I agree, Glenn. When I see an unhappy post-op LASIK monovision
patient, they always look at me like I'm from another planet when I
ask them if they tried monovision in contact lenses before they had it
lasered into their eyes. Trial fitting MUST BECOME a standard of
care.
Incidentally, I have stumbled upon a "new" way to explain monovision.
I mention to the patient that his/her brain is always making choices
between the two sides of the body that they never "think" about. For
example, if you approach a curb and have to "think" about how to step,
you could simply fall while deciding. So, you simply step with your
"favorite" foot.
When monovision works, the brain decides at a subconscious level to
use both pictures simultaneously and share the best of both sides,
picking one when it "has to."
This is consistent with the work of Dr. Jan Jurkus from the Illinois
College of Optometry, who has shown that people who have total
"one-handedness", as if the second half of their body can't catch
anything, are very poor monovision wearers. Their brains don't want
to share the picture from side to side, as they have never done so for
anthing else.
