PURPOSE: To report the technique and small case series results of femtosecond laser-assisted sutureless anterior lamellar keratoplasty (FALK) for anterior corneal pathology. DESIGN: Retrospective, noncomparative, interventional case series. PARTICIPANTS: Twelve consecutive eyes from 12 patients with anterior corneal scarring. INTERVENTION: Femtosecond laser-assisted sutureless anterior lamellar keratoplasty. MAIN OUTCOME MEASURES: Measured parameters included femtosecond laser settings, technique, uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), and complications. RESULTS: Mean follow-up was 12.7 months (range, 6-24). No intraoperative complications were found. Uncorrected visual acuity (VA) improved in 7 eyes (58.3%) compared with preoperative VA. The mean difference between preoperative and postoperative UCVAs was a gain of 2.5 lines (range, unchanged-7 lines). Best-corrected VA was unchanged or improved in all eyes compared with preoperative levels. The mean difference between preoperative and postoperative BCVAs was a gain of 3.8 lines (range, unchanged-8 lines). In 2 eyes, adjuvant surgical procedures were performed (one treated with phototherapeutic keratectomy and the other with photorefractive keratectomy). Six patients (50%) developed dry eye after FALK, which improved during the follow-up period. No graft rejection, infection, or epithelial ingrowth was found in this series of patients. CONCLUSIONS: Femtosecond laser-assisted sutureless anterior lamellar keratoplasty could improve UCVA and BCVA in patients with anterior corneal pathology.
