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.

Keywords: intraocular lens implantation; pupillary block
