Also known as penetrating KERATOPLASTY and corneal transplant, corneal transplantation replaces Central corneal tissue from damaged cornea tissue healthy. People with damaged cornea tissue have blurred vision or vision glary. It is estimated that approximately 40000 people in the United States receive corneal transplants each year, of which 79% never suffer from rejection of the transplant. Although the rejection of the transplant occurs, can be successfully treated.
People with unhealthy cornea may be unsatisfactory work performance. It also depends on their functional vision, it still may not be corrected by glasses rimless seeds or rimless glasses. There are many situations that require a corneal transplant such as scarring, infection caused hereditary factors, Keratoconus, LASIK complications, chemical burns and excessive swelling of the cornea. Patients should also be a good plan, as a cornea transplant needs a recovery period of six months to a year. Before surgery, you should ask about prices and the potential benefits of vision.
Healthy cornea tissue are supplied by a local eye Bank, so that the recipient must wait for a donor's eye. Corneal donor tissue must be meticulously screened for the presence of diseases. A cornea transplant will take place on an external and anesthesia is often used to relax the muscles of the eyes of the recipient. During the two-hour operation, an area of the cornea, in the form of button will be removed and replaced by a nearly identical donor tissue. The small size of transplantation are the cause of lower risk of irregular shape of the cornea. The patient's eyes must be protected to avoid friction.
Transplant rejection can happen to a low incidence after less than a month. These first signs of transplant rejection include redness, light sensitivity, decreased vision and pain. Drugs are available to reverse the process of rejection. The worst case are according to corneal transplants.
Most people can return to work within several days after surgery, if necessary, but you should be banned from intense exercise and lifting during the first weeks. Patients should also protect the eyes of external objects, since their eyes are fragile in the recovery period. Your doctor will probably prescribe steroid eye drops to help the recovery of the patient. The entire recovery process may take longer than a year. For people with a low rate of healing, sutures can be removed after 17 months.
Given that the curve of the cornea transplant may not exactly match the curve of your existing cornea, corrective glasses are needed after a cornea transplant. And your vision will be stable after the healing process is finished, after which, the prescription of glasses can be determined with precision. Most doctors recommend PRSG for patients after a cornea transplant, from the surface of the cornea can be slightly affected.
