Abstract

OBJECTIVE: The aim of this study was to compare the results of excimer laser photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) in the same patient. METHODS: All consecutive patients who underwent PRK in one eye and LASIK in the second eye using the same excimer laser (Nidek EC-5000) and had at least 12 months of follow-up were included in this retrospective study (N=23). Uncorrected and spectacle-corrected visual acuity, final spherical equivalent refraction, and degree of haze were compared. RESULTS: Mean postoperative spherical equivalent refraction in the group of eyes that underwent PRK was +0.73 D (range, -5.50 to +3.50 D). Mean postoperative spherical equivalent refraction in the group of eyes that underwent LASIK was +0.07 D (range, -1.25 to +3.50 D)(P=.046). CONCLUSION: In our study, eyes treated with LASIK had better results than eyes treated with PRK.
