HOLLADAY DIAGNOSTIC ANALYSIS
This display shows the refractive power of the cornea instead of the curvature which the previous maps indicated. A summary table at the bottom of the screen gives details about the cornea.
The top two maps use SnellenΓÇÖs
law to determine the power
over the corneal surface
displaying the results on an
absolute scale and a
normalized scale.
