COMPUTERIZED VIDEOKERATOSCOPES
WHAT DO THE MAPS TELL US?
Photorefractive Keratectomy (PRK)
Photorefractive keratectomy
cases (PRK) for treatment of
myopia also result in a flat
central area which is obvious
on the corneal map. These
instruments are useful in
determining the uniformity of
the changed area, the size of
the affected area and any
changes that occur over time.
