Doctors have been routinely treating nearsightedness, farsightedness and astigmatism with incisions for over 25 years. By the early 1980s, they began looking at lasers to improve the precision and predictability of altering the shape of the cornea. Researchers found that IBM's new Excimer laser, used initially for etching computer chips, had medical applications as well. Now in its second decade of use, the technologically-advanced Excimer laser has added a tremendous amount of precision, control and safety to treating nearsightedness, farsightedness and astigmatism.
Its ability to remove corneal tissue with accuracy up to 0.25 microns (0.00004 of an inch) with each pulse makes the Excimer laser well suited for correcting vision. Often, only 50 microns of tissue (about the thickness of a human hair) are removed to achieve the proper amount of correction.
The Excimer laser produces a "cool" or non-thermal light beam as most of its heat is dissipated into the air. This makes it ideal for corneal surgery because it eliminates the possibility of thermal damage to surrounding tissue.
