Claus Cursiefen, MD, and colleagues reviewed 19 studies involving nearly 24,500 corneal transplants (called "grafts"). The cornea is the eye's clear outer surface that provides much of the visual power. "The presence of corneal neovascularization before surgery makes it about 30 percent more likely that the transplant will fail, and more than doubles the risk of graft rejection," said Dr. Cursiefen. "We also found that the risks of failure and rejection rise with the extent of vascularization-the more extensive the corneal neovascularization, the higher the risks."
