Papang - welcome to the club! A small, exclusive and somewhat shortsighted group. In fact, with that in mind....
Here is a link to a good explanation of corneal crosslinking with riboflavin(C3-R)
[http://www.keratoconusinserts.com/images/pdf/C3-RforKC.pdf
The reports seem to be very good in terms of halting k/c progression and in some cases reversing the effects to some extent. I wish it had been around 25 years ago when I had my treatment - corneal grafting. It went extremely well and I have 6/6 vision.
Anyway, SebastianRys and Jolly Roger should be in a better position to let you know about the treatment as they have (or will have) undergone the procedure, whereas I haven't.
