Three infants, one who was two weeks old, and two who were two months old, underwent lensectomy and vitrectomy in a total of four eyes for congenital cataracts by means of an automated suction cutter. Two patients with unilateral opacities underwent combined cataract extraction and epikeratophakia, and one with bilateral congenital cataracts underwent cataract extractions and was fit with extended wear contact lenses. In all cases, the surgery involved at least a 5-mm posterior capsulotomy with a shallow anterior vitrectomy, and was uneventful. Three of the four eyes developed new opacities that required surgical removal three to five months after the original surgery. Cytological evaluation of the specimen obtained from one patient showed this material to be lens epithelium. In all three cases, the material grew without the support of the posterior capsule; in one patient the material appeared to have seeded onto the iris. This previously unreported complication in infants with congenital cataracts who have undergone posterior capsulotomy and anterior vitrectomy emphasizes the need for frequent retinoscopies on such patients. The absence of the posterior capsule does not guarantee that these children will not develop secondary growth of lens epithelium which may obstruct the visual axis.
三名婴儿，一名两周大，两名两个月大，共四只眼睛因先天性白内障通过自动抽吸切割器接受了晶状体切除术和玻璃体切除术。两名单侧混浊患者接受了白内障摘除联合表层角膜镜片术，一名双侧先天性白内障患者接受了白内障摘除并佩戴了长戴型隐形眼镜。在所有病例中，手术至少包括一个5毫米的后囊切开术和浅前玻璃体切除术，且过程顺利。四只眼中有三只在初次手术后三到五个月出现了需要手术切除的新混浊物。对一名患者获取的标本进行细胞学评估显示该物质为晶状体上皮。在所有三例中，该物质在没有后囊支持的情况下生长；在一名患者中，该物质似乎已种植到虹膜上。这种在接受后囊切开术和前玻璃体切除术的先天性白内障婴儿中先前未报道的并发症强调了对此类患者进行频繁视网膜检影的必要性。后囊的缺失并不能保证这些儿童不会发生可能阻塞视轴的晶状体上皮继发性生长。
