Abstract

Background and Aim
The aim of this study was the evaluation of the results of photorefractive keratectomy in myopia
Correction.
Materials and Methods
 The present cross-sectional study was carried out on 74 patients,18 to 51 years old, who were undergoing Photorefractive keratectomy using Wave front-optimized surgery plan via Allegreto Wave Eye-Q in Markazi clinic. All of the surgical procedures were performed by one surgeon. After 5 years, follow-up visits were paid performing eye examination including BCVA, UCVA, Refractive error measurement, and external eye examination.
Result
The mean diopter of spherical equivalent before the surgery was -3.40±1.73.The following findings were obtained in follow-up visits after 5 years: The mean equivalent sphere value: -0.08±0/40, the mean logUCVA: 0.02±0.076, and the mean logBCVA: 0.00±0.044.
Conclusion
Photorefractive keratectomy by Mitomicyne C and Allegreto Wave Eye-Q is a safe procedure to correct myopia and other factors, including gender, age, and the presence of astigmatism before surgery, have little if any effect on the results.
