title: [Nd: YAG laser clearance of the anterior surface of intraocular lenses].
abstract: OBJECTIVE
  To assess the efficacy and safety of Nd: YAG laser in clearing the anterior fibrinous membrane of posterior chamber intraocular lens (IOL).
  
  
  METHODS
  Twenty-four eyes with the anterior fibrinous membrane of posterior chamber IOL were treated by Nd: YAG laser with the principle of "Low energy and de-focus" from 1997 to 1999 in Peking Union Medical College Hospital. Visual acuity, intraocular pressure (IOP) and anterior segment of the eye were followed after the laser treatment.
  
  
  RESULTS
  Nd: YAG laser successfully cleared the anterior fibrinous membrane of IOL and IOLs were not damaged in all 24 eyes. The visual acuity was improved in 83.3% of the eyes. The IOP temporarily raised to above 21 mm Hg in 37.5% of the eyes. Topical steroids were used for the control of the intraocular inflammation in anterior segment after laser treatment.
  
  
  CONCLUSIONS
  The anterior membrane of IOL can successfully and safely be cleared by Nd: YAG laser with the principle of "low energy and de focus".
