Corneal transplant

What is a corneal transplant ?

A corneal transplant, also known as a corneal graft or keratoplasty, is a surgical procedure in which a damaged or diseased cornea is replaced with a healthy cornea from a donor. The cornea acts as a transparent, curved layer that envelops the front part of the eye, aiding in the precise focusing of incoming light.

A corneal transplant may be necessary to restore vision in cases where the cornea has become scarred, distorted, or swollen due to a variety of conditions, including:

Keratoconus, a condition in which the cornea becomes thin and cone-shaped ;
Fuchs’ dystrophy is a degenerative condition that affects the corneal endothelium ;
Corneal scarring from injury or infection ;
Corneal ulceration or perforation ;
Corneal edema (swelling) due to a failure of the cornea’s pumping mechanism ;

The cornea for transplantation is obtained from a deceased donor whose eyes are healthy and who has consented to donate their corneas. The transplant is typically performed under local anesthesia, and the damaged portion of the recipient’s cornea is removed and replaced with the donor cornea, which is then secured in place with sutures. The procedure is generally safe and effective, although there is a risk of complications, including rejection of the donor cornea.

Corneal transplant price

The cost of a corneal transplant can vary depending on several factors, including the geographic location, the type of procedure, and the specific healthcare provider or hospital performing the surgery.

In Tunisia, the cost of a corneal transplant typically ranges from $3,000 to $5,000. This cost includes the surgical procedure itself, as well as pre-operative and post-operative care.

It is worth noting that many health insurance plans cover the cost of corneal transplantation, although the exact coverage and out-of-pocket expenses may vary depending on the plan. It is important to check with your insurance provider to understand what is covered and what your financial responsibility will be.

Additionally, there are some organizations that provide financial assistance to help cover the cost of a corneal transplant for those who are uninsured or underinsured. These organizations include the Eye Bank Association of America, the National Keratoconus Foundation, and the Cornea Research Foundation of America, among others.

How the corneal transplant is performed ?

A corneal transplant, also known as a corneal graft or keratoplasty, is a surgical procedure in which a damaged or diseased cornea is replaced with a healthy cornea from a donor.

Here are the steps typically involved in the procedure :

Anesthesia : The surgery is typically performed under local anesthesia, which numbs the eye and surrounding area while allowing the patient to remain awake during the procedure ;
Removal of the damaged cornea : The surgeon will make a small incision in the cornea and remove the damaged portion of the cornea. The donor cornea is prepared by an eye bank and is typically larger than the recipient’s cornea to ensure a good fit ;
Placement of the donor corne : The donor cornea is then placed onto the recipient’s eye and secured in place with sutures or a temporary stitchless adhesive. The sutures or adhesive will hold the cornea in place as it heals ;
Post-operative care : After the surgery, the patient will be given eye drops to prevent infection and to help with the healing process. Follow-up appointments will be scheduled to monitor the healing of the cornea and to remove the sutures once the cornea has fully healed ;

The exact technique used for a corneal transplant may vary depending on the specific case and the surgeon’s preference. In some cases, additional procedures may be performed at the same time as the corneal transplant, such as cataract surgery or glaucoma surgery. The overall success rate of corneal transplants is high, but there is a risk of complications, including rejection of the donor cornea. It is important to follow all post-operative instructions from the surgeon to minimize these risks and ensure the best possible outcome.

Precautions to take after a corneal transplant

After a corneal transplant, it is important to take certain precautions to ensure proper healing and prevent complications Ensure to maintain these precautions for your safety:

Avoid rubbing your eyes : Rubbing your eyes can increase the risk of infection or dislodging the new cornea. If you need to touch your eyes, be sure to wash your hands thoroughly first ;
Use eye drops as directed : Your doctor will prescribe eye drops to help prevent infection and inflammation and promote healing. Use them exactly as directed and do not skip any doses ;
Wear an eye patch or shield : Your doctor may recommend wearing an eye patch or shield to protect your eye and prevent accidental rubbing or bumping ;
Avoid strenuous activities : You should avoid any activities that may increase eye pressure or strain, such as heavy lifting, bending over, or exercising. Your doctor will give you specific instructions on when you can resume normal activities ;
Attend follow-up appointments : It is important to attend all follow-up appointments with your doctor to monitor your healing and detect any complications early ;
Use sunglasses : Wearing sunglasses can help protect your eyes from bright light and UV radiation, which can slow the healing process ;
Take care of your general health : Eating a healthy diet, getting enough rest, and avoiding smoking can all help promote healing after surgery ;

Following these precautions can help ensure a successful outcome after a corneal transplant. It is important to discuss any concerns or questions with your doctor, as they can provide personalized advice based on your individual case.
