The process of recovery from Corneal Graft Procedure is slightly different from other major surgeries. The differences arise because of the unique nature of the cornea.
It receives all its nourishment from aqueous humor (the watery fluid in the eye) there are no blood vessels supplying blood to the organ. Thus, the rate of recovery is much slower than any other organ.
A major issue that arises during the recovery process is the high risk of infection. Since the cornea heals very lowly, the long recovery period makes it very susceptible to infection from a range of bacteria. To avoid this, the patient is placed on a long regime of antibiotics, both oral and eye drops. The aim of this regime is to keep the cornea health and infection free.
An important aspect of the recovery process is the threat of rejection of the transplanted cornea. The rejection rate is rather low in the case of corneal transplant and stands at 20%.
Bleeding is very rare because of the absence of blood vessels.
Leakage of fluid from the incisions is a common complication of the operation. As the incisions heal, this issue is resolved.
There is a chance that the operation could result in damage to other parts of the eye. However, this is very rare in the hand of a good surgeon.
Finally, given the long healing process, it is common to see patient suffer from these issues for well over a year after the original operation.
