Different Types of Laser Eye Surgery: Which One is Right for You?

What Is Laser Eye Surgery — And How Has It Changed?

If you’ve spent years struggling to see clearly—squinting at the board, reaching for your glasses, or dealing with dry contact lenses—you’ve probably wondered: can laser surgery actually fix this?

The short answer is yes — for most people, it can fix.

Laser eye surgery uses focused beams of light to reshape the cornea (the clear front surface of your eye), correcting how light enters and focuses. The result? Clear, sharp vision — often without glasses or contacts.

But here’s what many people don’t know: laser eye surgery isn’t just one procedure. It’s a family of techniques, and the one that’s right for you depends on your eye shape, corneal thickness, lifestyle, and vision prescription.

The field has evolved dramatically. In the 1980s, PRK was the only option. LASIK arrived in the 1990s and became the gold standard. Then came SMILE, and now SILK — the world’s newest flapless laser procedure. Alongside these, Contoura Vision brought topography-guided precision that no earlier generation of surgery could match.

This guide walks you through every major type of laser eye surgery available today — in plain language — so you can have an informed conversation with your doctor and make the right choice for your vision.

Types of Laser Eye Surgery

There are several types of laser eye surgery, each with its own technique, recovery timeline, and ideal candidate profile. Here’s a complete breakdown.

PRK (Photorefractive Keratectomy) / ASA — The Original

Best for: Thin corneas, active lifestyles, contact sport players

PRK was the first laser eye surgery ever performed, and it’s still widely used today — not because nothing better came along, but because it genuinely suits certain patients better than newer methods.

In PRK, the surgeon removes the thin outer layer of the cornea (the epithelium) entirely before reshaping the tissue underneath with a laser. The epithelium heals and grows back on its own within a few days.

What makes it different:

• No flap is created — making it safer for people with thinner-than-average corneas
• Well-suited for people who play contact sports or have physically demanding jobs, where a flap could theoretically be dislodged
• Results are identical to LASIK once fully healed

The tradeoff: Recovery is slower. Your vision will be blurry for 3–7 days while the epithelium heals, and it can take up to a month to reach your final visual sharpness. Most patients experience some discomfort in the first few days.

ASA (Advanced Surface Ablation) is simply the modern, refined version of PRK — same concept, better technique.

LASIK

Best for: Most adults with myopia, hyperopia, or astigmatism; adequate corneal thickness

LASIK is the most popular laser eye surgery—and for good reason. It gives quick results with very little discomfort.

Here’s how it works: A surgeon creates a thin flap on the cornea, gently lifts it, reshapes the underlying tissue with a laser, and then places the flap back. It heals naturally—no stitches needed.

Why people love it:

• Vision improvement is often dramatic within 24 hours
• The procedure itself takes about 15 minutes per eye
• Minimal pain during or after surgery
• Proven track record over 30+ years and tens of millions of procedures worldwide

Who may not be suitable:

• Thin corneas (the flap creation removes tissue)
• Very high prescriptions
• Dry eye conditions
• Irregular corneal shape

Femto-LASIK (Bladeless LASIK)

Best for: Patients wanting LASIK with greater precision and no blade

Femto-LASIK is LASIK — but instead of a blade, the surgeon uses a femtosecond laser to create the corneal flap. This makes the procedure entirely bladeless.

The femtosecond laser creates an extraordinarily thin, precise flap (measured in microns), which leaves more corneal tissue intact and reduces the risk of flap-related complications.

Why it’s better than traditional LASIK:

• More precise flap creation = lower risk of complications
• Customisable flap thickness and diameter
• Safer for patients with slightly thinner corneas who might not qualify for standard LASIK
• Better outcomes for patients with astigmatism

In most quality eye hospitals in India today, Femto-LASIK has replaced traditional blade LASIK as the standard of care.

LASEK & Epi-LASIK

Best for: Patients who don’t qualify for LASIK but want faster recovery than PRK

LASEK (Laser Epithelial Keratomileusis) and Epi-LASIK sit between PRK and LASIK. Instead of removing the epithelium entirely (as in PRK) or creating a deep flap (as in LASIK), they preserve the epithelial layer and move it aside temporarily.

In LASEK, the epithelium is loosened with an alcohol solution and pushed back. In Epi-LASIK, a plastic separator is used instead of alcohol, making it slightly gentler on cells.

Honest assessment: These procedures were more popular before SMILE arrived. They offered a compromise, but recovery was still slower than LASIK and results weren’t dramatically better. Today, most surgeons prefer PRK over LASEK for surface procedures. However, they remain a valid option in specific clinical situations.

SMILE (Small Incision Lenticule Extraction)

Best for: People with dry eyes, thinner corneas, active lifestyles, high myopia

SMILE is one of the most significant advances in laser vision correction in the last decade. Unlike LASIK, it doesn’t create a flap at all.

Here’s what happens: A femtosecond laser creates a tiny lens-shaped piece of tissue (called a lenticule) inside the cornea. The surgeon then removes this lenticule through a small 2–4 mm keyhole incision. By removing this tissue, the corneal shape changes — and vision is corrected.

