Comparison of a Presbyopia-Correcting Supplementary Intraocular Lens Combination and a Capsular-Bag Lens: An In Vitro Study

open access: yesDiagnostics, 2023
We evaluated the optical quality of two approaches to trifocality: polypseudophakia versus monopseudophakia. The combination (polypseudophakia) of a monofocal Basis Z B1AWY0 and AddOn Trifocal A4DW0M intraocular lens (IOL) was compared to using one Basis

Epidemiology and Burden of Astigmatism: A Systematic Literature Review

open access: yesOptometry and Vision Science, Volume 100, Issue 3, Page 218-231, March 2023., 2023
SIGNIFICANCE This is the first literature review to report the epidemiology, patient burden, and economic burden of astigmatism in the general adult population. The unmet needs of astigmatism patients with coexisting ocular conditions (cataract, glaucoma, dry eye, presbyopia, or macular degeneration) and risks associated with untreated astigmatism are ...

Visual Performance of Eyes with Residual Refractive Errors after Implantation of an Extended Vision Intraocular Lens

open access: yesJournal of Ophthalmology, Volume 2023, Issue 1, 2023., 2023
Background. To analyze the tolerance on distance vision of different combined residual astigmatic situations in patients implanted with a novel wavefront shaping extended depth of focus (EDoF) intraocular lens (IOL). Methods. The study included patients implanted with the Acrysof® IQ Vivity® IOL. Uncorrected (UDVA) and corrected distance visual acuity (

Clinical Outcomes with Extended Depth of Focus Intraocular Lenses in Cases in Which Multifocal Lenses Are Not Primarily Recommended

open access: yesJournal of Ophthalmology, Volume 2023, Issue 1, 2023., 2023
Purpose. The purpose of the study is to evaluate the visual and patient‐reported outcomes of patients undergoing cataract surgery with implantation of an extended depth of focus (EDOF) intraocular lens (IOL) who were not primarily good candidates for multifocal IOL implantation. Methods.

The Value of Static Perimetry in the Diagnosis and Follow‐up of Negative Dysphotopsia

open access: yesOptometry and Vision Science, Volume 99, Issue 8, Page 645-651, August 2022., 2022
SIGNIFICANCE There is a clinical need for a quantitative test to objectively diagnose negative dysphotopsia, especially because the diagnosis is generally assessed using patients' subjective descriptions. In the search of a clinical test to objectify the shadow experienced in negative dysphotopsia, this study excludes static perimetry as suitable ...

Optimising curve fitting techniques to look for standardisation of the analysis of defocus curves derived from multifocal intraocular lenses

open access: yesOphthalmic and Physiological Optics, Volume 42, Issue 4, Page 887-896, July 2022., 2022
Abstract Introduction To establish the most appropriate curve fitting method to allow accurate comparison of defocus curves derived from intraocular lenses (IOLs). Methods Defocus curves were plotted in five IOL groups (monofocal, extended depth of focus, refractive bifocal, diffractive bifocal and trifocal).
