I had one eye done about 7 years ago and it was fine, it doesn't hurt, and they usually give you a sedative if wanted - as others have said on here, I couldn't believe how bright the colours were! Make sure you do the drops religously, and don't rub the eye - on the second day after the op. my eye felt a bit gritty, and it was murder trying not to rub it. My other eye has a cataract too, but developing very slowly, but will have to come out one day. But fotunately the op is so easy that I'm not worried, and I'm the world's biggest coward! Good luck in any case.
