The eye is one of the most important organs of human being. It plays a fundamental role in life. It enables organisms to see. This is among the common senses any normal person is expected to have. Loss of sight is a major disability and may affect both eyes. It can arise from several causes which may affect any structure in this delicate organ. Some can be corrected while others are permanent. One of surgical operations that may assist in restoration of sight is cornea transplants.
The procedure is carried out in most parts of the world and is usually successful. It can only be done when the cause of blindness is due to corneal structure damage. This involves replacement of damaged parts with a suitable healthy corneal tissue from a donor. This structure is concerned with focusing light into the lens.
There are a number of etiological factors which are associated with this kind of operation. It is indicated to a patient when investigations show that it is scarred following herpes virus infection. Some genetical disorders of this part of eye, like dystrophy. Also when the structure fails to perform its functions after cataract operation it is recommended. If there is a swelling which is painful and cannot be controlled by lenses or any other medication procedure is the only solution.
Doctors who are specialized in dealing with eye are the professionals who can do the procedure successfully. This is one of the operations group under outpatient procedures. Keratoplasty is its medically approved name. The graft from the donor has to be compatible with that of patient in these cases. Some patients visit their doctors for it as a cosmetic value to them.
In order to do this surgery, the consent must be sought for legal matters. It has to be explained to the patient in simple terms. The doctor explains both the benefits and risks that may arise due to such mode of treatment. As a rule of the thumb for any operation, the basic tests must be performed and results interpreted.
The merits that come post operatively include the following. Restoration of sight is one long term effect that the patient values most. Others like pain control, improvement of appearance are other positive consequences. If these are expected, then this operation must be carried out by experts in this field.
On the other hand, there are complications which may emerge from such surgical operations. The graft may be rejected by the host leading to failure. This arises when the recipient react to the graft. It manifests by itchy rashes on the skin. Infections may be acquired due to delayed healing or poor hygienic conditions during the procedure. The invasions by microbes can be avoided by the use of prophylactic antibiotics.
The outcome of cornea transplants has been found to be good if it is done following standard procedures. This prognosis may be affected if the graft is obtained from unhealthy donor. Some conditions of patients influence restoration of vision. A good example known here is diabetic retinopathy. In case the graft is rejected the operation can still be repeated.
