LASIK vs SMILE vs Contoura Vision vs PRK: Which Laser Eye Surgery Is Best?
Quick Answer
If you’re planning to get rid of glasses or contact lenses, you’ve probably come across LASIK, Contoura Vision, SMILE, and PRK. One of the most common questions patients ask is:
“Which laser eye surgery is the best?”
The honest answer is that there isn’t one procedure that’s best for everyone.
The right choice depends on factors such as:
- Your spectacle or contact lens prescription
- Corneal thickness and shape
- Presence of astigmatism
- Dry eye condition
- Lifestyle and occupation
- Long-term visual expectations
For example:
- LASIK remains one of the most established and widely performed laser vision correction procedures.
- Contoura Vision is an advanced, topography-guided form of LASIK that provides highly customised treatment for suitable patients.
- SMILE is a minimally invasive, flap-free procedure commonly recommended for myopia and myopic astigmatism.
- PRK is often preferred when corneas are thinner or flap-based surgery is not advisable.
Rather than asking which procedure is “better,” the more important question is:
Which procedure is safest and most suitable for my eyes?
A comprehensive eye examination is the only way to answer that question confidently.
Why This Comparison Matters
If you’re considering laser vision correction in Delhi, Gurgaon, Noida, Ghaziabad, Faridabad, or anywhere in Delhi NCR, you’ll quickly notice that different hospitals promote different technologies. Some advertise LASIK, while others highlight Contoura Vision or SMILE as the latest advancement.
This can leave patients wondering:
- Is Contoura better than LASIK?
- Is SMILE safer than LASIK?
- Should I choose PRK if I have thin corneas?
- Is the more expensive procedure always the better one?
The reality is that every procedure has specific indications, advantages, and limitations. The safest option for one person may not be suitable for another.
The purpose of this guide is to help you understand the differences between LASIK, Contoura Vision, SMILE, and PRK, so you can have a more informed discussion with your eye surgeon and make a confident treatment decision.
Understanding the Difference Between LASIK, Contoura Vision, SMILE and PRK
Before comparing these procedures, it’s important to understand that they are not all the same type of surgery.
LASIK
LASIK (Laser-Assisted In Situ Keratomileusis) is one of the most commonly performed laser vision correction procedures worldwide. A thin corneal flap is created, and an excimer laser reshapes the underlying cornea to correct refractive errors such as myopia, hyperopia, and astigmatism.
It has a long track record of safety, rapid visual recovery, and predictable outcomes in suitable candidates.
Contoura Vision
Contoura Vision is not a separate surgery from LASIK – it is an advanced, topography-guided version of LASIK.
Using detailed corneal mapping, Contoura creates a personalised treatment plan based on the unique shape and irregularities of your cornea. For suitable patients, this customised approach may improve visual quality beyond simply correcting spectacle power.
SMILE
SMILE (Small Incision Lenticule Extraction) is a newer, flap-free laser procedure primarily used to treat myopia and myopic astigmatism.
Instead of creating a corneal flap, a femtosecond laser creates a small disc of tissue (called a lenticule) inside the cornea, which is removed through a tiny incision. Because no flap is created, SMILE may be preferred for some patients depending on their eye condition and lifestyle.
PRK
PRK (Photorefractive Keratectomy) was the first widely adopted laser vision correction procedure and is still an excellent option for selected patients.
Unlike LASIK, PRK does not involve creating a flap. Instead, the surface layer of the cornea is gently removed before reshaping the cornea with an excimer laser.
Although visual recovery is slower, PRK remains a valuable option for patients with thinner corneas or when flap-based procedures are not recommended.
