![]() We believe that this mobile model eye can be used to evaluate how the real world appear to a patient with a multifocal IOL, to explain multifocal function of the IOLs, and possible complications in the patients, before performing a surgery. In the night vision, there was a mild or severe halo around light sources compared to those with the monofocal IOL. Far objects appeared either similarly clear or slightly hazier (depending on the IOL model) than those with the monofocal IOL. Two multifocal IOLs showed definite multifocal function. In the car, we took pictures of the street and a cell phone in turn to check the multifocal function of the lenses. For an indoor analysis, we approached the Early Treatment Diabetic Retinopathy Study (ETDRS) chart to the model eye from a distance of 95 cm to check the multifocal function of the lenses. ![]() At night, we stood on a road and took pictures to see how the traffic lights and headlights of cars looked. We went outside to take a picture of the scenery. A monofocal IOL (Tecnis monofocal IOL) and two diffractive multifocal IOL (ReSTOR, Tecnis multifocal IOL) were used in the study. ![]() The mobile model eye was composed of an artificial cornea, IOL, IOL chamber, and a camera. To show how the world appear to patients with multifocal intraocular lens (IOL) using a novel mobile model eye.
