BACKGROUND
Pupillary block rarely occurs after cataract extraction with posterior chamber intraocular lens implantation.
METHODS
A series of six patients (seven eyes) treated for pupillary block after posterior chamber intraocular lens implantation between 1990 and 2001 is described; in one eye, the attack occurred after phacoemulsification.
RESULTS
The interval between pupillary block development and the cataract surgery ranged from 1 day to 5 years. In all eyes, treatment consisted of neodymium-YAG laser peripheral iridotomy. In four eyes, the laser peripheral iridotomy relieved the block (one procedure in two; two to three procedures in two). One patient was also treated with YAG capsulotomy, and two patients needed additional surgical intervention.
CONCLUSION
Despite the rarity of the complication of pupillary block after posterior chamber intraocular lens implantation, physicians should be aware of the sometimes difficult course of recovery after treatment.
背景
后房型人工晶状体植入术后很少发生瞳孔阻滞。
方法
描述了1990年至2001年间接受后房型人工晶状体植入术后瞳孔阻滞治疗的一系列6例患者（7只眼）；其中1只眼的发作发生在超声乳化术后。
结果
瞳孔阻滞发生与白内障手术之间的间隔时间为1天至5年。所有眼均采用钕-YAG激光周边虹膜切开术治疗。4只眼中，激光周边虹膜切开术解除了阻滞（2只眼进行了1次手术；2只眼进行了2至3次手术）。1例患者还接受了YAG晶状体囊切开术，2例患者需要额外的手术干预。
结论
尽管后房型人工晶状体植入术后瞳孔阻滞并发症很少见，但医生应意识到治疗后有时恢复过程会很困难。
