What happens if a corneal transplant fails?

A patient with a corneal transplant rejection may experience discomfort or pain in the eye, redness, blurred vision and watering. The seriousness of such a rejection depends on the type of transplant that was carried out.

Why would a transplanted cornea be rejected?

Rejection happens when your immune system recognises the donated cornea as not belonging to you and attacks it. It’s quite a common problem, with symptoms of rejection occurring in about 1 in 5 full-thickness corneal transplants, although only about 5% of low-risk grafts actually fail because of this.

How common is corneal transplant rejection?

The incidence of rejection is greatest in the first year-and-a-half following transplant but can occur up to 20 years or more after surgery. Guilbert et al reported an average keratoplasty-to-rejection time of 19.8 ± 20.4 months (among 299 patients who experienced a rejection episode).

How long does a second cornea transplant last?

It is a highly successful operation: when performed by an experienced corneal surgeon, graft survival rates are over 90% after 10 years and the average life of a transplant is around 15-20 years.

Can a corneal transplant be redone?

A corneal transplant can be repeated, usually with good results. However, the overall rejection rates for repeated transplants are slightly higher than for the first transplant.

Can corneal transplant rejection be reversed?

The rate of reversal in severe endothelial rejection is as high as 60% when appropriate therapy is initiated. This initial therapy is essential in high-risk patients, and may vary depending on the clinical findings.

What are signs of corneal transplant rejection?

Why are so many cornea transplants being rejected?

A recent study showed that some transplanted corneas are rejected because patients fail to comply with medication instructions after surgery. Corneal transplant rejection is generally reversible, and if addressed quickly, may not impact negatively the function of the transplanted cornea.

Can a cornea be transplanted with a donated cornea?

Corneal transplantation, or keratoplasty, replaces a severely damaged cornea with a donated one. Corneal transplantation can involve replacing the entire cornea or select parts of the cornea depending on the location of the damage.

When do you need a cornea transplant to restore your sight?

Conditions that might require corneal transplantation include: If the damage to your cornea is minor, you may not need corneal transplantation.

Can a corneal transplant be reversible or irreversible?
