The baseline characteristics, intraoperative findings and postoperative outcomes were analyzed.Results: All 17 eyes underwent femtosecond-assisted LASIK with de novo flap creation without significant intraoperative or postoperative complications. Uncorrected visual acuity improved postoperatively (p< 0.0001) and remained stable at 6 months follow-up. None of the subjects lost any lines of best spectacle corrected visual acuity or developed epithelial ingrowth during the postoperative period.Conclusion: The femtosecond laser technique described in this report can provide a safe and effective method to deliver LASIK following previous microkeratome LASIK. Future investigations are required to further validate the findings in this study.Keywords: LASIK, cornea, optical coherence tomography
