SMILE Eye Surgery in India: Procedure, Cost & Recovery

What Is SMILE Eye Surgery?

SMILE eye surgery in India is a widely performed flapless laser eye surgery in the world. The full name is Small Incision Lenticule Extraction, also called ReLEx SMILE, and it was developed by Carl Zeiss. The VisuMax femtosecond laser creates a thin, disc-shaped lenticule inside the cornea, and the surgeon removes it through a 2 to 3 mm side incision. The lenticule comes out; your myopia or astigmatism goes with it. A small incision is made to remove the lenticule; unlike LASIK, no corneal flap is created.

SMILE belongs to the same lenticule family as SILK, but on a different machine: SILK runs on J&J’s newer ELITA, SMILE on the long-proven VisuMax. At Planet LASIK by Centre For Sight, SMILE is performed by VisuMax-certified surgeons for adults with myopia up to -10.00 D and astigmatism up to 5.00 D. Book a LASIK workup

How SMILE Eye Surgery Works

SMILE reshapes the cornea from the inside:

Lenticule creation: the VisuMax fires ultra-fast femtosecond pulses to form a thin lenticule inside the cornea, sized to your prescription from your pre-operative eye maps.
Side incision: a 2 to 3 mm opening at the cornea’s edge, against the roughly 20 mm flap edge LASIK creates.
Lenticule extraction: the surgeon draws the lenticule out, changing the cornea’s curvature so light lands focused on the retina.

The surface stays intact, so around 90% of corneal nerves are preserved. That is why SMILE carries far lower dry-eye risk than flap-based LASIK.

Advantages of SMILE eye surgery

The advantages fall into three buckets.

Safety:

Flapless. No flap dislocation, striae, or epithelial ingrowth, ever.
A tiny incision, so infection risk drops sharply.
Superior biomechanical stability. The cornea stays stronger, which matters for contact sports and defence careers.

Comfort:

The laser treatment takes approximately 25–30 seconds, while the overall procedure takes about 10–15 minutes per eye.
Most of the corneal nerves are preserved, so dry eye stays uncommon and short-lived.

Vision quality:

Highly predictable outcomes; most candidates reach 20/20 or better.

Who Is a Candidate for SMILE Eye Surgery in India?

Good candidates are adults over 18 with a stable prescription. SMILE suits:

Blurry distance vision: road signs, whiteboards, or the TV never quite in focus (myopia).
A myopia power between -1.00 D and -10.00 D. Astigmatism up to 5.00 D doesn’t rule you out; it gets treated at the same time.
Individuals more prone to dry eye, as SMILE causes less nerve disruption.
Thin corneas that rule out flap-based LASIK
Athletes and defence aspirants. No flap, nothing to dislodge.

Standard Eligibility Criteria

Eligibility comes down to four things. You’re 18 or older. Your prescription has held steady for at least 12 months. Your cornea measures around 500 microns, enough tissue for the treatment plus a safe margin. And your eyes are otherwise healthy, with no active disease. One boundary to know: SMILE does not treat hyperopia, so for farsightedness, Custom Eyes LASIK or SmartSurf may fit, and beyond -10.00 D of myopia, ICL takes over.

Who Should Not Have SMILE

Pregnant or breastfeeding women (postpone, don’t cancel)
Keratoconus, glaucoma, or severe dry eye disease
Uncontrolled autoimmune conditions affecting healing
Prescriptions still changing year to year

SMILE Eye Surgery Procedure at Planet LASIK

SMILE eye surgery in India runs in three stages: the tests before, the laser treatment, and the first 24 hours.

Before SMILE Eye Surgery: Pre-Operative Tests

The work-up confirms candidacy and finalises the lenticule dimensions:

Visual and refraction tests, automated and manual, to fix your exact prescription.
Corneal measurement. Topography maps the surface, pachymetry measures thickness and rules out keratoconus. Thickness decides whether SMILE is on the table.
A general eye-health check: tonometry for pressure, dry-eye assessment, a dilated look at the retina.
Lenticule planning, which turns your eye maps into the exact tissue profile the VisuMax will cut.

Set aside about 90 minutes. Soft contact lens wearers stop lenses 1 to 2 weeks before testing; rigid lenses, 3 to 4 weeks.

During the SMILE Procedure

Numbing drops: drops only, no injections.
Docking: a patient interface gently positions and steadies your eye against the VisuMax.
Lenticule creation and extraction: the laser step takes 25 to 30 seconds; the surgeon then removes the lenticule through the 2 to 3 mm incision.
Both eyes, one sitting: 10 to 15 minutes per eye, and the incision seals itself without stitches.

After SMILE Eye Surgery: The First 24 Hours

Same-day discharge after a brief observation.
Prescribed drops: doctor-prescribed antibiotic, anti-inflammatory, and lubricating drops (detailed below).
Temporary symptoms: watering, grittiness, and light sensitivity on day one are normal.
Transport: arrange for someone to drive you home.

