Pupillary block glaucoma secondary to central port occlusion following insertion of a phakic implantable copolymer lens.

A 28-year-old woman had uneventful implantation of a phakic intraocular lens (pIOL) in her left eye (Visian ICL, EVO+ model, 13.2, -7.50 diopters) to correct myopia. Six days after the procedure, she presented with herniation of the iris. Surgical reduction was carried out successfully through the previous peripheral corneal paracentesis. On the following day, the patient reported ocular pain and blurry vision. Examination showed a shallow anterior chamber, moderate diffuse corneal edema, and ocular hypertension. The central port of the pIOL was blocked by iris pigment. The condition resolved completely after surgical iridectomy, and the postoperative course was uneventful. To our knowledge, this is the first reported case of pupillary block after implantation of a pIOL with a central hole. This uncommon complication should be taken into consideration when the iris is manipulated excessively after pIOL insertion.
