\r\nBackground\r\nCorneal refractive surgery is rapidly evolving, and several surgical techniques have been developed, including transepithelial photorefractive keratectomy (trans-PRK).\r\n\r\n\r\nAim\r\nTo assess the impact of trans-PRK on visual acuity (VA), contrast sensitivity, spherical aberration, tear stability, corneal surface and thickness.\r\n\r\n\r\nSetting\r\nThe study was conducted in Saudia Arabia, Al Madinah Almunwrah, Eye Specialist Center.\r\n\r\n\r\nMethods\r\nA quantitative, comparative, and prospective case study was conducted. Eighty-six consenting volunteers aged between 18 years and 40 years, including both genders, were enrolled in the study. Participants were grouped according to the time they presented after surgery. The Statistical Package for Social Sciences (SPSS) software version 27 (IBM Corporation) was used for descriptive and comparative data analysis by applying one-way analysis of variance (ANOVA) and paired t-tests.\r\n\r\n\r\nResults\r\nThere was a significant increase in contrast sensitivity (P
