If your glasses power is high, say −7 or beyond, or your corneas are on the thinner side, you may have been told that "normal LASIK" isn't ideal. That is not a dead end. It usually means the choice moves between SMILE, LASIK variants and ICL. Here is how they compare, and what decides which one is right.
The three options at a glance
| LASIK (Femto / Contoura) | SMILE | ICL | |
|---|---|---|---|
| How it works | Flap created; laser reshapes the cornea | Small lenticule removed through a tiny incision; no flap | A thin lens placed inside the eye, in front of the natural lens. |
| Corneal tissue removed | Yes | Yes | No. |
| Best suited to | Low to moderate powers with adequate corneal thickness | Low to moderate myopia (with or without astigmatism) within its range | Higher powers, thin corneas, or where laser isn't safe. |
| Reversible? | No | No | The lens can be removed or exchanged. |
| Typical recovery | Quick | Quick | Quick, with closer pressure monitoring early on. |
Why high power changes the choice
Laser procedures (LASIK and SMILE) correct power by removing corneal tissue. The higher the power, the more tissue must be removed. Every cornea needs a safe amount of tissue left behind, so:
- with high power and a thick cornea, laser may still be possible
- with high power and a thinner cornea, removing that much tissue may be unsafe, and ICL becomes the safer option
- corneal shape matters too: an irregular or keratoconus-suspect cornea needs very careful evaluation, and may rule out laser entirely.
The tests that decide
A proper refractive work-up in Delhi NCR should include:
- corneal topography/tomography (shape and regularity)
- pachymetry (corneal thickness)
- refraction over time, to confirm the power is stable
- dry-eye assessment
- for ICL: anterior chamber depth and endothelial cell count, to ensure there is space for the lens and the inner cornea is healthy.
If a centre recommends a procedure before these tests are done, ask why.
Cost in Delhi NCR
LASIK and SMILE: indicatively ₹40,000–₹1,20,000 for both eyes, depending on the technique, the platform and the inclusions.
ICL: usually priced separately, because the lens is a major part of the cost. Toric ICLs (for astigmatism) cost more. Ask for a written, itemised both-eye estimate after your assessment.

Delhi NCR considerations
Pollution season: dry eye and irritation can be worse from late October to January. Discuss timing and eye protection with your surgeon. See our guide to LASIK and cataract surgery in pollution season.
Follow-ups: next-day and later reviews are essential. With traffic between Gurugram, Noida and Delhi, choose a centre that's practical to reach.
Corporate cover: some corporate group policies in Gurugram and Noida cover refractive surgery above a dioptre threshold. Check your policy.

Questions to ask your surgeon
- What are my corneal thickness and topography results?
- Am I eligible for LASIK, SMILE and ICL, and why do you recommend one?
- How much tissue would laser remove, and what would remain?
- For ICL: what are my anterior chamber depth and endothelial count?
- What follow-up schedule do you recommend, including long-term checks?

Clear answers
Questions families ask
What is the maximum power for LASIK?
There is no single cut-off. It depends on corneal thickness and shape. Your topography and pachymetry decide.
Is ICL safer than LASIK for high power?
For high powers or thin corneas, ICL is often the safer choice because it doesn't remove corneal tissue. It is intraocular surgery, so it has its own risks, which your surgeon should explain.
Is SMILE better for high myopia?
SMILE treats myopia within its eligibility range. For very high powers, ICL may be recommended instead.
Can ICL be removed?
Yes, the lens can be removed or exchanged if needed.
