What is EVO Visian Implantable Collamer Lens™?

“It works like your normal contact lens but without the daily hassle and discomfort”

ICL is a specialty customised lens placed in your eye which works with your natural lens to correct your vision. It’s been termed BEYOND LASIK because unlike LASIK there is no corneal destruction and is thus reversible. This means less or even none of the short and Long term side effects of LASIK.

Inplanting lens between the natural lens and the iris
Every few years, a ground breaking procedure becomes available. There was PRK followed by LASIK and now there is the EVO Visian Implantable Contact Lens ( EVO Visian ICL™) from Switzerland. This is a revolutionary advancement as it is reversible and causes no damage to your natural eye.

Why Choose ICL™?

Advantages of Visian ICL™ vs LASIK

Long term stable vision

As the cornea is not artificially thinned like LASIK, the prescription remains stable.

No need for glasses when presbyopia develops

This is because the Visian ICL™ is reversible. Hence, when presbyopia sets in, it can be exchanged for a multifocal lens. This is not an option for most LASIK patients with thinned cornea. 

No dry eyes

The nerves within the cornea which stimulate tear production are also cut in LASIK. This is why post-LASIK patients suffer from dry eyes. The nerves are left intact in Visian ICL™ so dry eyes are not a concern. This means more comfort, no red eyes and better vision. 

Why do we save the cornea
  1. For better quality of vision now and in the future No dry eyes
  2. No need for reading glasses as you can have multifocal lenses in future
  3. Accurate calculation for cataract surgery when needed in older age

For many, Visian ICL™ not just a cosmetic procedure. It is an optical fact that the nearer a vision correction is placed nearer to the sweet spot (nodal point) in the eye, the clearer the vision. This explains why glasses give poorer vision than contact lenses. But with contact lenses, dry eyes and irritation (especially with prolonged wear) causes your eyes to look tired and red. The added advantage of the Visian ICL™ is that even those who were previously turned away from LASIK, such as those with thin corneas, chronic dry eyes, or extreme refractive error, now have hope. Moreover, by protecting the windscreen of the eyes (the cornea), the quality of vision stays crisp and patients will still be able to maintain his High Definition (HD) vision.


Visian ICL™ procedure is reversible so that in future, should vision problems occur due to ageing, there are still options available to treat the issue. Visian ICL™ also has UV protection which offers added coverage against the harmful sun rays that can cause retinal problems.

Who is suitable for ICL™?

The basic criteria of Visian ICL™ is that there should be enough space for the lens to be placed. This is easily determined by a quick, non-contact scan where the results are known immediately.
We have enormous technical and surgical experience with EVO ICL tm. So you can trust us to be confident of your assessment of suitability as this can differ from clinic to clinic. 
Good news for those who failed a  LASIK assessment eg candidates who were turned away due to dry eyes, severe myopia or a thin cornea . You are suitable for EVO  Visian ICL™ too.
After 20 years history, the Visian ICL™ is FDA approved and can correct:
  1. Myopia up to 1900 degrees
  2. Long sightedness up to 1000 degrees
  3. Astigmatism up to 600 degrees

Additionally, there should not be any changes to one’s glasses prescription of more than 50 degrees in a year and patients seeking to undergo the Visian ICL™ procedure should not be pregnant. Non-LASIK candidates who were turned away due to dry eyes, severe myopia or a thin cornea can opt for Visian ICL™ as well.


These are our suggestions:

  • We expect you to see well enough to watch TV and read on your phone on the same day and you leave with no eye shield just sunglasses. Your eyes feel pretty comfortable after.
  • No water and contact sports for 2 weeks.
  • No facials and eye lash extension for 2 weeks.
  • You could go back to work after 2 days
  • Air travel after two days

Though very rare, one of the risks of Visian ICL™ is infection (0.01%). The other risks related with Visian ICL™ are largely preventable if an ultrasound is used. The EyeClinic has 2 ultrasound machines to ensure that your Visian ICL™ size is customised for your eyes. The risk of cataracts which can happen if the Visian ICL™ is too small or glaucoma if the Visian ICL™ is too big are largely eliminated.

Detailed measurement of the anterior segment of the eye is taken

So we arrive at this desired result.

The procedure takes about 5 minutes in each eye. The surgery can be performed under local anaesthesia (with the use of eye drops) or general anaesthesia which is pleasant if you prefer not to be aware of the surgery. There is therefore very little discomfort and normally no pain associated with the procedure.

If there are major changes in your vision, the Visian ICLTM can be easily removed and replaced. The Visian ICLTM does not replace reading glasses when presbyopia sets in. However, when presbyopia sets in, we can exchange the Visian ICLTM for a lens that allows you to see both far and near. The reversibility of the Visian ICLTM is its unique selling point. That is unlike LASIK, where your future options for the eye become limited once the cornea is thinned.

No. The Visian ICL™ is designed to remain in place within the eye without maintenance. You can dive, fly and sleep without worries with the ICL™. Normal contact lenses that lie ON the eye cause dry eyes and irritation after prolonged wearing hours. This will not happen with Visian ICL as it is WITHIN the eye.

No. Because the Visian ICL™ is placed behind the iris, neither you, nor an observer will be able to see the lens. It has no colour.

The EVO ICL™ is intended to remain in your eye as long as you want it to. Unlike regular contact lenses, there is no need to remove it to wash nor is there an expiry date.
