SMILE vs LASIK Eye Surgery: Cost, Recovery, and How to Choose

More than 10 million eyes have now been treated with ZEISS SMILE and SMILE Pro laser vision correction worldwide, a milestone the manufacturer reported in 2024. If you wear glasses and you have started pricing laser eye surgery, you have probably run into two names: LASIK, the procedure most Americans already know, and SMILE, the newer flapless technique that clinics increasingly promote. They correct vision in different ways, they suit different eyes, and the gap in what they cost at home versus abroad is large enough to change your plans. This guide compares them honestly so you can tell which one is actually right for you.

SMILE vs LASIK at a glance

SMILE and LASIK both reshape the cornea with a laser to reduce or eliminate your need for glasses, and both routinely deliver 20/20 vision in the right candidate. The core difference is the flap. LASIK cuts a hinged flap in the surface of the cornea; SMILE works through a tiny keyhole instead. That single design choice drives most of the trade-offs in comfort, dry eye, and candidacy below.

What is SMILE, and how does it differ from LASIK?

Small Incision Lenticule Extraction (SMILE) is a flapless laser vision correction procedure. A femtosecond laser sculpts a thin, lens-shaped disc of tissue, called a lenticule, inside the cornea, and the surgeon slides it out through a keyhole opening of roughly 2 to 4 millimeters. The US Food and Drug Administration first approved SMILE for nearsightedness in 2016 and expanded it to nearsightedness with astigmatism in 2018.

LASIK reaches the same layer of tissue a different way. The surgeon creates a hinged flap across the front of the cornea, folds it back, reshapes the bed underneath with an excimer laser, and lays the flap back down. Because SMILE skips the flap and uses a much shorter incision, it disturbs fewer of the corneal nerves that regulate tear production, and it leaves more of the cornea's strong outer layer intact. In a 2019 study in the Journal of Refractive Surgery, the LASIK flap weakened 36.7% of the measured corneal biomechanical variables during surgery, compared with 13.3% for the SMILE cap. That structural advantage is the main reason surgeons often steer patients with thinner corneas or active, contact-sport lifestyles toward SMILE.

The flap is not all downside, though. Lifting it back up makes a future LASIK touch-up simple, while a SMILE enhancement usually means a surface treatment such as PRK or a converted thin-flap procedure. LASIK also treats a wider range of prescriptions and can layer in wavefront-guided customization that SMILE currently cannot.

Is SMILE safer or more comfortable than LASIK?

Neither procedure is clearly safer; both have strong long-term records in the right hands. A 2016 meta-analysis in PLOS One pooled 12 studies and 1,076 eyes and found SMILE matched femtosecond LASIK on safety, efficacy, and predictability, while showing lower rates of postoperative dry eye and loss of corneal sensitivity. LASIK's own track record is deep: a meta-analysis of nearly 68,000 eyes cited by the American Refractive Surgery Council puts patient satisfaction at 96%.

The most practical difference for most people is dry eye. Because SMILE severs fewer corneal nerves, it tends to leave eyes less dry in the first months after surgery, which matters if you already run dry or spend long days on screens. The evidence is not unanimous. A separate 2016 PLOS One dry-eye meta-analysis of 291 SMILE and 277 LASIK eyes found no significant difference in tear-film tests at later follow-ups, so the gap narrows over time. Both procedures share the same short list of risks, including undercorrection, glare or halos at night, and rare infection, which is why the clinic's accreditation and the surgeon's experience matter far more than the brand name of the laser.

Recovery is quick with either procedure. Vision clears over the first days as the cornea settles, and because SMILE heals under an intact surface rather than a lifted flap, some patients feel steady a little sooner and worry less about rubbing the eye.

How much do SMILE and LASIK cost, at home and abroad?

In the United States, SMILE usually costs a few hundred dollars more per eye than LASIK because it requires a specific ZEISS laser platform that fewer practices own. LASIK averages about $2,246 per eye in 2026 according to All About Vision, which works out to roughly $4,000 to $7,000 for both eyes, while SMILE for both eyes typically lands between $5,000 and $7,000. Neither is covered by insurance, since both are elective.

Abroad, the math changes. In Turkey, an established refractive-surgery destination, all-inclusive SMILE packages for both eyes commonly run about $2,150 to $3,450 based on 2026 clinic pricing, roughly a third less than the US average and usually bundling the diagnostics, surgery, medications, and airport transfers into one figure. The pattern mirrors what we found for LASIK cost by country, where the same accredited laser platforms cost a fraction of the US price.

Even after adding round-trip airfare, most travelers still save well over a thousand dollars, which is why cities like Istanbul have built dedicated refractive clinics around international patients. The savings only count, of course, if the care is sound, and that comes down to choosing an accredited facility rather than the cheapest quote.

Which procedure is right for you?

Start with your prescription, not the marketing. If you are farsighted, or you have astigmatism without nearsightedness, LASIK is your procedure because SMILE is not approved to treat those. If you are nearsighted, run dry, have thinner corneas, or want to avoid a flap for lifestyle reasons, SMILE is worth asking about. For a large middle group of nearsighted patients in good eye health, either works well, and the deciding factor is your surgeon's assessment of your cornea.

No article can substitute for a real evaluation. A thorough consultation measures your corneal thickness, maps its shape, and checks your tear film before anyone recommends a procedure, and a good surgeon will tell you when you are not a candidate for either.

Getting SMILE or LASIK abroad safely

If you travel for the procedure, accreditation is your anchor. JCI accreditation is an international quality certification awarded by the Joint Commission International, a US-based body that evaluates hospitals and clinics worldwide against more than 1,400 patient-safety and care-quality standards. A JCI-accredited eye clinic abroad uses the same FDA-approved laser platforms and follows the same protocols as a US practice, so the destination matters far less than the credentials.

Before you book, confirm the surgeon's refractive-surgery volume, ask how enhancements and complications are handled once you fly home, and read our guide to whether LASIK and laser surgery abroad is safe and the broader LASIK abroad pillar for how to vet a clinic. When you are ready to compare accredited options side by side, JetWell can match you to vetted eye clinics with transparent pricing.
