Title	Refractive Results of Corneal Grafts
Abstract Nr.	2080

Purpose	To report the refractive results following corneal grafts on 65 eyes.
Methods	Sixty five eyes that underwent a corneal graft were analysed retrospectively. Mean age was 54.25 +/- 2.33 years while mean graft donor age was 63.86 +/- 1.22 years. Their refractive parameters were measured pre and post operatively over a mean period of two years (minimum 2 months to maximum 4 years). All grafts come from a certified Belgian eye tissue bank. Receptor corneal bed diameter had a mean size of 7.99 +/- 0.04 mm. Graft trephining was realized with the endothelial side up and its diameter was oversized by 0.25 to 0.50 mm relative to the trephined receptor cornea. Sutures were simple or combined (17 and 83% respectively).
Results	Postoperative visual acuities show a significant upwards trend and mean postop BCVA at all stages significantly exceeds preoperative BCVA. Preoperative spherical equivalent was -4.9 +/- 2.9D while 12 and 24 month spherical equivalent were -1.06 +/- 0.3D and -2.76 +/- 1.13D respectively. Preoperative astigmatism was 5.48 +/- 0.79D while 6 month, 12 month and 24 month postoperative astigmatism were at 3.15 +/- 0.83, 2.91 +/- 1.03D and 2.76 +/- 1.13D respectively, showing therefore a decrease in total absolute astigmatism from before to after keratoplasty. Endothelial failure due to late graft rejection was seen in 13 eyes (21.3%) with loss of BCVA.
Conclusion	Corneal grafts may offer a significant visual improvement with positive changes when comparing the pre and post operative refractive parameters, but graft rejection rate has still a limitating impact on visual rehabilitation.
