I had it done in the Blackrock Clinic (Prof Louis Collum) about a year and a half ago. I am extremely squemish and can't even look at hypodermic needle without feeling sick, but I found the eye op fine. It is a little uncomfortable, but that's it.
I would urge anyone thinking about it to attend an experienced surgeon. It is not something you should scrimp on or take risks with.
I am delighted with the operation, despite two side effects; I have to use drops in the morning when I wake up (artelac, cost aprox 4.50 a month) and when using a computer as my eyes feel a bit dry; also when driving at night on unlight roads oncoming traffic can cause glare, luckily I don't do this type of driving much, so it's not a big deal.
I would have the op again tomorrow if I had to.
