角膜位于眼球前部,容易患病和受外伤,角膜发病率之高超过眼的任何部位,对于这类疾病及其后遗症的治疗,有很多办法,其中有一部分可用板层角膜移植来治疗。可是材料来源是个问题,虽然近年来对同种异体角膜材料的保存方法有了很大进展,但仍然处于供不应求的状态。在角膜移植的初期,Chisholm(1988)就曾试用异种角膜移植,但未能成功。以后继续研究这一间题的,不乏其人。1953年和利用低温条件保存的动物角膜给2例盲人进行了移植,一例用的是猫眼,一例用的是鸡眼,近期虽然获得愈合,但最后均告混浊。(1957)进
Cornea in the front of the eye, prone to illness and trauma, the cornea incidence higher than any part of the eye, for the treatment of such diseases and their sequelae, there are many ways, some of which can be treated with lamellar keratoplasty. However, the source of the material is a problem. Although great progress has been made in the preservation of allogenic corneal materials in recent years, it is still in short supply. In the early stages of keratoplasty, Chisholm (1988) tried heterogenous keratoplasty but failed. After continuing to study this issue, there is no shortage of people. In two cases, two animals were transplanted in the animal cornea preserved in 1953 under hypothermic conditions. One case used a cat’s eye, and one case used a corns. In the near future, although healed, it ended in turbidity. (1957) into
