PRK, or Photorefractive Keratectomy, is a procedure that differs from LASIK because it does not involve the creation of a corneal flap. Instead, the Excimer laser beam is applied directly to the surface of the cornea. By eliminating the flap creation step, the risk of flap complications is eliminated allowing for an effective and precise correction.
The PRK procedure works by reshaping the cornea of your eye with millions of precisely controlled laser pulses to correct farsightedness, nearsightedness, or astigmatism. Refractive errors can be corrected in just seconds of this short procedure.
