ANALYSIS VERIFICATION SCREEN


Following the digitization, the “analysis 
verification screen” will appear.  It is a 
series of horizontal lines.  For a good 
image on a normal cornea the lines will 
appear straight.  If the image was poor 
and all the points could not be located 
the lines will be jagged.  The lines may 
cross indicating a missed ring.  Missing 
dots on the lines indicate missing data 
points.

Distorted corneas such as with 
keratoconus will result in jagged lines.
