We present 12 cases of pupillary block associated with extracapsular cataract extraction and posterior chamber intraocular lenses. In one case, pupillary block occurred despite the presence of a surgical iridectomy. The other 11 patients did not have a surgical iridectomy performed. We recommend that a surgical iridectomy or laser iridotomy be performed in all patients who undergo extracapsular cataract extraction with the implantation of posterior chamber intraocular lenses. Ophthalmologists need to be vigilant in watching for the development of pupillary block in these patients, since pupillary block is not a benign event and serious visual loss or disability may occur.
我们报告了12例与囊外白内障摘除术及后房型人工晶状体相关的瞳孔阻滞病例。其中1例，尽管进行了手术性虹膜切除术，仍发生了瞳孔阻滞。另外11例患者未进行手术性虹膜切除术。我们建议，对于所有接受囊外白内障摘除术并植入后房型人工晶状体的患者，均应进行手术性虹膜切除术或激光虹膜切开术。眼科医生需要密切留意这些患者瞳孔阻滞的发生情况，因为瞳孔阻滞并非良性事件，可能会导致严重的视力丧失或残疾。
