title: [Post-cataract surgery diplopia: etiology and treatment].
abstract: OBJECTIVE
  To know the causes and treatment of diplopia observed after cataract surgery.
  
  
  METHODS
  We make a descriptive retrospective study on 19 cases with persistent binocular diplopia following cataract surgery.
  
  
  RESULTS
  They were classified by aetiology in four groups: myotoxic effects in surgery act (47.4%), alteration in binocular vision (amblyopia, previous strabismus or long sensory deprivation) (47.4%), refractive alterations (5.2%) and previous disease. Initially, treatment with prisms, was tolerated on 47.4%; surgery was required on 36.8%, botulinicum toxin on 5.3% and penalty on 10.5% to avoid diplopia. Eventually, 36.8% of patients went on with diplopia, just only one lay equal, disappearing on 63.2% because binocular vision was recovered or suppressed by themselves or by penalty.
  
  
  CONCLUSIONS
  Diplopia after cataracts surgery, is a serious complication that surgeons must take into account. In spite of the different treatments used, it is not easy to get its disappearance.
