What is Implantable Contact Lens (ICL)?

Evolution in Visual Freedom

Over 99% achieve driving vision or better

Whilst you may have heard it called an Implantable Contact Lens (ICL), the EVO Visian ICL is officially called an Implantable Collamer Lens. It is an excellent alternative to Laser Eye Surgery for patients who are not ideal candidates (those who suffer from dry eyes, thin corneas or have very high prescriptions).

Think of it as a micro thin contact lens that is placed inside the eye, rather than on the surface of the eye. It is made of Collamer (over 1 million collamer lenses have been implanted to date), which is a technologically advanced lens material that because of its collagen base, is 100% biocompatible and designed to function in harmony with your natural eye. There is no rejection by the human body.

The EVO Visian ICL has been approved in Europe since 1997 and FDA approved in the US since 2005. In that time, over 700,000 eyes have been implanted with EVO Visian ICLs and there has been a proven safety record with a patient satisfaction rate of 99%.

The US military have approved EVO Visian ICL for their personnel and have been monitoring the results. They concluded EVO Visian ICL provides “excellent visual and refractive results”. The study showed excellent vision quality and stability of the lens inside the eye even in combat. Here at AVC we pride ourselves on having successfully treated a large range of prescriptions ranging from -20D of short sightedness to +8D of longsightedness as well as 6D of astigmatism.

AVC is the first clinic to implant a hyperopic astigmatic ICL in UK and that too for a doctor. AVC is the first clinic to treat very high myope (short-sightedness) of -23D.

EVO is an Evolution in Visual Freedom designed to provide premium refractive outcomes while optimizing patient comfort.

Benefits of EVO Visian ICL

  • Does not induce dry eye syndrome
  • Sharp, Clear Vision
  • Excellent Night Vision
  • Great for those with thin corneas
  • UV protection built into the biocompatible lenses
  • A typically quick, 20-30 minute or less procedure and most people are able to resume daily activities in just a few short days with clearer vision
  • Treats a wide range of prescriptions: myopia (short-sightedness), hyperopia (long-sightedness) and astigmatism.
  • One ICL implanted every 8 minutes worldwide.
  • ICL is invisible, undetectable and does not change the colour of the eye.

Removability for your peace of mind

The advantage of the Visian ICL is that it can permanently correct your vision, yet no natural tissue is removed in any way during the procedure. If for the unlikely reason you need or wish to remove your Visian ICLs in the future, your doctor can accommodate you.

In harmony with your natural eye

For people who value health and wellness the Visian ICL could be the choice for you. The Collamer base of the lens material is biocompatible, meaning it is designed to function in harmony with your natural eye.

What is Visian ICL?

There are a few different types of ICL treatments and AVC are the pioneers of Visian ICL, which is the most advanced form of ICL treatment.

Unlike other types of ICL, Visian ICL is FDA approved and has a proven safety record. With Visian ICL, the lens is inserted in the anterior chamber instead of being iris-fixated or supported in front of the iris like other types of ICL.

This positioning of the lens means that the lens cannot be seen and eliminates the risk of scarring and endothelial cell loss, making it the safest and convenient type of ICL treatment.
