To evaluate the visual performance after bilateral implantation of multifocal intraocular lenses.
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.

Binocular contrast sensitivity (CS) under photopic, mesopic, and mesopic with glare lighting conditions
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
Binocular contrast sensitivity (CS) was measured under photopic, mesopic (0.167 cd/m²), and mesopic with glare lighting conditions by means of the "Frankfurt-Freiburg Contrast and Acuity Test System" (FF-CATS)
Time frame: Measured 3 month after lens surgery
Defocus curve testing
Defocus curve (monocular and binocular) was tested from -5.0 D to +2.0 D in 0.5 D steps under photopic lighting conditions (ETDRS).
Time frame: Measured 3 month after lens surgery
