Neodymium-YAG laser posterior capsulotomy for the treatment of aphakic and pseudophakic pupillary block.

We examined five patients who developed pupillary block after extracapsular cataract extraction. One of the patients also had a posterior chamber intraocular lens implanted at the time of cataract operation. In all five patients, pupillary block was promptly relieved by Nd:YAG laser posterior capsulotomy.
