Donor Tissue Research Paper

Donor tissue should be removed within 12-24 hours of death. The optimal death-to-preservation time is 12-18 hours. There is an attempt to age-match donors and recipients. Corneas from infants (3 years and under) are used only very occasionally, even for pediatric transplants, as they are associated with surgical, refractive and rejection problems. Most surgeons do not use corneas from donors younger than 24 months, as these corneas are extremely flaccid and can result in high corneal astigmatism and myopia postoperatively. Most eye banks establish a lower donor age limit of 24 months and an upper age limit of 70 years, as older corneas tend to have lower endothelial cell counts
Most corneas are stored in coordinating eye banks prior to transplantation,
