An approach is presented to design different types of Intraocular lenses (IOLs) with a uniform
optimization algorithm. An improved sinusoidal phase function is proposed to realize …

Purpose.: To compare, as a function of pupil size, the through-focus performance and halo
features of four diffractive intraocular lenses (IOLs). Methods.: Three diffractive bifocal IOLs …

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 …

Background Presbyopia has become a global disease affecting the world's aging
population. Among various treatments, cataract extraction and intraocular lens (IOL) …

Purpose: We present the first physiological evaluation of the use of the light sword lens
(LSL) for presbyopia compensation. The LSL is an axially asymmetric optical element …

La catarata o pérdida de transparencia del cristalino es un trastorno de la visión muy
invalidante que ha sufrido la humanidad a lo largo de la historia. En las últimas décadas se …

Purpose: We propose and evaluate the modifications of a light sword lens (LSL) to obtain
better performance for distance vision while maintaining good operation for near and …

We explore the possibility of extending the depth of focus of an imaging lens with an
asymmetric quartic phase-mask, while keeping the aberration within a relatively low level …

The depth of focus (DOF) defines the axial range of high lateral resolution in the image
space for object position. Optical devices with a traditional lens system typically have a …

The paper presents imaging properties of the peacock eye optical element. Its abilities for
imaging with extended depth of field is illustrated experimentally in monochromatic as well …
