Laser Eye Surgery Does Not Adversely Affect Cornea in the Long Run
Laser eye surgery that corrects vision does not lead to later problems with the cornea - at least not after nine years, a new study has found.

The technique, called laser ablation, involves removing material from a solid surface by vaporizing the material with a laser beam.

Salvatore Siano and Renzo Salimbeni point out that laser cleaning of artworks actually began about 10 years before the better-known medical and industrial applications of the technique.

Doctors, for example, use laser ablation in medicine to remove unwanted tattoos from the skin.
