LASIK vs SMILE Eye Surgery
Both LASIK and SMILE deliver permanent refractive correction. LASIK has 25+ years of clinical use, broad FDA-approval coverage (myopia, hyperopia, astigmatism, presbyopia), and faster visual recovery. SMILE is newer in the US (FDA-approved 2016), is flapless (which reduces dry eye risk and flap-related complications), and is currently approved for myopia and astigmatism only.
At a Glance
| Dimension | LASIK Eye Surgery | smile-eye-surgery |
|---|---|---|
| Procedure type | Flap-based; femtosecond + excimer laser | Flapless; femtosecond laser only |
| Median cost per eye | $2,600 | $3,000 |
| FDA approval scope | Myopia, hyperopia, astigmatism, presbyopia (LASIK PresbyLASIK) | Myopia and astigmatism only (as of 2026) |
| Recovery time to functional vision | 24-48 hours | 24-72 hours |
| Dry eye incidence at 6 months | 10-30% report symptoms | 5-15% (lower due to fewer corneal nerves cut) |
| Flap-related complication risk | Low (less than 0.5%) but exists | None (flapless) |
| Suitability for athletes / military | Acceptable; some military branches prefer SMILE or PRK | Often preferred due to flapless construction |
| Approved laser platforms | Multiple (Alcon WaveLight, Bausch + Lomb, etc.) | Zeiss VisuMax only |
| Treatment range (myopia) | Up to -12.00 D | Up to -10.00 D |
| Treatment range (astigmatism) | Up to -6.00 D | Up to -3.00 D |
About this comparison
LASIK and SMILE are the two most-performed laser refractive procedures in the United States. LASIK uses a femtosecond laser to create a corneal flap and an excimer laser to reshape the underlying cornea. SMILE (Small Incision Lenticule Extraction) uses only a femtosecond laser to create a small lenticule of corneal tissue that is removed through a tiny incision, leaving no corneal flap.
Patients with hyperopia (farsightedness), patients with high astigmatism (over 3 D), patients with presbyopia interested in PresbyLASIK, patients prioritizing fastest visual recovery, and patients with prescriptions beyond the SMILE FDA-approved range. LASIK is also more broadly available since multiple laser platforms are FDA-approved.
Patients with significant dry eye risk or concerns about dry eye, athletes or military candidates concerned about flap complications, patients prioritizing the flapless construction for sports impact resistance, and patients with prescriptions within the SMILE FDA-approved range.
Cost comparison
SMILE typically costs $300-$600 more per eye than standard LASIK in the United States, reflecting the newer Zeiss VisuMax technology and surgeon training requirements. Total per-eye pricing in 2026 averages $2,600 for LASIK and $3,000 for SMILE. Both eyes typically run $5,200 (LASIK) vs $6,000 (SMILE).
Evidence comparison
LASIK has 25+ years of clinical evidence with extensive long-term outcome data showing 90-95% of patients maintain 20/40 or better vision at 10 years. SMILE has fewer years of US data (FDA-approved 2016) but international studies from Europe and Asia show similar visual outcomes, fewer dry eye symptoms, and lower flap-related complication risk.
Frequently asked questions
Which is better, LASIK or SMILE? +
Neither is universally better. LASIK offers faster visual recovery, broader FDA-approved indications (including hyperopia and presbyopia), and lower cost. SMILE offers a flapless approach with lower dry eye risk and no flap complication risk, preferred for athletes and military candidates. Choice depends on prescription, dry eye risk, and lifestyle.
How much more does SMILE cost than LASIK? +
SMILE typically costs $300-$600 more per eye than standard LASIK ($3,000 vs $2,600 median in the United States). Total cost difference for both eyes is $600-$1,200.
Is SMILE safer than LASIK? +
SMILE eliminates flap-related complications because no flap is created. It also typically results in less dry eye because fewer corneal nerves are severed. However, overall complication rates for both procedures are very low (under 1% for serious complications). For most healthy candidates, both procedures are considered safe.
Can SMILE correct farsightedness? +
Not currently. As of 2026, SMILE is FDA-approved only for myopia (nearsightedness) and astigmatism. Hyperopia (farsightedness) requires LASIK or PRK. SMILE for hyperopia is in clinical development internationally.
Which has less dry eye risk, LASIK or SMILE? +
SMILE has approximately half the dry eye incidence of LASIK in published studies. At 6 months post-procedure, roughly 5-15% of SMILE patients report dry eye symptoms versus 10-30% of LASIK patients. The flapless construction preserves more corneal nerve density, which reduces dry eye risk.
How long do LASIK and SMILE last? +
Both procedures provide permanent refractive correction. The underlying corneal reshaping is permanent. However, age-related vision changes (presbyopia after age 40, cataracts later) still occur and may require reading glasses or future intervention.
Can I get SMILE if I have high astigmatism? +
SMILE is FDA-approved for astigmatism up to -3.00 D. Higher astigmatism requires LASIK (approved to -6.00 D) or alternative procedures like ICL.
Bottom line
For most healthy candidates with myopia and low-to-moderate astigmatism, both procedures deliver excellent results. SMILE is preferred for athletes, military candidates, and patients with dry eye concerns. LASIK is preferred for patients with hyperopia, higher astigmatism, presbyopia interest, fastest recovery preference, or budget consciousness. A consultation with corneal topography determines candidacy for either procedure.
