COMPUTERIZED VIDEOKERATOSCOPES DATA DISPLAY
At least one instrument (Orbscan)
determines the corneal topography
by digitizing a series of light slits
(optic sections) across the cornea.
This technique has the advantage of
being able to make measurements
from limbus to limbus, to determine
the corneal thickness of the whole
cornea and to give the back surface
geometry. The elevation at each
point of the cornea is determined.
