Vision problems resulting from refractive error (nearsightedness, farsightedness, and astigmatism) have long been corrected with eyeglasses or contact lenses. While these methods can produce clear vision, eyeglasses and contact lenses are often considered a hassle. There are two exciting ways in which the excimer laser can surgically dramatically improve vision, utilizing the same principles that allow eyeglasses and contact lenses to produce clear vision: PRK, or Photorefractive Keratectomy, and LASIK, or Laser Assisted In-Situ Keratomileusis.

Before PRK or LASIK, patients receive powerful numbing drops so that they do not feel any pain during the procedure. In PRK, the excimer laser allows the surgeon to reshape the surface of the cornea using pulses of light emitted from the laser. During LASIK, the surgeon uses a highly sophisticated computer - assisted instrument called a microkeratome to gently create a super-thin flap across the surface of the eye.

The powerful numbing drops administered prior to the procedure ensure that patients do not feel any pain during the procedure. The hinged flap is folded back, the excimer laser and microaeratome is used to reshape the underlying tissue. Following laser treatment, the flap is laid back in place. Both PRK and LASIK are effective procedures for correcting refractive errors.

Although some surgeons prefer to perform PRK, and in some cases PRK may be better suited for a particular patient, most doctors favor LASIK now due to increased patient demand, faster visual recovery, and fewer post-operative visits. The following chart highlights some comparative information for the two procedures.
