Pupillary Block Glaucoma After Implantation of Iris-Fixated Phakic Intraocular Lens.

To report a case of pupillary block glaucoma after implantation of iris-fixated phakic intraocular lens (IF pIOL). A 43-year-old man was referred for pupillary block one day after implantation of IF pIOL. Slit-lamp examination revealed extremely shallow anterior chamber, closure of peripheral laser iridotomy and contact of iris on the peripheral of the optics of IF pIOL. The intraocular pressure (IOP) was 62 mm Hg. The iris moved forward in contact with the IF pIOL and the lens remained in the physiologic position, which made the distance between the lens and the iris wide. He underwent an uneventful peripheral surgical iridectomy and the IOP decreased to 6 mm Hg. Acute pupillary block glaucoma can occur after IF pIOL implantation due to the occlusion of aqueous flow between the IF pIOL and the iris if the peripheral iridotomy closes.
