Fixed, dilated pupil after phakic intraocular lens implantation

J Cataract Refract Surg. 2006 Jan;32(1):174-6. doi: 10.1016/j.jcrs.2005.11.016.


A 26-year-old man with degenerative high myopia had bilateral anterior chamber phakic intraocular lens (IOL) implantation under general anesthesia. The preoperative slitlamp examination was normal. No mydriatic drops were used before, during, or after the procedure. Postoperatively, the intraocular pressure (IOP) in the right globe increased to 60 mm Hg. After the IOP was controlled, the pupil became fixed and dilated. Iris fluorescein angiography was obtained and delayed filling of the iris capillary plexus with large areas of no perfusion was observed in the right eye. Based on these findings, a diagnosis of Urrets-Zavalia syndrome was made. To our knowledge, this is the first report of Urrets-Zavalia syndrome after phakic IOL implantation.
