| Summary: |
The article summarises the
question of using corneal topography particularly the
Orbscan II slit scanning system in examining patiens
before laser refractive surgery (PRK, LASIK, LASEK)
especially evaluating the risk of postsurgical ectasia,
in performing the procedures of customised ablation, in
analysing the outcomes and diagnosing complications.
Essential for carring out the procedure safely is
carefull patient qualification focused on finding signs
and symptoms which could be contraindications for laser
refractive surgery. Special attention has to be paid to
early (or forme fruste) keratoconus. Orbscan II turns
out to be very usefull for all mentioned above purposes.
Nevertheless other methods of evaluating the shape of
the cornea in sense of ruling out early keratoconus are
also described. These are mainly numerical indices known
as Rabinowitz’s method, Klyce/Maeda method or KISA%
index. The authors present also the figures with
examples of Orbscan II examination results with broad
comment. |
