SimVis Vision Simulator



The SimVis is a lightweight vision simulator that can be worn alone or in a headset. The device was designed to imitate the effects of a multifocal IOL and help patients anticipate their post-cataract surgery vision.

The SimVis is not yet available on the market.

The Simultaneous Vision simulator (SimVis) is a visual demonstrator of multifocal lens designs for prospective intraocular lens replacement surgery patients and contact lens wearers. This programmable device employs a fast tunable lens and works on the principle of temporal multiplexing. The SimVis input signal is tailored to mimic the optical quality of the multifocal lens using the theoretical SimVis temporal profile, which is evaluated from the through-focus Visual Strehl ratio metric of the multifocal lens.
