Presbyopia is a global problem affecting over a billion people worldwide. The prevalence of
unmanaged presbyopia is as high as 50% of those over 50 years of age in developing world …

Cataract surgery is the most common surgical procedure performed in medicine. In the 2015
over 20 million surgeries were carried out worldwide, of which 3.6 million in the United …

Lens design is of paramount importance in the evolving world of technology, where
compactness and high optical performance are a necessity, ranging from smartphones and …

The most fundamental aspect of a contact lens is its optics; the manner in which the
refraction of light is managed to optimise vision to the clinical benefit of the lens wearer. This …

In modern machine vision systems high-end lens objectives allow superior imaging on state-
of-the-art sensor arrays due to highly corrected optical aberrations and large apertures. The …

We present an experimental off-axis optical holographic scheme employing a digital
micromirror device (DMD) as projecting media instead of a liquid crystal spatial light …

This work presents the first models of light sword intraocular lenses (LS IOLs) with angularly
modulated optical power. We performed an experimental, comparative study with multifocal …

We propose, implement, and validate a new objective method for predicting the trends of
visual acuity through-focus curves provided by specific optical elements. The proposed …

Multifocal lenses comprising progressive power surfaces are commonly used in contact and
intraocular lens designs. Given a visual performance metric, a wavefront engineering …

Introduction: The natural loss in accommodation that occurs with age means that all those
who are emmetropic, or have their distance refractive error corrected in some way, start to …
