title: [Light scattering observed on the surface of acrylic intraocular lenses ten years after implantation].
abstract: OBJECTIVE
  To report the long-term status of acrylic intra-ocular lenses.
  
  
  METHODS
  We describe two cases of increased light scattering on the surface of acrylic intraocular lenses ten years after implantation. The scattering was non-symptomatic and visual acuity was normal. Biomicroscopy and a Scheimpflug photography system showed that the scattering apparently derived from the anterior surface of the lens, but no deposit or membranous structure was observed on the lens surface.
  
  
  CONCLUSIONS
  Surface scattering from acrylic intra-ocular lenses is a new finding in long-term observations. A possible etiology may be structural changes of the internal polymer.
