Twenty-seven corneal transplantations with a mean duration of donor incubation of 14.3 days (group 1) and 36 transplantations with a mean duration of incubation of 29.8 days (group 2) were followed for 18 months. No significant difference was found in graft survival between the two groups (81 versus 80%). Almost all graft failures were found among pre-operatively defined high-risk cases, i.e. previously transplanted and/or vascularized recipient cornea. The profile of the corneal thickness curve was almost identical in the two groups, and normal values were reached in both. Visual acuity was 0.5 or better in 23% of the cases in group 1, and 35% in group 2. These figures were highly influenced by co-existing and complicating eye disease i.e. amblyopia, cataract, macular degeneration and glaucoma. The results show that 2 weeks and 4 weeks cultured cornea do not differ with respect to graft survival and thickness. The over all results indicate that long-term cultured donor material is suitable for corneal transplantation and fully comparable to material stored by other methods.
对27例供体角膜平均保存14.3天的角膜移植术（第1组）和36例供体角膜平均保存29.8天的角膜移植术（第2组）进行了为期18个月的随访。两组间植片存活率无显著差异（分别为81%和80%）。几乎所有的植片失败都发生在术前定义的高危病例中，即先前接受过移植和/或角膜血管化的受体。两组角膜厚度曲线几乎相同，且均达到正常值。第1组23%的病例视力为0.5或更好，第2组为35%。这些数据受并存和并发眼病（即弱视、白内障、黄斑变性和青光眼）的影响很大。结果表明，保存2周和4周的角膜在植片存活和厚度方面无差异。总体结果表明，长期保存的供体材料适用于角膜移植，且与其他保存方法的材料完全可比。
