LASIK and SMILE eye surgery in India draws international patients mainly because of price. But cost is the second question. The first is whether your eyes, your corneal anatomy and your prescription suit either operation at all.
Both procedures correct refractive error by changing the optical power of the cornea. They do it in different ways, and the difference matters for safety, recovery and who qualifies. This guide covers how each works, how candidates are assessed, what can go wrong, and how Indian prices compare with the US, UK, Turkey and the UAE.

What LASIK and SMILE correct
Refractive errors occur when the eye does not focus incoming light precisely on the retina. The principal ones are:
- Myopia (short-sightedness)
- Hypermetropia (long-sightedness)
- Astigmatism
The cornea provides a major share of the eye’s focusing power. Changing its curvature therefore changes where light lands. LASIK and SMILE are corneal refractive procedures. Neither removes the natural crystalline lens, so the lens can still develop a cataract later in life.
How LASIK works
LASIK stands for laser-assisted in situ keratomileusis. The surgeon creates a thin corneal flap, lifts it, and uses an excimer laser to reshape the stromal tissue underneath. The flap is then laid back in place.
Older systems cut the flap with a mechanical blade (microkeratome). Modern LASIK commonly uses a femtosecond laser instead. The aim is not to “remove part of the cornea”. The laser changes the curvature of the optical zone so that light focuses more accurately on the retina.
How SMILE works
SMILE stands for small-incision lenticule extraction. There is no conventional flap. A femtosecond laser forms a precisely shaped piece of stromal tissue, called a lenticule, inside the cornea. The surgeon removes it through a small incision. Removing the lenticule changes the shape and power of the cornea.
SMILE does not use the excimer-laser ablation that LASIK relies on.
LASIK and SMILE compared
| Feature | LASIK | SMILE |
|---|---|---|
| Main lasers | Femtosecond (flap) plus excimer (ablation) | Femtosecond only |
| Corneal flap | Yes | No conventional flap |
| Stromal tissue | Ablated | Lenticule removed |
| Access | Flap-based | Small incision |
| Main applications | Myopia, hypermetropia and astigmatism, depending on platform and patient | Mainly myopia and myopic astigmatism |
| Visual recovery | Usually rapid | Usually rapid |
| Suitability | Decided by corneal and ocular assessment | Decided by corneal and ocular assessment |
The question is not which procedure is “better”. It is which one suits your prescription, corneal anatomy and visual needs. Do not choose from a marketing name alone.
Why corneal thickness and shape matter
Refractive surgery permanently changes corneal structure, so the surgeon must judge whether your cornea can safely tolerate the planned change. Corneal ectasia and other corneal abnormalities can make surgery unsuitable. Stable refraction and absence of corneal disease are central to selecting LASIK patients.
Corneal topography and tomography can reveal abnormal curvature patterns that a routine eye examination misses. A cornea that looks acceptable at the slit lamp may still fail these tests. Patients with significant corneal disease may need a different approach altogether, including evaluation for corneal transplantation.
The goal is not just a target spectacle prescription. It is correction while keeping enough corneal strength.
Who may be considered for laser vision correction
A suitable candidate generally has:
- A stable refractive prescription
- A healthy cornea
- Appropriate corneal thickness and architecture
- No significant untreated eye disease
- Realistic expectations
- A prescription within the treatment range of the specific procedure and laser platform
Older textbook criteria for LASIK list an age above 20 years, refraction stable for at least 12 months, and no corneal pathology [1]. Modern selection is more individual than a single age or thickness cutoff.
The preoperative assessment
A thorough assessment is among the most important parts of refractive surgery. Your ophthalmologist may evaluate:
- Refraction: the exact amount and type of error.
- Corneal shape: topography or tomography to find irregular curvature and early ectatic disease.
- Corneal thickness: pachymetry, to judge whether enough tissue will remain after treatment.
- Tear film and ocular surface: dry eye and surface disease affect comfort and visual quality afterwards.
- Pupil and visual quality: pupil size and higher-order aberrations in selected patients.
- Overall eye health: any other condition that could affect the result.
India’s Centre for Sight advises that a thorough centre spends 60–90 minutes on pre-operative testing, and says rushed screening is a reason to walk away [4].
What to expect after surgery
Visual recovery after LASIK is generally rapid compared with surface-ablation procedures such as PRK, and early postoperative pain is relatively mild [1]. Rapid improvement does not mean your eyes have reached their final state. Vision can fluctuate during early healing.
Some patients experience:
- Dryness
- Fluctuating vision
- Glare and halos
- Difficulty with night vision
- Temporary light sensitivity
Contrast sensitivity and night-vision concerns have historically been associated with laser correction [2].