SMILE Eye Surgery Recovery Timeline

SMILE eye surgery recovery time is among the most comfortable in refractive surgery: the incision is tiny, there is no flap, and dry-eye symptoms stay minimal:

Timeline	What to Expect
First 24 hours	Mild watering, grittiness, light sensitivity. Vision starts clearing within hours. Rest with the eye shield on.
Day 2 to Day 7	Significant improvement. Desk work resumes in 2 to 3 days. Keep water, dust and fingers away from the eyes.
Week 2 to Week 4	Driving once cleared, workouts return, vision keeps sharpening.
1 to 3 months	Final visual quality settles. Routine check-ups from here on.

A week-by-week account lives in our SMILE recovery guide.

Risks, Complications & Side Effects of SMILE Eye Surgery

SMILE is among the safest laser vision procedures, but no surgery is free of risk. What can come up:

Temporary dry eyes, less common and shorter-lived than with LASIK. Typically gone in 4 to 6 weeks.
Mild light sensitivity for the first few days.
Halos or starbursts at night, usually resolving within 3 months.
Blurred or fluctuating vision in the first week. It settles.
Under- or over-correction. Rare, and an enhancement can fine-tune the result.
Lenticule extraction difficulty, very rare in experienced hands.
Infection, minimal risk with the tiny incision, and prescribed drops are the defence.

The temporary effects pass on their own. Actual complications are rare, and screening exists to keep them that way.

Safety & Success Rate of SMILE Eye Surgery

SMILE, performed on the VisuMax femtosecond laser, has one of the strongest track records in refractive surgery. From published SMILE clinical data:

Over 6.5 million SMILE procedures performed worldwide.
Most patients achieve 20/20 or better uncorrected vision.
Over 99% reach 20/40 or better, the legal driving standard in most countries.
US FDA approval in 2016 for myopia and 2018 for myopic astigmatism.

At Planet LASIK, every case is screened with a full work-up and performed by VisuMax-certified surgeons; that is how these numbers hold up in practice.

Medications After SMILE Eye Surgery

Three types of drops support your recovery. Follow the exact schedule your surgeon prescribes:

Antibiotic drops: prevent infection at the incision. Typically 4 times a day for the first week.
Anti-inflammatory (steroid) drops: control healing inflammation, tapered over 3 to 4 weeks from 4 times a day downwards.
Lubricating drops: support the tear film while nerves recover. Used liberally for 2 to 3 months, longer if your eyes run dry.

Never stop a drop on your own; the taper schedule exists for a reason.

Do’s and Don'ts After SMILE Eye Surgery: Aftercare Guide

The first two weeks matter most.

Dos:

Use all three sets of drops on schedule.
Use a protective shield while sleeping, first 2 to 3 nights.
UV-protective sunglasses whenever outdoors, for two weeks.
Keep screen sessions short for the first 2 days.
Attend every follow-up, Day 1 through Month 3.

Don’ts:

Don’t rub, press, or touch your eyes. The rule candidates reak most often.
No swimming, hot tubs, or dusty environments for two weeks.
Skip eye makeup for a week. Hard workouts, two.
Don’t splash water into the eyes for the first week; a face wipe does the job.

When to Call Your Doctor After SMILE Eye Surgery

Discomfort, watering, and haze are expected in the first 48 hours. Call your Planet LASIK surgeon the same day if you notice:

Severe eye pain that prescribed medication doesn’t touch
A sudden drop in vision, or new blur after Day 2
Persistent redness, discharge, or swelling
New flashes, floaters, or a curtain-like shadow (possible retinal issue)

SMILE vs LASIK vs PRK vs Contoura: How to Choose

The SMILE vs LASIK question comes down to the flap: LASIK makes one, SMILE doesn’t. The SMILE vs Contoura Vision question is about what needs fixing: Contoura excels at corneal surface irregularities, SMILE at flapless simplicity. PRK removes the surface layer instead. The side-by-side:

Parameter	SMILE	LASIK	PRK	Contoura Vision
Technique	Lenticule out via 2 to 3 mm incision	Corneal flap created, then reshaped	Corneal epithelium removed, then laser reshapes underneath	Topography-guided LASIK with flap
Corneal flap	No	Yes (~20 mm edge)	No	Yes
Myopia range	Up to -10.00 D	Up to -8.00 D	Up to -6.00 D	Up to -12.00 D
Astigmatism	Up to 5.00 D	Up to 6.00 D	Up to 5.00 D	Up to 6.00 D
Dry eye risk	Very low (90% nerves preserved)	Higher	Moderate	Similar to LASIK
Thin corneas	Suitable	Not suitable	Suitable	Limited
Recovery to clear vision	1 to 3 days	1 to 2 days	5 to 7 days	1 to 2 days

Pick SMILE for flapless correction with the lowest dry-eye risk, within -10.00 D. Planet LASIK offers every procedure in this table, so the recommendation follows your eyes, not a sales pitch.
