About

Primary objective of this study is to introduce a modified luminous efficiency function that addresses the distinct total eye light transmittance of patients who underwent pseudophakic presbyopic correction with extended-depth of focus (EDOF) intraocular lenses (IOLs) implantations.

Full description

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

Enrollment: 100 estimated patients

Sex: All

Ages: 45 to 75 years old

Volunteers: Accepts Healthy Volunteers
