Non-organic Visual Loss in Patients with Multifocal Intraocular Lenses

Purpose: 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 neuroophthalmologist 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.