Possible complications
No corneal refractive procedure is risk-free. With LASIK, complications can include flap displacement or wrinkling, epithelial ingrowth and other interface problems, and irregular astigmatism [1]. Other possible problems include persistent dry eye, residual refractive error, regression and optical symptoms.
SMILE avoids a conventional flap, but that does not eliminate complications or guarantee better visual quality for every patient. Centre for Sight reports that about 2–5% of patients need an enhancement consultation within 12 months, so ask whether that is covered in your quote [4].
What about presbyopia?
This is one of the most important limitations. LASIK and SMILE correct the refractive error you have now. They do not stop presbyopia, the age-related loss of near focus. They also do not prevent age-related changes in the natural lens, and some patients eventually need cataract surgery.
A person with a successful result at 25 may still need reading glasses in their mid-40s. “Never needing glasses again” is not a universal outcome.
LASIK and SMILE versus glasses and contact lenses
Glasses remain the simplest and safest correction for many people. Contact lenses offer a wider field of view without spectacles, but need proper fitting, hygiene and ongoing care. Refractive surgery changes the eye itself.
The decision balances convenience, lifestyle, surgical risk, cost, visual expectations and long-term eye health.
When laser refractive surgery may not be appropriate
- Unstable refraction
- Significant corneal disease
- Suspected keratoconus or corneal ectasia
- Inadequate corneal structural reserve
- Significant ocular-surface disease
- Certain systemic or ocular conditions
- Unrealistic expectations
Where a patient is found unsuitable, alternatives include surface treatment (PRK) for thin corneas and implantable collamer lenses (ICL) for very high prescriptions [4].
LASIK and SMILE cost in India compared with other countries
Centre for Sight, one of India’s largest eye-care chains, published this price list in September 2026. Its table lists these amounts for both eyes [4]:
| Procedure (India) | Both eyes, INR | Both eyes, approx. USD |
|---|---|---|
| Standard LASIK | ₹35,000 – ₹55,000 | $365 – $575 |
| Femto-LASIK | ₹76,000 – ₹1,45,000 | $790 – $1,510 |
| Contoura (topography-guided) LASIK | ₹65,000 – ₹1,45,000 | $680 – $1,510 |
| SMILE | ₹1,03,000 – ₹1,46,300 | $1,070 – $1,525 |
| PRK | ₹30,100 – ₹69,000 | $315 – $720 |
The same source says pre-operative tests (₹3,000–₹10,000), medicines, lubricating drops and follow-ups are often billed separately, and that metro cities run 15–30% above tier-2 and tier-3 cities. Converted at about ₹96 per US dollar (October 2026).
Halving those both-eye figures gives a rough per-eye price for comparison:
| Country | LASIK per eye | SMILE per eye | Source |
|---|---|---|---|
| India (approx., half of the both-eye figures) | $180 – $755 | $535 – $760 | [4] |
| United States | About $2,246 average | Not compared here | [5] |
| United Kingdom | £995 – £2,395 | £1,500 – £2,500 | [6] |
| Turkey | $900 – $1,500 | Often $1,500 – $3,000 (Istanbul clinics) | [7], [8] |
| UAE | AED 3,000 – 12,000 (per eye or both eyes not stated) | Not compared here | [9] |
Other Indian providers list higher figures for premium platforms, and the sources above differ in what they include. Use this table to see the scale of the difference, and ask for an itemised written quote that says whether it is per eye or for both.
Planning the trip
Centre for Sight suggests budgeting two to three days for pre-operative testing, surgery and the day-one check [4]. Standard follow-up is at day 1, week 1 and month 1. Before you travel, ask:
- Which follow-up visits can be done by an ophthalmologist near home?
- What is the refund or alternative if I am found unsuitable after I arrive?
- Who will review my results after I return?
Questions to ask your ophthalmologist
- Which procedure is appropriate for my corneal shape and prescription?
- Is my prescription stable?
- What do my corneal topography and tomography show?
- Is my corneal thickness adequate?
- What visual symptoms could I have at night?
- What is my risk of persistent dry eye?
- Will I still need glasses for reading later in life?
- What happens if some refractive error remains?
- What alternatives do I have if laser surgery is unsuitable?
- What does my surgeon consider a realistic outcome?
The decision is more than LASIK versus SMILE
LASIK and SMILE eye surgery should be treated as an individual corneal decision, not a contest between two brand names. LASIK has a long history and an established role. SMILE offers a different way of changing corneal shape without a conventional flap. The sensible first step is a detailed examination, not choosing the procedure first.
