TECNIS® Symfony IOL is the first and only presbyopia-correcting extended range of vision IOL. It delivers a continuous full range of high quality vision with reduced incidence of halos and glare comparable to a multifocal IOL.
The Symfony lens, which treats presbyopia (age-related long-sightedness) is implanted into the eye during a normal cataract operation. In most cases recovery time is minimal, with patients able to return to their usual routine just 24 hours after surgery. Unlike traditional multifocal lenses, there are no glares or halos with the Symfony lens, no reduction in contrast sensitivity, and it has a special defraction grating, making it similar to a traditional lens implant but with the added benefit of a reading prescription. A clinical study, carried out in New Zealand, discovered:
- Compared to previous monofocal lenses, there is no compromise in distance vision with the Symfony lens
- 100% of patients used for the study no longer need distance spectacles, with 94% no longer requiring spectacles for intermediate vision
- There were no reports of ‘glare’ or ‘halo’
- There were no reports of lens-related adverse effects
Significant Increased Range of Vision with Halo and Glare Comparable to a Multifocal IOL
TECNIS® Symfony IOL delivers:
- Sustained mean visual acuity of 20/20 or better through 1.5 D of defocus
- Full range of functional (20/40 or better) vision through 2.5 D of defocus
- Incidence of halo and glare comparable to a multifocal IOL
Near and Intermediate Visual Acuity Improvement over Monofocal IOL
TECNIS® Symfony IOL subjects demonstrated:
- 20/20 or better mean distance and intermediate visual acuity
- A 2-line improvement in mean intermediate and near visual acuity
At three months, TECNIS® Symfony IOL subjects experienced high spectacle independence at far, intermediate, and near distances. At three months, there were no spontaneous reports of glare or halo.
