 Purpose:To evaluate the validity of penetrating keratoplasty(PKP)using corneas donated from persons aged 80 years or over. Cases and Methods:We examined endothelial cell morphology of 96 corneas obtained from eyebanks for two years with a specular microsope before PKP. Thirty-three corneas were donated from persons aged 80 years or over and 63 corneas from those below 80 years of age. In another series,we evaluated the outcome of penetrating keratoplasty in 80 patients during 12 years from 1986 to 1998. Twenty-two corneas were donated from persons aged 80 years or over and 58 corneas from those below 80 years of age. Results:Density of corneal endothelial cells averaged 2,512 cells/mm2for donors aged 80 years or over and 2,720/mm2for those aged below 80 years. The difference was significant(p=0.04). There were no differences in the rate of graft transparency or averaged visual acuity 5 years after surgery between the two groups. Conclusion:Penetrating keratoplasty using corneas donated from octo-or nonagenarians is clinically useful.
