What is the corneal transplant?
corneal transplantation is a surgery used to replace the patient's cornea by one of the deceased donor. Transplantation also known as keratoplasty is commonly used to restore vision and pain and discomfort when the cornea is patient or damaged. Performed as an outpatient procedure, there are potential complications and risks associated with corneal transplantation, which should be discussed with a healthcare professional before the operation.
successfully performed for the first time in 1905, corneal transplantation is used as a treatment for different conditions that lead to corneal deterioration. Conditions such as corneal dilution or cloudy, complications resulting from previous eye operations or corneal ulcers can be repaired by corneal transplant. The prognosis after the procedure depends on the success of surgery, aftercare and overall eye health.
Before the corneal corneal transplant is performed, the patient's condition must be evaluated. A comprehensive eye test takes place to makeIt ensured that no conditions could be present that could lead to complications after surgery, and the eye is measured to determine the size of the desired gift cornea. In cases where a basic condition such as inflammation or infection is discovered, it must be treated before continuing surgery.
Before the procedure, the patient has a slight sedative to support relaxation and the local anesthetic is given for a numb eye. During surgery, the patient is conscious and should not feel any pain. The whole thickness of the sick cornea is precisely cut and replaced by the cornea of the donor, which is stitched to the site of a fine fiber and later removed during the postoperative subsequent visit.
Not all corneal transplants are carried out to connect the entire cornea. In some cases, only partial transplantation, known as lamellar transplantation, is required. Only the interior is cut during deep lamellar transplantationThe corneal layer and the donor graft replaces the removed part of the cornea. When the highest corneal layer needs to be replaced, surface lamellar transplantation is performed.
After corneal transplantation, medicinal eye drops and oral medicines are given to the patient to prevent infection, pain and swelling. Protective metal eye patch and gauze are also used to protect the eye from injury and minimize swelling. Once the cornea has recovered, it may take several months for the patient to experience vision.
The corneal refusal occurs when the immune system attacks the donor's cornea. In case of rejection, further corneal transplantation is required. Symptoms of refusal include loss of vision, light and pain sensitivity.
The overall risk of developing corneal transplant complications is minimal. Complications may include inflammation and irritation associated with the stitches and rejection of the cornea of the donor. Risks associated with corneal transplantation include eye infections, glaucoma and cataracts.
