| Abstract | ||
| Myopia is a major global problem for vision and blindness, according to the World Health Organization Refractive surgery, which corrects ametropia, has changed a lot over the years and become one of the most common medical procedures. The first surface ablation procedure (corrective eye surgery) to use a laser instead of a blade to remove the corneal tissue was Photorefractive Keratectomy (PRK) By reshaping the outer epithelialized surface of the cornea, PRK uses excimer laser ablation to correct ametropia with up to 6 D of myopia, around 3 D of astigmatism and low–moderate hypermetropia. Removing of the epithelium in (PRK) was performed by several techniques includingconventional PRKwhich include mechanical and chemical methods , and by the excimer laser itself, which is called transepithelial PRK where the epithelium is removed by an excimer laser instead of alcohol and manual scraping. AIM OF THE WORK: The aim of this work was to compare visual and refractive outcomes between conventional PRK and transepithelial PRK in the treatment of mild to moderate myopia. | ||
