Epidemiology and Burden of Astigmatism: A Systematic Literature Review

Optometry 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

Journal 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 (
