Traumatic flap displacement and epithelial ingrowth after microkeratome-assisted laser in situ keratomileusis (LASIK) is a widely described potentially sight-threatening complication. However, this complication is rare when a femtosecond laser is used to create the LASIK flap. We present a case of epithelial ingrowth after late traumatic femtosecond-assisted LASIK flap dislocation. A 25-year-old woman presented to our emergency department after being scratched in the right eye by her cat. The patient had bilateral myopic femtosecond-assisted LASIK surgery 5 years previously with good postoperative visual acuity. Ocular examination showed nasal dislocation of the flap. Follow-up examinations showed epithelial ingrowth. She was referred for reconstructive surgery in which the epithelial ingrowth was removed and the flap repositioned. Follow-up examinations showed an excellent result.

微型角膜刀辅助激光原位角膜磨镶术（LASIK）后的创伤性皮瓣移位和上皮向内生长是一种广泛描述的潜在威胁视力的并发症。但是，当使用飞秒激光创建LASIK皮瓣时，这种并发症很少见。我们介绍了外伤性飞秒辅助LASIK皮瓣脱位后上皮向内生长的情况。一名25岁的女人被猫右眼抓伤后出现在我们的急诊室。该患者在5年前接受了双侧近视飞秒辅助LASIK手术，术后视力良好。眼部检查显示皮瓣鼻脱位。随访检查显示上皮向内生长。她被转介到重建手术中，其中去除了上皮向内生长并重新放置了皮瓣。
