EVO ICL — Clear Vision Beyond the Limits of Laser
When myopia is very high or corneas are too thin for laser surgery, an Implantable Collamer Lens offers a remarkable alternative: a soft, biocompatible lens placed gently inside the eye. No corneal tissue is removed, and it’s fully reversible.
An additional lens, working with your eye
Not laser — an implant
EVO ICL is a tiny, flexible Collamer lens positioned just in front of your natural lens. Unlike laser surgery, it adds corrective power instead of reshaping the cornea — so no corneal tissue is removed.
Reversible by design
Because nothing is permanently altered in the cornea, the lens can be removed or exchanged by your surgeon if your needs ever change. Many patients value that peace of mind.
Who EVO ICL is ideal for
Suitability is always confirmed by examination — but ICL is often the right path for:
Very high myopia
Strong prescriptions that fall beyond the comfortable range of laser correction.
Thin corneas
When there isn’t enough corneal thickness to safely perform laser surgery.
Dry-eye-prone eyes
ICL doesn’t disrupt corneal nerves the way some laser procedures can.
Demand for night vision
Many patients report sharp, high-definition vision, including in low light.
Wanting reversibility
Those who prefer a correction that can be removed or updated later.
Active lifestyles
No corneal flap means no flap-related concerns from impact or sport.
When laser isn’t the answer, ICL often is
| Consideration | Laser (SMILE / LASIK) | EVO ICL |
|---|---|---|
| Best for | Low to moderate myopia | High myopia |
| Cornea | Reshapes & removes tissue | Untouched — nothing removed |
| Thin corneas | May not be suitable | Usually fine |
| Reversibility | Permanent | Removable / exchangeable |
| UV protection | Not applicable | Built into the lens |
How ICL surgery works
Detailed eye measurement
We map your eye precisely so a lens can be made to your exact prescription and eye dimensions.
Your custom lens is prepared
Each EVO ICL is made specifically for your eye — this is why planning ahead matters.
Gentle placement
Through a tiny opening, the soft lens is inserted and settles into position. The procedure itself takes only minutes per eye.
Fast, comfortable recovery
Many patients notice clearer vision within hours, with a short course of drops and routine follow-up checks.
Common questions about ICL
How strong a prescription can ICL correct?
ICL is designed for high myopia well beyond the usual laser range, and can also address astigmatism. Your surgeon confirms the exact correction possible for your eyes during your assessment.
Can I feel the lens once it’s in?
No. The lens sits inside the eye where you can’t feel it, and it isn’t visible to others. It simply works quietly with your eye’s own focusing system.
Is it really reversible?
Yes. Because no corneal tissue is removed, your surgeon can remove or exchange the lens if your vision needs change in the future.
Is ICL safe?
EVO ICL is a widely used, well-established procedure performed millions of times worldwide. As with any surgery, careful pre-screening is key — which is exactly why we examine your eyes thoroughly before recommending it.
How long should I plan to stay in Korea for ICL?
Because your lens is custom-made, planning ahead helps. Most international ICL patients plan for a few days in Korea for the exam, procedure, and an essential post-op check and we give you clear aftercare instructions for your recovery at home.
