Excimer laser photorefractive keratectomy in low and medium myopia

ABSTRACT

In this study, we analysed the refractive results and complications obtained in 430 myopic eyes having myopia less than -9.00 diopters and treated with excimer photorefractive keratectomy. All eyes were treated with excimer laser Aesculap-Meditec MEL - 60 utilizing the program of tapered transitional zone [TTZ]. Patients were followed up for 2 years after the surgery. In the group of low myopia [less than-6.00 diopters]; a refractive result between 0 and-1.00 diopters was adchieved in 81.91% of treated eyes, while in the group of medium myopia [-6.00 to -9.00 diopters] this result was obtained in 77.68%. The predictability of the technique in the correction of myopia lies between 84.04% in low myopia and 78.51% in medium myopia. The obtained results along with their stability with time and low incidence of complications make excimer laser PRK the technique of choice for surgical correction of myopia till -9.00 diopters
