Supplementary Material for: Femtosecond Laser-Assisted Anterior Lamellar Keratoplasty as a Treatment Modality for Recalcitrant Post-Laser in situ Keratomileusis Epithelial Ingrowth

The purpose is to present the outcomes of anterior lamellar keratoplasty for a case of post-laser in situ keratomileusis (LASIK) epithelial ingrowth. A 40-year-old male patient presented with epithelial ingrowth 14 years after primary LASIK with a microkeratome blade in the right eye following trauma. Multiple stromal bed washing was done over a period of 3 years, but recurrence of epithelial ingrowth was seen every time. Femtosecond laser-assisted anterior lamellar keratoplasty was performed in the right eye. Twelve months after the procedure, the patient’s corrected distance visual acuity improved to 6/9, and no recurrence was noted. Femtosecond laser-assisted anterior lamellar keratoplasty is an effective treatment modality in cases of recurrent recalcitrant epithelial ingrowth seen after LASIK.

本研究旨在报告1例准分子激光原位角膜磨镶术（LASIK）术后上皮内生患者接受前板层角膜移植术（anterior lamellar keratoplasty）的治疗结局。一名40岁男性患者，右眼在外伤后接受微型角膜刀辅助初次LASIK术后14年出现上皮内生。后续3年间，临床多次为其实施角膜基质床冲洗术，但每次术后均出现上皮内生复发。随后为该患者右眼行飞秒激光辅助前板层角膜移植术（femtosecond laser-assisted anterior lamellar keratoplasty）。术后12个月随访显示，患者的矫正远视力提升至6/9，未观察到上皮内生复发。综上，飞秒激光辅助前板层角膜移植术是治疗LASIK术后复发难治性上皮内生的有效治疗手段。
