title: Secondary posterior chamber intraocular lens implantation in children.
abstract: BACKGROUND
  Primary intraocular lens (IOL) implantation after cataract aspiration is a widely accepted means of correcting pediatric aphakia. However, little is available in the literature on secondary IOL implantation in children. We present our experience over the past 6 years.
  
  
  METHODS
  The charts of 57 aphakic children (61 eyes) who underwent secondary posterior chamber IOL implantation between January 1989 and April 1996 were reviewed. In general, these children were either intolerant of or noncompliant with their contact lenses. An attempt was made to correlate visual outcome with patient variables. Evaluation of the ciliary sulcus structure was made in selected patients by ultrasonographic biomicroscopy to reveal any changes resulting from the presence of the IOL haptic in the sulcus.
  
  
  RESULTS
  The age range at the time of surgery was 2 to 16 years (mean 8 y). Mean follow-up was 14 months (range 6 to 48 months). Forty-two percent of the patients had a best-corrected visual acuity of 20/40 or better and 78% saw better than 20/80. Posterior capsular opacification occurred in 10 eyes, 8 of which required neodymium:yttrium-aluminum-garnet laser capsulotomy. No major complications occurred. Ciliary sulcus evaluation by biomicroscopy did not reveal any significant ciliary body or scleral erosion. No changes were noted when the implanted sulcus was compared with the normal contralateral side.
  
  
  CONCLUSIONS
  Although follow-up was short, this review suggests that secondary posterior chamber IOL implantation is a safe alternative when other methods of correcting pediatric aphakia fail.
