Abstract

Abstract: : Purpose: To compare the outcome of penetrating keratoplasty performed by supervised cornea fellows and an experienced staff surgeon. Methods: Retrospective review of cases of penetrating keratoplasty performed over a 4 year period with corneal topography performed on a clear graft. Overall, 202 cases from 184 patients were included: 108 performed by an experienced staff surgeon and 94 cases by 9 cornea fellows. Charts were reviewed for topographic astigmatism, other topographic indices, refractive astigmatism and best–corrected visual acuity (BCVA), all recorded after removal of the 10–0 sutures while the 11–0 suture remained in place. Graft clarity was assessed at final follow up. Results: Mean postoperative topographic astigmatism was 4.60±2.7 diopters in the fellows group and 4.08±2.41 diopters in the staff group. Mean refractive astigmatism was 3.77± 1.97 diopters (fellows) and 3.49±1.93 diopters (staff). Mean SAI was 1.89±1.42 (fellows) and 1.61±1.08 (staff). Mean SRI was 1.43±0.72 (fellows) and 1.45±0.61(staff). Mean BCVA was 0.49 logMAR (20/61)±4.3 lines (fellows) and 0.47 logMAR (20/59)±3.9 lines (staff). In the fellows group, 85 (90%) cases remained clear over a mean follow up time of 32 months and in the staff group 100 (93%) grafts remained clear over a mean follow up time of 38 months. Simple and multiple regression analysis indicated no difference between the 2 groups in all outcome measures. Conclusions: Well supervised cornea fellows in training can achieve favourable penetrating keratoplasty results that are comparable to experienced staff surgeons.
