Metrics of retinal image quality predict optimal refractive corrections and correlate with visual
performance. To date, they do not predict absolutely the relative change in visual …

Eyes with the corneal ectasia keratoconus have performed better than expected (eg visual
acuity) given their elevated levels of higher-order aberrations that cause rotationally …

We investigated the classical question of why visual acuity decreases with decreasing
retinal illuminance by holding retinal eccentricity fixed while illumination varied. Our results …

A recent template-matching model hypothesized that simulated visual acuity loss with
uncorrected refractive errors may be recovered by adding temporal defocus fluctuations up …

The aim of this work is to evaluate the performance of a novel algorithm that combines
dynamic wavefront aberrometry data and descriptors of the retinal image quality from …

PURPOSE This study describes the correlation between the contrast sensitivity function
(CSF) and the modulation transfer function (MTF) in a sample of young and informed …

Optical defocus in human eyes is seldom steady during naturalistic steady-state viewing. It
fluctuates by 0.3 to 0.5 diopters (D) from accommodative microfluctuations and by 1.5 to 2.5 …

Purpose: The purpose of this study was to determine changes in spatial and depth vision
with increasing severity of keratoconus and to model the structure-function relationship to …

Many experimental studies show that metrics of visual image quality can predict changes in
visual acuity due to optical aberrations. Here we use statistical decision theory and Fourier …

We propose, implement, and validate a new objective method for predicting the trends of
visual acuity through-focus curves provided by specific optical elements. The proposed …
