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。
Objective To observe the effect of neonatal corneal modified penetrating keratoplasty to correct high myopia after conventional surgery. Methods According to the geometrical calculation, the calculation formulas of the diameters of donor and recipient corneal radii were deduced, and the experimentally penetrating keratoplasty of 25 rabbits was performed using bridge flap implant. Postoperative corneal refractive power was measured. Results The average corneal refraction in experimental group (49 eyes) was 49.11 ± 4.72D at 6 months after operation and 60 days in control group (P <0.01). Conclusion The improved method can reduce neonatal donor corneal transplantation after high myopia, a clinical study.
