晶状体是眼的透明屈光介质系统中的重要组成部分,一旦发生混浊影响眼的功能,就被称为白内障。晶状体的透明性是其最主要的光学特性,除了因为晶状体内部没有血管和神经以外,也与晶状体细胞间格外紧密规整的排布有关。晶状体表面的上皮细胞能够终生保持分裂增殖能力,成熟的细胞不 The lens is an important part of the transparent refractive media system of the eye. Once the opacification has an effect on the eye, it is called cataract. Transparency of the lens is its most important optical property, except for the absence of blood vessels and nerves inside the lens, as well as the closely packed arrangement of lens cells. Epithelial cells on the surface of the lens retain the ability to divide and proliferate for the rest of their life, and mature cells do not
