I'm potentially facing a cornea transplant, I've read pretty much everything you can read on the subject, I've also been to several opthamologists in Calgary and have asked many, many questions.
How did your corneas scar? I presume wearing RGP's fitted to correct keratoconus?
You will see the success rate touted as being as high as 95% and as low as 80%. The "failures" are usually due to tissue rejection. The older you are, the less likely your immune system will reject the tissue.
Cornea surgery is the easiest of all transplants, and does not require matching for blood type.
A big potential problem is typically fitting contact lenses after the surgery, assuming you'll still need them.
If the sugery is successful, you will see fine. The results post-op are often a dramatic improvement in vision, though it can take a year of healing before you get to the final results.
PM me the name of your opthamologist.
If you want really good information, search google for "keratoconus message board" and you'll find there is a wealth of information available.
