A 49-year-old patient developed pupillary block glaucoma with an intraocular pressure (IOP) of 29 mm hg after implantation of a phakic intraocular lens (IOL) (NuVita, Bausch & Lomb) in the left eye. the anterior chamber deepened again, and the iop decreased to 16 mm hg after a neodymium: YAG iridotomy. Pupillary block glaucoma may occur after phakic IOL implantation without iridotomy, and we advocate that routine iridotomy be performed during phakic IOL surgeries.
