Cornea Transplant Risks and Complications

Cornea transplant is a relatively safe procedure. Still, it does carry a small risk of serious complications, such as:

. Eye infection

. Increased risk of clouding of the eye's lens (cataract)

. Pressure increase within the eyeball (glaucoma)

. Problems with the stitches used to secure the donor cornea

. Rejection of the donor cornea

. Swelling of the cornea

. Bleeding from the eye

. Fluid leakage from your cornea

. Detached retina (tissue lining the back of the eye pulls away from the eye).

. Visual acuity problems (sharpness of the vision) caused by an irregular curve in the shape of the cornea.

. Detachment of the corneal transplant (for the endothelial transplant which is held in place by an air bubble).

Signs and symptoms of cornea rejection

In some cases, your body's immune system may mistakenly attack the donor cornea. This is called rejection, and it may require medical treatment or another cornea transplant. Rejection occurs in about 10 percent of corneal transplants.

Make an appointment with your eye doctor if you notice any signs and symptoms of rejection, such as:

. Eye pain

. Sensitivity to light

. Red eyes

. Cloudy or hazy vision

Below are some factors that could increase the risk of tissue rejection.

. The donor cornea

The main factors that affect donor tissue rejection are human leukocyte antigen (HLA) incompatibilities and blood type incompatibilities.

HLAs are a set of proteins in the body that regulate the immune system.

The type of antigens and antibodies that make up a person’s blood determine their blood type.

If the donor HLA or blood type is incompatible with those of the recipient, the recipient is more likely to reject the donor tissue.

. Health of the recipient

Certain preexisting conditions can increase a person’s risk of an immune reaction. Some of these conditions include:

. Herpes keratitis, which is a viral infection of the eye

. Uveitis, or inflammation of the structures in the middle of the eye

. Atopic dermatitis, which is a chronic inflammatory skin condition

. Age of the recipient

According to a 2017 review, younger people are more likely to reject a cornea transplant, compared to older people. This is partly due to the fact that younger people tend to have more robust immune responses.

10 common question about cornea transplant complication

1How successful is a cornea transplant?
Cornea transplants are performed routinely and have a reasonable success rate. In fact, cornea grafts are the most successful of all tissue transplants. ... Rejection of the donor tissue is the most serious complication after a corneal transplant and occurs in 5 to 30 percent of patients.
2How long does it take to recover from a corneal transplant?
6 to 12 weeks Your vision may be blurry for a period of time after surgery. For some people, it may take 6 to 12 weeks to get the full benefits of surgery and to see as clearly as possible. Your doctor will give you eyedrops to help your eye heal and prevent your body from rejecting the donor tissue.
3Do corneal transplants last forever?
Some corneas do last forever, but some need to be replaced due to transplant rejection (which can occur even 20 years later) or due to simple failure of the transplant's new cells over time (depending on the age and health of the donor tissue, the “warranty” may just run out).
4Why would someone need a cornea transplant?
Why the Procedure is Performed A corneal transplant is recommended for people who have: Vision problems caused by thinning of the cornea, most often due to keratoconus. (A transplant may be considered when less invasive treatments are not an option.) Scarring of the cornea from severe infections or injuries.
5Can you go blind from a corneal transplant?
A corneal transplant involves replacing a diseased or scarred cornea with a new one. When the cornea becomes cloudy, light cannot penetrate the eye to reach the light sensitive retina. Poor vision or blindness may result.
6Is corneal transplant permanent?
Most people who have a cornea transplant get at least part of their vision restored, but each situation is different. It could take a few weeks and up to a year for your vision to improve fully.
7is corneal transplant surgery painful?
During the procedure You won't be asleep during the surgery, but you shouldn't feel any pain. During the most common type of cornea transplant (penetrating keratoplasty), your surgeon cuts through the entire thickness of the abnormal or diseased cornea to remove a small button-sized disk of corneal tissue.
8How soon can I drive after a corneal transplant?
If you have good vision in the non-transplant eye, you can legally drive 24 hours after surgery. However, your surgeon may recommend waiting longer before driving.
9Why do cornea transplants fail?
Corneal Transplantation Failed. ... Failure can occur for a number of reasons, the most common one being endothelial decompensation, either due to graft rejection or "endothelial exhaustion," where enough of the endothelial cells die off and the cornea becomes edematous.
10Can you have a second corneal transplant?
And for those that do require a second transplant, the incidence of long-term immune rejection goes up to almost 70 percent. ... The good news is that drugs can be administered to block SP and restore the eye's immune privilege, potentially increasing the success rate of second corneal transplants.
