Vision correction procedures have advanced significantly, providing patients multiple options to reduce or eliminate their dependence on glasses and contact lenses. Two of the most popular laser eye surgeries today are SMILE (Small Incision Lenticule Extraction) and LASIK (Laser-Assisted In Situ Keratomileusis). Both procedures aim to improve vision but differ in technique, recovery, and suitability for eye conditions. This article compares SMILE vs LASIK, covering key aspects such as procedure, eligibility, cost, recovery, and patient experiences.
What is SMILE?
Overview
SMILE (Small Incision Lenticule Extraction) is a minimally invasive laser eye surgery designed to correct myopia (nearsightedness) and astigmatism. Unlike LASIK, it does not require the creation of a corneal flap, which can make it a preferred option for individuals with an active lifestyle.
Procedure
- A femtosecond laser creates a small, lens-shaped piece of tissue (lenticule) within the cornea.
- The surgeon makes a tiny incision through which the lenticule is removed, reshaping the cornea and correcting vision.
- Since no flap is created, the outer corneal surface remains largely intact.

Benefits
- No corneal flap, reducing the risk of flap-related complications.
- A minor incision results in faster healing and fewer dry eye symptoms.
- Better structural integrity of the cornea post-surgery.
What is LASIK?
Overview
LASIK is one of the most widely performed refractive surgeries. It is used to treat myopia, hyperopia (farsightedness), and astigmatism. It involves reshaping the cornea to improve how light is focused on the retina.
Procedure
- A femtosecond laser or microkeratome is used to create a thin corneal flap.
- An excimer laser reshapes the underlying corneal tissue based on the patient’s prescription.
- The flap is repositioned, allowing it to heal naturally without stitches.

Benefits
- Effective for a broader range of refractive errors.
- Rapid visual recovery, with most patients seeing improvements within 24 hours.
- Highly customisable procedure with wavefront-guided options available.
SMILE vs LASIK – Key Differences
Surgical Technique
- SMILE: No corneal flap; lenticule is removed through a small incision.
- LASIK: A corneal flap is created and lifted before laser reshaping.
Recovery Time
- SMILE: Slightly longer initial visual recovery, but fewer dry eye symptoms.
- LASIK: Faster visual clarity, usually within a day.
Suitability
- SMILE: Best for myopia and astigmatism, but not for hyperopia.
- LASIK: Can correct myopia, hyperopia, and astigmatism.
Risks and Complications
- SMILE: Reduced dry eye risk, but limited enhancement options.
- LASIK: Higher risk of dry eye, but more straightforward follow-up enhancements, if needed.
SMILE vs LASIK Cost
The cost of SMILE vs LASIK varies based on the clinic, surgeon expertise, and technology used for the surgery. On average:
- SMILE Surgery Cost: Starts at ₹65,000 per eye and can go up to ₹75,000 per eye.
- LASIK Surgery Costs: Starts at ₹15,000 per eye and can go up to ₹50,000 per eye.
Many clinics offer financing plans to make these procedures more accessible.
SMILE vs LASIK Recovery
Immediate Recovery
- SMILE: Patients can resume normal activities within a few days.
- LASIK: Faster initial recovery, but requires extra care to protect the corneal flap.
Long-Term Recovery
- SMILE: Less chance of dry eye and stronger corneal structure.
- LASIK: More lubricating drops may be required post-surgery.
Conclusion
SMILE and LASIK are effective vision correction procedures, each with unique advantages. SMILE is ideal for those seeking a minimally invasive option with reduced dry eye risk, while LASIK offers a quicker recovery with broader treatment capabilities. Consulting with an eye specialist can help determine which procedure aligns with your vision needs.

Frequently Asked Questions
LASIK generally provides faster visual recovery, but SMILE offers a lower risk of dry eye symptoms.
Yes, both LASIK and SMILE can correct astigmatism, though SMILE is not ideal for high degrees of nearsightedness or astigmatism.
Both procedures are safe when performed by an experienced surgeon. SMILE has fewer flap-related complications, while LASIK has been around longer with more long-term research data available.
Most patients achieve clear vision, but some may need reading glasses as they age, regardless of the procedure chosen.
