Pigmentary dispersion syndrome induced by a posterior chamber phakic refractive lens.

Abstract

To report a case of bilateral pigmentary dispersion syndrome (PDS) induced by the implantation of posterior chamber phakic refractive lenses (PRLs). Case report. Following bilateral implantation of posterior chamber phakic refractive lenses in 38-year-old woman, unilateral elevated intraocular pressure (IOP) developed within months that was attributable to pigment dispersion within the anterior chamber. Findings consistent with PDS included bilateral transillumination defects of the iris in areas contacting the anterior surface of the PRLs, pigment deposits on the anterior surface of the PRLs, Krukenberg spindles, and bilateral dense pigmentation of the trabecular meshwork. The patient's IOP is presently under control and she has not developed glaucomatous damage. The development of PDS in this case demonstrates that posterior chamber phakic refractive lenses can make contact with the posterior iris and induce pigment dispersion syndrome in susceptible patients.
