title: Late spontaneous in-the-bag intraocular lens and capsular tension ring dislocation in pseudoexfoliation syndrome.
abstract: Two patients with pseudoexfoliation syndrome (PEX) in whom late spontaneous in-the-bag intraocular lens (IOL) and capsular tension ring (CTR) dislocation occurred 3 and 6 years after cataract surgery are described. The patients received CTRs because of phacodonesis due to zonular laxity. The IOLs were centered postoperatively, and there was no postoperative ocular trauma. In both cases, removal of the IOL and CTR within the capsular bag was performed uneventfully by a scleral tunnel incision and an anterior chamber IOL was implanted. Capsular tension ring implantation in PEX-associated zonular weakening does not guarantee long-term zonular stability and capsular bag/IOL position in these patients after cataract surgery.