Why it’s a game-changer:

• No flap = no risk of flap dislodgement (great for athletes and physically active people)
• Preserves more corneal nerve fibres = significantly less post-operative dry eye
• Only one laser is used throughout (simpler, faster procedure)
• Suitable for higher levels of myopia than LASIK in some cases

The tradeoff: SMILE currently corrects myopia (short-sightedness) and astigmatism, but has limited use for hyperopia (long-sightedness). Recovery is slightly slower than LASIK — most patients see clearly within 1–3 days, with full stabilisation over a few weeks.

SILK (Smooth Incision Lenticule Keratomileusis)

Best for: Patients seeking the latest technology; similar profile to SMILE candidates

SILK is the newest type of laser eye surgery available, launched in India in 2023. It works on the same principle as SMILE — removing a lenticule from inside the cornea through a small incision — but uses a newer generation femtosecond laser (the ELITA platform) that operates at a higher pulse frequency.

What makes SILK different from SMILE:

• Faster laser delivery — the procedure is quicker
• Smoother lenticule surface, which may improve optical quality
• Smaller incision (approximately 2 mm vs 2–4 mm in SMILE)
• Even less disruption to corneal nerves

Important to know: SILK is still accumulating long-term outcome data. The technology is promising and early results are excellent, but it has fewer years of data behind it compared to SMILE or LASIK. Discuss this honestly with your surgeon before choosing it.

Contoura Vision (Topography-Guided LASIK)

Best for: Patients with irregular corneas, higher-order aberrations, or those seeking the sharpest possible vision quality

Contoura Vision is not a separate procedure in the way SMILE or PRK are — it’s a form of LASIK, but with a crucial difference: it uses corneal topography mapping to create a completely personalised treatment plan for each eye.

Standard LASIK corrects your glasses prescription. Contoura Vision corrects your prescription and the unique imperfections in your corneal surface — up to 22,000 data points are mapped per eye.

Why it matters: Many patients who were already corrected to 6/6 (or 20/20) with glasses find that Contoura Vision gives them better vision than their glasses ever did. This is because it addresses irregularities that glasses cannot correct.

Ideal for:

• Patients with higher-order aberrations (glare, halos, starbursts around lights)
• Those with irregular astigmatism
• People seeking “super vision” outcomes
• Patients who had previous unsuccessful refractive surgery

Limitations: Contoura Vision requires adequate corneal thickness (as it’s flap-based). It also costs more than standard LASIK due to the advanced mapping technology involved.

Laser Eye Surgery Cost in India (2026 Price Guide)

Costs vary significantly depending on the procedure, the technology used, the surgeon’s experience, and the city. Here’s a general range to help you plan:

Note: These are indicative ranges for 2026. Final pricing depends on your pre-operative evaluation, the centre you choose, and any post-operative care included. Always ask for an all-inclusive quote — make sure it covers pre-op testing, the procedure, medications, and follow-up visits.

Is the cheapest option the right choice? Not always. The most important factors are your surgeon’s experience, the quality of equipment, and whether the recommended procedure genuinely suits your eyes. A more expensive, better-suited procedure often delivers better long-term outcomes than a cheaper one that isn’t ideal for your eye profile.

Risks & Safety: What to Know Before Choosing Lasik Surgery

Laser eye surgery is one of the safest elective surgeries performed globally, with a satisfaction rate consistently above 95%. But like any medical procedure, it carries risks you should understand before proceeding.

Common, temporary side effects:

• Dry eyes (usually resolves within 3–6 months)
• Glare, halos or starbursts around lights at night (most common in the first few weeks)
• Fluctuating vision during the healing period
• Mild discomfort or a gritty sensation in the eye

Less common risks:

• Under-correction or over-correction (may require a touch-up procedure)
• Regression over time (vision gradually drifts; more common with high prescriptions)
• Flap complications (specific to flap-based procedures like LASIK)
• Infection (rare, but possible with any eye surgery)

Who should NOT have laser eye surgery:

• Patients under 18 (prescription still changing)
• Pregnant or breastfeeding women
• Those with keratoconus (a condition that weakens the cornea)
• People with certain autoimmune conditions
• Patients with extremely thin corneas (depending on procedure)

The best way to determine your personal risk profile is through a thorough pre-operative evaluation — which any reputable eye hospital will perform before recommending any procedure.

How to Choose the Right Type of Laser Eye Surgery for Your Eyes

There is no single “best” laser eye surgery — only the best one for your eyes. Here’s how to think through it:

• Start with your corneal thickness. This is the single most important factor. If your corneas are thin, flap-based procedures (LASIK, Contoura) may not be suitable. Your doctor will measure this during the pre-op exam.
• Consider your prescription range. Very high myopia may be better suited to SMILE or PRK than standard LASIK. Hyperopia is currently best corrected with LASIK-based procedures.
• Think about your lifestyle. Do you play contact sports? Work in dusty environments? SMILE or SILK (flapless procedures) eliminate the risk of flap disruption. If you experience significant dry eyes with contacts, flapless options also preserve more corneal nerves.
• Ask about your corneal irregularities. If your cornea has surface irregularities beyond your standard prescription, Contoura Vision may deliver meaningfully better results than standard LASIK.
• Consider recovery time. If you need to return to work quickly, LASIK-based procedures offer the fastest visual recovery (often within a day). PRK requires the longest recovery.
• Get a full pre-operative evaluation. No article — including this one — can tell you which procedure is right for you. A proper corneal topography scan, pachymetry (corneal thickness measurement), dry eye assessment, and pupil size evaluation are essential. Most reputable eye centres offer this assessment as a first step.
