Binocular simultaneous vision simulatorvalidation and implementation of the sim+vis technology in the clinic

Abstract

With aging, the crystalline lens loses its ability to accommodate (a condition known as presbyopia), making necessary to use optical aids to see at near. Today, a wide variety of optical solutions for presbyopia (both surgical and non-surgical) are available, aiming at providing patients with satisfactory functional vision at different distances.Prescribing presbyopia solutions is a difficult problem, as every patient has different needs, and it is difficult to convey to the patient how his/her visual quality is going to see with different corrections. Besides spectacles (progressive lenses or single focus positive lenses), multifocal contact lenses and intraocular lenses have emerged as popular solutions. Multifocal contact lenses are non-surgical solutions (and therefore easily reversible). However, the fitting process is lengthy. On the other hand, surgical solutions such as multifocal intraocular lenses, cannot be tried before implantation.Visual simulators meet the need for non-invasive trying different corrections prior to prescription or implantation. The SimVis Gekko (based on the Sim+Vis technology) is the first see-through and binocular simulator, allowing patients to see the real world through different binocular combinations of monofocal and multifocal corrections...
