Visual Acuity After the Combined Binocular Implantation of +2.5 Diopters and +3.0 Diopters ReSTOR Multifocal Intraocular Lenses.

Evaluation of the Visual Acuity After the Implantation of a ReSTOR +2.5 Diopters Intraocular Lens (ReSTOR SV25T0) in the Distance Dominant Eye, in Combination With a +3.0 Diopters ReSTOR Intraocular Lens (ReSTOR SN6AD1) in the Fellow Eye.

The objective of this study is to assess the visual outcome after the combined binocular implantation of +2.5 D and +3.0 D apodized diffractive multifocal intraocular lenses.

Bifocal multifocal intraocular lenses (MIOL) are effective in achieving good uncorrected visual acuities in the distance and the near. However, the intermediate vision is of increasing relevance for everyday's life. Several multifocal intraocular lenses have been developed to improvement intermediate vision. Nonetheless, those systems still possess adverse photic effects and do not garantuee spectacle independence. Therefore, the combination of a lower-addition bifocal intraocular lense in the distance-dominant eye with a higher-addition bifocal intraocular lense in the fellow-eye might be a promising approach to address these drawbacks of current binocular and trifocal intraocular lenses.
