Abstract:
Purpose: To evaluate the results of photorefractive keratectomy (PRK) with mitomycin C in myopia correction after eight years. Methods: The present cross-sectional study was carried out on 62 patients,19 to 59 years old, who were undergoing Photorefractive keratectomy using Wave front-optimized surgery plan via Allegreto Wave Eye-Q. All of the surgical procedures were performed by one surgeon. After 8 years, follow-up visits were paid performing eye examination including BCVA, UCVA, Refractive error measurement, Orbscan2 and external eye examination. Results: The mean diopter of spherical equivalent before surgery was -3.65±1.53. The following findings were obtained after 5 years follow up visit: The mean spherical equivalent value: -0.12±0.38, the mean Log MARUCVA: 0.06±0.08, the mean Log MAR BCVA: 0.00±0.06. The mean change of flat K and steep K were -2.87±1.57 and - 2.98±1.77, respectively. Conclusion: After eight years PRK is an effective, safe and predictable method used to correct myopia. The wavefront optimized algorithm of the Allegretto Wave Eye-Q 400-Hz excimer laser platform demonstrated good refractive and visual results.
