穿透性角膜移植手术的成功,材料的选择是一个重要问题。以往,一般认为5～60岁年龄的材料最为理想。欧美一些国家不主张用5岁以下婴幼儿材料,10个月以下的婴儿材料更不予以考虑;一些全身病,如小儿败血症等的材料也一般不用。这样,给穿透角膜材料之来源带来了一定的局限性。为了扩大供体材料的来源,我们自1981年以来曾利用2个月 The success of penetrating keratoplasty, the choice of materials is an important issue. In the past, generally considered 5 to 60 years of age the most ideal material. Some countries in Europe and the United States do not advocate the use of infants under 5 years of age, and infants under 10 months do not even consider them. Some systemic diseases such as pediatric sepsis are generally not used. Thus, to penetrate the source of corneal material has brought some limitations. In order to expand the source of donor materials, we have spent 2 months since 1981
