title: CALCIFICATION OF A HYDROPHILIC ACRYLIC INTRAOCULAR LENS AFTER PARS PLANA VITRECTOMY.
abstract: OBJECTIVE
  Anterior surface calcification of a hydrophilic acrylic intraocular lens (IOL) associated with iatrogenic exposure of air after an uncomplicated pars plana vitrectomy is described.
  
  
  METHODS
  The clinical and histochemical findings of a patient who developed postoperative opacification of a hydrophilic acrylic intraocular lens are retrospectively reviewed.
  
  
  RESULTS
  A 63-year-old woman developed fine granular opacifications on the anterior surface of the intraocular lens 8 months after a pars plana vitrectomy with iatrogenic exposure of air. The intraocular lens was explanted and histochemical analysis confirmed the presence of calcium.
  
  
  CONCLUSIONS
  Physicians should be aware of this complication and be cautious about the use of intraocular gas in either the front or the back of the eye in patients with hydrophilic acrylic intraocular lenses.
