Pupillary block glaucoma associated with a secondary piggyback intraocular lens.

A 53-year-old woman developed pupillary block glaucoma associated with iris capture of a piggyback intraocular lens (IOL) that was treated with laser peripheral iridotomy. The piggyback IOL was repositioned by dilating the iris pharmacologically and reclining the patient. The IOL maintained its proper position behind the iris with the use of low-concentration pilocarpine eyedrops. Pupillary block glaucoma can occur as a complication of secondary piggyback IOL implantation.
