PRK has been studied since the 1980s 1, 2 and has been proven to be predictable, effective and safe in the treatment of low to moderate myopia, hyperopia and astigmatism. In this procedure, the ultraviolet beam generated by a 193nm argon fluoride excimer laser is irradiated to the corneal stroma, after epithelium removal, to reshape the anterior corneal stroma by photoablation and correct the ametropia. Photorefractive keratectomy (PRK) was the first type of surface treatment introduced. Surgical procedures that involve operating on the cornea using an excimer laser are known as laser vision corrections and include two main procedure groups: laser-assisted in situ keratomileusis (LASIK) and surface treatments. Surgical treatment is another option and aims to overcome some of the limitations of spectacles and contact lenses, such as glasses being uncomfortable and not being practical for playing sports, and contact lenses being associated with corneal infections.
