- - Longer recovery is OK
LASIK
Laser-Assisted In Situ Keratomileusis
Total: $6,000-$9,000
Best for: Most patients seeking quick recovery
Pros:
- Fastest visual recovery (24-48 hrs)
- Minimal discomfort
- 30+ years proven track record
- Widely available
Cons:
- Creates 20mm corneal flap
- Not ideal for thin corneas
- Higher dry eye risk initially
- Flap complications possible (rare)
SMILE
Small Incision Lenticule Extraction
Total: $6,400-$9,000
Best for: Contact sports, military, dry eye concerns
Pros:
- Tiny 2-4mm incision (no flap)
- 80% less dry eye than LASIK
- Greater corneal stability
- Ideal for contact sports/military
Cons:
- Higher cost ($400-$1,000 more)
- Fewer clinics offer it
- Cannot correct farsightedness
- Newer procedure (10+ years)
PRK
Photorefractive Keratectomy
Total: $5,000-$7,600
Best for: Thin corneas, budget-conscious, contact sports
Pros:
- Lowest cost option
- No flap created
- Best for very thin corneas
- Long-term results identical to LASIK
Cons:
- Longer recovery (5-7 days)
- More discomfort during healing
- Bandage contact lens needed
- Vision stabilizes over weeks

Frequently Asked Questions
Which is better: LASIK, SMILE, or PRK?
There's no single 'best' procedure - it depends on your eyes and lifestyle. LASIK offers the fastest recovery and is ideal for most patients. SMILE is best for contact sports athletes, military/police, or those concerned about dry eye (80% less dry eye than LASIK). PRK is best for thin corneas or budget-conscious patients who don't mind longer recovery. All three provide excellent long-term vision outcomes.
Why is SMILE more expensive than LASIK?
SMILE requires the specialized VisuMax femtosecond laser system costing $1-1.5 million. The technology is newer and requires specific surgeon training. The extra $200-$500 per eye reflects the advanced equipment, smaller incision (2-4mm vs 20mm), and benefits like 80% less dry eye and greater corneal stability.
Why is PRK cheaper than LASIK and SMILE?
PRK is a simpler surface procedure that doesn't require the expensive equipment needed to create a corneal flap (LASIK) or lenticule (SMILE). The actual laser correction is identical. PRK costs less because it uses fewer specialized instruments, but recovery takes 5-7 days vs 24-48 hours for LASIK.
Which procedure has the best long-term results?
All three procedures have excellent long-term results when performed on suitable candidates. Studies show similar outcomes at 5-10 years. SMILE and PRK may have slight advantages in corneal stability since no flap is created. The better results come from choosing the right procedure for your eyes with an experienced surgeon.
Can I play contact sports after laser eye surgery?
SMILE is safest for contact sports - you can resume after just 1 week because of the tiny incision and no flap. PRK is also excellent for sports (1 month wait). LASIK requires 3+ months before contact sports due to the corneal flap. If you're a rugby player, boxer, or MMA fighter, SMILE or PRK is recommended.
Which procedure is best for dry eyes?
SMILE causes 80% less dry eye than LASIK because the tiny 2-4mm incision preserves more corneal nerves. PRK also has lower dry eye risk than LASIK. If you already have dry eyes or are concerned about this, SMILE is the best choice, followed by PRK. LASIK dry eye usually resolves within 3-6 months.
