If you’re exploring laser vision correction, you’ve probably come across three acronyms that all sound promising: LASIK, PRK, and SMILE. At first glance, they might seem like different brand names for the same thing. But here’s the reality: while they all reshape your cornea to give you clearer vision, the way they get there (and how you recover afterward) is actually quite different.
You’re not alone in feeling overwhelmed by the options. Thousands of people decide to pursue vision correction every year, and many have the same questions: Which procedure is best? What’s the difference? How do I know which one is right for me?
Let’s break down what actually separates these procedures, what the research says about each one, and how to figure out which might be your best option.
What They All Have in Common
First, the reassuring part: LASIK, PRK, and SMILE are all FDA-approved laser vision correction procedures with excellent safety profiles and high success rates. They all work by reshaping your cornea so light focuses correctly on your retina, giving you clear vision without glasses or contacts.
The track record speaks for itself. Approximately 700,000 LASIK procedures are performed in the United States each year, with patient satisfaction rates consistently above 96%. These aren’t experimental treatments they’re proven, life-changing procedures backed by decades of research.
But the way each procedure achieves that correction? That’s where things get interesting.
LASIK: America’s Most Popular Choice
LASIK (Laser-Assisted In Situ Keratomileusis) has been the most commonly performed vision correction procedure in the U.S. since the FDA approved it in 1999. If you know someone who’s had laser eye surgery, chances are they had LASIK.
How It Works
A surgeon creates a thin, hinged flap on the surface of your cornea using either a microkeratome blade or, more commonly today, a femtosecond laser (that’s “bladeless LASIK”). They lift the flap, use an excimer laser to reshape the corneal tissue underneath based on your prescription, then lay the flap back down. It seals naturally without stitches.
The actual laser portion? Under 30 seconds per eye.
The Patient Experience
Most LASIK patients see 20/20 or better within 24 hours. You’ll feel pressure during the procedure but no pain thanks to numbing drops, and while you’ll need someone to drive you home immediately after, many people can drive themselves to their follow-up appointment the next day.
Recovery Timeline
- Day 1: Vision is usable, though some haziness is normal
- Week 1: Most people return to work and normal activities
- Month 1: Vision continues to sharpen and stabilize
- Months 2-3: Final results typically achieved
Who It’s Perfect For
- Patients with moderate nearsightedness, farsightedness, or astigmatism
- Anyone who needs to get back to work quickly (1-2 days)
- Those with corneas thick enough to safely create a flap
- People looking for the fastest visual recovery
The Considerations
You’ll need adequate corneal thickness for the procedure. If you play contact sports like boxing or MMA, there’s a small long-term consideration with the flap. And in the first few months after surgery, some patients experience dry eyes, though this usually resolves.
PRK: The Original That’s Still Going Strong
PRK (Photorefractive Keratectomy) actually came first. It was the first laser vision correction procedure approved by the FDA in 1995, and it remains an excellent option for many patients.
How It Works
Instead of creating a flap, the surgeon gently removes the thin outer layer of cells on your cornea (the epithelium). Then, just like with LASIK, an excimer laser reshapes the underlying tissue. A bandage contact lens is placed on your eye to protect it while the epithelium naturally regenerates over 3-5 days.
The Patient Experience
The procedure itself is quick and painless. But here’s the real difference from LASIK: recovery takes longer. You’ll experience blurry vision and discomfort for the first few days. Most patients plan to take about a week off work.
Recovery Timeline
- Days 1-3: Significant blurriness, light sensitivity, and discomfort
- Days 4-7: Vision starts clearing; bandage contact lens removed
- Weeks 2-4: Continued improvement in vision clarity
- Months 1-3: Vision fully stabilizes
Who It’s Perfect For
- Military personnel and law enforcement: PRK is approved for all branches of the U.S. military and is the preferred option for active-duty service members
- Athletes in contact sports (no flap means one less concern)
- Patients with thinner corneas who aren’t candidates for LASIK
- Anyone with certain corneal irregularities
- Those who can afford a longer recovery for long-term structural benefits
The Considerations
That first week of recovery is real you’ll need to plan accordingly. However, many eye care professionals note that PRK provides excellent long-term results without any concerns about flap complications years down the road.
