Not long after RK, or radial keratotomy, came a new technique for shortening the focal length of the nearsighted eyeball. This was the long awaited PRK, photorefractive keratotomy. The procedure reshapes the cornea, in effect, shortens the focal length. A laser with low-heat UV radiation removes corneal material literally microscopic layers at a time. The procedure is robotic; the laser is pre-programmed, literally vaporizing a few molecules with each pulse from just the right place on the corneal surface.

LASIK eye surgery is a complex surgical procedure that can take only a few minutes to yield exceptional results. The speed and accuracy of the procedural is a major reason why this type of eye surgery is fast becoming one of the most requested surgical procedures. The fact that most patients who undergo LASIK eye surgery generally feeling no pain is another major reason why it is so sought after. There are dangers with every surgical procedure and LASIK eye surgery is no different, there are many risks to the surgery and many complications that can arise.
