A friend of mine said that lenses implanted during cataract surgery
have had a history of problems with getting cloudy over time due to
protein buildup on the lenses. Is this still a problem with modern
IOL materials? Do implanted lenses have the same problem with protein
buildup as contact lenses? If so, how long does a person have after
cataract surgery before vision is blurry again? If this is no longer
a problem, how long has it not been a problem? What kind of material
does an IOL need to be made of to resist protein buildup? Are modern
IOL's coated with a nonstick coating? Which brands of IOL's resist
protein buildup the best?

Thanks in advance!

That'll teach you to get advice from friends! You are making a mountain
out of a molehill. I have never, ever heard of this. I have two IOLs,
one in each eye. One has been there a decade. My surgeon said that
they are permanent, and never need replacement, in general. There is no
concept of protein buildup.

Having said that, the lens capsule often clouds up after IOL placement,
usually within a year. Fixing it is an office procedure, and takes
about five minutes with a laser. That also is permanent, and is only
done once per eye per life, if ever.
