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.
报告一例因植入后房型有晶状体眼屈光性晶状体（PRL）诱发双侧色素播散综合征（PDS）的病例。
病例报告。
一名38岁女性双侧植入后房型有晶状体眼屈光性晶状体后，数月内出现单侧眼压升高，这归因于前房内色素播散。与色素播散综合征相符的表现包括双侧虹膜在与PRL前表面接触区域的透照缺损、PRL前表面的色素沉着、克-布二氏梭形色素沉着以及双侧小梁网致密色素沉着。患者目前眼压得到控制，尚未出现青光眼性损害。
该病例中色素播散综合征的发生表明，后房型有晶状体眼屈光性晶状体可与虹膜后表面接触，并在易感患者中诱发色素播散综合征。
