—Reading the excellent study about donor age and success in penetrating keratoplasty by Drs. Forster and Fine in the January 1971 issue of the Archives (85:42-47), I was very glad to find that "No statistically significant difference in results due to donor age could be demonstrated." This statement confirmed the conclusions drawn by me 52 and 49 years ago from studies on corneal transplantations performed by my teacher Elschnig in the years 1908 to 1921 (Graefes Arch Ophthal99:339, 1919, and 107:439, 1922). I shall quote from our more modest statistics the following data which appear in the Table.That time, we concluded that the age of the donor does not influence the result of keratoplasty.
