It is well known that the wavefront error (WFE) of the eye varies from individual to individual
with pupil diameter (PD) and age. Numerous studies have been proposed evaluating the …

We determined the degree to which change in visual acuity (VA) correlates with change in
optical quality using image-quality (IQ) metrics for both normal and keratoconic wavefront …

The visual image quality metric the visual Strehl ratio (VSX) combines a comprehensive
description of the optics of an eye (wavefront error) with an estimate of the photopic neural …

Visual image quality metrics combine comprehensive descriptions of ocular optics (from
wavefront error) with a measure of the neural processing of the visual system (neural …

ABSTRACT PURPOSE: Root mean square (RMS) wavefront error may not be the best
metric for predicting a patient's visual function; other metrics should be considered. We …

The expansion of wavefront-sensing techniques redefined the meaning of refractive error in
clinical ophthalmology. Clinical aberrometers provide detailed measurements of the eye's …

Purpose. The purpose of this study is to determine the ability of single-value metrics of
retinal image quality of the eye to predict visual performance as measured by high (HC) and …

purpose. To study the relationship between visual acuity (VA) and the eye's optical quality in
subjects with normal and excellent spatial vision. VA ranged from decimal values of 1.0 …

The depth of focus (DOF) can be defined as the variation in image distance of a lens or an
optical system which can be tolerated without incurring an objectionable lack of sharpness …

By comparison to man-made optical systems, the human eye has relatively low optical
quality. Consequently, standard industrial metrics of optical quality, such as RMS wavefront …
