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 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.
