6 COMSOL MULTIPHYSICS OCTOBER 2018 3D PARAMETRIC FULL EYE MODEL GIVES 20+ YEARS OF BETTER VISION A research team at Kejako, a medical device company based in Switzerland, share how they are using multiphysics simulation to develop an innovative solution that will delay the need for reading glasses or invasive surgery for decades. PRESBYOPIA IS A NATURAL EFFECT of aging in which a loss of elasticity in the lens of the eye causes far-sightedness. As a result, your visual accommodation gradually declines, as your eyes can no longer effectively change their optical power to maintain a clear image or focus on an object as its distance varies.
