完整的角膜上皮对于穿透性角膜移植术后伤口的愈合和角膜的透明性是十分重要的。角膜移植手术时,是否要保留供体的角膜上皮有分歧。有的认为应去除,有的则以为要完整地保留,特别当受体的角膜上皮不健康时更应如此。作者的研究表明,即使保留了供体角膜上皮,也常在术后的头几天就死亡脱落。角膜的保存方法是影响供体角膜上皮的完整和活性的因素。人眼在湿房内贮藏6小时后角膜上皮即破损。兔眼摘除后立即行角膜移植术,供体角膜上皮在术后存活数月。研究表明要保全上
The intact corneal epithelium is very important for the healing of the wound after penetrating keratoplasty and the corneal transparency. Corneal transplantation surgery, whether to retain donor corneal epithelium disagreement. Some think it should be removed, while others think that they should be preserved intact, especially if the corneal epithelium of the recipient is unhealthy. Authors’ studies have shown that even if the donor corneal epithelium is preserved, it often falls off the first few days after surgery. Corneal preservation methods are factors that affect the integrity and activity of donor corneal epithelium. Corneal epithelium damaged 6 hours after storage in the wet room. Corneal transplantation was performed immediately after removal of the rabbit eye, and donor corneal epithelium survived for several months after surgery. Research shows that to be preserved
