One-Year Outcomes of Femtosecond Laser-Assisted LASIK Following Previous Radial Keratotomy

Abstract

To report the 1-year outcomes of LASIK in patients with previous radial keratotomy using a novel femtosecond laser platform. The charts of 27 eyes of 18 patients who underwent femtosecond laser-assisted LASIK with the WaveLight FS200 laser (Alcon Laboratories, Inc., Fort Worth, TX) for consecutive hyperopia following previous radial keratotomy were retrospectively reviewed at a single private practice location. The preoperative characteristics, intraoperative details, and postoperative results were evaluated. All 27 eyes had successful femtosecond laser flap creation without significant intraoperative or postoperative complications. Uncorrected visual acuity significantly improved postoperatively to 0.13 ± 0.13 logMAR at 12 months of follow-up (P < .0001). Postoperative spherical equivalent averaged 0.11 ± 0.53 diopters. None of the patients lost any lines of corrected distance visual acuity during the postoperative period. The femtosecond laser technique described by this study resulted in a safe and effective way to deliver LASIK following previous radial keratotomy. Future investigations are needed to further validate the outcomes of this study.
