Better Cornea Transplant - Ophtalmologists Develop Laser Procedure to Shorten Patients' Recovery HOW IT WORKS: Cornea transplants have traditionally only been performed in severe cases, since the majority of transplant recipients don't see improvements in their vision for at least six months, and even then strong glasses or contact lenses are needed because of remaining distortions. The cornea is slow to heal, and the transplant can remain vulnerable to injury for the rest of the patient's life. As many as 40,000 cornea transplants are performed each year in the United States. www.aip.org /dbis/stories/2006/15210.html   (490 words)

Organ transplant - Open Encyclopedia   (Site not responding. Last check: 2007-10-31) An organ transplant is the transplantation of an organ (or part of one) from one body to another, for the purpose of replacing the recipient's damaged or failing organ with a working one from the donor. That term is also used for a special form of liver transplant, in which the recipient suffers from familial amyloidotic polyneuropathy causing the liver to produce a (very slow) poison; their liver can be transplanted into an older patient who is likely to die from other causes before a problem arises.

Cornea transplant Summary In a corneal transplant, a disc of tissue is removed from the center of the eye and replaced by a corresponding disc from a donor eye. A cornea transplant, also known as a corneal graft or penetrating keratoplasty, is a surgical procedure where a damaged or diseased cornea is replaced by donated corneal tissue which has been removed from a recently deceased individual having no known diseases which might affect the viability of the donated tissue.

Cornea Treatment and Transplant Surgery by a Skilled Ophthalmologist in Florida - Ocala Eye In addition, the surgery is safer as the new cornea is inserted through a small incision rather than a complete opening of the front part of the eye reducing the chance of a devastating hemorrhage during the surgery or infection afterwards. The cornea is also left much thicker than the original due to the addition of tissue to the posterior aspect of your current cornea. Like full thickness corneal transplantation, eye drops are required for at least a year and more often for the rest of your life to prevent graft rejection, where the body recognizes the tissue as being foreign and reacts against it. www.ocalaeye.com /html/cornea.html   (2052 words)

Cornea Research Foundation - Cornea Conditions & Updates This occurs because evaporation of fluid from the cornea is decreased while the eyes are closed during sleep, and accumulation of fluid in the cornea during the night results in corneal swelling (edema). Corneal hydrops, or marked swelling of the cornea may occur when severe bulging of the cornea results in a tear in the deepest layer of the cornea (Descemet's membrane), allowing fluid from the inside of the eye to permeate the cornea. The rigid lens masks the underlying irregular cornea and functions as the new refractive surface of the eye, with the tear film filling in the space between the back of the contact lens and the front of the eye. www.cornea.org /research_cornea.html   (1741 words)

ScienceDaily: UCI Eye Doctors Invent Laser-assisted Cornea-transplant Surgery Cornea transplants are performed on the “front window” of the eye, using living tissue from donors to replace corneas in which swelling, scars, distortions and degenerations are causing blindness. While most transplants are successful in providing the patient with a clear cornea, the majority of cornea transplants take more than six months to provide good vision, and even then strong glasses or contact lenses are needed. In addition, stitches usually need to stay in place for years, because the cornea is slow to heal and, as a result, the transplant remains a weak spot, vulnerable to injury for the rest of the patient’s life. www.sciencedaily.com /releases/2005/05/050503153640.htm   (797 words)

New Cornea Transplant Method - DSAEK in Dallas at Cornea Associates of Texas The most likely option was for them to undergo full thickness corneal transplant – a complicated procedure that surgically replaces the entire damaged cornea with a donor cornea. Rather than removing the entire cornea, our transplant doctor in Texas makes a small incision in the side of the eye and replaces only the damaged portion at the back inner dome of the cornea with donor cells. The transplanted cells begin pumping fluid out of the cornea, thus creating a suction that causes them to adhere to the back of the host cornea. www.corneatexas.com /html/procedures_dsaek.html   (464 words)

Cornea Transplant Columbus, Ohio The cornea must remain transparent and of regular curvature to properly focus and transmit light as it enters the eye. The tension generated by the sutures within the cornea often cause distortion of the curvature of the graft, causing the refraction of the eye to shift unpredictably. If the cornea surface is regular, and the prescription of the other eye is not too different, it is sometimes possible to prescribe glasses during this early rehabilitation period but the prescription lenses may need to be periodically changed as the cornea heals. www.icanseeclearly.com /otherservices/cornea.htm   (1214 words)
