James,
I have posted my experience of the operation here:
http://www.keratoconus-group.org.uk/for ... php?t=2769, and although it might seem like a nightmare post op, I have no regrets and even though it's early days, I have had a fairly significant improvement in my vision, having gone from not being able to see the first line unaided to 4 lines plus 2 unaided the morning after the op.
I am merely unfortunate in the fact that I managed to get an infection. Each individual will almost certainly have differing experiences post op both in the terms of comfort and visual acuity. I already know that I will still be wearing glasses for the rest of my life as am contact lens intolerant, but at least for the right eye the lens will now be a lot thinner.
Like your consultant, my consultant Mr Kaye, was performing the procedure for the first time last Thursday, and is a very experienced corneal surgeon. I would say have faith in your consultant's ability.
