参数。
