Visual Performance of Center-distance Multifocal Contact Lenses Fit Using a Myopia Control Paradigm

SIGNIFICANCE PURPOSE The purpose of this study was to examine the visual performance of center-distance MFCLs in nonpresbyopic adults under different illumination and contrast conditions compared with a single-vision contact lens (SVCL). METHODS Twenty-five adult subjects were fit with three different lenses (CooperVision Biofinity D MFCL +2.50 add, Visioneering Technologies NaturalVue MFCL, CooperVision Biofinity sphere). Acuity and reading performance were evaluated. RESULTS A statistically significant difference in high-contrast distance acuity was observed (Biofinity, −0.18 ± 0.06; Biofinity MFCL, −0.14 ± 0.08; NaturalVue MFCL, −0.15 ± 0.03; repeated-measures [RM] ANOVA, P = .02). Under mesopic, high-contrast conditions, MFCLs performed worse than SVCLs (Biofinity, −0.05 ± 0.091; Biofinity MFCL, +0.03 ± 0.09; NaturalVue MFCL, +0.05 ± 0.091; RM-ANOVA, P
