title: [Experimental study of glistening in silicone intraocular lenses].
abstract: OBJECTIVE
  To assess the whether glistening(GP) occurs on silicon lenses.
  
  
  METHODS
  ALLERGAN, SI-40NB and CANON STAAR, AQ110NV lenses(Alcon MA60BM control). The lenses were immersed in 50 degrees C physiological saline solution for 2 hours, and then immersed in 35 degrees C physiological saline solution. Changes in the lens were observed regularly with a slit lamp microscope until the 90th day.
  
  
  RESULTS
  Numerous microvacuoles of 10 microns diameter occurred in the MA60BM and of several microns in the SI40NB. Some clouding was seen in the AQ110 NV.
  
  
  CONCLUSIONS
  The presence of numerous microvacuoles in the SI40NB means there may be GP. The light clouding in the AQ110NV that was resolved with drying is thought to be due to particles in the material which cause discoloration.
