Purpose Following the recognition, some 80 years ago, that the accommodation of the eye is
not stable but fluctuates over a range of about±0.5 D, mainly at frequencies of up to a few …

Monochromatic aberrations of the eye principally originate from the cornea and the
crystalline lens. Aberrometers operate via differing principles but function by either analysing …

Purpose: To evaluate the intrasubject repeatability of the ocular aberrometry obtained with a
new ocular pyramidal aberrometer technology in a sample of normal eyes. Methods: A total …

We present an adaptive optics spectral domain optical coherence tomography (AO-SDOCT)
with a long focal range by active phase modulation of the pupil. A long focal range is …

Conventional optical systems usually provide best image quality on axis, while showing
unavoidable gradual decrease in image quality towards the periphery of the field. The …

Clinical relevance Optical approaches to modulating near work may be beneficial in
arresting the progression of myopia Background To explore whether a long-distance optical …

PURPOSE: To evaluate the intrasubject repeatability of the internal aberrometry obtained
with a new integrated aberrometer in a sample of normal eyes to assess its clinical …

Ocular monochromatic aberrations display dynamic behavior even when the eye is fixating
on a stationary stimulus. The fluctuations are commonly characterized in the frequency …

Purposes: This study discussed the accommodative response and pupil size of myopic
adults using a double-mirror system (DMS). The viewing distance could be extended to …

It has been proposed that the accommodation system could perform contrast discrimination
between the two dioptric extremes of accommodative microfluctuations to extract directional …
