====Photorefractive keratectomy====
{{see also|Photorefractive keratectomy}}
Photorefractive keratectomy (PRK) involves ablation of corneal tissue from the corneal surface using an [[excimer laser]]. The amount of tissue ablation corresponds to the amount of myopia. While PRK is a relatively safe procedure for up to 6 dioptres of myopia, the recovery phase post-surgery is usually painful.<ref>{{cite journal | vauthors = Trokel SL, Srinivasan R, Braren B | title = Excimer laser surgery of the cornea | journal = American Journal of Ophthalmology | volume = 96 | issue = 6 | pages = 710–5 | date = December 1983 | pmid = 6660257 | doi = 10.1016/s0002-9394(14)71911-7 }}</ref><ref>{{cite journal | vauthors = Seiler T, Bende T, Wollensak J, Trokel S | title = Excimer laser keratectomy for correction of astigmatism | journal = American Journal of Ophthalmology | volume = 105 | issue = 2 | pages = 117–24 | date = February 1988 | pmid = 3341427 | doi = 10.1016/0002-9394(88)90173-0 }}</ref>
