PRK (Advanced Surface Ablation)
PRK New HampshirePRK or PhotoRefractive Keratectomy, is the original excimer laser procedure which removed or ablated corneal tissue to correct nearsightedness. The surface layer of cells (epithelium) is first removed by one of several methods. The laser treatment is then carried out after which the epithelial cell layer is allowed to heal over the reshaped cornea. Typically, a bandage soft contact lens is applied for 2-3 days to expedite healing and to provide comfort. There is usually a several week waiting period before treating the second eye. Steroid eye drops are gradually tapered over a 3-4 month period. Corneal haze is reduced thanks to the scanning spots of the latest generation of excimer lasers and the use of Mitomycin C in selected cases.

The advantages of PRK over LASIK include the elimination of the potential risks associated with the creation of the flap such as with mechanical failure of the microkeratome during its pass, as well as the late complications associated with the flap itself (such as lamellar keratitis, epithelial ingrowth, slipped flaps, striae and folds).

LASIK rarely requires a bandage contact lens, is much more comfortable, is less likely to cause corneal haze, and does not usually require steroid/ cortisone eye drops beyond 1 week. A successful LASIK treatment depends on the creation of a corneal flap with a microkeratome.

Visual recovery with LASIK is more rapid than with PRK there are situations where PRK might be chosen over LASIK. When the corneal epithelial cells are loose, as with an epithelial dystrophy or corneal erosion, PRK is preferable to LASIK. PRK can also be used to reduce or eliminate superficial corneal scarring, as well as to clear haze from a previous PRK procedure. PRK may also be an option when the residual thickness of the corneal bed after treatment would measure less than the recommended minimum for stability of the cornea. Certain occupations such as law enforcement, fighter pilots, paratroopers are considered to be better candidates for PRK than for LASIK because of the possibility of flap dislocation due to trauma.

Modern PRK has regained popularity with the advent of Wavefront guided ablations, and while the vision takes longer to settle in, it is considered a safer procedure with long term results that are at least as good as with LASIK.
