Visual Acuity After the Combined Binocular Implantation of +2.0 Diopters and +3.0 Diopters Oculentis Multifocal Intraocular Lenses.
June 28, 2017 updated by: PD Dr. med. Eckart Bertelmann
Evaluation of the Visual Acuity After the Implantation of an Oculentis +2.0 Diopters (Torical) Bifocal Intraocular Lens (MplusX (Toric) LU-313 MF20T/LS-313 MF20) in the Distance Dominant Eye, in Combination With a +3.0 Diopters Oculentis Bifocal Intraocular Lens (MplusX (Toric) LU-313 MF30T/LS-313 MF30) in the Fellow Eye.
The objective of this study is to assess the visual outcome after the combined binocular implantation of +2.0 D and +3.0 D refractive multifocal intraocular lenses.
Study Overview

Conditions
Detailed Description
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.
