EVO ICL® in Chicagoland
EVO ICL® (Implantable Collamer® Lens) is an advanced vision correction option available at Kovach Eye Institute across Chicagoland, including Naperville, Elmhurst, Lincolnwood, and South Barrington. If you’ve been told you’re not a candidate for LASIK or SMILE, or if you’re seeking a reversible alternative to traditional refractive surgery, EVO ICL may be the solution you’ve been looking for. Our experienced surgical team specializes in this innovative procedure, offering patients the opportunity to achieve enhanced vision without corneal reshaping.
At Kovach Eye we believe in vision without limits.

What Is EVO ICL?
EVO ICL is a thin, biocompatible lens made of Collamer material that is surgically placed inside your eye, positioned between your natural lens and the iris. Unlike LASIK, which permanently reshapes the cornea, the EVO ICL does not remove any corneal tissue and is reversible, meaning it can be removed or replaced if needed in the future.
The procedure is FDA-approved and designed to correct myopia (nearsightedness) and astigmatism. The entire surgical process takes approximately 15 minutes per eye and is performed as an outpatient procedure.
How EVO ICL Works
During your EVO ICL procedure, your surgeon creates a small incision in the cornea and gently inserts the folded lens into the eye. Once positioned, the lens unfolds and settles into place behind the iris. The lens works by bending light rays as they enter the eye, correcting refractive errors and allowing light to focus properly on the retina.
Because the lens is placed inside the eye rather than on the corneal

methods.
The procedure preserves corneal tissue, which is particularly beneficial for patients with thin corneas or high prescriptions.
Benefits of EVO ICL
Reversibility: Unlike LASIK or PRK, EVO ICL can be removed or exchanged if your vision needs change over time.
Biocompatibility: The Collamer material is designed to be well-tolerated by the eye, with a low risk of rejection or inflammation.
Minimal Corneal Impact: Because the procedure does not reshape the cornea, it’s an excellent option for patients with thin corneas or those who want to preserve corneal tissue.
High Prescription Correction: EVO ICL effectively corrects moderate to high myopia and astigmatism, often providing results for patients who don’t qualify for LASIK.
Fast Visual Recovery: Many patients experience improved vision within days, with continued improvement over the following weeks.
Enhanced Night Vision: The EVO ICL’s design minimizes halos and

concerns.
Long-Term Stability: The lens remains stable within the eye and does not require ongoing maintenance or replacement under normal circumstances.
EVO ICL vs. LASIK: Key Differences
While both procedures correct refractive errors, they work in fundamentally different ways. LASIK uses an excimer laser to reshape the cornea, whereas EVO ICL places a lens inside the eye. This distinction makes EVO ICL ideal for patients with:
- High myopia or astigmatism
- Thin corneas
- Dry eye concerns
- A desire for reversibility
LASIK may be appropriate for patients with lower prescriptions and thicker corneas. During your consultation, our surgeons will evaluate your individual eye anatomy and vision goals to recommend the best option for you.
Am I a Candidate for EVO ICL?
EVO ICL is suitable for patients aged 21 to 45 with stable vision prescriptions. Ideal candidates typically have:
- Myopia ranging from -3.00 to -20.00 diopters
- Astigmatism up to 4.00 diopters
- Healthy corneas and retinas
- No active eye disease or infection
- Realistic expectations about surgical outcomes
During your comprehensive consultation, our surgeons will perform detailed eye measurements and assessments to determine your candidacy. Some patients may not be suitable candidates due to factors such as keratoconus, severe dry eye, or certain retinal conditions. A thorough evaluation ensures your safety and optimal results.
The EVO ICL Procedure: What to Expect
Before Surgery
You’ll attend a pre-operative appointment where we’ll perform advanced imaging and measurements of your eye. You’ll receive detailed instructions on how to prepare, including guidelines about contact lens wear, medications, and what to bring on surgery day.
Day of Surgery
Arrive early for final checks and to receive numbing eye drops. You’ll be positioned comfortably under the surgical microscope. Your surgeon will create a small incision, insert the folded lens, and position it carefully. The entire procedure takes about 15 minutes per eye.
After Surgery
You’ll rest briefly in our recovery area before being discharged. You must arrange for someone to drive you home. Your vision may be blurry initially, but this typically improves within 24 to 48 hours. You’ll use prescribed eye drops and follow post-operative care instructions carefully.
Recovery and Results
Most patients notice improved vision within the first few days following EVO ICL surgery. However, vision continues to stabilize over the following weeks as your eye adjusts to the lens. Full visual stability is typically achieved within one to three months.
During your recovery period, you’ll attend scheduled follow-up appointments at one day, one week, one month, and three months post-surgery. These visits allow our surgeons to monitor your healing and ensure optimal lens positioning and visual outcomes.
You should avoid strenuous activities, swimming, and contact sports for at least one week. Most patients return to normal daily activities, including work, within a few days. Your surgeon will provide specific guidelines based on your individual healing progress.

I am now six months post ICL surgery and I couldn't be happier with how Kovach took care of me. My cornea was too thin for Lasik and I've been wearing contacts for 35 years. With vision around -5.00 for each eye and some stigmatism, I was not going to be an easy patient. Seeing 20/20 still! Highly recommend considering ICL and Kovach for your eye surgery. - Brian O.
Dr. Kovach was great. He explained everything in the office and during the surgery. His staff at the office and surgical center were pleasant and thorough. A very pleasant and successful experience. Absolutely no complaints. - Mark N.
I had the ICL surgery to correct my vision. Before surgery, my vision was -11, the next morning I had 20/20 vision. I recommend Dr. Kovach to anyone who might be considering this surgery, he did a great job and really cares about his patients. - Natalia C.
Frequently Asked Questions About EVO ICL
The surgical procedure itself takes approximately 15 minutes per eye. However, you should plan to spend 1 to 2 hours at our facility for pre-operative preparation and post-operative monitoring.
No. Your eyes will be numbed with anesthetic drops before surgery, so you won’t feel pain during the procedure. You may feel mild pressure or slight sensations, but discomfort is minimal.
Many patients notice improved vision within 24 to 48 hours. Vision continues to improve and stabilize over the following weeks and months as your eye adjusts to the lens.
Yes. One of the key advantages of EVO ICL is its reversibility. The lens can be removed or exchanged if needed, though this is rarely necessary.

with the majority of patients achieving their target vision correction. During your consultation, we’ll discuss realistic expectations based on your individual prescription and eye anatomy.
You should avoid strenuous activities, swimming, and contact sports for at least one week. Most patients return to normal activities within a few days. Your surgeon will provide specific guidelines during your post-operative visits.
The lens is designed to remain stable within the eye indefinitely. It does not require replacement or ongoing maintenance under normal circumstances.
Most patients achieve excellent vision without glasses or contact lenses. However, some patients may need reading glasses as they age, particularly after age 40, due to presbyopia (age-related loss of focusing ability). This is a natural part of aging and is not specific to EVO ICL.
As with any surgical procedure, EVO ICL carries some risks, including infection, inflammation, or lens malposition. However, serious complications are rare when the procedure is performed by an experienced surgeon. During your consultation, we’ll discuss all potential risks and how we minimize them.
Pricing varies based on your individual prescription and specific needs. During your consultation, we’ll provide a detailed cost estimate and discuss financing options to make the procedure accessible.
