There is a critical need for tools that increase the accessibility of eye care to address the most common cause of vision impairment: uncorrected refractive errors. Due to the global shortage of eye care professionals, it is often difficult, particularly in low-resource settings, to obtain accurate prescriptions for eyeglasses that would effectively correct refractive errors and restore good vision. At MEDIC we have developed together with PlenOptika Inc. (MA, USA) and Aurolab (India) an innovative device that addresses this massive problem by significantly simplifying and speeding up the refraction process for prescribing eyeglasses.

SimVis will have a major clinical impact in the field of presbyopia corrections, as it holds potential to change the way these corrections are prescribed: This technology allows the patient for first time to experience the real world through multifocal corrections before surgery, so the patients can decide what correction will fit better their expectations before intra-ocular lens implantation. MEDIC is helping to develop this Technology in collaboration with the VioBio Lab (Instituto de Optica Daza de Valdes, CSIC, Spain) and the Spin-off Company 2EyesVision.
