Finevision, the first Intraocular Lens with trifocal diffractive optic.
The Finevision IOL optic combines two diffractive structures which are adjusted to offer additions of +3.5 dioptres (for near vision) and +1.75 dioptres (for intermediate vision) respectively. It is designed to reduce the loss of light energy from the image associated to any diffractive system. This optimisation results in significantly improved intermediate vision, whilst maintaining quality in near vision.
Multifocal: Optimising Distant, Intermediate and Near vision.
Thanks to its design which has been studied in-depth, Finevision has an anterior surface with a sophisticated variation of heights of the diffractive steps. This enables light distribution on distant, intermediate and near focal points to be in accordance with the opening of the pupil.
Consistent visual results
The results obtained in patients with Finevision lenses are consistent with all the preliminary tests performed in laboratories, obtaining a high degree of satisfaction with visual acuities (without correction) obtained at all distances and an extended visual field in all light conditions.
