title: Non-organic Visual Loss in Patients with Multifocal Intraocular Lenses.
abstract: OBJECTIVE
  To report non-organic visual loss (NOVL) following cataract surgery with multifocal intraocular lens (IOL) implantation.
  
  
  METHODS
  After reviewing consecutive cases of NOVL diagnosed by a single neuro-ophthalmologist over a one year period, two patients reported herein attributed their visual symptoms to cataract surgery and multifocal IOL implantation.
  
  
  RESULTS
  In both patients variability was noted in visual function and kinetic perimetry demonstrated non-organic visual field loss. Initially, refractive surgeons considered lens exchange, which was avoided after neuro-ophthalmic evaluation in both cases.
  
  
  CONCLUSIONS
  This report should alert cataract and refractive surgeons to the possibility of NOVL as an explanation for dissatisfaction after cataract surgery with multifocal IOL implantation.
