Rather it adds sufficient energy to disrupt the molecular bonds of the surface tissue which, then, disintegrates into the air through ablation and not through burning.
Laser ablation is a highly controlled procedure that can remove exceptionally fine layers of surface material without either heating or otherwise affecting the rest of the material which is rendered totally safe as the excimer laser acts upon it.
In fact, the excimer laser is an ultraviolet chemical laser employing a combination of one of the inert gases like argon, krypton, or xenon and one of the reactive ones like fluorine or chlorine.
When this mixture is electrically stimulated under appropriate conditions, a dimer is created.
A dimer is a pseudo-molecule, which can only exist in an energized state and can give rise to laser light in the ultraviolet range.
The excimer laser that we get through this process is a very well focused, highly controlled, cool beam that is not at all harsh on biological matter.
Hence it suits the procedure of laser eye surgery the best.
