Are all Excimer lasers equally
good? |
Excimer1 lasers play
an important part in eye surgery. Not all lasers are
the same and presently the older lasers (first and second-generation),
which are broad-beamed, are less accurate, exposing
patients to more risks. The best lasers at present are
the scanning lasers, which gently spread a purified
beam of laser energy in small pulses over the cornea,
resulting in a smooth ablation surface.
The latest generation of lasers e.g. Wavelight Allegretto
Eye-Q Laser can perform standard, wavefront guided,
wavefront enhanced, topography guided and aspheric /
Q-adjusted LASIK.
