title: [Dislocation of artificial lenses into the vitreous body. Long-term follow-up of 6 patients].
abstract: BACKGROUND
  Dislocation of an artificial intraocular lens (IOL) into the vitreous is a rare complication in cataract surgery. The removal of the IOL from the vitreous can be associated with various difficulties. As vitreal surgery in Latvia has been developed only during the last two years, patients with IOL dislocation prior to that time were only observed. The aim this study was the long-term observation of this patients.
  
  
  METHODS
  6 patients with dislocated IOLs in the vitreous were observed over various periods of time: 1 patient for 6 years, 2 patients for 3 years, 2 patients for 2 years and in 1 patient for 1 year. A second IOL was implanted into the anterior chamber in two cases.
  
  
  RESULTS
  In all cases the retina remained attached. Intraocular pressure was below 20 mmHg. Visual acuity was 0.4 (20/28) and 0.5 (20/40) in the two cases with secondary anterior chamber IOL. In the other cases visual rehabilitation was achieved with spectacles or contact lenses. Visual acuity was 0.7 (20/28) in one patient, 0.4 (20/50) in two patients and 0.1 (20/200) in one patient.
  
  
  CONCLUSIONS
  Dislocated artificial intraocular lenses can remain in the vitreous for a long time without serious complications, if no vitreal surgery is possible.
