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

A quarter century ago, we were limited to a macroscopic view of the retina inside the living
eye. Since then, new imaging technologies, including confocal scanning laser …

Purpose To propose a new objective scatter index (OSI) based in the analysis of double-
pass images of a point source to rank and classify cataract patients. This classification …

The human eye is a relatively simple optical instrument. This limits the quality of the retinal
image affecting vision. However, the neural circuitry seems to be exquisitely designed to …

Compared to most ophthalmic technologies, adaptive optics, or AO, is relatively young. The
first working systems were presented in 1997 and, owing in part to its complexity, the …

We explored the relative changes in ocular, corneal, and internal aberrations associated
with normal aging with special emphasis in the role of ocular alignment and lens shape …

Handbook of Visual Optics offers an authoritative overview of encyclopedic knowledge in the
field of physiological optics. It builds from fundamental concepts to the science and …

Ocular scattering is an optical phenomenon that degrades the retinal image in the human
eye, similar to the effects of ocular aberrations or diffraction. However, there is still a lack of …

Background Vision-dependent mechanisms play a role in myopia progression in childhood.
Thus, we investigated the distribution of ocular and corneal higher-order aberrations (HOAs) …

Purpose To compare the objective assessment of lens density by 2 systems (double-pass
Optical Quality Analysis System and Pentacam Scheimpflug) in eyes with age-related …
