研究概览

简要总结

This multi-center clinical trial is designed to assess the association of diabetes in a cornea donor with transplant success and loss of endothelial cells 5 years following Descemet membrane endothelial keratoplasty (DMEK). Study eyes are assigned to receive either a cornea from a donor without diabetes or a cornea from a donor with diabetes in a masked fashion.

研究组 & 干预措施

Assigned cornea from a donor without diabetes

Active Comparator

Eyes assigned to this arm receive a cornea from a donor without diabetes and undergo Descemet membrane endothelial keratoplasty.

干预措施: Descemet membrane endothelial keratoplasty (Procedure)

Assigned cornea from a donor with diabetes

Active Comparator

Eyes assigned to this arm receive a cornea from a donor with diabetes for Descemet membrane endothelial keratoplasty.

干预措施: Descemet membrane endothelial keratoplasty (Procedure)

结局指标

主要结局

Change in central corneal endothelial cell density 5 years after Descemet membrane endothelial keratoplasty.

时间窗: Subjects are followed for 5 years after corneal transplantation.

Central corneal endothelial cell density will be assessed by specular microscopy at 3 and 5 years after Descemet membrane endothelial keratoplasty and the results will be compared with the baseline donor endothelial cell density assessed at the eye bank that provided the donor tissue.
