Monovision and multifocal IOLs offer excellent refractive outcomes

Monovision correction and multifocal IOLs work well for correcting distance vision, with multifocal IOLs reducing the need for glasses but significantly increasing dysphotopsia for those who underwent implantation.

Monovision correction and multifocal IOLs work well for correcting distance vision, with multifocal IOLs reducing the need for glasses but significantly increasing dysphotopsia for those who underwent implantation. That’s the conclusion of research recently published in the Journal of Cataract & Refractive Surgery.

Investigators from Greece conducted a prospective randomized trial of 75 participants who had a diagnosis of senile cataract with stage 2 nuclear opalescence. Thirty-eight were assigned to the monovision group, and 37 were assigned to the multifocal IOL group. The researchers assessed uncorrected distance visual acuity (UDVA) and corrected distance visual acuity as well as Visual Function Index-14 (VF-14) scores and spectacle dependence, before surgery and 6 months afterward.

"Both techniques provided excellent refractive outcomes in UDVA and VF-14 scores," the researchers reported. Participants in the monovision group, however, demonstrated a greater need for glasses for near vision but experienced less glare than those in the multifocal group.
