After-cataract can be defined as the retropupillary, non-vitreal opacification of the lens remnants occurring after extracapsular cataract extraction (ECCE) leading to disturbance of transparency and impairment of vision. The synonymous secondary cataract is confusing, since it is also and more frequently used as cataract secondary to ocular diseases (Duke-Elder 1969). The synonymous opacification of the posterior capsule is, in fact, a misnomer, since histological observations revealed that after-cataract is not proven to be the result of changes in the remaining posterior capsule itself, but is caused by proliferation of lenticular epithelial cells, fibroblasts, macrophages and even iris-derived pigment cells on the posterior capsule (Fig. 1).
后发性白内障可定义为囊外白内障摘除术（ECCE）后发生在瞳孔后的晶状体残余物的非玻璃体混浊，导致透明度障碍和视力损害。同义的继发性白内障容易造成混淆，因为它也更常用于指继发于眼部疾病的白内障（Duke-Elder，1969年）。事实上，后囊混浊这一同义词是用词不当，因为组织学观察表明，后发性白内障并非由剩余后囊本身的变化所致，而是由后囊上的晶状体上皮细胞、成纤维细胞、巨噬细胞甚至虹膜来源的色素细胞增殖引起的（图1）。
