Abstract
Purpose :
To compare the visual performance of a bifocal intraocular lens (IOL) (ZMB00) and a rotationally asymmetric multifocal with +1.5 diopters near addition intraocular lens (IOL) (Lentis Comfort LS-313 MF15 [Oculentis GmbH]).
Methods :
We evaluated postoperative parameters 10 weeks after the last surgery in cataract patients who underwent bilateral ZMB00 or LS-313 MF15 implantation from August 11, 2011, to March 26, 2020, with the right and left lenses implanted within 3 months of each other.
Results :
The study enrolled 1774 eyes of 887 patients. The bifocal group comprised 1326 eyes of 663 patients (67.0 ± 7.8 years; females/males, 518/145), and the rotationally asymmetric multifocal group comprised 448 eyes of 224 patients (73.6 ± 7.0 years; females/males, 125/99). Uncorrected near visual acuity was significantly better and the higher-order aberrations (ocular/internal, scaled to a pupil size of 4 mm) (WF_4_post_O_TotalHOA/Third/Fourth/Trefoil/Coma/Tetrafoil/Spherical, WF_4_post_I_TotalHOA/Third/Trefoil/Coma/Tetrafoil/Spherical) were significantly smaller, and distance/near spectacle independence were significantly better in the bifocal group (p<0.00068, Wald test). Contrast sensitivity (6.3/4.0/2.5/1.6/1.0/0.7 degrees), and contrast sensitivity with glare (4.0/2.5/1.6/1.0/0.7 degrees) were significantly better in the rotationally asymmetric multifocal group (p<0.00068, Wald test).
Conclusions :
The two IOL groups had different characteristics in terms of uncorrected near visual acuity, the higher-order aberrations, distance/near spectacle independence, and contrast sensitivity with/without glare.
