Study will help prevent infections following corneal transplant
Over 40,000 cornea transplantations are performed annually in the U.S., and well over 90%
successfully restore vision. Because there is no synthetic material that will serve as a substitute for
human corneal tissue, patients with eye injuries or diseases of the cornea depend upon donations
to eye banks for healthy corneal tissue. The handling and storage of human tissue is extremely
important to eye banks.
The Midwest Eye Bank and Transplantation Center has funded a study by Dr. Elmer Tu, assistant
professor and director of the Cornea Service, that will determine the effectiveness of adding
antibiotic vancomycin to the current corneal tissue storage medium in stopping the growth of
bacteria resistant to other antibiotics. Vancomycin may reduce contamination by the resistant
organisms, which should lead to a decrease in post-transplant infections, primarily endophthalmitis.
While rare, this infection can lead to blindness.
