ICL is often right when…
Your power is high, your corneas are thin, borderline or irregular, your eyes lean dry, or laser has been found unsuitable for you. The lens can be removed if needed.
If your glasses are strong, the question is whether laser can safely correct that much power at all. For high short-sight, an implanted ICL lens is often preferred. Here is a comparison of the two, and how suitability is decided for your eyes.
The higher your short-sight, the more corneal tissue LASIK must remove to flatten the curve, and every cornea has a floor it shouldn't go below. Beyond a certain power, removing enough tissue would leave the cornea too thin to be safe. That's the point where ICL, which touches no corneal tissue, usually becomes the wiser route.
A like-for-like look at the two for strong short-sight specifically.
| ICL | LASIK | |
|---|---|---|
| How it corrects | Adds a soft lens inside the eye | Removes corneal tissue to reshape |
| High power range | Handles high short-sight well | Limited by safe corneal thickness |
| Thin / borderline cornea | No tissue removed, fine | Often rules laser out |
| Reversible | Yes, lens can be removed | No, permanent reshaping |
| Dry-eye tendency | Minimal, no corneal nerves cut | Can be more at first, then settles |
| Recovery | Usually days, varies | Usually days, varies |

Your assessment, your vision correction and follow-up visits are planned together, so the findings from your consultation carry through to the procedure and the reviews afterwards.

For high short-sight, ICL is often preferred, because it adds a lens inside the eye rather than removing corneal tissue. LASIK corrects by reshaping the cornea, and there's a limit to how much tissue can be safely removed before the cornea is left too thin. Beyond a certain power, ICL is frequently the option considered. The only way to know for your eyes is to measure them.
Loosely, short-sight beyond about -6.00 dioptres is often called high myopia, and beyond roughly -8.00 to -10.00 it becomes very high. There's no single hard cut-off where LASIK stops and ICL starts, because it also depends on your corneal thickness and shape. A thin cornea can rule laser out at a lower power; a thick, healthy one may allow it a little higher. The scan decides, not the label.
LASIK works by removing a small amount of corneal tissue to flatten the curve. The higher your power, the more tissue must be removed, and every cornea has a safe limit below which it shouldn't be thinned. Pushing laser beyond that risks weakening the cornea (ectasia). For high powers, ICL avoids this because it does not thin the cornea. ICL has its own risks, which are explained at your assessment.
In suitable eyes it is a well-established option, and the lens can be removed. Like any surgery it carries risks, which are explained before you decide. The ICL is a soft, biocompatible lens placed inside the eye in front of your natural lens. Because it removes no corneal tissue, it is often considered for high powers and to thin or borderline corneas. As with any procedure, suitability depends on the space inside your eye and a full assessment, which is done before it is recommended.
Yes. Unlike laser, which permanently reshapes the cornea, the ICL can be removed or exchanged if ever needed. Removal is itself a surgical procedure.
Possibly. A thick, healthy, regular cornea may allow laser to correct a higher power safely than a thin one would. This is why the decision is not made from the glasses number alone. Corneal thickness and shape are measured, and you are then told whether laser or ICL is suitable for your eyes.
It depends on your eyes and which option is suitable, which is known only after measuring. A written estimate is given after your assessment. Vision-correction procedures are elective and usually not covered by insurance. You can contact the hospital on WhatsApp or by phone.
One refractive suitability assessment measures your prescription, corneal thickness and shape, and the space inside your eye, everything needed to tell you whether ICL, LASIK, or neither is right. The surgeon who assesses you gives you the recommendation. Sometimes one eye is suitable for laser and the other for ICL.
