Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study evaluates the visual performance after bilateral implantation of multifocal intraocular lenses (IOL). This prospective study is performed at the department of Ophthalmology, Goethe University, Frankfurt, Germany.

Patients who received bilateral implantation of a multifocal intraocular lens pre-enrollment were included consecutively. Exclusion criteria were previous ocular surgeries excluding cataract surgery and refractive lens exchange, regular corneal astigmatism of \>1.5 diopter, and ocular pathologies or corneal abnormalities. At 3 months postoperative examination included manifest refraction; monocular and binocular uncorrected (UCVA) and distance-corrected (DCVA) visual acuity in at far, intermediate at near distance (logMAR); slit-lamp examination. 3 months postoperatively defocus testing, binocular contrast sensitivity (CS) under photopic and mesopic conditions, and a questionnaire on subjective quality of vision, optical phenomena, and spectacle independence were performed.
