Colorectal cancer, the third most prevalent cancer globally, contributes significantly to
mortality rates, with over 1.9 million reported cases and nearly 935,000 fatalities annually …

Contrast detection thresholds are elevated with optical quality loss in keratoconus. This
study hypothesized that suprathreshold contrast perception is also impaired in keratoconus …

Purpose To determine 1) the relative differences in optical quality of keratoconic eyes fitted
with four routinely used CL designs and 2) the Zernike coefficients in the residual wavefront …

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 …

The intricate interrelationships between visual acuity (VA) and stereopsis depend on an
array of factors, incorporating the nature of vision impairment, its manifestation (monocular …

PURPOSE Interocular differences in image quality, characterized by dissimilar contrast loss
and phase shifts, are implicated in stereoacuity loss in keratoconus. This study determined …

Increased lower-and higher-order wavefront aberrations and the associated loss in image
quality due to corneal distortions are demonstrated in keratoconus. This loss in image …

Background and aims: Keratoconus is an ocular condition that causes a change in corneal
shape and consequently degrades the retinal image quality and visual function. Despite …

Significance: The measurement of the visual acuity is often the basis of the end-point of the
refraction. The recorded value may influence the legal, medical and financial status of a …
