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 develo** world …

Soft multifocal simultaneous image contact lenses have boomed in recent years due to the
growing number of presbyopic patients demanding visual solutions, allowing them 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 …

It is important to be able to measure the range of clear focus in clinical practice to advise on
presbyopia correction techniques and to optimise the correction power. Both subjective and …

This study compares the clinical through-focus visual acuity (VA) in patients implanted with
different intraocular lens (IOL) to optical bench testing of the same IOLs to evaluate the …

PURPOSE: To evaluate the visual outcomes of patients with a new diffractive trifocal
intraocular lens (IOL). METHODS: A trifocal diffractive Fine Vision IOL (Physiol, Liege …

Purpose: The aim of this study was to compare the visual outcomes of two monofocal
intraocular lenses (IOLs), with emphasis on the defocus curve. Methods: A total of 116 …

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 In recent years new models of intraocular lenses are appearing on the market
to reduce requirements for additional optical correction. The purpose of this study is to …

Purpose.: To determine the most appropriate analysis technique for the differentiation of
multifocal intraocular lens (MIOL) designs by using defocus curve assessment of visual …
