Micromonovision with EDOF IOL reduces photic phenomena

HONOLULU — Visual function and satisfaction were better in patients targeted for micromonovision with implantation of an extended depth of focus IOL than in patients targeted for emmetropia with the same lens or targeted for emmetropia with a diffractive multifocal lens, according to a poster presented here.
Furthermore, the incidence of rainbow halos, distinguished by patients as having distinct rings, was statistically significantly greater in the group targeted for emmetropia with the multifocal lens (P = .033), Youngsub Eom, MD, of the Korea University College of Medicine, told Healio.com/OSN.
In the study, Eom and colleagues looked at clinical outcomes of 60 eyes of 30 consecutive patients: 10 patients implanted with the Tecnis Symfony ZXR00 +1.75 D IOL with intended micromonovision, 10 implanted with the same lens targeted for emmetropia and 10 implanted with the Tecnis multifocal ZKB00 +2.75 D IOL targeted for emmetropia (all Johnson & Johnson Vision).
Near, intermediate and distance visual acuity were evaluated, as were patient satisfaction and need for spectacle correction. No patients in the monovision group required spectacles for near vision, whereas one patient in the ZKB00 emmetropia group and five in the ZXR00 emmetropia group did (P = .027).
“The implantation of the extended range of vision IOLs with +1.75 D add power with intended micromonovision seems to provide superior near or intermediate visual acuity without deteriorating visual symptoms as compared with the extended range of vision IOLs or diffractive bifocal IOLs with intended emmetropia for both eyes,” the authors wrote. “In addition the extended range of vision IOLs, which have achromatic technology as well as lower add powers tended to show a lower incidence of rainbow halos than did the diffractive bifocal IOLs.“ – by Patricia Nale, ELS
