背景：研究发现晶体上皮细胞的凋亡是白内障发生的共同细胞学基础。
BACKGROUND: it was reported that the apoptosis of lens epithelia was the common cytological basis of the genesis of cataract.
在超微结构上，晶体上皮细胞及晶体细胞未出现明显的病理改变。
No obvious pathological lesions occurred in ultrastructure of lens epithelia and lens cells.
其后囊下混浊发生的机制主要与残留晶体上皮细胞迁移、增殖和转分化有关。