LASIK vs SMILE vs Contoura Vision vs PRK: Side-by-Side Comparison
| Feature | LASIK | Contoura Vision | SMILE | PRK |
| Procedure Type | Flap-based laser surgery | Topography-guided LASIK | Small-incision flap-free procedure | Surface laser treatment |
| Best Suited For | Common refractive errors | Suitable patients seeking customised treatment, especially with astigmatism | Myopia and myopic astigmatism | Thin corneas or when flap-based surgery is unsuitable |
| Corneal Flap | Yes | Yes | No | No |
| Level of Customisation | Standard | High | Moderate | Standard |
| Recovery | Fast | Fast | Fast | Slower |
| Return to Routine Activities | Usually within a few days | Usually within a few days | Usually within a few days | May take longer |
| Suitable for Thin Corneas | Usually not | Usually not | Depends on evaluation | Often suitable |
| Dry Eye Impact | Moderate | Moderate | Often lower in suitable patients | Temporary during healing |
| Long-Term Results | Excellent in suitable patients | Excellent in suitable patients | Excellent in suitable patients | Excellent in suitable patients |
Expert Insight
Many patients assume that the newest procedure is automatically the best. In reality, the most appropriate procedure is the one that matches your eye anatomy and visual needs. Advanced technology is valuable only when it is the right technology for your eyes.
Which Procedure Is Right for You?
Choosing laser eye surgery isn’t about selecting the most advertised procedure – it’s about selecting the one that offers the best balance of safety, visual quality, and long-term stability.
The table below provides general guidance.
| Your Situation | Procedure Often Considered |
| Healthy corneas with common refractive errors | LASIK |
| Significant astigmatism and desire for customised treatment | Contoura Vision |
| Moderate to high myopia and preference for a flap-free procedure | SMILE |
| Thin corneas | PRK |
| High-impact sports or occupations where flap-related concerns are relevant | PRK |
| Myopia with myopic astigmatism | SMILE |
| Desire for highly customised laser correction | Contoura Vision |
Important: This table is intended as general guidance. The final recommendation depends on your eye examination, corneal measurements, and overall eye health.
Who Is Eligible for Laser Eye Surgery?
Most patients considering laser vision correction share one concern:
“Am I eligible?”
While eligibility varies between procedures, the following criteria generally apply.
You may be a suitable candidate if you:
- Are at least 18 years old
- Have had a stable spectacle or contact lens prescription for at least one year
- Have healthy eyes with no active infection or inflammation
- Have sufficient corneal thickness for the chosen procedure
- Have realistic expectations regarding outcomes
Laser vision correction may not be recommended if you have:
- Progressive keratoconus or other corneal disorders
- Severe uncontrolled dry eye
- Pregnancy or breastfeeding (temporary postponement)
- Uncontrolled diabetes affecting healing
- Certain autoimmune conditions
- Rapidly changing spectacle power
Eligibility should always be determined after a detailed eye examination rather than based on age or spectacle number alone.
How Eye Surgeons Decide Which Procedure Is Best
One of the biggest misconceptions is that patients can simply choose the procedure they prefer.
In reality, your eyes choose the procedure.
A comprehensive refractive surgery evaluation helps determine which option is safest and most effective by assessing:
- Corneal thickness
- Corneal shape
- Refractive error
- Tear film quality
- Eye pressure
- Retinal health
- Pupil size
- Lifestyle and occupational requirements
These findings help your surgeon recommend the procedure that provides the best long-term visual outcome while minimising potential risks.
What Tests Are Performed Before Laser Eye Surgery?
Before recommending LASIK, Contoura Vision, SMILE, or PRK, your ophthalmologist may perform several diagnostic tests, including:
- Comprehensive eye examination
- Refraction (spectacle power assessment)
- Corneal topography
- Corneal tomography
- Pachymetry (corneal thickness measurement)
- Tear film and dry eye assessment
- Intraocular pressure measurement
- Dilated retinal examination
- Wavefront analysis, where appropriate
Each test provides valuable information about your eye health and helps determine whether laser vision correction is appropriate and which procedure is likely to provide the best outcome.
Laser Eye Surgery in Delhi NCR: Why Personalised Evaluation Matters
Patients from Delhi, Gurgaon, Noida, Ghaziabad, Faridabad, and neighbouring cities often compare hospitals based on technology or price alone. While these factors are important, the quality of the pre-operative evaluation is equally critical.
A centre that offers multiple procedures – rather than promoting only one – can recommend the treatment that best matches your eye health instead of fitting every patient into the same approach.
