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.
