COMPARATIVE STUDY
ENGLISH ABSTRACT
JOURNAL ARTICLE
[A prospective intraindividual comparison between laser in situ keratomileusis and laser subepithelial keratectomy for myopia. 1-year follow-up results].
BACKGROUND: The aim of this study was to intraindividually compare the outcome of laser in situ keratomileusis (LASIK) and laser subepithelial keratectomy (LASEK) in patients with similar refraction in both eyes when treated with two different procedures.
PATIENTS AND METHODS: In this prospective nonrandomized study, 30 myopic patients with and without astigmatism were treated by Lasik in one eye and LasEk in the fellow eye. All eyes were treated using the MEL 70-G Excimer laser (Carl Zeiss Meditec, Germany). Uncorrected visual acuity (UCVA) and best spectacle-corrected visual acuity (BSCVA) as well as photopic contrast sensitivity (Pelli-Robson charts) and scotopic contrast sensitivity (Nyktometer, Rodenstock, Germany) were evaluated. The patients were also asked about their preferences regarding the procedures.
RESULTS: The preoperative spherical equivalent (SE) was -4.54+/-1.64 D and the mean BSCVA was 0.94 in Lasik eyes. The SE was -3.9+/-1.57 D and the BSCVA was 0.89 in LASEK eyes. The mean 1-year post-operative SE was -0.33+/-0.48 D in the Lasik eyes and -0.19+/-0.26 D in the LASEK eyes. Efficacy and safety were similar in the two groups, but Lasik eyes had a greater standard deviation at 1 year. Pelli-Robson contrast sensitivity was 10.75+/-3.05 in the Lasik eyes compared with 11.4+/-3.21 in the fellow LASEK eyes. Seventeen patients named Lasik and 12 patients named LASEK as their procedure of choice.
CONCLUSION: Both procedures enable similarly good results. LASEK showed a tendency to a smaller standard deviation in final refraction and better contrast sensitivity.
