The new so-called TECNIS Symfony lens has been available since September 2014. This multifocal implant lens is a great help for many patients so that they no longer have to wear reading glasses and can see clearly again at all distances. The plastic implant lens is British made and lasts a lifetime. The Symfony lens has the potential to help a large number of patients, and offers enormous benefits. This revolutionary implant lens mimics the natural lens. This implies that refractive surgeons and patients are very happy with the lens.

Target group Symfony lens: Patients with presbyopia, cataracts or reading problems
Patients suffering from presbyopia (medical term is “presbyopia”) or cataracts as well as patients with reading difficulties are suitable candidates for the Symfony lens. There is good news for patients who need to undergo cataract surgery.
Each eye contains a small lens. In a young, normal eye, this lens is clear and elastic. The lens hardens with age. As a result, patients no longer see well up close. Presbyopia starts around the age of 40. The first symptom is usually that patients experience reading problems, for example. For these patients, bifocal or varifocal glasses are necessary for clear vision at all distances.
As the natural lens in the eye continues to age, the lens begins to cloud over and take on a brown color, causing patients to experience blurred or blurred vision (blurred vision). Colors then also lose their shine. In the beginning, different glasses may help, but untreated cataracts often lead to blindness. More than 60% of patients over the age of 60 suffer from cataracts. If everyone lives long enough, they will almost always have to deal with this eye condition.
Available treatments for these eye conditions
- Femtosecond Laser – Cataract Surgery
- Lightweight adjustable lens
- Multifocal lens
- Symfony lens
- Trifocal lens
Some patients opt for laser treatment that adjusts the shape of the eye. However, if the lens continues to harden, the effect of this treatment only lasts a few years. The plastic material of the Symfony lens does not change, meaning the lens will last a lifetime.
Advantages and disadvantages of multifocal implant lens in patients
Doctors from both Belgian and Dutch eye laser clinics use the Symfony lens. The lens offers many advantages, but also a disadvantage.
Advantages
The Symfony lens is a revolutionary new British-made implant lens. The lens offers many advantages that have been supported by a clinical study conducted in New Zealand.
- Better results : Sharp vision for all distances, far, near and also in between: Perfect, stepless transition from close to far viewing. 100% of patients no longer use glasses for distance or near vision, and 94% of patients no longer require glasses for intermediate vision.
- Contrast : There is no reduction in contrast sensitivity.
- Halo : Patients experience little or no halos or glare (glaring light) unlike traditional multifocal lenses.
- Short operating time : First the ophthalmologist makes an incision of 3 mm. He then removes the natural lens and finally inserts the plastic implant lens. All this takes just a few minutes.
- Color vision : Thanks to this lens, more light comes in, making it easier for patients to distinguish colors.
- Reading glasses : As many as 9 out of 10 patients no longer need reading glasses after surgery with an intraocular Symfony lens after clinical studies.
- Longevity : Dr. Bobby Quereshi of the London Eye Hospital claims that the lens will last a lifetime as it is made of plastic.
- Fewer side effects : No lens-related side effects were noted because the surface of the lens is ground differently (echelette design).
- Night vision : Thanks to the lens, driving the car at night is possible again. In other words, night blindness is a thing of the past thanks to the Symfony lens.
- Fast recovery : The patient’s vision is clear again a few days after the operation. In addition, vision recovers very quickly as most patients can resume their daily activities within 24 hours after the operation.
Cons
The price is a possible disadvantage. The Symfony lens is quite expensive and costs several thousand euros.
