Global Survey of Corneal Transplantation and Eye Banking

Corneal transplantation restores visual function when visual impairment caused by a corneal disease becomes too severe. It is considered the world's most frequent type of transplantation, but, to our knowledge, there are no exhaustive data allowing measurement of supply and demand, although such data are essential in defining local, national, and global strategies to fight corneal blindness.

To describe the worldwide situation of corneal transplantation supply and demand. DESIGN, SETTING, AND PARTICIPANTS: Data were collected between August 2012 and August 2013 from a systematic review of published literature in parallel with national and international reports on corneal transplantation and eye banking. In a second step, eye bank staff and/or corneal surgeons were interviewed on their local activities. Interviews were performed during international ophthalmology or eye-banking congresses or by telephone or email. Countries' national supply/demand status was classified using a 7-grade system. Data were collected from 148 countries. MAIN OUTCOMES AND MEASURES: Corneal transplantation and corneal procurements per capita in each country.
