Visual function after bilateral implantation of a new zonal refractive aspheric multifocal intraocular lens

TLDR: The new‐generation multifocal IOL provided adequate distance, intermediate, and, to a lesser extent, near vision with high rates of spectacle freedom.

Abstract: Purpose To evaluate visual function after bilateral implantation of a zonal refractive aspheric multifocal intraocular lens (IOL) Setting Private practice surgery center, Valencia, Spain Design Cohort study Methods Consecutive eyes with cataract had bilateral implantation of Lentis Mplus LS-312 multifocal IOLs Distance, intermediate, and near visual acuities; contrast sensitivity; defocus curves; and a quality-of-vision questionnaire, including presence of halos or dysphotopsia, were evaluated 6 months postoperatively A control group of age-matched monofocal pseudophakic patients was included to compare contrast sensitivity function Results In the multifocal group, the mean binocular corrected distance visual acuity (logMAR) was −004 ± 007 at 6 m, 011 ± 010 at 1 m, and 006 ± 007 at 40 cm The defocus curve showed little intermediate vision drop off Photopic contrast sensitivity for distance was similar to the monofocal IOL contrast sensitivity function, while photopic contrast sensitivity for near and mesopic contrast sensitivity for distance with or without glare was reduced at high frequencies The mean patient satisfaction was 809 ± 130 (scale 0 to 10); 844% of patients were completely independent of spectacles Moderate halos, glare, and night-vision problems were reported by 62%, 125%, and 156% of patients, respectively Conclusion The new-generation multifocal IOL provided adequate distance, intermediate, and, to a lesser extent, near vision with high rates of spectacle freedom Halos occurred, and other photic phenomena should be expected in a small percentage of patients Financial Disclosure No author has a financial or proprietary interest in any material or method mentioned
