There are two different types of lasers used in laser eye surgery. The actual vision correction of LASIK which is done under a flap, or PRK which is done on the surface of the eye after removal of the skin of the eye is an excimer laser. This is a short wave ultraviolet laser with a wavelength of 193 nm. It works by short pulses that break carbon carbon bonds on the surface of the eye. Typically this laser removes about 0.3 microns of tissue with each pulse. Therefore to remove the amount of tissue to correct most patients hundreds of pulses in the same spot are needed. Modern excimers use small laser spots of only about 1 mm in diameter and therefore to treat the area of a 6 mm treatment diameter can take thousands of laser spots. Fortunately these lasers run at a rate of from 100 to 400 Hz and can accomplish this in less than a minute. Infrared eye trackers are used to monitor the position of the eye, usually relying on the pupil or iris to track movements and to deliver the treatment in the correct location.
Another laser that is also used is the femtosecond laser which can make a corneal flap. This is an infrared wavelength laser which sends very small pulses about a micron in diameter to a specific focal point causing optical breakdown and tissue separation by that mechanism. Here the laser operates at a higher frequency so that up to millions of spots are created to separate the outer cornea from the deeper tissue, creating a flap of superficial tissue which is lifted up to allow the first laser mentioned to do the correction and then the flap is returned to its original position which can heal quickly and with minimal discomfort. This is the primary reason that LASIK is so much more popular than PRK, where in the latter case, a new skin must heal over the treated area which is uncomfortable for a few days and the visual recovery is much slower.
