The-Lasik-Directory.com Tip: Photorefractive keratotomy, also known as PRK, is a form of laser eye surgery in which the cornea is reshaped via the beam of an ultraviolet light used on the surface of the cornea. This is in contrast to traditional LASIK in which the infrared laser is used below the surface of the cornea. This difference yields some advantages to this type of procedure.
The advantages of PRK laser eye surgery include no potential for complications which develop as a result of cutting or reattaching the corneal flap, the use of less corneal tissue, the procedure is quicker than LASIK and the cost associated with PRK is typically lower than the cost associated with LASIK surgery.
