What is Excimer Laser?

“Excimer” is the derivate of the words of excited and dimmer and Excimer Laser is a laser radiating ultraviolet light at 193nm obtained by the stimulation of Argon and fluoride gases. The laser, initially being used in plastic industry and for the production of electronically integrated circuits, attracted the attention of the medicine world due to its precision and started to be used for the first time in 1988 for the myopia treatment over eyes in the United States.

The characteristics of Excimer Laser

If you have read the descriptions regarding the refraction impairment such as myopia or hypermetropia, you may remember that the anteroposterior length of the eye and the changes in the corneal curve result in such situations. The way to eliminate these impairments completely is possible via changing the corneal curve since we are not able to change the length of the eye (at least for now). We are able to perform this by using Excimer Laser which is the most precise lancet invented by the human.

Excimer Laser breaks off the molecular bonds of the corneal tissue performing shaving and gives the cornea a new shape just a sculptor. This process is performed with a high precision. With each touch of Excimer Laser on the cornea 0.25 microns tissue (1/400 of the thickness of strand) is shaved.
