Abstract

It has been well known that wavefront aberrations of the eye are dynamic, changing continuously over time due to factors like accommodation, blinking, pupil size, tear film stability, etc. The goal of this work is to describe the developed methodologies for computing these dynamic aberrations. In this study, we present some preliminary results of real time measurement of monochromatic ocular aberrations during accommodative changes measured experimentally using a wavefront sensor.
