This is kind of a spin-off of HappyLady's post below regarding her Davis Lab.
I noticed that the patient wanted a 2mm drop instead of a 4mm drop, and that got me thinking.
I had always guessed that the "drop" had to do with the relative locations of the laser marks and the fitting cross. I never thought that the drop would affect vision at all (as long as the lens was still fit properly for the right drop).
Can someone shed some light on this one? What difference does it make to the patient looking through the lenses?
