Patient going for PRK treatment for refractive error in Al-Jouf region, Saudi Arabia
Main Article Content
Abstract
Introduction: Photorefractive keratectomy (PRK) has been widely used as an efficient, secure, and cost-effective method for treating patients with low to moderate myopia. This study was aimed to evaluate the prevalence of accepted and rejected reasons candidates going for PRK treatment for refractive error in Aljouf region, Saudi Arabia.
Material and Methods: This retrospective study was conducted among 255 candidates going for PRK treatment for refractive in the department of ophthalmology at tertiary care hospital in Aljouf region, Saudi Arabia from August 2023 to October 2023.The following measurements of eye were noted for the enrolled patients in the study: visual acuity (VA) sine correction (SC) Visual acuity cum correction (CC), refractive error (RE) Central corneal thickness (CCT), Pentacam Astigmatism, keratometry (K1 and K2), spherical, cylindrical, and axis power in diopters, cycloplegic refraction, and pupillary diameter in normal daytime illumination in a room.
Results: Total 255 patients were included in this study among them 119 (46.67%) male and 136 (53.33%) female with average age of 26 in both male and female. Total 160 were fit and 95 were not fit. Visual acuity cum correction (CC) ocular dexter (OD) and Visual acuity cum correction (CC) ocular sinister (OS) reported both statistically significant with p value <0.001. Both K Max OS and K Max OD are statistically significant. The dry eye was evaluated by using Schimer test with mean of 15.00 and 10.00 with p value <0.001 were found significant.
Conclusion: This study concluded that 62.74% were reported fit and 37.26% were not fit for PRK treatment for refractive error because of the dry eye, Keratoconus, rocotane, amblyopia, hyperopia, diabetics and pregnancy in Aljouf region, Saudi Arabia. The Pentacam Astigmatism and dry eye was found statistically significant in both fit and unfit group.
