ICL (Implantable Collamer Lens)
A specialized lens implanted within the eye for reversible vision correction
What is ICL (Implantable Collamer Lens)?
ICL (Implantable Collamer Lens) is a procedure that corrects vision by implanting a specialized Collamer lens inside the eye. Unlike LASIK or LASEK, ICL does not require any reshaping of the cornea, preserving 100% of the corneal tissue.
It is especially suitable for patients with high myopia (-6.0D or greater) or corneas too thin for laser surgery. The implanted lens remains comfortably in the eye with no foreign body sensation and can be removed if needed, making it a reversible procedure.
The Collamer material offers excellent biocompatibility, adapting naturally within the eye without adverse reactions, and also provides UV protection to support long-term eye health.
Key Benefits of ICL
No Corneal Reshaping
Rather than reshaping the cornea with a laser, a lens is implanted inside the eye, preserving 100% of the corneal tissue.
Reversible Procedure
The implanted lens can be removed or replaced if necessary. Unlike LASIK/LASEK, your eyes can be restored to their original state.
Ideal for High Myopia
Safely corrects high myopia of -6.0D or greater that LASIK/LASEK cannot adequately address.
Superior Visual Quality
The lens itself delivers outstanding optical performance, resulting in excellent night vision and contrast sensitivity.

Surgical Procedure
STEP 1. Comprehensive Examination & Lens Order
ICL-specific tests including anterior chamber depth, endothelial cell count, and pupil size are performed, and a custom lens is ordered (approximately 1-2 weeks).
STEP 2. Topical Anesthesia & Micro-Incision
After topical anesthesia, a micro-incision of approximately 3mm is made at the corneal periphery.
STEP 3. ICL Lens Insertion
The folded ICL lens is inserted through the micro-incision into the eye, positioning behind the iris and in front of the natural lens.
STEP 4. Position Verification & Completion
The lens position and vision are verified. The incision heals naturally without sutures.

ICL's Greatest Advantage: Reversibility
ICL is the only vision correction surgery that can be reversed. The implanted lens remains semi-permanently in the eye, but can be removed or replaced if needed for other eye surgery or prescription changes. Since the cornea is never altered, your original eye condition is fully preserved.
