Cornea. 1985;4(1):51-7.
Two containers ("Iowa" and "Virginia") commonly used for transporting donor corneas, and various packing methods were evaluated for constancy of temperature maintenance. The larger Iowa container was found to be superior for extended storage. Packing methods that allowed the vials (containing McCarey-Kaufman medium) to be in direct contact with wet ice or with ice water resulted in the best cooling. Direct contact with supercooled ice may cause freezing of the medium. Separating the vials from the ice water slush by dry foam rubber or Styrofoam did not allow adequate cooling. Heat sealing the vials in a plastic bag containing minimal air permitted proper cooling and may reduce the risk of contamination from the ice water.
评估了两种常用于运输供体角膜的容器（“爱荷华州”和“弗吉尼亚州”）以及各种包装方法在维持温度稳定性方面的表现。发现较大的爱荷华州容器在延长储存时间方面表现更优。使小瓶（装有麦卡里 - 考夫曼培养基）直接接触湿冰或冰水的包装方法冷却效果最佳。直接接触过冷冰可能会导致培养基冻结。用干泡沫橡胶或聚苯乙烯泡沫塑料将小瓶与冰水混合物隔开无法实现充分冷却。将小瓶热封在空气极少的塑料袋中可实现适当冷却，并可能降低来自冰水的污染风险。
