We report a case in which the capsular bag with an intraocular lens (IOL) and a capsular tension ring (CTR) dislocated into the vitreous. The dislocated foldable posterior chamber IOL and CTR were removed with a pars plana vitrectomy and exchanged with a scleral-fixated IOL. No complications occurred intraoperatively or postoperatively. Although insertion of a CTR decreases the risk for IOL dislocation, spontaneous capsular bag dehiscence can occur.
