If you’ve been told you’re not a candidate for LASIK or you have a higher prescription that glasses and contacts aren’t fully solving, EVO ICL® may be another option worth exploring.
In this episode of Days of Our Eyes, Dr. King and Dr. Cha explain Implantable Collamer® Lens surgery, also called EVO ICL, including how it works, who it’s for, and what recovery looks like.
EVO ICL stands for implantable collamer lens.
This procedure corrects vision by placing a specially designed lens inside the eye. Unlike glasses or contact lenses, which sit on the outside of the eye, or LASIK and PRK, which reshape the cornea, EVO ICL adds a lens inside the eye to help focus light properly.
The lens is positioned:
The goal is to improve vision without permanently reshaping the cornea.
The main difference is where the vision correction happens.
With LASIK, PRK, and SMILE, vision is corrected by changing the shape of the cornea.
With EVO ICL, the cornea is not permanently altered. Instead, a lens is placed inside the eye to correct the prescription.
One of the advantages of EVO ICL is that it is reversible, while corneal laser procedures create permanent changes to the surface of the eye.
EVO ICL may be a strong option for patients who:
It can be especially helpful for people with higher prescriptions who may not qualify for LASIK.
EVO ICL is currently used to correct:
It is designed for nearsighted prescriptions and can often correct a wider range than laser vision correction procedures.
At Alliance Vision Institute, the team uses the EVO ICL, which features a modern lens design with built-in openings called fenestrations.
These allow fluid inside the eye to flow naturally after surgery. This design helps streamline the procedure and reduces the need for additional pre-treatment steps that were commonly required with earlier generations of ICL technology.
The result is a more efficient surgical experience with improved safety and convenience.
Unlike LASIK, which is performed in a laser suite, EVO ICL is performed in a surgery center.
During the procedure:
Patients receive mild anesthesia to stay comfortable and relaxed during the procedure.
Because the cornea is the fastest-healing tissue in the body, recovery often begins quickly.
Recovery after EVO ICL is generally straightforward.
Patients typically use prescription eye drops for about one week while the eye heals and inflammation settles.
Many people notice vision improvement the same day as surgery, with vision continuing to sharpen over the days that follow.
Because the procedure takes place inside the eye, your surgeon will monitor healing closely during follow-up visits.
This is a common question, and the answer is no.
The lens sits behind the iris and is not visible when someone looks at your eye. Modern lens designs also include non-reflective coatings, so they do not create a noticeable shine or glare.
From the outside, the eye looks natural.
EVO ICL is an advanced vision correction option for patients with nearsightedness or astigmatism who may not be candidates for LASIK or who want an alternative that does not permanently reshape the cornea.
Because the lens is placed inside the eye and can correct a wide range of prescriptions, EVO ICL offers another pathway toward clear vision with reduced dependence on glasses or contact lenses.
The best way to know whether EVO ICL is right for you is through a complete eye evaluation and consultation.
