I have had Yag laser capsulotomy done several years ago, and the drops they put in the eye to make the pupil bigger, and a anaesthetic eye drops to numb the surface of the eye were no problem apart from the initial sting.
I had no pain at all in the eye while the procedure was done, but paying for it was painfull,
No, I've had the treatment several times and just sit in the normal eye test chair. They ask you to look at an area of the room. I think they used an eye clip to stop blinking but can't say I noticed it at all.
