| I'll probably be having cataract surgery soon. I have an appointment with an
opthamologist in a few days. I have been reading about the multifocal
lenses on the internet. I was wondering if anyone here has first hand
experience with these lenses and could give me an idea of how my vision
would be. It looks like there are two choices of multifocal lense, the
array and the crystalens. Is this correct? What are the advantages and
disadvantages to these two IOLs? From what I gather, the crystalens has
some sort of "hinge" and it moves to provide focus for near and far. I'm
not sure how the array lens works. It sounds like it allows you to focus
near and far at the same time. How does this work? I read somewhere that
your brain has to learn how to focus with these lenses. Is this a problem?
I'm sure my opthamologist will be able to answer these questions but I
would like have as much knowledge as possible when I see him.

The first kind works like multifocal contacts. I would strongly suggest
that you try multifocal contacts first. If your brain can't handle them,
then it probably won't be able to handle the IOL either. The second kind
is very new, and I for one wouldn't want to be the guinea pig for it.
There are a million cataract surgeries a year in the US, and so it's
pretty routine. I've had cataract surgery in both eyes, and I'm happy to
have the ordinary IOL, set for distance. I've had to deal with reading
glasses for many years now, and it just doesn't bother me much.

That's a very good idea. You will have to make some choices that you will
probably have to live with for the rest of your life.
