The TECNIS Symfony Lens is an FDA-approved intraocular lens or IOL, which is the first and only lens with extended depth of focus for people suffering from cataracts. It was approved by the U.s Food and Drugs Administration in 2016 for use with laser cataract surgery.
These TECNIS Symfony IOLs are the only lens available in the U.S which can provide patients a full range high-quality vision after their cataract surgery. Apart from its ability to provide enhanced vision for cataract patients, it can also help people with presbyopia by improving their ability to focus on objects which are near. There is also a version of the lens known as Tecnis Symfony Toric IOL, which is meant exclusively for people suffering from astigmatism.
What makes the Tecnis Symfony Lens so unique is that it can diffract light in such a way that the patient can have an extended range of focus, which the surgeon can set for distance, medium or near vision. Instead of producing two focal points, the goal here is to elongate the focus of the eyes, thereby allowing for a more continuous spectrum of clear and sharp vision whether from a distant, medium or near point.
What advantages does the TECNIS Symfony Lens offer?
Unlike traditional IOLs, the TECNIS Symfony Lens are designed keeping in mind the specific goal of improving both the quality as well as rage of vision. Usually, with traditional monofocal lenses, the patient will be able to see distant objects, but near objects are out of focus. Experts have been trying to find a solution to this bothersome issue for years, and it seems like the TECNIS Symfony Lens is the solution they have been looking for.
When there is no blurry vision zone between two focal points, it brings about a number of advantages. As mentioned before, there is reduced haloes and glares. On top of this, the post-operative movement of the IOL does not affect the extended depth of focus.
However, perhaps the most important benefit of the TECNIS Symfony Lens is that it is available in toric form as well, which means that patients living with astigmatism can now have sharp and focused vision for both near and distant objects.
In short, the TECNIS Symfony Lens is able to provide sharp, high-quality vision seamlessly during day and night for both near and distant objects, and also allows patients to experience lower incidences of glares and haloes.
