[The treatment of myopia by photoreactive keratectomy (PRK) with the 193-nm excimer laser].
Excimer laser photokeratectomy is the most recent procedure used for correcting myopia surgically. It consist in flattening the cornea by performing ablations of a part of its anterior stroma. Over 15,000 patients underwent this almost entirely robotic surgical intervention, supposed not to present the shortcomings of radial keratotomy. This robotic surgery tend to replace radial keratotomy. Photokeratectomy is designed to correct all kinds of myopia, astigmatism as well as these resulting from such surgical interventions as cataract extraction or Keratoplasty. A bifocal photorefractive keratectomy is expected to correct the myopia of the patients who reached the age of presbyopia.
