A simple, practical, and safe method for evaluating donor corneas prior to their use for grafting is based on the fact that trypan blue, a vital stain, is taken up only by dead or damaged endothelial cells, the normal cells remaining unstained. Individual units are available which allow one to prepare a sterile solution of the dye instantaneously for each cornea. No harmful effects have been observed either in extensive experimental tests or by clinical experience.
