Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This prospective observational cohort study will compare night-driving visual difficulty and visual disturbances after bilateral implantation of an Alcon trifocal intraocular lens or an Alcon monofocal intraocular lens in adults undergoing cataract surgery. The type of intraocular lens will be selected by each participant and the treating ophthalmologist as part of routine clinical care, and will not be assigned by the investigators. Eligible participants must have a valid motor vehicle driving license and a stable history of night driving during the previous 3 months. The primary outcome will be the total score of the Visual Function and Night Driving Questionnaire (VND-Q) at 3 months postoperatively. Secondary assessments will include glare adaptation, self-rated night-driving quality and driving speed, changes in night-driving behavior, visual disturbances, distance, intermediate and near visual acuity, contrast sensitivity, whole-eye aberrations, pupil diameter, defocus performance, reading speed, spectacle independence, and participant satisfaction.
