Implantable Contact Lens™


Wish you could do away with your glasses?
What's an option that has good short and long term outcomes?
Beyond LASIK, comes the EVO Visian Implantable Contact Lens

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

diagram of the human eyeEvery 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.

Advantages of Visian ICL™ vs LASIK

1. Long term stable vision

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

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.

The first Visian ICL™ was successfully implanted in 1998 in Europe. Now, Visian ICL™ in Singapore is available through The EyeClinic.

Worldwide, over 1,000,000 lenses have been implanted since then. The procedure is taking off very rapidly now, because of its excellent long-term results both in terms of efficiency and safety.

Have you been turned away from LASIK or PRK because the doctor diagnosed you with keratoconus? Well that does not mean that you can never be free of contacts or glasses. You may still be suitable for Visian Implantable Contact Lens (Visian ICL™), a reversible vision correction option that keeps your cornea pristine.

A) Surgeon's experience with EVO Visian ICL™ and short-sightedness

Dr Lee is on the expert training panel to other surgeons internationally and locally for the EVO Visian ICL™. As a result of her experience in terms of years of experience and surgical numbers, you will have a smoother pre-operative and surgical journey and more predictable results. She also specialises in diseases related to short-sightedness. If you cannot see without glasses you are probably short-sighted. Short sighted patients have higher risk of floaters and retinal problems.

Who is suitable for Visian ICL™?
1. Anyone who needs glasses to see better, including post-LASIK patients

2. Anyone who has sufficient anterior chamber depth within the eye. This is measured by a rapid, non-contact and painless scan at our clinic and the results will be derived immediately.

What is the downtime?
The surgery takes about 10 minutes and we expect you to see well enough to watch TV and read on your iPad on the same day.

What are the risks of Visian ICL™?
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.

What is involved in the Visian ICL™ procedure?
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.

What if my vision changes?
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.

Does the Visian ICLTM dry out or get dirty like a contact lens?
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.

Can the Visian ICLTM be seen by the naked 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.

Can I feel the Visian ICL?

How long can the Visian ICLTM stay in the eye?
The Visian ICL™ is intended to remain in place indefinitely

LASIK Surgery and Alternative Eye Treatments

Laser-assisted in situ keratomileusis, more commonly known as LASIK, laser eye surgery, or laser vision correction, has boomed in popularity across the globe in recent years.

LASIK surgery in Singapore and other parts of the world is seen as a permanent alternative to eyeglasses or contact lenses.
