APEX VERIFICATION


The screen seen following the taking 
of the photo shows a profile of the 
cornea.

The red square should be on the edge 
of the apex.  If it is, click on the 
accept button.

If the red square is off the edge of 
the apex you should correct it by 
clicking on ‘edit’. Place the cursor 
on the red square, hold down the left 
mouse button and move the red 
square until it just touches the apex.  
Release the mouse button. Click on the 
accept button.
