LASIK vs SMILE Surgery: What Is the Difference and Which May Suit You?

Choosing between LASIK and SMILE surgery can feel overwhelming. Both are advanced laser vision correction procedures that reduce or eliminate your dependence on glasses. But they are not the same — and the right choice depends on your eyes, lifestyle, and visual goals.

At Bansal Eye Hospital, we have performed laser vision correction since 1997 and were the first in North India to offer LASIK surgery. Today, we also offer the latest flapless technologies, including SILK and SMILE. This guide breaks down the key differences.


What Is LASIK Surgery?

LASIK stands for Laser-Assisted In Situ Keratomileusis. It is the most widely performed vision correction procedure worldwide, with decades of clinical data supporting its safety.

How LASIK Works

Your surgeon creates a thin hinged flap on your cornea using a femtosecond laser. The flap is lifted, and an excimer laser reshapes the underlying tissue to correct your prescription. The flap is then repositioned and heals naturally.

Key steps:

  1. Numbing drops are applied

  2. A corneal flap is created and lifted

  3. Excimer laser reshapes the cornea

  4. The flap is repositioned and heals

Procedure time: 10–15 minutes for both eyes

Recovery: Most patients see clearly within 24 hours


What Is SMILE Surgery?

SMILE stands for Small Incision Lenticule Extraction. It is a newer, flapless procedure approved by the FDA in 2016.

How SMILE Works

Instead of a flap, SMILE uses a femtosecond laser to create a small, lens-shaped piece of tissue (a lenticule) inside the cornea. The surgeon removes it through a tiny 2–4 mm incision.

Key steps:

  1. Numbing drops are applied

  2. Femtosecond laser creates the lenticule

  3. A small incision is made

  4. The lenticule is extracted

  5. The cornea reshapes as it heals

Procedure time: 10–15 minutes for both eyes

Recovery: Most patients return to normal activities within 2–3 days

Which Procedure Is Right for You?

There is no single "best" procedure — only the best one for your eyes.

1. Your Prescription

LASIK treats myopia up to -12.00 D, hyperopia up to +6.00 D, and astigmatism up to 6.00 D.

SMILE is approved for myopia typically -1.00 to -10.00 D and astigmatism up to 3.00 D. It is not approved for hyperopia in most countries.

2. Your Corneal Thickness

LASIK removes more tissue due to the flap. SMILE preserves more corneal structure, making it an option for thinner corneas.

3. Dry Eye History

SMILE cuts fewer corneal nerves, so it is associated with fewer dry eye symptoms after surgery.

4. Lifestyle and Occupation

5. Age and Eye Health

Patients over 40 may be approaching presbyopia. Your surgeon may discuss monovision LASIK or other options.


The Advanced Option: SILK Surgery

At Bansal Eye Hospital, we also offer SILK (Small Incision Lenticule Keratoplasty) — the newest generation of flapless correction using the ELITA femtosecond laser from Johnson & Johnson Vision.

Frequently Asked Questions

Is SMILE better than LASIK?

Neither is universally better. SMILE suits dry eye or thin cornea patients. LASIK offers broader prescription range and faster recovery.

Can I choose which procedure I want?

You can express a preference, but the final recommendation depends on your corneal thickness, prescription, and eye health.

Is SMILE more expensive than LASIK?

Costs vary. At Bansal Eye Hospital, we offer transparent pricing and discuss all options during consultation.

How long do results last?

Both provide permanent corneal reshaping. Age-related presbyopia can still affect near vision later.

What if I'm not a candidate for either?

Alternatives include PRK, implantable contact lenses (ICL), or refractive lens exchange with toric IOLs.
