Photorefractive keratectomy results in myopic patients with thin cornea eyes Hassan Hashemi, Mohammad Miraftab, Soheila Asgari1 Noor Ophthalmology Research Center, Noor Eye Hospital, 1Department of Epidemiology and Biostatistics, School of Public Health, Tehran University of Medical Sciences, International Campus, Tehran, Iran
Background: To evaluate the results of visual acuity and quality, and corneal integrity in myopic patients with a thin cornea who received photorefractive keratectomy (PRK). Materials and Methods: In this before-after interventional study, 30 myopic eyes with a myopia −3.76 ± 1.72 (−6.50 to −1.25) D and a corneal thickness of 486.03 ± 11.93 (452-499) μm at the thinnest point received PRK. In myopia was more than 4D, mitomycin C was used with PRK. The surgery was performed with an excimer laser (VISX STAR, Abbott Medical Optics, Abbott Park, US). Results: The safety and the efficacy index of the surgery was 1.01 ± 0.05 and 1.00 ± 0.05 in these patients, respectively. All the patients were within ±0.5D of emmetropia 1
Introduction Treatment of low to moderate myopia with excimer laser refractive procedures like laser-assisted in situ keratomileusis (LASIK),[1] laser epithelial keratomileusis (LASEK),[2] and photorefractive keratectomy (PRK)[3] has desirable safety and efficacy. Studies have shown that LASIK in patients with corneal thickness
