PRK: Photorefractive Keratectomy - The Original Laser Eye Surgery

Before all the commotion and popularity of LASIK there was another procedure known as PRK or Photorefractive Keratectomy. Although it is an older and outdated procedure, it is still favored by many surgeons to treat specific conditions that traditional LASIK is not suited for like like patients with thin corneas or larger pupils.

Although the FDA approved the first PRK laser in the United States in 1995, the PRK laser was developed in the 80's and has been in use in other countries.

PRK can correct vision for both nearsighted and farsighted people. Nearsightedness is corrected by flattening the steepness in the cornea whereas farsightedness requires the steeper cornea. PRK can also address astigmatism simply by smoothing our the oblong shape of the cornea into a normal one.
