System for objective assessment of the accommodation response during subjective refraction
Autor: Carlos E. García-Guerra, Joan A. Martínez-Roda, Juan C. Ondategui-Parra, Aina Turull-Mallofré, Mikel Aldaba, Meritxell Vilaseca
Purpose: To evaluate a system based on a Hartmann–Shack wavefront sensor attached to a phoropter that allows the user to obtain real-time information about the refractive state of the eye and the accommodation response (AR). Methods: The objective

A previous work has reported a methodology to quantify intraocular scattering using a high sensitivity double-pass instrument with a robust index, the frequency scatter index. The purpose of our study was to evaluate an adaptation of the frequency sc

Double-pass systems rely on backscattering of light by the human ocular fundus to assess the optical quality of the eye. In this work, we present a method to reduce double-pass image degradation caused by undesired multiple scattering effects in the
