Reading Speed and Visual Acuity in Photopic and Mesopic Conditions After Bilateral Implantation of Diffractive Multifocal Intraocular Lenses

Standard VA testing may underestimate functional limitations of multifocal IOLs under mesopic conditions. The substantial loss of reading speed suggests that mesopic near vision is impaired. Low luminance reading speed is a practical, patient-relevant endpoint and should be considered in IOL evaluations.
