Purpose: To report the influence of donor age on visual outcomes after corneal transplant. Materials and methods: Data was obtained by reviewing patient medical records for a series of 141 corneal transplants carried out at the Saint Louis University Eye Institute from 1996 to 1999. Results: Patients ranged from 12 to 89 years of age. Indications for corneal transplant were as follows: 51 (36%) due to pseudophakic/aphakic bullous keratopathy; 29 (20.5%)- previous transplant failure; 23 (16%)- corneal dystrophies; 21 (15%) - corneal scar; 9 (6%) - keratoconus; 5 (3.5%) - infectious keratitis; 2 (1.5%) - ruptured globe; 1 (0.5%) - staphyloma. Nine patients were excluded from the study because of loss to follow-up. For the purpose of analysis recipients were stratified to groups based upon age of the donor: group 1 (N=41) received tissue from donors 40 years of age or younger, group 2 (N=91) donors older than 40. Outcomes were determined by best-corrected visual acuities and were converted to logMAR values for statistical analysis. An odds ratio of 0.93 (confidence interval 0.41 – 2.11) indicated that there was no statistical difference between groups. Conclusion: In our study, the age of donor tissue did not influence visual outcomes of penetrating keratoplasty. Sample size limitations may have contributed to our inability to detect a difference between groups.
