Background: Photorefractive keratectomy PRK is a refractive surgery appropriate for subjects with refractive errors who are not eligible candidates for laser in situ keratomileusis (LASIK).Transepithelial photorefractive keratectomy (transPRK) is a subtype of PRK in which conventional alcohol assisted mechanical removal of the epithelium is replaced by excimer laser itself. Postoperative corneal haze is a relatively known complication in both techniques. Objective: To compare between photorefractive keratectomy (prk) and transepithelial photorefractive keratectomy (transPRK) regarding postoperative haze. Patients and methods: This was a prospective study was conducted on 60 patients (120 eyes) of both sexes. Patients were divided into two equal groups. Group A underwent conventional PRK, and group B underwent transPRK. Postoperative corneal haze evaluation was applied for both groups using slit lamp biomicroscopy. Results: No statistically significant correlation, but the incidence and degree of haze in the transPRK group were less than PRK group. Visual acuity was slightly better in transPRK group without any statistically significant difference, too. Conclusion: TransPRK was superior to conventional alcohol assisted PRK especially in moderate and high myopia.
