Corneal transplantation

an introduction:

Corneal transplantation is the most successful tissue transplantation process that relies on replacing the cornea with a human cornea taken from a newly deceased person after it has undergone rigorous tests to ensure it is free of infectious diseases, and is set with appropriate standards to preserve it.

 

What are the reasons for cornea transplant?

  • Keratitis (bacterial, fungal or viral) keratitis leads to ulceration and ulceration of the cornea, then its opacity and loss of transparency.
  • Keratoconus.
  • Corneal injury, either with acute pain or with a chemical incendiary, especially if it is alkaline.
  • Corneal congestion occurs after cataract surgery.
  • Hereditary corneal failure.
  • The body rejected a previously implanted cornea.

 

How is the cornea transplanted?

After removing the damaged cornea, the cornea to be transplanted to the surface of the eye is fixed with fine surgical sutures that are left in place for a period determined by the doctor.

 

What are the complications that can occur?

  • The body’s rejection of the cornea is rare, with a rate not exceeding 10%. The signs for this are:
  • Eye redness.
  • Vision deterioration.
  • Eye sensitivity to light.
  • Feeling severe eye pain.

With correct and rapid treatment, the body’s rejection of the cornea can be stopped in most cases. Therefore, you should refer to the doctor as soon as possible, even if this occurs after years of the operation.

Very rare complications also occur, such as:

  • Increased intraocular pressure
  • High astigmatism (astigmatism) may occur after the operation, which may delay the return of eyesight.

All these complications can be treated according to the patient’s condition.

It should be noted here that it is important that the patient is keen to follow up with the doctor and use the prescribed drops accurately and expedite the examination of the eye in the event of complications, God bless.
