title: [Long-term follow-up of visual functions after pediatric cataract extraction and intraocular lens implantation].
abstract: OBJECTIVE
  To assess the visual acuity and binocular function of children after pediatric cataract extraction and intraocular lens implantation.
  
  
  METHODS
  47 children with 68 eyes (< 13 years old) were included in the study: 12 children with monolateral traumatic cataract, 14 children with monolateral congenital cataract and 21 children with bilateral congenital cataract. Cataract type, cataract extent, age at surgery and presence of strabismus and nystagmus and the best corrected distant visual acuity (BCDVA) before surgery were recorded and as well. In addition, the best corrected near visual acuity (BCNVA) and binocular function were followed up for an average of (41.3 +/- 12.3) months. Statistical analysis was used to define factors that correlated with achieving good visual acuity and binocular function.
  
  
  RESULTS
  BCDVA and BCNVA were 0.5 or better in 34 eyes (50.0%) and a good binocular function was achieved in 18 children (38.3%). Age at surgery, extent of cataract, absence of strabismus and nystagmus were significant for good BCDVA. Age at surgery, absence of strabismus and nystagmus, good BCDVA were significant for good binocular function.
  
  
  CONCLUSIONS
  Good visual acuity and binocular function can be achieved after pediatric cataract extraction and intraocular lens implantation. Multiple factors correlated with achieving good visual function such as timing of surgery, type and extent of cataract, absence of strabismus and nystagmus etal.
