Improve Your Vision With EVO ICL

EVO ICL, also known as Implantable Collamer® Lens, is a refractive implant to correct common vision issues like myopia (nearsightedness) and astigmatism. Unlike other vision correction options, the EVO ICL is an additive technology that improves vision without removing any corneal tissue. It is a 20 to 30-minute same-day procedure that is painless. You can expect clear night and day vision. It is permanent but removable.

The Implantable Collamer Lens for nearsightedness is a refractive lens also known as a phakic IOL. “Phakic” meaning that the natural lens of the eye remains in place, and “IOL” meaning intraocular lens, or a lens inside the eye. The Visian ICL is a posterior chamber implant that is inserted through a small incision in the eye behind the iris, and in front of the natural crystalline lens to correct your nearsightedness.

The ICL (Implantable Collamer Lens) is a specialized treatment aimed at addressing moderate-to-high levels of nearsightedness and astigmatism. It offers an alternative solution to other refractive surgeries like LASIK, SMILE, and PRK.

Unlike procedures that involve reshaping the corneal surface, the ICL procedure is particularly suitable for individuals with irregular corneas or those who cannot undergo laser eye surgery. It's also an option for patients with astigmatism and severe nearsightedness beyond the range that can be treated with LASIK. However, it's important to note that the eligibility for and interest in ICL is not restricted solely to individuals with irregular or thin corneas.

An advantage of the ICL is its ability to provide exceptional visual clarity. It offers precise outcomes, surpassing other vision correction procedures. Furthermore, the reversibility of the ICL procedure makes it appealing to many patients who simply desire remarkably sharp and clear vision. Additionally, individuals with visually demanding professions or hobbies often find the ICL to be a popular choice.

While complications are rare, ICL can carry potential risks. You should not have ICL if:

  • Your doctor determines that the shape of your eye is not an appropriate fit for ICL
  • You are pregnant or nursing
  • You do not meet the minimum endothelial cell density for your age at the time of the implantation

The best determine if you're a candidate is to request a free screening. 

Yes. The  ICL is intended to remain in place without maintenance. However, the ICL can be removed if needed.


No. The ICL is positioned behind the iris, where it is invisible to both you and others. Only an eye doctor will be able to tell that you have had an ICL vision correction procedure.


ICL is not noticeable after it is implanted. It does not attach to any structures within the eye and does not move around.

ICL surgery is performed on an outpatient basis which means the patient has surgery and leaves the same day. The procedure itself usually takes 20 minutes or less. You will need someone to drive you home on surgery day.

The ICL is carefully inserted into the eye, where it bends the light to focus it perfectly onto the retina, much like a contact lens does on the eye's surface. Unlike regular contact lenses, the ICL is composed of biocompatible material and is positioned inside the eye, specifically between the iris (the colored part of the eye) and the natural lens. Once in place, it remains there indefinitely without requiring maintenance, although it can be removed if needed in the future.

Because the ICL is situated between the iris and the natural lens, it is completely invisible to both the patient and onlookers. The procedure itself is swift and painless, typically lasting only 10 to 20 minutes.

Beyond its vision correction capabilities, the ICL also acts as a protective barrier against harmful UV rays. The collamer material used in ICLs possesses distinctive properties that offer UV protection while maintaining the passage of natural visible light, resulting in sharp and precise vision.

LASIK is a procedure that uses a laser to change the shape of the surface of the eye. The ICL does not change the shape of the eye. The ICL is implanted inside the eye and works alongside the natural structures of the eye to achieve clear vision without glasses or contact lenses.


No. Patients who get dry eyes from traditional contact lenses may be ideally suited for ICL since you cannot feel this lens. ICL is designed to remain in place and inside your eye, without maintenance. After the ICL is implanted, a routine, annual visit with your eye doctor is recommended, just as it is for all people to maintain eye health.
