Laser eye surgery relies on various modes of technology to deliver
the outstanding results available today. The most important aspect
is the laser itself. In the early days of laser eye surgery, the
laser had a ‘broad beam’ that covered the entire surface that was
being treated all at once. Thankfully, most clinics no longer use
this type of laser. For more information on the lasers in use,
please see laser technology.
When having the LASIK procedure, a flap is created typically using
a Microkeratome. These instruments were quite complicated when
LASIK first started, but the Microkeratomes have been refined over
the years and have drastically reduced the potential for
complications.

Prior to the laser procedure there are various tests that are
performed to determine your candidacy for laser eye surgery.
Wavefront Aberrometry is used to determine how sharply images are
focused inside your eye. If there are any spots that lack clarity
(aberrations), then a customized wavefront treatment can be done.
Other specialized tests done include corneal topography maps.
These maps are useful in detecting some types of corneal pathology
that would otherwise not be found. The presence of pathology may,
or may not, eliminate you as a candidate for LASIK or PRK.
