A 46-year old woman presented with a 12-month history of diplopia after being prescribed monovision contact lenses. The iatrogenic anisometropia caused decompensation of an esophoria, resulting in diplopia. A normal binocular state was reinstated with glasses, but it was necessary to incorporate prisms to achieve single vision.
