角膜移植术后,部分病人发生排斥反应,导致植片混浊。现将我院防治术后排斥反应的方法介绍如下。例1 何××男因左眼角膜斑翳入院。术前左眼视力0.02。行穿透角膜移植术,材料为新鲜角膜。植片直径6.6mm,植床直径6.5mm。用10—O尼龙线连续缝合,线头埋藏于角膜创口内。术后第11天发现有大量新生血管生长,用锶~90照射两次,每次三个照射点,每点照射1分钟,两次照射间隔12天。照射后新生血管闭锁,植片透明。术后追踪观察3年,未发生排斥反应。矫正视力0.5。例2 岳××男性因右眼圆锥角膜入院。术
After corneal transplantation, rejection occurred in some patients, leading to opacification of the grafts. Now hospital prevention and treatment of rejection after the method described below. He × × male patients with left corneal plaque admission. Preoperative left eye visual acuity 0.02. Line penetrating keratoplasty, the material is fresh cornea. Implant diameter 6.6mm, bed diameter 6.5mm. Continuous suture with 10-O nylon thread, thread buried in the corneal wound. On the 11th day after operation, a large number of neovascularization were found. The stroma was irradiated twice with strontium-90. Each time three irradiation spots were irradiated for 1 minute at each point, and the interval between two irradiation was 12 days. Neovascularization after irradiation atresia, transparent graft. After 3-year follow-up observation, no rejection occurred. Corrected vision 0.5. Example 2 Yue × × male due to right eye keratoconus admission. Surgery
