SECTIONAL MERIDIAN PLOT


This plot represents a cross 
section of the cornea with the 
default being the 180 degree 
meridian.  The colors represent 
dioptric changes as indicated 
on the color bar at the bottom.

The meridian of interest can be 
changed by pressing the ‘Up’ and 
‘Down’ keys which will change the 
meridian 10 degrees at a time.  
The ‘PgUp’ and ‘PgDn’ keys change 
the meridians 90 degrees.

Left and right arrow keys move the cursor along a meridian with the value at the cursor point given at the bottom of the screen.
