How To Replace a Cornea Eyefographic


How To replace a Cornea Infographic; Corneal transplantation, also known as corneal grafting, is a surgical procedure where a damaged or diseased cornea is replaced by donated corneal tissue (the graft) in its entirety (penetrating keratoplasty) or in part (lamellar keratoplasty). The graft is taken from a recently deceased individual with no known diseases or other factors that may affect the viability of the donated tissue or the health of the recipient.

The cornea is the transparent front part of the eye that covers the iris, pupil and anterior chamber. The surgical procedure is performed by ophthalmologists, physicians who specialize in eyes, and is often done on an outpatient basis. Donors can be of any age, as is shown in the case of Janis Babson, who donated her eyes at age 10. The corneal transplantation is performed when medicines, keratoconus conservative surgery and cross-linking can not heal the cornea anymore. (Wikipedia)

  1. People who receive organ transplants must take anti-rejection drugs the rest of their life. Is this also true with a corneal transplant?

  2. Because the cornea is typically avascular – there are no blood vessels there – the immune system doesn’t have an easy way get to the transplant. If the immune system can’t ‘find’ the transplant it has a hard time rejecting it. Most corneal transplants don’t require long term therapy, although of course, there are always exceptions.
