Function: treatment of far-sightedness.
A holmium laser treatment can correct different kinds of visual defects.
The Excimer-Laser-Clinics in Blaubeuren were among the first German institutes
to use a excimer laser for treatment of such cases. The excimer laser works
by sending a smooth warmth onto the cornea. Its intensive light rays enter
the basic tissue outside the pupil area at four or eight points, or a multiple
of it. This changes the size and light-refracting properties of the cornea
(e.g. after cataract surgery). In cases of presbyopia, the excimer laser produces
a sort of minimum near-sightedness, so that it may no longer be necessary
to use "reading-glasses" - or at least the need for such glasses
is reduced considerably. In many cases, vision is improved after this kind
of treatment.
