Laser Vision Correction
Laser Vision Correction is the general term used to describe the reshaping of the human cornea using the cool gentle and precise light energy of the excimer  laser.

The Excimer laser generates its ultraviolet laser energy by stimulating a combination of argon and fluorine gases. Each pulse of the laser is capable of breaking carbon bonds within corneal tissue and vaporizing approximately 1/4 of a micron of corneal tissue in 12 billionths of a second. The dose of laser treatment is computer controlled, and is based on the amount of refractive error. A person whose eyeglass prescription measures -4.00 diopters would require approximately 50/1000ths of a millimeter (50 microns) of corneal ablation (flattening). A human hair is approximately 125/1000ths of a millimeter (125 microns) thick !

In contrast, Radial Keratotomy or "RK" required radially placed incisions around the central optical zone of the cornea. This resulted in weakening of the structural integrity of the eye as well as undesirable visual side effects such as starbursts and fluctuating vision. RK was less accurate in correcting refractive errors, and microperforations of the cornea would sometimes occur whenever corneal thickness was overestimated.

In the early 1980's, the excimer laser was being used in industrial application for etching computer chips. It was discovered that the energy from this laser could break up carbon=carbon bonds in molecules of corneal tissue, and remove very small and precise amounts without producing thermal damage to the adjacent corneal tissue. This was the foundation of laser vision correction, the ability to reshape the cornea with the excimer laser to compensate for refractive errors. The two procedures in use are PRK and, more commonly, LASIK.
