Patient discussion about corneal graft

Q. Has anyone had experience with a corneal transplant because of keratoconus?

A. my uncle had to do a transplant- it took 5 weeks until he could see anything , another year to get his vision straightened up. but now he is fine! i know that he looked for information in the "National Keratoconus Foundation". they were very helpful (and nice!), they have a website with information on all forms of treatment:

good luck :)

Corneal graft failure is one of the most common causes of performing keratoplasty again.1 When vessels are present on the cornea, the chances of graft rejection are very high, and it is considered a high-risk corneal graft surgery.2 This high rate of corneal graft failure in cases of vascularised corneas is because after corneal graft these patients can still develop severe immune reaction against the graft and even immunosuppressive therapy cannot help much in such cases.3
