Cornea transplant complication

Risks-Cornea transplant

 One of the most concerning complications of cornea transplant is organ (cornea) rejection. Rejection means your body’s immune system identifies the donated cornea as foreign and tries to fight off the transplant. You will take eye drops for at least a year following surgery to reduce the risk of rejection.

Risk of rejection varies based on the surgical technique used and on the condition of your eye. Conditions like dry eye, blood vessels growing in the cornea, and eye infections increase the chance of rejection. In some eyes, a transplant will have a very high risk of rejection and your surgeon may recommend against surgery. Ask your doctor how the condition of your eye affects the chances of rejection.

As with all types of surgery, there are several risks and possible complications involved with having a cornea transplant.

Some problems are obvious soon after surgery and need emergency treatment. Others may be spotted during follow-up appointments.

Rejection

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.

Serious rejection is rare after deep anterior lamellar keratoplasty (DALK).

Rejection can occur a few weeks after a cornea transplant, but it's more common after several months.

The problem can often be treated effectively with steroid eye drops if treatment begins as soon as you notice symptoms.

You should seek emergency specialist advice if you notice these symptoms after having a cornea transplant:

  • red eye
  • sensitivity to light (photophobia)
  • vision problems – particularly foggy or clouded vision
  • eye pain

Other complications

As well as rejection, there's a risk of further problems after cornea transplant surgery.

These can include:

  • astigmatism– where the cornea is not a perfectly curved shape
  • glaucoma– where pressure builds up in the eye as a result of trapped fluid
  • uveitis– inflammation of the middle layer of the eye
  • retinal detachment– where the thin lining at the back of your eye called the retina begins to pull away from the blood vessels that supply it with oxygen and nutrients
  • the original eye disease (such as keratoconus) returning
  • wounds from surgery reopening
  • internal infection as a result of surgery wound

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.
