NCT04059289

Brief Summary

To compare (low contrast) visual acuity (VA) and contrast sensitivity (CS) - both at intermediate distances under nighttime driving conditions in a driving simulator between patients with bilateral EYHANCE IOLs OR bilateral conventional monofocal IOLs. Visual function testing in the driving simulator will be assessed without AND with (static) glare. Additionally: Assessment of individual response times, scanpath characteristics, evaluation of test retest reliability and self-evaluation of (intermediate) vision and visual impairment related to glare.
