The autonomic nervous system influences numerous ocular functions. It does this by way of
parasympathetic innervation from postganglionic fibers that originate from neurons in the …

Lutein is a non-provitamin A dietary carotenoid found in dark green leafy vegetables, corn,
eggs, and avocados. Among the carotenoids, lutein and its isomer, zeaxanthin, are the only …

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: To determine whether implantation of an intraocular lens (IOL) with a modified
anterior surface designed to compensate for the positive spherical aberration of the cornea …

PURPOSE: To evaluate the information assessed with the LADARWave wavefront

Several laser and non-laser refractive surgical procedures have been used to modify the
shape of the cornea and correct myopia, hyperopia, astigmatism, and presbyopia …

A certain percentage of patients complain of “glare” at night after undergoing a refractive

OBJECTIVE: The purpose of this study was to determine objectively the changes in optical
aberrations induced by the progressive tear film irregularity after a blink and their effects on …

We introduce tailored displays that enhance visual acuity by decomposing virtual objects
and placing the resulting anisotropic pieces into the subject's focal range. The goal is to free …
