    Summary

    Donor age did not significantly impact corneal graft survival or endothelial cell density in this study. Shorter death to preservation times were associated with fewer epithelial abnormalities in donor corneas.

    Area of Science:

    • Ophthalmology
    • Transplantation immunology

    Background:

    • The Cornea Donor Study (CDS) investigates factors influencing long-term corneal graft survival.
    • Donor characteristics, including age, endothelial cell density, and preservation time, are critical for successful transplantation.

    Purpose of the Study:

    • To determine the relationship between donor age and long-term corneal graft survival.
    • To evaluate donor population characteristics in relation to donor age, endothelial cell density, and death to preservation interval.

    Main Methods:

    • A prospective, double-masked, controlled trial involving 1101 donor corneas.
    • Donor corneas were assigned irrespective of donor age.

    Main Results:

    • Donor age showed minimal association with slit-lamp characteristics, except for corneal arcus.

  • Endothelial cell density remained relatively stable with donor age beyond 60.
  • Reduced death to preservation time correlated with fewer epithelial abnormalities, stromal edema, and Descemet folds.

    • Conclusions:

    • Donor age does not appear to significantly affect corneal graft characteristics or endothelial cell density.
    • Shorter death to preservation intervals are linked to improved corneal tissue quality, indicated by fewer epithelial abnormalities.
