Eye bank Eye bank Eye banks recover, prepare and deliver donated eyes for cornea transplants and research. The first successful cornea transplant was performed in 1905 and the first eye bank was founded in 1944. Currently, in the United States, eye banks provide tissue for over 80,000 cornea transplants each year to treat conditions such as keratoconus and corneal scarring.
