LASIK vs ICL
Which Is the Better Option for Correcting High Myopia?
A detailed guide to help you choose between LASIK and implantable contact lenses
When LASIK Is Not Enough
LASIK is the most popular choice for vision correction, but it is not suitable for everyone. Patients with high myopia (above -8 to -10 diopters), thin corneas, or chronic dry eyes may not be ideal candidates for LASIK. In these cases, ICL (Implantable Collamer Lenses) offer an excellent alternative that can correct very high degrees of myopia with exceptional accuracy.
The ICL is a lens made from biocompatible Collamer material, a unique material combining collagen and polymer. This lens is implanted inside the eye between the iris (the colored part of the eye) and the natural lens, where it works together with the natural lens to properly focus light on the retina.
One of the most important advantages of ICL is that it does not alter the corneal structure at all. This means the procedure is fully reversible - the lens can be removed or replaced at any time in the future. The lens also provides built-in protection against harmful ultraviolet rays.
How Does ICL Work?
Comprehensive eye measurements and lens ordering (custom-made for your eye)
On procedure day, numbing drops are applied
A tiny incision (3mm) is made at the edge of the cornea
The folded ICL lens is inserted through the incision
The lens unfolds and is positioned behind the iris
No stitches needed - the incision self-seals
Quick ICL Facts
Comprehensive Comparison: LASIK vs ICL
| Criteria | LASIK | ICL |
|---|---|---|
| How It Works | Reshapes cornea with excimer laser | Implants a lens inside the eye |
| Reversibility | Permanent (not reversible) | Fully reversible (lens can be removed) |
| Prescription Range | Up to approximately -10 D | Up to -20 D (or more) |
| Cornea Modification | Yes - permanently reshapes cornea | No - cornea untouched |
| Corneal Thickness | Requires adequate thickness | Not dependent on corneal thickness |
| Procedure Time | 10-15 minutes (both eyes) | 15-20 minutes per eye |
| Recovery Time | 1-2 days | 2-3 days |
| Visual Quality | Excellent for moderate prescriptions | Excellent, especially for high prescriptions |
| Dry Eye Risk | Temporary dry eye common | Very low dry eye risk |
| UV Protection | No built-in protection | Built-in UV protection |
| Cost | Lower | Higher (custom lens) |
| Best For | Mild to moderate prescriptions | High prescriptions, thin corneas |
When Is ICL the Better Choice?
Your doctor may recommend ICL over LASIK in the following situations
High Myopia (-8 D and above)
ICL can correct prescriptions up to -20 diopters with excellent visual quality, while LASIK results may be less predictable beyond -10 D.
Thin Corneas
LASIK requires adequate corneal thickness to safely create a flap. ICL does not depend on corneal thickness since it is placed inside the eye.
Chronic Dry Eyes
LASIK can temporarily worsen dry eyes. ICL has minimal impact on tear film since the cornea is barely touched during the procedure.
Desire for Reversibility
If you value the option to reverse or update your vision correction in the future, ICL is the only reversible option among the two.
Keratoconus Concerns
Patients with early keratoconus or borderline corneal topography may be safer with ICL since it does not weaken the cornea.
Young Patients with Changing Prescriptions
Since ICL is removable and replaceable, it offers flexibility for younger patients whose prescriptions may still be evolving.
The Reversibility Advantage
One of the most attractive features of ICL lenses is that they are fully reversible. Unlike LASIK, which permanently alters the corneal structure, an ICL lens can be removed or replaced at any time. This means you are not "locked in" to the result forever.
This flexibility is especially important for younger patients. If your prescription changes over time, or if newer and better technologies become available in the future, you can simply replace the lens. Removing the lens also returns your eye to its original natural state.
Additionally, if you later need cataract surgery in the future, the ICL lens is simply removed during that procedure. Having ICL does not affect future eye treatment options.
Cost Considerations
LASIK Cost
LASIK is typically less expensive than ICL because it does not involve a custom lens. The cost depends on the technology type used (standard, femto, or CONTOURA).

ICL costs more due to the custom lens manufactured to your eye specifications in Switzerland. The cost includes the lens, procedure, and follow-up. However, the investment is worthwhile, especially for those who cannot have LASIK.

Frequently Asked Questions
What is the difference between LASIK and ICL?
LASIK reshapes the cornea with a laser to correct vision and is a permanent procedure. ICL (Implantable Collamer Lens) is a small lens implanted inside the eye behind the iris and in front of the natural lens. ICL is reversible and does not alter corneal structure.
Is ICL better than LASIK for high myopia?
Yes, ICL is typically the better option for patients with high myopia (above -8 to -10 diopters). LASIK can correct up to about -10 diopters but may not be suitable for very high prescriptions due to the amount of corneal tissue that needs to be removed. ICL can correct up to -20 diopters with excellent accuracy.
Is the ICL procedure reversible?
Yes, and this is one of the biggest advantages of ICL. The lens can be removed or replaced at any time if your prescription changes or if better technologies become available. This flexibility makes ICL an attractive option, especially for younger patients.
How much does ICL cost compared to LASIK in Oman?
ICL surgery costs more than LASIK because it involves a custom-made imported lens manufactured to your eye specifications. The exact cost depends on the lens type and degree of correction needed. Book a free consultation at Finland Eye Center for an accurate price quote.
How long does the ICL procedure take?
The ICL procedure is quick, taking about 15-20 minutes per eye. It is performed under local anesthesia with drops. Most patients notice immediate vision improvement and can return to work within 2-3 days.
