Question

A cornea transplant involves the grafting of a donor cornea into a recipients anterior eye the structures to hold the graft in place must stay in place for a long period of time because the cornea is slow to heal explain why the healing process is so slow and also why graft rejection is unlikely with a cornea transplant?

Answer 1

Answer:

The cornea is an avascular tissue.

Explanation:

Since the cornea doesn't have any blood vessels the body's immune system is less likely to detect the foreign graft, and therefore, rejection is unlikely (although possible).

For the same reason, the lack of blood vessels that carry oxygen and nutrients will greatly slow the healing process. That is why this transplant can take so long to heal. For most people, it can take between 6 to 12 weeks to fully recover from the surgery.
