Cases that require a corneal transplant … and its complications


The cornea is equivalent to two-thirds of the visual power of the human eye, in addition to being responsible for the focus and refraction of light that enters the eyes. Although the cornea is strong, it is a very thin part of the eye, making it vulnerable to damage.

Cornea transplants help restore vision, in case it is damaged and vision problems develop. But when do you need to consult a specialist doctor?

Cases requiring operation

An ophthalmologist may advise you to undergo the operation if you suffer from eye pain, blurred vision, or vision loss due to various diseases, including keratoconus or Fuchs’ disease (corneal dystrophy).

Patients who suffer from corneal thinning, corneal scratches, opacities, swelling, corneal ulcers, or any complications caused by previous eye operations, can also benefit from the operation.

In addition to the above, diabetes is one of the most common diseases in the MENA region, and it increases the risk of patients suffering from corneal damage. This is due to the recurrence of the corneal occurrence caused by diabetes, including delayed healing of membrane wounds, ascites, repeated erosion, neuropathy, loss of feeling in it, changes in the tear film, in addition to delayed diagnosis of complications of type 1 and type 2 diabetes.

The most prominent complications of the operation

One of the most alarming complications of a corneal transplant is corneal rejection, that is, when the body’s immune system attacks the transplanted cornea and considers it a foreign body.

The possibilities of corneal rejection vary according to the method of transplantation used in the operation, as an implant that repairs the cornea with a full thickness has a greater risk of corneal rejection.

Also, some health problems such as dry eyes, high pressure of blood vessels in the cornea, eyelid problems and eye infections all increase the chances of rejection of the transplanted cornea, and for this reason, medicinal eye drops must be prescribed to help maintain its integrity.

Other complications of corneal transplantation include infections, glaucoma, eye bleeding, problems with visual acuity, fluid leakage from the cornea, corneal detachment, and others.

Corneal transplantation succeeds significantly for most people in the long term. However, people who face great risks of refusing to transplant or experiencing serious complications need to study other solutions. As the operation may lead to serious risks. Therefore, it is imperative to consult a competent and reliable expert before making the decision to transplant the cornea, in order to find out the best procedure, that fits the patient’s lifestyle and gives him the best results.
