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

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 …

Purpose: To evaluate and compare the visual outcomes and ocular optical performance of
the PanOptix trifocal intraocular lens (IOL) and Symfony extended range of vision IOL …

Aims Previous studies and community information about everyday difficulties in age-related
macular degeneration (AMD) have focussed on domains such as reading and driving. Here …

Slightly off-axis digital holographic microscopy (SO-DHM) has recently emerged as a novel
experimental arrangement for quantitative phase imaging (QPI). It offers improved …

Standard optical systems in ophthalmology are strictly dedicated either to retinal or to
anterior segment imaging due to the refractive properties of the eye. We demonstrate a …

Visual performance depends on polar angle, even when eccentricity is held constant; on
many psychophysical tasks observers perform best when stimuli are presented on the …

The optical quality of a set of IOLs (modeling set: one monofocal and two bifocals) was
assessed through focus by the area under the modulation transfer function (MTFa) metric …

Purpose.: On average, myopic eyes present a relative hyperopia in the peripheral retina.
This has been associated with the possibility that by modifying the peripheral refraction, the …
