SimVis Gekko simulations vs clinical data in implanted patients

We incorporated real data from commercial lenses1 obtained from literature in our visual simulator SimVis Gekko and measured defocus curves in presbyopic subjects. A very high correlation (>90%) was found between the curves of real patients implanted with the same lenses and the simulation.
