[摘要]
眼球的屈光状态主要是由眼轴长度、角膜屈光力和晶状体屈光力决定的。而在这三个屈光要素中，我们对于角膜的变化争议最多。在不同的人群和不同的屈光状态下，角膜的变化不尽相同。这篇综述就是对现有关于角膜在正视和近视中变化的相关研究进行总结。

[Abstract]
Ocular refraction is mainly decided by the axial length, corneal power and lens power. Of these three refractive elements, only the change of cornea has aroused the most controversial discussion. Cornea has changed varying with refractive state and population characteristics. This paper is designed to review the information currently available concerning the change of the cornea in emmetropia and myopia.
