Luminous Efficiency Function V(λ)' of Patients That Underwent Pseudophakic Presbyopic Corrections

Presbyopia Clinical Trial

Official title:
Introduction of a Modified Luminous Efficiency Function V(λ)' That Addresses Total Light Transmittance of Patients That Underwent Pseudophakic Presbyopic Corrections

Clinical Trial Summary

Primary objective of this study is to construct and validate a modified luminous efficiency function that addresses the distinct total eye light transmittance of patients that underwent bilateral pseudophakic presbyopic correction with trifocal intraocular lenses (IOLs) implantations.

Clinical Trial Description

Present study aims to identify in which degree multifocal IOLs modify eye light transmission and estimate the necessary task and environmental lighting adjustment in order to address lighting needs of patients following bilateral pseudophakic presbyopic corrections. Specifically, the aim of this study is to identify the minimum light intensity in which patients that underwent pseudophakic presbyopic correction with trifocal IOLs can reach their maximum visual acuity (measured when lights are at the 100% lighting level) ;
