观察联合自 -异体穿透性角膜移植术后植片排斥反应的发生率和疗效。方法 :对 2 5例角膜病灶靠近边缘的患者 ,采用周边部新月形自体植片及中央部异体植片作穿透性移植术。另以植床靠边的旁中央穿透性移植术 2 8例为对照组 ,比较其术后排斥反应的发生率和角膜散光。结果 :两组植片的上皮排斥反应发生率分别为 8.0 %和 32 .1% ,实质层和内皮排斥反应为 2 8.0 %及 6 4.3% ,角膜散光为 3.82 D和6 .82 D。结论 :联合自 -异体穿透性角膜移植术可降低术后植片排斥反应发生率及减少术后角膜散光
To observe the incidence and efficacy of graft rejection after combined with allogeneic penetrating keratoplasty. Methods: Twenty-five patients with corneal lesions near the edge were treated with transplanting of crescent-shaped peri-implant and central allograft. In addition, 28 cases of transplanted central paracentesis were treated as control group, and the incidence of postoperative rejection and corneal astigmatism were compared. RESULTS: The rates of epithelial rejection in the two groups were 8.0% and 32.1%, respectively. The parenchymal and endothelium rejection were 28.0% and 62.3%, respectively. Corneal astigmatism was 3.82 D and 6.82 D. CONCLUSIONS: Combined with autologous allogeneic penetrating keratoplasty can reduce the incidence of postoperative graft rejection and reduce postoperative corneal astigmatism
