Abstract Purpose: To analyze the indications, functional results, and rates of graft rejection and failure after bilateral penetrating keratoplasty (PK) in a major eye care hospital and research center in India. Methods: Retrospective review of the case records of 38 patients who underwent bilateral PK and had at least 6 months follow-up after cornealtransplantation in the second eye. Results: The mean age of the 38 patients (20 M, 18 F) was 35 ± 25 years (range, 0.5 to 79 years). Mean follow-up was 49 ± 23 months (range, 13.4 to 116.4 months) after surgery in the first eye and 31 ± 22 months (range, 6.6 to 103.6 months) after surgery in the second eye. The average time interval between surgery in the first and second eye was 18 ± 10 months (range, 0 to 38 months). The commonest indications for surgery were corneal dystrophies (50%),aphakic bullous keratopathy (21%), and keratoconus (11%). Postoperatively, secondary glaucoma occurred in 2 first and 3 second eyes. Best-corrected visual acuity at last follow-up was 〉 6/12 in 34% of first eyes and 50% of second eyes, and was 〉 6/60 in 26% and 18% of first and second eyes respectively. Allograft rejection occurred in 4 of the first eyes and 3 of the second eyes. The two-year graft survival rate in first eyes was 70% and in second eyes was 83%. Worse outcomes were noted in grafts performed for secondary endothelial failure. Earlier graft failure occurred in first eyes (54 ± 5 months) compared to second eyes (79 ± 10 months) (Logrank Test p = 0.2311).Conclusions: Bilateral penetrating keratoplasty has reasonable success in selected patients. Corneal transplantation in the second eye does not seem to increase the risk of graft rejection in either eye.
