title: Diplopia after cataract surgery.
abstract: OBJECTIVE
  To evaluate the cause of diplopia after cataract surgery.
  
  
  METHODS
  Cataract surgery at 7 hospitals and examination of diplopia at a central eye hospital.
  
  
  METHODS
  This study comprised 18 eyes of 17 patients with diplopia that developed after cataract surgery in which retrobulbar anesthesia was used. The Hess screen test was done to diagnose oculomotor dysfunction.
  
  
  RESULTS
  Several cases showed superior or inferior deviation of the globe, but most patients had nonuniform disturbances of eye movement. Examination of 3 patients by the Hess chart within 1 week after surgery showed paralysis of eye muscles but an overaction at a later stage, evident by reversal of eye position 1 month later. Surgery for strabismus was performed in 6 cases. One case with diplopia improved spontaneously 3 months after cataract surgery and achieved good alignment.
  
  
  CONCLUSIONS
  The Hess screen test was useful for comparing changes in oculomotor function before and after surgery. Oculomotor dysfunction after cataract surgery may be caused directly by traumatic injury during administration of anesthesia or surgery using bridle sutures or indirectly from sensitivity to anesthetic agents.
