Ultraviolet laser radiation is well absorbed by biological matter and organic
compounds. An ultraviolet laser adds just enough energy to such material to disrupt
the molecular bonds of the surface tissue, which than disintegrates into the air in a
process called ablation. Thus ultraviolet lasers can remove exceptionally fine layers
of surface material with almost no heating or change to the remainder of the material.
These properties make ultraviolet lasers well suited for delicate surgeries such as
eye surgery, also referred to as LASIK (laser-assisted in situ keratomileusis).
Wavelengths of ultraviolet lasers vary from 337 to 126 nanometers so it covers the
complete range from UV-A through UV-C. Eye surgery may only be executed by a
