The Method for Evaluating Ametropia and the Depth of Focus of the Eye

The need is established for measuring pseudo-accommodation (the depth of focus of the eye) when a standard artificial or accommodative lens is implanted into the eye. It is specified the need for analyzing the impact of aberrations of a measuring device’s elements as well as the pupil’s diameter onto the accuracy of ametropia and pseudo-accommodation measurements by the method, proposed by the authors. In this study, a computer simulation is applied for an optical system of the measuring device and an ametropic eye with a diffuse-scattering retina.
