Replacement of a clouded cornea is the only means of restoring full vision. If the rest of the eye (including the retina and optic nerve) is normal , the cornea is replaceable through transplant surgeries. The success rate of the advances in research and surgical techniques. Corneal transplantation is one of the most successful organ transplant surgeries. The success of the procedure depends on the amount and type of damage the eye has sustained from disease or injury. The success rate can be as high as ninety-five percent. However, it is important to remember that vision can be restored only to the extent that the other parts of the eye are normal .
Why It's Done ?
A number of conditions can be treated with a cornea transplant, including:
- Thinning of the cornea
- Cornea scarring, caused by infection or injury
- Clouding of the cornea
- Swelling of the cornea
- Corneal ulcers, including those caused by infection
- Complications caused by previous eye surgery
Cornea transplant is a relatively safe procedure. Still, a cornea transplant does carry a small risk of serious complications, such as:
- Eye infection
- Increased risk of clouding of the eye's lens (cataracts)
- 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
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 another cornea transplant.
Make an appointment with your eye doctor if you notice any signs and symptoms of rejection, such as:
- Loss of vision
- Sensitivity to light
How You Prepare
Before cornea transplant surgery, you will undergo:
- A Thorough Eye Exam:Your eye doctor looks for conditions that may cause complications after surgery.
- Measurements Of Your Eye: Your eye doctor determines what size donor cornea you need.
- A Review Of All Medications And Supplements You're Taking: You may need to stop taking certain medications or supplements before or after your cornea transplant.
- Treatment For Other Eye Problems: Unrelated eye problems, such as infection or inflammation, may reduce your chances of successful cornea transplant, so your eye doctor will work to treat those problems before your surgery.
