CORNEA TRANSPLANTATION
SPECIALISTS IN CORNEAL TRANSPLANT SURGERY
WHAT IS CORNEAL TRANSPLANTATION?
Corneal transplantation is a surgical procedure that involves the partial or total replacement of damaged corneal tissue by a healthy corneal tissue.
The new corneal tissue that is transplanted into the patient usually comes from a donor.
This is a common intervention, in which the most common is to use local anesthesia and whose duration is usually less than an hour.
In most corneal transplants, the results obtained after this operation are satisfactory.
WHEN IS IT NECESSARY TO CARRY OUT THIS TECHNIQUE?
The cornea is a transparent surface located in the anterior part of the eye and there are some eye diseases that alter transparency and corneal anatomy.
Keratoplasty or corneal transplantation is indicated when other less invasive solutions have failed.
The main pathologies that may require a corneal transplant are:
- Keratoconus
- Fuchs dystrophy
- Herpetic keratitis
- Corneal ulcers
- Corneal scars
- Corneal thinning
TYPES OF CORNEA TRANSPLANTS
There are two main types of cornea transplants:
- Penetrating corneal transplant or penetrating keratoplasty: in this case, the entire damaged cornea is removed and exchanged for the healthy cornea of the donor.
- Lamellar corneal transplant or lamellar keratoplasty: in this type of transplant, one or more of the 5 layers of the cornea is replaced:
- DALK
- DMEK
- DSAEK
REJECTION OF CORNEAL TRANSPLANT
Corneal transplantation is a safe procedure, but it is not without risks.
In some patients, the body’s immune system may mistakenly attack the donor cornea. This is known as rejection, and the risk is very low compared to other human organ transplants.
This rejection can be stopped with topical medical treatment and the patient’s symptoms are usually:
- Redness
- Pain
- Loss of vision
HOW LONG IS THE RECOVERY TIME AFTER A CORNEAL TRANSPLANTATION?
Depending on the technique used to perform the transplant, the recovery time may vary.
Most patients leave the operating room with an eye bandage that is removed the day after surgery.
Thereafter the patient must strictly follow the medical treatment prescribed by the ophthalmologist, usually consisting of:
- Topical drops
- Oral medication
