Delayed posterior dislocation of silicone plate-haptic lenses after neodymium : YAG capsulotomy

We report 4 cases of posterior dislocation of silicone plate-haptic intraoc ular lenses (IOLs) into the vitreous cavity occurring a mean of I 16 months after neodymium:YAG laser posterior capsulotomy. In each case, no peripher al capsule defect was observed at the time of laser capsulotomy or at subse quent follow-ups. One case was treated with sulcus implantation of a 3-piec e IOL, with the plate-haptic IOL left in the vitreous cavity. The other cas es were managed with vitrectomy (2 pars plana, 1 anterior) to remove the pl ate-haptic lens with subsequent sulcus placement of a 5-piece IOL. Patients should be informed that posterior dislocation is an infrequent but possibl e complication of these lenses and may occur months and even years after im plantation or laser capsulotomy.