SMILE: The Newest Player in Town
SMILE (Small Incision Lenticule Extraction) is the newest FDA-approved procedure. It received FDA approval in September 2016 for treating myopia and astigmatism. It’s gaining traction globally, with over 5 million procedures performed worldwide.
How It Works
This is where the technology gets really interesting. A femtosecond laser creates a tiny, lens-shaped piece of tissue (called a lenticule) inside your cornea. The surgeon then removes this lenticule through a small 2-4mm incision. No flap creation, minimal surface disruption, same refractive correction.
The Patient Experience
The procedure is quick and comfortable. Recovery sits somewhere between LASIK and PRK faster than PRK, slightly slower than LASIK. Most patients see well enough to return to work within 2-3 days.
Recovery Timeline
- Day 1: Usable vision, though blurrier than LASIK
- Days 2-3: Significant improvement
- Week 1: Most daily activities resumed
- Month 1: Vision continues stabilizing to final results
Who It’s Perfect For
- Patients with moderate to high myopia (nearsightedness)
- Anyone prone to dry eyes (SMILE preserves more corneal nerves)
- Those seeking a minimally invasive option
- Patients who want a middle ground between LASIK and PRK
The Considerations
SMILE currently only treats nearsightedness and astigmatism it can’t correct farsightedness. It’s also the newest procedure, so not every practice offers it, and surgeon experience varies. If you’re considering SMILE, make sure your surgeon has performed hundreds of procedures.
The Real Question: Which One Should YOU Choose?
Here’s what it comes down to: the “best” procedure is the one that’s best for your unique eyes, your lifestyle, and your priorities.
Choose LASIK if:
- Your corneal thickness and overall eye health allow it
- You need minimal downtime (back to work in 1-2 days)
- You want the fastest visual recovery available
- You have a moderate prescription
- You’re looking for the most established track record
Choose PRK if:
- You have thinner corneas
- You’re in the military, law enforcement, or play contact sports
- You can take a week off for recovery
- Long-term corneal stability is your top priority
- LASIK isn’t an option for anatomical reasons
Choose SMILE if:
- You’re nearsighted with or without astigmatism
- You struggle with dry eyes or are worried about them
- You want minimal tissue disruption
- Your surgeon is highly experienced with the technique
- You’re comfortable with newer (but well-proven) technology
What About Cost?
In the United States, laser vision correction is typically considered elective, which means insurance usually won’t cover it. However, many practices offer financing options, and you can often use FSA or HSA funds to pay with pre-tax dollars.
Average costs in 2025:
| Procedure Cost Per Eye |
| LASIK | $2,000-$3,000 |
| PRK | $2,000-$3,000 |
| SMILE | $2,500-$3,500 |
Remember, you’re not just paying for the procedure itself. You’re paying for the surgeon’s expertise, state-of-the-art technology, comprehensive pre-operative evaluation, follow-up care, and often lifetime enhancement policies.
Be wary of advertised prices that seem too good to be true they usually are. Many practices also accept FSA and HSA funds, which can help offset costs with pre-tax dollars.
Questions You Should Ask During Your Consultation
Don’t be shy about asking tough questions. A good surgeon will welcome them and give you honest, detailed answers. Here’s your starter list:
- How many of these procedures have you personally performed?
- What’s your complication rate?
- Do you perform all three techniques, or do you specialize in one?
- Based on my eye exam, which procedure do you recommend and why?
- What happens if I need an enhancement later?
- What exactly is included in your quoted price?
- Do you offer a lifetime enhancement policy?
Your Next Step
The truth is, you can’t make this decision from a blog post alone no matter how thorough. You need a comprehensive eye exam and consultation with an experienced refractive surgeon who can evaluate your specific eye anatomy, discuss your lifestyle needs, and recommend what’s truly best for you.
What you CAN do right now is schedule that consultation. Come armed with questions. Be honest about your lifestyle, your concerns, and your expectations. The right surgeon will listen carefully, evaluate thoroughly, and guide you toward the procedure that makes the most sense for your eyes and your life.
Vision correction surgery isn’t one-size-fits-all. But when you find the right fit? The results can be genuinely life-changing.
