title: Late spontaneous haptic disinsertion from a three-piece intraocular lens.
abstract: OBJECTIVE
  To report two cases of spontaneous, late-onset haptic disinsertion from a three-piece posterior chamber intraocular lens (IOL).
  
  
  METHODS
  Interventional case reports.
  
  
  METHODS
  Two eyes of two patients had uncomplicated phacoemulsification and presented 16 and 20 years after surgery with spontaneous, nontraumatic haptic disinsertion from a three-piece IOL.
  
  
  RESULTS
  In one case, the disinserted haptic dislocated into the anterior chamber while the IOL optic-single haptic complex remained centered and supported within the capsular bag. Cystoid macular edema was present, but resolved after removal of the disinserted haptic. In the second case, the disinserted haptic remained within the capsular bag while the IOL optic dislocated into the anterior chamber. Removal of the IOL and exchange with a sulcus-fixated single piece IOL was required.
  
  
  CONCLUSIONS
  Nontraumatic haptic disinsertion from a three-piece IOL is a rare long-term complication after phacoemulsification.
