Abstract

We compared the incidence of graft rejection and the rejection time after penetrating keratoplasty on the 72 keratoconus patients retrospectively between the range of 5.5 mm to 7.0 mm diameter in graft size(Group 1) and the range of 7.25 mm to 8.0 mm diameter(Group 2). The graft rejection was developed in 25 eyes(28.09%) among 89 penetrating keratoplasty patients with keratoconus. In group 1, there was graft rejection in 6 eyes(23.08%) among 26 eyes and in group 2, 19 eyes(30.16%) among 63 eyes. The rejection time of 21 eyes(84.00%) was within the first postoperative year. In group 1, graft rejections in 5 eyes(83.33%) were noted within the first postoperative year among 6 rejected eyes, and in group 2, rejections in 16 eyes(84.21%) among 19 rejected eyes. The statistical analysis showed no significant differences between the two groups in the incidence of graft rejection and rejection time(p>0.05).
