1·The material, method and results of the research on the injury threshold of rabbits' cornea caused by GW CO2 laser light are introduced in this paper.

本文介绍连续CO_2激光对青紫蓝灰兔角膜损伤阈值研究的材料、方法和结果。

2·Conclusion: the extensive epithelial injury can make cornea thinner, which results in the changes of corneal protrusion.

结论：兔角膜上皮广泛丧失可使角膜变薄，引起角膜曲率变大。
