Tecnis® Multifocal and Symfony Intraocular Lens Implants (IOLs) for Refractive Lens Exchange and Cataract Surgery in Dayton Ohio

About The Tecnis® Multifocal and Symfony Lens Implant

When we were younger our eye focused up close naturally, something called accommodation.  As we age past our mid-forties we lose enough of that ability, and we start wearing reading glasses.  To restore some of that ability to see upclose, the Tecnis® Multifocal and Symfony Lenses use diffractive optics to split the incoming light into focal points for distance and near.  By incorporating the diffractive optics across the entire lens, the Tecnis can work in dim light conditions as well as bright.  And by incorporating correction for spherical aberration, the Tecnis maintains better night vision.  Unlike accommodating lenses like the Crystalens, all multifocal lenses (Tecnis, Symfony, and ReSTOR), have some compromise to night vision and distance vision with slight glare and halos.  This is inherent in the design, as they split the incoming light. This night glare tends to diminish over time.  Tecnis and Symfony Multifocal lenses come in several strengths that allows your doctor to customize your vision to the distance you use most for near and enable you to read smaller print sizes.


How the Tecnis® Multifocal and Symfony Implant Lens Works
The Tecnis® Multifocal and Symfony (pronounced "symphony") Implant Lenses work by splitting the light reaching the eye into two focal points, providing good vision at near and far.  The Tecnis Multifocal uses diffractive optics spread over the entire lens surface, and works well in dim and bright light conditions.  While the optical qualities of these lens allows patients to see distance and near, some intermediate distances may be a little out of focus.  Along with the ReSTOR, this lens has some night glare and halos around lights.  This night glare is very noticeable at first, but improves over time. Tecnis Multifocal lenses come in several strengths that allows your doctor to customize your vision to the distance you are most comfortable reading.  The Symfony implant lens (said symphony implant lens) is an improved design of the Tecnis multifocal lens with somewhat improved intermediate vision.  The Symfony lens is the first FDA approved multifocal lens that can correct for astigmatism as well!  Now more patients are candidates for bifocal implant lenses, especially if they have astigmatism.

Strengths: You can see to drive and play sports, as well read. Laptops, cell phones, Kindles, paper back books, needle point, newspaper, etc… are all in clear view.
Weaknesses: Some glare/halos and loss of contrast with night driving that improves over time, slightly less clear intermediate (music stand, some desktop computers).


Imagine being able to see your world as well as you did when you were younger, without the help of glasses and contacts, or reading glasses. The best way to determine if the Tecnis® Multifocal or Symfony Implant is the best choice for you is by coming in for a complete eye exam.  Once our eye surgeons, Drs. Stahl and Knowles, have measured and examined your eyes, we can discuss your lifestyle and near vision needs and discuss which procedure will help you see your best.
