Abstract

Purpose : Combining diffractive multifocal intraocular lenses (MF-IOLs) with different near additional powers produces a customizable range of postoperative near vision. This prospective study compared the binocular vision outcomes after staged implantation of MF-IOLs with three different additional powers.

Methods : Bilateral MF-IOL implantation was performed in 56 patients at the Department of Ophthalmology, Tokyo Dental College Suidobashi Hospital. Patients with other ocular complications were excluded. In the first eye, a MF-IOL (ZMB00, Abbott Medical Optics [AMO]) with a +4.0-diopter (D) add was implanted; for the second eye, patients chose a +4.0-D, +3.25-D (ZLB00, AMO), or +2.75-D (ZKB00, AMO) add. The uncorrected and distance-corrected binocular logarithm of the minimum angle of resolution visual acuities (VAs) for distance and intermediate-to-near (1 meter and 50, 40, and 30 cm), stereovision, and contrast sensitivity were assessed at 3 months or later. The differences in the VAs among the groups were compared using the Kruskal-Wallis and Tukey’s multiple comparison tests.

Results : For the +4.0-, +3.25-, +2.75-D adds (21, 18, and 17 patients, respectively), the mean uncorrected and distance-corrected binocular VAs were -0.08/-0.11/-0.14 and -0.15/-0.17/-0.18 for distance; 0.06/0.02/0.01 and 0.06/0.00/-0.03 for 1 meter; 0.08/0.02/-0.03 and 0.05/-0.02/-0.06 for 50 cm; 0.08/0.03/0.02 and 0.02/0.00/-0.03 for 40 cm; and 0.12/0.08/0.08 and 0.08/0.07/0.06 for 30 cm. The 50-cm distance-uncorrected binocular VAs of the 2.75-D add group were significantly (P=0.001) better than the +4.0-D add group; the 50-cm distance-corrected binocular VAs of the +3.25-D and +2.75-D add groups were significantly (P=0.0164, <0.001) better than the +4.0-D add group. The stereovision values of the +4.0-, +3.25-, and +2.75-D add groups were 44.4/59.4/57.6 seconds, which did not reach significance (P=0.074). The contrast sensitivities of the three groups were normal at all spatial frequencies.

Conclusions : Bilateral implantation of MF-IOLs with different near additional powers provides better intermediate vision than implantation of MF-IOLs with the same additional powers.
