在猴-猴表层板层角膜移植术成功的基础上,进行了三例人-猴异种表层角膜镜片术。术眼均获透明愈合。观察期分別为1个月、3个月和2年。对3例表层角膜镜片术的术眼角膜进行了组织学检查,发现上皮厚度及基质角膜细胞正常,进行异种表层角膜镜片术必须根据以下三个因素:供受体组织结构和屈光参数相近;供体角膜要有前弹力膜和一定的厚度。另外,对手术方法也进行了某些改进。 On the basis of the success of monkey-monkey surface lamellar keratoplasty, three human-monkey heteroscleral keratomileusis were performed. Eye surgery were transparent healing. The observation period was 1 month, 3 months and 2 years respectively. Histopathological examination of the cornea of ​​3 cases of surface corneal ophthalmoscopy showed that epithelial thickness and stromal corneal cells were normal, and heterostructural surface corneal ophthalmoscopy must be based on the following three factors: the structure of the donor’s receptor and the refractive parameters were similar; Donor cornea to have a stretch film and a certain thickness. In addition, some improvements have been made to the surgical procedure.
