LASIK vs SMILE vs SILK vs Contoura: Which Eye Surgery Is Best in 2026?

By Bansal Eye Hospital, Ambala

If you are tired of glasses or contact lenses, 2026 is an excellent time to consider vision correction. But with so many options—LASIK, SMILE, SILK, and Contoura—choosing the right procedure can feel overwhelming. The truth? There is no single "best" surgery for everyone. The best procedure is the one that matches your eyes, your lifestyle, and your visual goals.

In this guide, we break down each option in simple terms so you can have an informed conversation with your eye surgeon.

What Is Laser Vision Correction?

Laser vision correction reshapes the cornea—the clear front surface of your eye—to correct:

• Nearsightedness (Myopia) — difficulty seeing distant objects
• Farsightedness (Hyperopia) — difficulty seeing close objects
• Astigmatism — blurred vision due to irregular corneal shape

The goal is simple: reduce or eliminate your dependence on glasses and contact lenses.

1. LASIK (Laser-Assisted In Situ Keratomileusis)

What Is LASIK?

LASIK is the most widely performed and well-established laser vision correction procedure. A femtosecond laser creates a thin corneal flap, which is gently lifted. An excimer laser then reshapes the cornea beneath it. The flap is repositioned and heals naturally—no stitches needed.

Why Patients Choose LASIK

• Extensive track record — over two decades of proven results
• Fast visual recovery — most patients see clearly within 24–48 hours
• Treats a wide range of prescriptions including myopia, hyperopia, and astigmatism
• Widely available at eye centres across India

Points to Consider

• Corneal flap — while rare, trauma can dislodge the flap later
• Dry eye risk — moderate, due to corneal nerve disruption during flap creation
• Not ideal for thin corneas or very high prescriptions

2. SMILE (Small Incision Lenticule Extraction)

What Is SMILE?

SMILE is a flapless, minimally invasive procedure. A femtosecond laser creates a thin, lens-shaped piece of tissue (called a lenticule) inside the cornea. The surgeon removes it through a tiny 2–4 mm incision, reshaping the cornea and correcting vision.

Why Patients Choose SMILE

• No flap — eliminates flap-related complications entirely
• Less dry eye — fewer corneal nerves are disturbed
• Excellent for active lifestyles — athletes, swimmers, and defense personnel
• Faster return to sports — typically 2–3 weeks vs. 4 weeks for LASIK

Points to Consider

• Limited prescription range — standard SMILE treats myopia up to -10D and astigmatism up to -5D; does not correct hyperopia
• Fewer enhancement options compared to LASIK if residual power remains

3. SILK (Smooth Incision Lenticule Keratomileusis) — The Newest Generation

What Is SILK?

SILK is the latest advancement in flapless lenticule-based vision correction. Developed by Johnson & Johnson Vision and performed on the ELITA femtosecond laser platform, SILK uses a bi-convex lenticule design with ultra-low laser energy (~40–60 nanojoules) to create an exceptionally smooth corneal interface.

Why SILK Is Generating Excitement

• Lowest dry eye risk — the bi-convex design avoids the corneal nerve-rich areas that older lenticule procedures may disrupt
• Fastest recovery — clinical trials show 86% of patients achieved 20/20 vision at 1 week, and 96% at 6 months
• Preserves corneal strength — up to 95% of biomechanical strength maintained
• Excellent for athletes — no flap, tiny incision, quick return to activity
• Treats myopia up to -12D and astigmatism up to -6D

Points to Consider

• Newer technology — long-term data (10+ years) is still being collected
• Limited availability — only select centres in India offer SILK
• Not yet approved for hyperopia correction

4. Contoura Vision (Topography-Guided LASIK)

What Is Contoura Vision?

Contoura Vision is an advanced form of Femto LASIK. Before surgery, a device called the Topolyzer scans your cornea and maps 22,000 unique elevation points. The excimer laser then uses this detailed topographic map to create a fully personalized treatment plan that corrects your prescription and smooths out microscopic corneal irregularities.

Why Patients Choose Contoura Vision

• Personalized treatment — tailored to your unique corneal surface
• Better quality of vision — especially for patients with subtle corneal irregularities
• Fewer night vision issues — tends to reduce halos, glare, and starbursts
• Higher chance of 6/5 vision (better than 20/20) in suitable candidates

Points to Consider

• Corneal flap — same flap-related considerations as standard LASIK
• Dry eye risk — similar to Femto LASIK
• Higher cost — reflects additional diagnostic technology
• Best for suitable candidates — requires detailed corneal mapping to confirm eligibility

Which Surgery Is Right for You?

The honest answer is: it depends on your eyes and your life.

Choose SMILE or SILK if:

• You play contact sports or lead a very active lifestyle
• You have dry eyes or are prone to dryness
• You want the lowest possible risk of flap-related complications
• You have myopia with or without astigmatism within treatable range

Choose Contoura Vision if:

• You have subtle corneal irregularities affecting visual quality
• You experience glare, halos, or poor night vision
• You want the most personalized, topography-guided treatment available
• You are seeking the sharpest possible quality of vision

Choose LASIK if:

• You have a straightforward prescription and healthy corneas
• You want a well-established procedure with predictable outcomes
• You need hyperopia correction
• Budget is a consideration

Frequently Asked Questions (FAQ)

1. Which is better: SILK or SMILE?

SILK represents the newest generation of flapless lenticule technology. It features a bi-convex lenticule design with ultra-low laser energy, potentially resulting in smoother corneal interfaces and lower dry eye risk compared to standard SMILE. However, SMILE has a longer track record. Your eye surgeon can help determine which is more suitable for your specific eyes.

2. Is Contoura Vision better than LASIK?

Contoura Vision is an advanced, topography-guided form of LASIK. It provides more personalized treatment by mapping 22,000 corneal points, which can result in sharper vision and fewer night vision issues—especially for patients with subtle corneal irregularities. For straightforward prescriptions on regular corneas, the practical difference may be small.

3. Which surgery has the fastest recovery?

SILK offers the fastest reported recovery, with clinical trials showing 86% of patients achieving 20/20 vision within one week and many returning to normal activities within 24 hours. SMILE and LASIK also offer rapid recovery, with most patients seeing clearly within 1–3 days.

4. Which procedure is best for dry eyes?

SILK and SMILE are generally preferred for patients with dry eye tendencies. SILK's bi-convex lenticule design avoids the corneal nerve-dense areas more effectively, potentially resulting in the lowest dry eye risk among all options.

5. Can I have SILK if I have astigmatism?

Yes. SILK can correct astigmatism up to -6D. It also features cyclotorsion compensation for precise alignment.

6. Which surgery is best for athletes?

SILK and SMILE are excellent choices for athletes because they are flapless. There is no risk of flap displacement from trauma. SILK's tiny incision and quick recovery make it particularly appealing for contact sports participants.

7. How do I know which procedure is right for me?

The only reliable way is a comprehensive eye examination with detailed corneal mapping. Your surgeon will assess your corneal thickness, prescription, dry eye status, and lifestyle to recommend the safest and most effective option for your eyes.
