The results of photorefractive keratectomy with Mitomycin-C in myopia correction after five years

Objective: to evaluate the results of photorefractive keratectomy (prk) with mitomycin c in myopia correction after five years. methods: this is a cross sectional study which included 145 eyes of 74 patients in 18 to 51 years age group that were undergoing photorefractive keratectomy with mitomycin c using allegretto wave eye-q 400-hz excimer laser platform in markazi eye center,tehran,iran. all the surgical procedures were performed by the same surgeon. after five years follow-up evaluation including bcva,ucva,refractive error measurement and external eye examination was performed. results: the mean diopter of spherical equivalent before surgery was -3.40±1.73. the following findings were obtained after 5 years follow up visit: the mean spherical equivalent value: -0.08±0.40,the mean log marucva: 0.02±0.07,the mean log mar bcva: 0.00±0.04. conclusion: prk is an effective,safe and predictable method used to correct myopia. the wave frontoptimized algorithm of the allegretto wave eye-q 400-hz excimer laser platform demonstrated good refractive and visual results. presence of variables such as gender,age and astigmatism before operation have no significant impact on the result of this operation. © 2016,professional medical publications. all rights reserved.
