We describe 2 cases of pigment dispersion syndrome (PDS) after uneventful phacoemulsification and implantation of a posterior chamber single-piece intraocular lens (IOL) with a sharp-edge design. In both cases, several days after IOL implantation, marked pigment dispersion was seen on the iris and in the trabecular meshwork, associated with an elevation in intraocular pressure (IOP). Thorough examination showed that the implanted IOL was in the ciliary sulcus. After surgical repositioning of both IOLs in the capsular bag, the pigment dispersion regressed and the IOP returned to normal limits. The 2 cases suggest that particularly in PDS patients, an IOL with an anterior sharp-edge design should be implanted in the capsular bag. Implantation in the ciliary sulcus should be avoided.
我们描述了2例在顺利进行白内障超声乳化吸除术并植入后房型单片式人工晶状体（IOL）（其设计为锐缘）后发生色素播散综合征（PDS）的病例。在这两例病例中，人工晶状体植入几天后，在虹膜和小梁网处可见明显的色素播散，并伴有眼压（IOP）升高。全面检查显示植入的人工晶状体位于睫状沟内。在将两个人工晶状体手术重新定位到囊袋内后，色素播散消退，眼压恢复到正常范围。这两例病例表明，特别是对于PDS患者，应将具有前部锐缘设计的人工晶状体植入囊袋内，应避免植入睫状沟内。
