age," he says. Six patients asked to have the surgery reversed. Of those
six, four were over 55. "Older patients didn't adapt as well, possibly
because they need a stronger reading prescription, which creates a greater
difference [in prescription strength] between the eyes," he says. "They
also tended to be more satisfied with reading glasses.
"Nobody has demonstrated any significant loss of function
or depth perception," he says. "It's just that some patients feel out
of balance and don't like it."
Maxwell and Caster both emphasize that educating the patient on
what to expect is essential. "The patient must understand that one eye is
for near, one is for far, and the near eye will not be able to see clearly far
away," says Caster. "That's the down side to monovision. It does not
eliminate the need for glasses all the time, but it might reduce the need to
10% of the time."
"We explain that this is a compromise," Maxwell says.
"We're trying to provide [the patient] with the best chance of having some
function without having to put on spectacles. It's not perfect.

well-informed patient. "
