From 1984 to 1986, we performed cataract surgery through a 1.5 mm anterior capsule hole in 77 eyes. The hole was enlarged to 6.0 mm by a slit incision, and an intraocular lens was implanted into an almost completely intact capsular bag. Twelve (16%) eyes developed severe postoperative anterior capsule opacification. The opacified central anterior capsule, approximately 5 mm in diameter, was detached by can-opener anterior capsulotomy using a neodymium:YAG laser and fell into the inferior anterior chamber. Inferior corneal endothelial cell loss occurred in nine of the 12 eyes within 20 months after detachment; in six of the nine, inferior corneal endothelial cell density decreased 50% more than central cornea cell density. This method will be unsuitable for treating the extensive anterior capsule opacification that will occur when endocapsular cataract surgery that retains most of the lens capsule is widely performed in the future.
1984年至1986年期间，我们对77只眼睛通过1.5毫米的前囊切口进行白内障手术。通过裂隙切口将该切口扩大至6.0毫米，然后将人工晶状体植入几乎完全完整的囊袋内。12只（16%）眼睛出现了严重的术后前囊混浊。使用钕:钇铝石榴石激光通过开罐式前囊切开术将直径约5毫米的混浊中央前囊分离，其落入前房下方。在分离后的20个月内，12只眼中有9只出现下方角膜内皮细胞丢失；在这9只眼中，有6只下方角膜内皮细胞密度比中央角膜细胞密度降低了50%以上。当未来广泛开展保留晶状体囊的囊内白内障手术时，这种方法将不适用于治疗所出现的广泛前囊混浊。
