摘　　要：目的观察新生儿供体角膜改良穿透角膜移植矫正常规手术后高度近视的效果。方法根据几何运算推导出供、受体角膜曲率半径不同时植片直径的计算公式，并采用大桥状瓣植床，行２５只家兔的实验性穿透角膜移植术。测量术后角膜屈光度。结果手术后半年时实验组（２５眼）平均角膜屈光度为４９．１１±４．７２Ｄ，对照组为６０Ｄ（Ｐ＜０．０１）。结论该改良方法可以减轻新生儿供体角膜移植术后的高度近视，有临床研究价值。bjectiveTo investigate the effect of modified penetrating keratoplasty on the prevention of conventional method’s severe postoperative myopia using newborn donor corneas.MethodsThe newborn donor corneas were used in 50 penetrating keratoplasty eyes of rabbits in this study.The improved method for calculating graft diameter and making recipient bed was introduced to the experimental group(25 eyes).The corneal refraction was meassured after 6 months.ResultsThe corneal refraction was 49.11±4.72 Diopter in the experimental group while 60 Diopter in the control group.ConclusionThis improved method for newborn donor corneal penetrating keratoplasty can partially prevent the severe postoperative myopia.
