Rei,
I had a cataract on one eye last year, and chose the first option, only for
the reason that it is the most mature product, and gives the best clarity.
My other eye is due, and I will again opt for the first option. The third
option could go wrong - a close friend, a captain of industry, who can, and
did, opt for the best that money can buy, both in terms of hardware and
medical advice, is having a tough time because of a snafu, so be careful.
Glasses are a small cross to bear for good vision.
Cheers
Jayanand
