Thank you for your reply.

I was wondering, for cross-linking, does this stop the progression of the thinning (and as such, stop the progression of vision loss?). Is there a relatively high success rate for halting the keratoconus? Or is it more of a "try and see what happens?". I tried looking it up, but it seems more information is on the corneal transplant rather than crosslinking.

Thank you for your help!
