Corneal transpant (pre-operative instructions)

The Cornea Transplant surgery is the most common and the best prognosis of all organ transplants in humans. It consists of removing the central part of the cornea of the patient and replace it with a donor cornea.

What is the cornea?

The optical system of the eye is like a camera and the lens above correspond to the cornea, it is like a watch glass.

Who may need a cornea?

Deciding which patient may warrant this surgery may take only the doctor for treatment advice. This surgery is performed on people who have:

1. Corneas with high curvature and tapered and it is not possible to improve their visual quality contact lenses. (Keratoconus)

2. Weakening after corneal cataract surgery. (Bullous keratopathy)

3. corneal scar after penetrating wound.

4. Scarring after infections by viruses, fungi or bacteria.

5. Problems with hereditary corneal opacity.

Who performs this surgery?

The doctor must perform an ophthalmologist specializing in cornea, trained to perform this surgery with a precise technique and has knowledge to guide his patient with a cornea problem.The corneal graft surgery is to replace the central part of its damaged by a healthy cornea. The cornea is obtained from the donor after the first 6 hours after deceased, who generously donated his eyes to you. I could restore vision, which is a final act of solidarity. The donor cornea is preserved properly in order to keep it alive for 3 to 10 days under refrigeration. He also has been studied in Eye Bank to ensure its viability and is free of contagious diseases.

What results can be expected?

Fortunately Corneal Collagen is a special fabric that has no vessels and this decreases by 90% the risk of transplant rejection. If given early treatment can stop an event with minimal rejection of corneal injury.

Where one donor cornea is obtained?

Corneal transplantation is a surgery that depends on the donation of corneas to the Eye Bank. Corneas are obtained from recently deceased donors. The tissue is studied strictly and rigorously by specialists in the Eye Bank staff and choose those with the best condition to be successfully transplanted.

What is an Eye Bank?

It is a non-profit institution composed of technical and medical staff prepared to carry out the process of obtaining and distribution of ocular tissues. 

 

CORNEAL TRANSPLANT: PRE-OPERATIVE RECOMMENDATIONS
