Tunable lenses are becoming ubiquitous, in applications including microscopy, optical
coherence tomography, computer vision, quality control, and presbyopic corrections. Many …

A novel double-pass instrument and its data analysis method for the measurement of central
and peripheral refraction is presented and validated in a group of healthy subjects. The …

Purpose To conduct a clinical validation of a virtual reality-based experimental system that is
able to assess the spherical subjective refraction simplifying the methodology of ocular …

Purpose: To study the accommodative dynamics for predictable and unpredictable stimuli
using manual and automated accommodative facility tests Materials and Methods …

Recently, the development of motion-free 3D microscopy utilizing focus tunable lenses (FTL)
has been rapid. However, the downgrade of optical performance due to FTL and its gravity …

We present a system that integrates a double-pass (DP) instrument and a Hartmann–Shack
(HS) wavefront sensor to provide information not only on aberrations, but also on the …

Speckle arises in double-pass images when coherent light is scattered by the retina. Since
this noise degrades the images that are used to characterize the eye, there is special …

Double-pass systems rely on backscattering of light by the human ocular fundus to assess
the optical quality of the eye. In this work, we present a method to reduce double-pass image …

We have studied the possibility of improving the performance, simplifying, and reducing the
cost of a double-pass system by the use of alternative technologies. The system for …

PURPOSE The purpose of this study was to investigate the effect of stimulus' time,
magnitude, and direction predictability, as well as their interactions, on accommodation …
