title: Comparison of photorefractive keratectomy on one eye and laser in situ keratomileusis on the other eye of the same patient.
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).
  
  
  CONCLUSIONS
  In our study, eyes treated with LASIK had better results than eyes treated with PRK.
