COMPUTERIZED VIDEOKERATOSCOPES DATA DISPLAY


Holladay Refractive Maps (EyeSys system)

This diagnostic series 
gives the refractive data 
on a standard color map, 
an autoscaled map, a 
profiled difference map 
(dioptric difference in 
different zones) and a 
distortion map which 
predicts the optical 
quality of the surface 
and gives the expected 
Snellen visual acuity 
equivalents.
