What Is ICL Surgery?

The EVO ICL, also known as the Implantable Collamer® Lens, is a type of refractive procedure to help correct common visual problems. Biocompatible collagen copolymer material called Collamer® works in harmony with the eye. The intracameral lens, which is slightly smaller than a typical contact lens, is implanted in the eye during a 20 to 30-minute procedure. Unlike laser vision correction surgeries that permanently change the shape of your cornea, the EVO ICL procedure is additive, meaning that no corneal tissue is removed. During the ICL procedure, Dr. Kraff inserts a biocompatible synthetic lens into the eye. The EVO ICL lens sits between the iris (the colored part of the eye) and your natural crystalline lens.

The ICL permanent contact lens has a prescription, which is calculated beforehand by Dr. Kraff. Each prescription is specific to each individual and their specific visual needs. This surgical procedure improves vision without altering the cornea; we don't remove any tissue from the cornea as we do with PRK. For some patients, this is a viable option when they don't qualify for a laser vision correction procedure.

Implantable Collamer Lens Procedure

Vision correction with the EVO ICL is an outpatient procedure that typically takes 20 to 30 minutes. An EVO ICL procedure is performed one eye at a time, with the second eye being treated a couple of weeks after the first. On the day of the procedure, your eyes will be numbed with an anesthetic eye drop and your refractive surgeon will implant the ICL between the iris (colored part of the eye) and the natural lens.

Visian ICL Recovery & Results

Following surgery, a short recovery period is expected. Our team will provide detailed instructions on post-procedure care to ensure a smooth healing process. Many patients resume their normal activities within a couple of days following the procedure.

After surgery, patients can experience significant improvements in their vision, with reduced dependency on glasses or contact lenses. Although results may vary, many individuals achieve excellent visual results.

People who want a flexible and organic vision correction option, as well as patients who are not candidates for laser vision correction, find that EVO ICL is the right procedure for them.

Can the EVO ICL Lens be removed?

Expand F.A.Q.

Yes, the EVO ICL is intended to provide permanent vision correction, but it can be removed or upgraded by your surgeon if necessary.

Will I be able to feel the EVO ICL Lens?

Expand F.A.Q.

No, patients shouldn't feel the lens as it doesn't adhere to any structures within the eye and doesn't move once in place.

Will other people be able to see the ICL lens?

Expand F.A.Q.

No, the EVO lens is placed behind your iris where only your eye doctor will be able to detect it.

Are there any risks with the ICL procedure?

Expand F.A.Q.

Any medical procedure has the potential for risk associated with it. Possible complications of the EVO ICL procedure, although rare, include inflammation, an increase in eye pressure, or the need for an additional procedure, like an ICL exchange. You should NOT have EVO ICL surgery if your doctor determines that:

1) The shape of your eye is not appropriate.

2) You don't meet the minimum endothelial cell density for your age at the time of implantation.

3) You have moderate to severe glaucoma.

4) Your vision isn't stable; or 5) if you're pregnant or nursing. While these potential risks are mitigated as much as possible, they can all typically be addressed early and without long-term side effects.

Does ICL surgery hurt?

Expand F.A.Q.

During ICL surgery, local anesthesia is used to numb the eye, ensuring a painless experience. Patients typically report minimal discomfort or pressure sensations, but no pain during the procedure.

What is the difference between EVO ICL vs. LASIK?

Expand F.A.Q.

The main difference between EVO ICL and LASIK is the approach to the vision correction procedures. While LASIK involves reshaping the cornea using a laser, EVO ICL is an implantable lens that's inserted into the eye, making it a reversible procedure with potentially fewer side effects.