At Mohan Eye Institute, the focus is on personalised treatment planning. Every recommendation is based on detailed diagnostic testing, clinical findings, and your visual needs, ensuring that the chosen procedure prioritises long-term safety and visual outcomes.
Recovery Comparison: LASIK vs SMILE vs Contoura Vision vs PRK
One of the biggest factors influencing a patient’s decision is how quickly they can return to work, drive, use digital screens, or resume their normal lifestyle. Although all four procedures aim to reduce dependence on glasses or contact lenses, the recovery experience is different.
Recovery Timeline Comparison
| Recovery Stage | LASIK | Contoura Vision | SMILE | PRK |
| Procedure Duration | 10–20 minutes (both eyes) | 10–20 minutes (both eyes) | 15–20 minutes (both eyes) | 15–20 minutes (both eyes) |
| Initial Vision Improvement | Usually within 24 hours | Usually within 24 hours | Usually within 24–48 hours | Gradual over several days |
| Mild Discomfort | Few hours | Few hours | Few hours | 2–4 days |
| Return to Office Work | 1–2 days | 1–2 days | 1–2 days | Around 5–7 days |
| Driving | Usually next day (if vision allows) | Usually next day | Usually next day | After adequate vision recovery |
| Gym & Light Exercise | About 1 week | About 1 week | About 1 week | 2–4 weeks |
| Swimming | After surgeon’s advice | After surgeon’s advice | After surgeon’s advice | After surgeon’s advice |
| Vision Stabilisation | Few weeks | Few weeks | Few weeks | Several weeks to months |
Expert Insight: Recovery speed should not be the only factor in choosing a procedure. A slightly longer recovery with PRK may still be the safest option for patients with thinner corneas or specific clinical considerations.
Is Laser Eye Surgery Painful?
This is one of the most frequently asked questions.
The procedures themselves are generally not painful because anaesthetic eye drops are used before surgery.
However, the recovery experience differs:
- LASIK: Mild irritation or watering for a few hours.
- Contoura Vision: Similar to LASIK, with mild temporary discomfort.
- SMILE: Usually mild irritation and foreign body sensation initially.
- PRK: More noticeable discomfort during the first few days while the surface layer heals.
Most patients describe the experience as manageable with prescribed eye drops and medications.
Which Procedure Is the Safest?
There is no universally safest procedure.
Each surgery has an excellent safety profile when performed on the right patient after appropriate screening.
The safest procedure is the one recommended after evaluating:
- Corneal thickness
- Corneal shape
- Refractive error
- Tear film quality
- Pupil size
- Lifestyle
- General eye health
For example:
- A patient with healthy corneas may be an excellent candidate for LASIK or Contoura Vision.
- Someone with thinner corneas may achieve a safer outcome with PRK.
- A patient looking for a flap-free option may be suitable for SMILE.
The goal is not to fit every patient into one technology but to match the technology to the patient’s eyes.
Risks and Possible Complications
Like any surgical procedure, laser vision correction carries some risks. Fortunately, serious complications are uncommon when patients are carefully selected and follow post-operative instructions.
Common Temporary Side Effects
- Dry eye symptoms
- Glare around lights at night
- Halos
- Light sensitivity
- Fluctuating vision during healing
These usually improve over time.
Less Common Complications
- Infection
- Under-correction or over-correction
- Delayed healing (more common with PRK)
- Corneal ectasia in susceptible eyes
- Need for enhancement surgery in selected cases
Careful pre-operative testing helps reduce these risks significantly.
How Much Does Laser Eye Surgery Cost in Delhi NCR?
Patients often compare hospitals based only on price. However, the lowest advertised package may not include everything you need.
