As others have said, inserting replacement lenses is now a routine
operation with a very high success rate. I do not have direct
personal experience of this but provided transport for my wife to and
from hospital for her operations about a year ago. The two eyes were
done about two months apart and in each case we were in and out the
hospital in less than 3 hours with follow up visits the next day and
some time later. Within days of the first operation, she found
driving much easier than before because road signs were easier to read,
and this was clearly apparent from the passenger seat!
If you follow this precedent, Brian,and as someone who looks carefully
at things when taking photographs, you may be surprised to find in the
interim period that some objects look different colours depending on
which eye is being used! In our case, it was a dark green cardigan of
mine which looked blue with one eye and green with the other. Possibly
not too surprising as I understand a cataract can act as a yellow
filter. But I am not sure what the view of professional Philosophers
is on this since in my experience there is a tendency for tutors at an
introductory level to regard an object's colour as an absolute
characteristic of the object, and have enough difficulty coping with
arguments about the effects of different ambient lighting.
But one piece of advice, be careful for a while after the operation and
try not to have an accident like one friend recently who went water
skiing too soon afterwards and suffered a bad fall.
