contoura vs lasik

In today’s digital age, our eyes are under constant stress. Glasses and contact lenses have long been the go-to solutions for vision correction, but modern laser eye surgeries now offer patients a chance to see clearly—without external aids. Two popular procedures in India and across the world are SMILE surgery and Contoura Vision. While both promise life-changing results, one stands out as the smarter, safer, and more advanced choice: SMILE.

In this article, we’ll break down what each procedure involves, compare their advantages and risks, and explain why SMILE (Small Incision Lenticule Extraction)—which is FDA-approved—is fast emerging as the gold standard in laser vision correction.


What is SMILE Eye Surgery?

SMILE (Small Incision Lenticule Extraction) is a next-generation, minimally invasive laser eye surgery. Developed by Carl Zeiss Meditec and approved by the U.S. FDA in 2016, SMILE is designed to correct myopia (nearsightedness) and astigmatism with remarkable precision and minimal disruption to the eye’s natural structure.

How it works:

  • A femtosecond laser creates a tiny disc-shaped piece of tissue (called a lenticule) inside the cornea.

  • The surgeon then removes the lenticule through a 2–4 mm micro-incision, reshaping the cornea to correct vision.

  • No flap is created, unlike in LASIK or Contoura procedures.


What is Contoura Vision?

Contoura Vision is a topography-guided LASIK surgery. It uses a laser to reshape the cornea based on detailed corneal mapping. The goal is to correct not just the spectacle power but also minor imperfections in the corneal surface, potentially improving visual clarity and quality.

How it works:

  • A flap is created in the cornea using either a microkeratome or femtosecond laser.

  • An excimer laser then reshapes the cornea based on the topographic data.

  • The flap is repositioned after the correction is done.

Contoura is not yet FDA-approved for all types of vision corrections and remains a modified form of traditional LASIK.


SMILE vs Contoura Vision: Feature-by-Feature Comparison

Feature SMILE Surgery Contoura Vision (Topography-guided LASIK)
FDA Approval ✅ Yes, approved since 2016 ❌ Not approved for all indications
Type of Procedure Minimally invasive, no flap Flap-based surgery
Incision Size 2–4 mm 20 mm (flap)
Dry Eye Risk Very low Moderate to high (due to flap)
Healing Time Faster (due to small incision) Slightly longer due to flap recovery
Corneal Strength Post-Op More preserved (no flap) Weaker (flap weakens corneal integrity)
Suitability for Active Lifestyles Excellent Moderate (flap can dislocate with trauma)
Night Vision/Glare Issues Lower incidence Higher possibility (especially in early recovery)
Correction Accuracy High for myopia and astigmatism High, including minor corneal aberrations

Why SMILE is the Safer and Smarter Option

1. Minimally Invasive & Flap-Free

One of the biggest advantages of SMILE is that it doesn’t involve creating a corneal flap. Flap-based surgeries like Contoura or traditional LASIK can compromise the biomechanical strength of the cornea and are more prone to flap-related complications like dislocation, especially for people engaged in contact sports or physically demanding activities.

2. Lower Risk of Dry Eyes

SMILE preserves more corneal nerves since the surface is less disrupted. This results in significantly reduced chances of dry eyes, a common side effect of LASIK and Contoura procedures.

3. FDA-Approved and Backed by Global Research

Unlike Contoura Vision, which is still gaining regulatory traction, SMILE has been FDA-approved since 2016 for treating myopia and astigmatism. It’s supported by years of peer-reviewed studies, clinical trials, and global adoption in countries like the USA, Germany, and Japan.

4. Faster Healing and Recovery

Thanks to its tiny incision and tissue-preserving technique, SMILE offers:

  • Quicker visual recovery

  • Minimal discomfort

  • Faster return to normal activities

Most patients can resume work and light activities within 24–48 hours.

5. Long-Term Safety and Stability

Since SMILE does not involve ablation of the corneal surface (as in Contoura), the structural integrity of the eye is better preserved. This makes SMILE the preferred choice for long-term corneal stability, reducing the risk of post-operative complications like ectasia.


Who is a Good Candidate for SMILE?

You might be eligible for SMILE if:

  • You are 18 years or older

  • Your spectacle number is stable for at least 1 year

  • You have myopia (up to -10D) and/or astigmatism (up to -5D)

  • Your corneas are healthy and of adequate thickness

  • You are looking for a safer, flap-free alternative to LASIK or Contoura

If you have hyperopia (farsightedness), SMILE might not yet be suitable—but LASIK or other options can be considered in consultation with an eye specialist.


Common Myths Around SMILE vs Contoura Vision

Myth 1: Contoura gives “HD Vision” and SMILE doesn’t.
Reality: Both offer 6/6 vision or better. While Contoura uses corneal mapping to address surface irregularities, SMILE’s precision and safety make it more suitable for long-term outcomes.

Myth 2: SMILE is newer, so less tested.
Reality: SMILE has been in use globally for over a decade and is FDA-approved. It is backed by strong clinical evidence and millions of successful surgeries worldwide.

Myth 3: Contoura is more advanced because it uses topography.
Reality: SMILE is more technologically advanced in terms of surgical technique, precision, and minimal invasiveness.


Conclusion: SMILE Wins the Vision Correction Race

Both SMILE and Contoura Vision are effective, modern solutions for laser vision correction. However, when you compare them on safety, recovery, technology, and long-term outcomes, SMILE clearly emerges as the better option.

With its flap-free design, lower dry eye risk, faster healing, and FDA approval, SMILE provides not just clear vision—but peace of mind.

If you’re considering laser vision correction, consult an experienced ophthalmologist to check if you’re a candidate for SMILE. Investing in your eyes means investing in a better, safer future—and SMILE makes that future clearer than ever.


Frequently Asked Questions

Q1. Is SMILE more expensive than Contoura Vision?
A: SMILE may be slightly more expensive due to the advanced technology involved, but the safety and long-term benefits make it a more valuable investment.

Q2. How soon can I return to work after SMILE?
A: Most people return to work within 1–2 days, thanks to minimal discomfort and fast healing.

Q3. Does SMILE hurt?
A: The procedure is virtually painless and done under local anesthesia. Some mild discomfort may be felt for a few hours post-op.
