WEBCorneal surface ablation is a procedure where a vision correction surgeon gently removes the epithelium (surface) of the cornea and treats the refractive error on the front surface of the cornea. Corneal surface ablation is an alternative to LASIK that’s also commonly known as photorefractive keratectomy or PRK.
WEBDec 6, 2013 · Introduction. The development of excimer laser ablation represented a breakthrough in the correction of ametropia. Photorefractive keratectomy (PRK) employs a 193-nm argon fluoride excimer laser to ablate the anterior corneal stroma to a new radius of curvature to decrease refractive error.
