ICL Surgery – Frequently Asked Questions (FAQs)


1. What is ICL surgery?

ICL stands for Implantable Collamer Lens. It’s a vision correction procedure where a soft, biocompatible lens is implanted inside the eye to correct nearsightedness and astigmatism, offering a long-term alternative to glasses and contacts.


2. How is ICL different from LASIK?

ICL doesn’t use a laser or reshape your cornea. Instead, it adds a lens inside your eye to correct your vision. It's also reversible, making it a great option for patients with thin corneas or dry eyes who are not ideal candidates for LASIK.


3. Is the procedure painful?

No. Numbing eye drops are used during the procedure, so you won’t feel pain. Some patients may feel slight pressure, but the entire process is typically comfortable and quick — about 15–20 minutes per eye.


4. How long does it take to recover?

Most patients notice improved vision within 24 hours. Normal activities can usually be resumed in 1–2 days, though full visual stabilization may take a few weeks.


5. Is ICL surgery permanent?

Yes, but it’s also reversible. The lens is designed to stay in your eye permanently, but it can be removed or replaced if needed, offering long-term flexibility.


6. Am I a candidate for ICL?

You may be a good candidate if you:

  • Are over 21 years old
  • Have stable vision for at least one year
  • Have moderate to severe nearsightedness (with or without astigmatism)
  • Are not suitable for LASIK or LASEK due to thin corneas or dry eyes

7. Does ICL correct astigmatism?

Yes. There are Toric ICL lenses specifically designed to correct astigmatism as well as nearsightedness.


8. Will I still need glasses after ICL surgery?

Most patients achieve excellent vision without glasses or contacts. However, reading glasses may still be needed later in life due to natural aging (presbyopia).


9. Are there any side effects or risks?

As with any surgery, there are minor risks such as under- or over-correction, glare or halos at night, or the rare need to reposition the lens. Your doctor will discuss these in detail during your consultation.


10. How much does ICL surgery cost?

In Korea, ICL surgery typically costs ₩3,500,000–₩5,500,000 per eye, depending on the clinic, lens type, and post-op care package. Some clinics offer flexible payment plans.
