According to the Eye Bank Association of America (EBAA), eye banks can be defined as “a non-profit organization that obtains, medically evaluates and distributes eye tissue for transplant, research, and education” [1]. Ideally, an eye bank should function autonomously and not be part of a medical organization[2].

Eye banks feature a wide range of functions and specializations. Its operation may be based on: retrieval, storage, tissue evaluation, donor eligibility assessment, processing and distribution of transplant parts[1]. In relation to their specialization, they may work only with eyes, eyes and tissues or be part of an organ procurement organization[1]. In addition, several of these institutions work for the advancement of medicine, operating as research centers on issues related to eye storage and the restoration of sight.

Structurally, eye banks should have communication facilities, access to equipment such as a slit lamp and laminar flow hood, surgical instruments, sterilization facilities, a serology laboratory, preservation facilities and an adequate transport system. The division of functions basically takes place through two sectors: medical and administrative. The medical sector is coordinated by a medical director, who is usually an experienced corneal surgeon, and by professionals in the area who are responsible for supervising and carrying out technical procedures. The administrative sector, on the other hand, is coordinated by a team that is responsible for the institution's bureaucratic issues. Specifically, the medical ward handles tissue collection and its evaluation, preservation, and distribution. On the other hand, the administration is responsible for public awareness programs, contacting government and voluntary and health agencies, and fundraising[2].


The history of the emergence of eye banks is directly related to the development of corneal transplantation and tissue storage techniques. Corneal transplantation was conceptualized in the late 18th century by Guillaume Pellier de Quengsy[3], but it took more than 100 years until the first transplant in humans was performed by Eduard Zirm in 1905[4]. Despite advances, who made possible the idealization of the first eye banks was Vladimir Filatov who, in the 1930s, documented[5] and popularized the use of human cadaver corneas in well-done transplants. The eyes were enucleated within a maximum of a few hours after the donor's death, as the corneas were stored in ice boxes at 4°C and used in the interval between 20h-56h post-mortem[5]. This feat made it possible for the donor tissues to be stored and the first eye banks to emerge.

Eye banks began in the 1940s, when Paton inaugurated the first eye bank in the US - the Eye Bank for Sight Restoration, founded in New York in 1944[6]. The storage techniques, at the principle, were very rudimentary, being restricted to small glass bottles where the eyes were under a condition of humidity and controlled temperature[7]. In order to preserve the corneal endothelium, it was necessary for the transplant to take place within a maximum of 48 hours after the death of the donor[6]. Furthermore, quality control uses only the appearance of the cornea and the post-mortem time as a criterion, with no control over the transmission of possible infectious diseases[7].

In the early 1970s, McCarey and Kaufman[8] developed new techniques for preserving ocular tissues with the aim of maintaining the viability of the corneal endothelium. They used a standard culture medium with very low levels, supplemented with dehydrating agents and antibiotics. This technique allowed the conservation of the cornea for a period of 7 to 10 days[8]. Currently, new research and advances in storage techniques are allowing the donated tissue to be viable for a longer period. In organ culture, for example, the cornea can be preserved for up to about 5 weeks[9].
