Back to daily life in 1-2 days
Implantable Collamer Lens (ICL) places a special lens inside the eye without reshaping the cornea, opening a new path for those with extreme myopia or who've been told their cornea is too thin for LASIK/LASEK. Because the cornea is preserved, the burden of dry eye is lighter, and as a reversible procedure with a removable lens, it offers extra peace of mind. For anyone who gave up thinking vision correction wasn't possible for them, it offers the chance of clear sight once more.
A special lens is implanted inside the eye without reshaping the cornea — ideal for extreme myopia or thin corneas unsuitable for LASIK/LASEK. Reversible and removable if needed.
- Cornea preserved
- Extreme myopia OK
- Reversible
1Who it's for
Especially suited to those with very high, extreme myopia or who've been told their cornea is too thin for laser correction. It's also a good alternative for those who wish to preserve the cornea without cutting it, or who have significant dry eye that makes LASIK/LASEK uncomfortable. It's recommended for those who want crisp visual quality while also valuing reversibility. Since suitability requires adequate internal eye space and anterior-chamber depth, candidacy is confirmed by detailed exam.
2How it works
First, numbing drops make the eye comfortable, then a very small incision is made at the edge of the cornea. The special lens — crafted to your pre-op measurements — is gently folded and inserted into the eye, then unfolded and positioned precisely in the space between the iris and your own natural lens. Since neither the cornea is cut nor the natural lens removed, the eye's own structure is preserved. The incision is small enough that stitches are usually unnecessary, and both eyes are typically finished in about fifteen minutes.
3Recovery & aftercare
Most patients return to daily life within one to two days, and because the cornea isn't reshaped, vision tends to clear relatively quickly. It's very important to verify, right after surgery and at later stages, that the lens is well seated and eye pressure is stable. At Healing Eye, your 1:1 dedicated surgeon checks this personally, so the same doctor consistently watches over how the lens inside your eye is settling. Since the lens stays within the eye, our lifetime surgery guarantee provides reassuring long-term care to match.

Frequently Asked Questions
Is it dangerous to put a lens inside the eye?
ICL is a well-established, proven vision-correction method, and the lens is designed to sit stably within the eye. Suitability is judged carefully through detailed testing, and because the lens can be removed if needed it's reversible — so let us fully address any safety questions in a free consultation.
Can it correct very high prescriptions?
A major strength of ICL is its ability to correct a wide range, including extreme myopia beyond the reach of laser correction. Your individual range depends on eye condition, so in a free consultation after a detailed exam, we'll tell you precisely whether your prescription can be corrected.
Will I feel or see the lens inside my eye?
The ICL lens is designed to settle naturally inside the eye, so it usually causes little to no foreign-body sensation and isn't visible from the outside. We'll explain the adaptation process and individual differences in detail during a free consultation, so please feel free to ask.
