The aim of this article is to review the recent literature regarding corneal storage media since the last review that discussed this topic in substantial detail in this journal.During the last few years, despite the development of new corneal storage media and the addition of new additives to established corneal storage media, Optisol GS (Bausch & Lomb, Irvine, California, USA) has continued to remain the popular choice among storage media used in the United States, and traditional organ culture methods are still used in Europe. Recognizing that persistent epithelial defects after corneal transplantation can be a serious complication, however, attention has started to focus on not only preserving the endothelium, but also the epithelium. In addition, there has been more research towards antimicrobial prophylaxis.With recent evidence suggesting that longer storage times may allow better outcomes in high-risk grafts because of the depletion of donor T cells from the donor cornea into the storage media, storage media will need to be optimized for preserving the endothelium for longer periods of time. In addition, because the epithelium is typically unable to be sustained for longer than 1 week in storage media, research toward preserving the epithelium will also be essential.