The total cost can vary depending on:
- The procedure selected (LASIK, Contoura Vision, SMILE, or PRK)
- Diagnostic investigations
- Technology used
- Surgeon’s experience
- Medicines
- Follow-up visits
- Enhancement policy
- Financing or EMI options
Relative Cost Comparison
| Procedure | Estimated Price (Both Eyes)* | Why It May Cost More |
| PRK | ₹70,000 to ₹1,00,000* | Longer follow-up and recovery, but simpler technology |
| LASIK | ₹80,000 to ₹1,60,000* | Standard laser vision correction |
| Contoura Vision | ₹70,000 to ₹1,50,000* | Advanced topography-guided planning |
| SMILE | ₹80,000 to ₹1,80,000* | Advanced femtosecond laser technology |
*Costs vary between hospitals and should always be confirmed during your consultation.
Patient Tip: Instead of asking, “Which surgery is cheapest?”, ask, “What does the package include?” A transparent treatment plan should cover diagnostics, surgery, medications, follow-up care, and any enhancement policy.
How to Choose the Right Eye Hospital in Delhi NCR
If you are comparing eye hospitals in Delhi, Gurgaon, Noida, Ghaziabad, Faridabad, or nearby areas, choosing the right hospital is just as important as choosing the right procedure.
Here are some factors to consider:
1. Does the Hospital Offer Multiple Procedures?
A hospital that provides LASIK, Contoura Vision, SMILE, and PRK can recommend the procedure best suited to your eyes rather than promoting only one technology.
2. Is a Comprehensive Evaluation Performed?
The consultation should include detailed corneal imaging, dry eye assessment, and retinal examination – not just a spectacle power check.
3. What Is the Surgeon’s Experience?
Experience with refractive surgery and patient selection is a key factor in achieving safe, predictable outcomes.
4. Is the Technology Up to Date?
Modern diagnostic equipment helps identify patients who may benefit from customised treatment or who should avoid certain procedures.

Frequently Asked Questions
Which laser eye surgery is best?
There is no single best procedure. The right option depends on your prescription, corneal thickness, eye health, lifestyle, and clinical evaluation.
Is Contoura Vision better than LASIK?
Contoura Vision is an advanced form of LASIK that uses detailed corneal mapping to personalise treatment. It may offer advantages for suitable patients, but it is not automatically the best choice for everyone.
Is SMILE safer than LASIK?
SMILE is a flap-free procedure and may be preferred for certain patients. However, both SMILE and LASIK have excellent safety records when performed on appropriate candidates.
Can I have laser eye surgery if I have thin corneas?
Some patients with thinner corneas may still be suitable for PRK or, in selected cases, SMILE. A detailed corneal evaluation is required before making a recommendation.
Which procedure has the fastest recovery?
LASIK, Contoura Vision, and SMILE generally provide faster visual recovery than PRK. However, recovery speed should not outweigh long-term safety.
Which procedure causes less dry eye?
Dry eye symptoms vary from person to person. Some studies suggest that SMILE may be associated with fewer dry eye symptoms in suitable patients, but the best option depends on your eye condition.
Can laser eye surgery permanently remove glasses?
Laser vision correction provides long-term correction for stable refractive errors. However, natural age-related changes, such as presbyopia, can still occur later in life.
How long do the results last?
The corneal reshaping performed during laser vision correction is permanent. If your prescription is stable before surgery, the correction is generally long-lasting, although age-related vision changes may still occur.
Is laser eye surgery suitable for high myopia?
Many patients with moderate to high myopia can be treated successfully. The most suitable procedure depends on the degree of myopia, corneal thickness, and overall eye health.
How long does the entire evaluation take?
A comprehensive refractive surgery assessment typically takes 60–90 minutes, depending on the tests required.
Final Thoughts: Which Laser Eye Surgery Should You Choose?
If you’ve reached this point, you’ve probably realised that the answer isn’t as simple as choosing the latest technology or the most advertised procedure.
The best laser eye surgery is the one that offers the safest, most predictable outcome for your individual eyes.
- LASIK remains a trusted option for many suitable candidates.
- Contoura Vision provides highly personalised treatment for selected patients.
- SMILE offers a flap-free approach for appropriate cases of myopia and myopic astigmatism.
- PRK continues to play an important role for patients with thinner corneas or when flap-based procedures are not advisable.
The final recommendation should always be based on a detailed eye examination rather than preference alone.
