title: [Unilateral congenital cataracts removed early: long-term refractive changes].
abstract: OBJECTIVE
  Predict long-term refractive changes after primary lens implantation for unilateral congenital cataract in order to know the intraocular lens power to use to obtain best functional results.
  
  
  METHODS
  This retrospective study analyzed 53 children with unilateral congenital cataract operated on with primary intraocular lens implantation, with a mean follow-up of 6.8 years. The mean age at surgery was 2.98 years.
  
  
  RESULTS
  The mean myopic shift per year was -0.83 D/year. Children operated on before the age of 2 years had a mean myopic shift of -9.15 D, and others presented -2.13 D. The variability of myopic shift decreased with age. The mean visual acuity was +0.25 logMAR. Four intraocular lenses were changed because of substantial anisometropia.
  
  
  CONCLUSIONS
  Early surgery with primary implantation and intensive amblyopia treatment provide good long-term visual results. Long-term refractive changes of very young children operated on for unilateral congenital cataract is extremely variable. Changing the intraocular lens is conceivable when substantial anisometropia slows down amblyopia rehabilitation.
