It is, to my knowledge, the first three-dimensional bag-filling IOL.
Since light is not divided into multiple foci, Synchrony yields contrast sensitivity curves comparable to those of monofocal IOLs.
In order to achieve that goal, dual-optic accommodating Intraocular Lenses have been designed, whose anterior optic displaces axially to increase ocular power, and focus near objects.
Although dual-optic accommodating IOLs are relatively new, their outcomes are promising, as they provide large amplitudes of accommodation and a greater IOL displacement than single-optic accommodating IOLs.
Defocus curves in the accommodating IOL group were compared with those in the control group.

To evaluate the clinical outcomes of an accommodating dual-optic intraocular lens (IOL). A prospective noncomparative case series with retrospective control comprised 21 patients (26 eyes) scheduled for small-incision extracapsular cataract extraction by phacoemulsification with implantation of the Synchrony dual-optic accommodating IOL (Visiogen) (accommodating IOL group) and 10 patients who had small-incision extracapsular phacoemulsification with implantation of a monofocal, single-optic IOL at least 6 months previously (control group).
Patients were examined 1, 3, 6, and 12 months after surgery.
Accommodating IOLs hold the promise of providing good distance, intermediate, and near acuity with fewer optical aberrations than currently available multifocal IOLs.
Dual-optic accommodating IOLs provide greater accommodative amplitudes than single-optic accommodative lenses but are also slightly more challenging to implant.
Como consecuencia, disminuye la capacidad de acomodación, lo que dificulta el enfoque de los objetos cercanos.
