The Intraocular Tecnis® Symfony Lens is the first and only intraocular lens with augmented depth of field, used together with cataract surgery or phacorefractive to corect myopia, astigmatism, ipermetropia and presbyopia.
This is a new technology developed in the optic lab by Professor Pablo Artal, with whom Dr. Badalà collaborates since 2008. This intraocular lens offers a wide, high definition, vision spectrum, with reduced incidence of collateral effects such as glare and halos around light sources, compared to traditional multifocal lenses.
Dr. Badalà has been the first to use the Intraocular Toric Symfony Lens in Milan in order to correct myopia, astigmatism and presbyopia, in september 2014.
The Symfony Intraocular Lens is implanted in the eye during a common cataract surgery. In the majority of cases, recovery time is minimum and patients are able to perform everyday activities 24h later. The main difference between traditional multifocal lenses, is that halos around light sources are reduced to a minimum and there is no reduction in the perception of contrast; the lens offers a special diffractive profile that makes it similar to a monofocal lens, but with the added capability of properly reading focusing on near objects.
A clinic study from New Zealand proved that:
Focusing on far object with the Symfony Intraocular lens is comparable to eyesight with traditional monofocal lenses.
100% of patients in this study, had no need to use glasses to focus on far objects. 94% had no need for glasses to focus on medium distance objects (e.g. computer, car dashboard, etc.).
No risk of halos around light sources or dazzle.
No record of negative effects connected to the lens usage.
The intraocularTECNIS® Symfony Lens increases depth of field granting:
An average visual acuity of 10/10 or more, with a depth of field od 1.5 diopters.
A range of functional vision (5/10 or better) and a depth of field of 2.5 diopters.
The incidence of halos and dazzle is comparable to the one registered with a monofocal intraocular lens.
Focusing on near and mid-distance objects is better than monofocal IOL.
Patients using the TECNIS® Symfony IOL proved:
Average visual acuity for far and mid-distance vision of 10/10 or more.
A visual acuity improvement for near and mid-distance vision of 2 lines at least.
Patients using IOL TECNIS® Symfony reported a high level of indipendence from glasses for far, mid-distance and near vision.
3 months after the surgery thare have been no spontaneous reports of halos around light sources or dazzle phenomena.
