先天性白内障和发育性白内障是儿童失明的一个主要原因。这类白内障可以是胎内感染、发育异常、外伤或代谢紊乱的结果。外伤性白内障和发育性白内障(例如原始玻璃体持续增殖症)可以是单眼发病;胎内感染及代谢障碍所致的白內障,一般为双眼发病。用截囊术和抽吸术治疗这类白内障一向是行之有效的方法,即将晶体囊膜刺破随后将晶体内容物抽出,常常也施行晶体后囊膜刺开术。这类手术最主要的问题之一就是皮质残留,由于皮质残留,术后常发生细胞增生,而细胞增生的结果至少要遮挡部份视 Congenital cataracts and developmental cataracts are a major cause of blindness in children. Such cataracts can be the result of intra-fetal infections, dysplasia, trauma or metabolic disorders. Traumatic cataracts and developmental cataracts (such as persistent vitreous proliferative primary vitreous) can be monocular; cataracts due to intrauterine infection and metabolic disorders, usually with binocular onset. The use of capsulotomy and aspiration for the treatment of such cataracts has always been an effective method of puncturing the lens capsule and subsequently withdrawing the contents of the lens, often followed by posterior capsulotomy. One of the most important problems with such surgeries is the residual cortical area, which often leads to cell proliferation after surgery and the result of cell proliferation is at least partially obscured
