SMILE vs. LASIK: Which Vision Correction Option Is Right for You?
If you are researching laser vision correction in Detroit or anywhere across Michigan, you have likely come across two leading technologies: SMILE and Wavelight LASIK. Both procedures are designed to reduce dependence on glasses and contact lenses, but they work in different ways and are suited to different types of patients.
At Fraser Eye Care, our approach is centered on recommending the most precise, predictable, and personalized vision correction option for your eyes. While SMILE is one of several modern techniques you may encounter in your research, our focus is on advanced, data-driven technologies, like Wavelight LASIK that allow for a higher level of customization and a broader range of treatment.

Quick Comparison: SMILE vs. Wavelight LASIK
If you are looking for a high-level overview, here is how the two procedures typically compare:
- Wavelight LASIK is often preferred for patients seeking highly personalized treatment and the sharpest possible visual outcomes
- SMILE may appeal to patients who prefer a flapless procedure or have specific dry eye concerns
- Wavelight LASIK can treat a broader range of prescriptions, including farsightedness
- SMILE is limited to nearsightedness and astigmatism
The right choice ultimately depends on your eye anatomy, prescription, and visual goals.
What Is SMILE?
SMILE (Small Incision Lenticule Extraction) is a minimally invasive, flapless laser vision correction procedure used to treat nearsightedness (myopia) and astigmatism.
During the procedure, a femtosecond laser creates a small disc of tissue (called a lenticule) within the cornea. This lenticule is then removed through a tiny incision, reshaping the cornea and improving vision.
Key features of SMILE:
- Flapless procedure with a small incision (approximately 2–4 mm)
- Uses a single femtosecond laser
- Often considered for patients concerned about flap-related complications
- May result in fewer dry eye symptoms for some patients
- Limited to treating myopia and astigmatism
- Visual recovery may be slightly more gradual in some cases
Because SMILE follows a more standardized treatment approach, it may not offer the same level of customization as newer LASIK technologies.
What Is Wavelight LASIK?
Wavelight LASIK is an advanced form of laser vision correction that uses a highly personalized, data-driven approach to treatment planning.
At Fraser Eye Care, LASIK is performed using the Wavelight Plus platform with SightMap-guided planning. This system creates a detailed 3D model of your eye using ray-tracing technology, allowing your surgeon to customize treatment based on the unique optical characteristics of your eye.
The procedure involves creating a thin corneal flap, followed by precise reshaping of the underlying tissue with an excimer laser.
Key features of Wavelight LASIK:
- Ray-tracing–guided treatment based on a 3D model of your eye
- Highly personalized correction using thousands of data points
- Two-laser system for precision and control
- Rapid visual recovery, often within 24 hours
- Treats myopia, hyperopia, and astigmatism
- Designed to reduce higher-order aberrations and improve visual quality
SMILE vs. Wavelight LASIK: Side-by-Side Comparison
| Feature | SMILE | WaveLight LASIK |
|---|---|---|
| Procedure Type | Flapless lenticule extraction | Flap-based corneal reshaping |
| Lasers Used | Femtosecond only | Femtosecond + excimer |
| Incision Size | Small (2–4 mm) | Corneal flap (~20 mm arc) |
| Conditions Treated | Myopia, astigmatism | Myopia, hyperopia, astigmatism |
| Visual Recovery | Gradual (days to weeks) | Rapid (often within 24 hours) |
| Customization | Moderate | Highly personalized (ray-tracing guided) |
| Dry Eye Considerations | May be reduced in some patients | Minimal with modern techniques |
| Enhancement Options | Often requires LASIK/PRK | Straightforward enhancement options |
What the Latest Research Shows
Recent data presented at the 2025 American Academy of Ophthalmology Annual Meeting compared Wavelight Plus LASIK and SMILE Pro in the same patients—one eye treated with each procedure.
The findings highlighted meaningful differences in visual outcomes:
- 98% of Wavelight Plus patients achieved 20/12.5 vision or better, compared to 82% with SMILE Pro
- A higher percentage of Wavelight patients achieved outcomes within a very narrow margin of their target prescription
- Wavelight LASIK demonstrated improved contrast sensitivity and reduced optical imperfections1
For patients, this level of precision can translate to sharper vision, improved night vision, and greater overall visual clarity.
These differences are largely attributed to the advanced planning capabilities of Wavelight technology, which uses detailed eye mapping and ray-tracing to create a highly individualized treatment plan.
Why Personalization Matters in Vision Correction
One of the biggest differences between SMILE and LASIK with Wavesight is the level of customization.
LASIK with Wavelight uses advanced mapping and analytics to guide treatment, helping address not only refractive error but also subtle optical imperfections that can affect visual quality, such as glare, halos, and reduced contrast sensitivity.
This approach may be especially beneficial for:
- Patients seeking the clearest possible vision
- Individuals with more complex prescriptions
- Patients concerned about night vision or visual quality
SMILE, while effective, follows a more standardized treatment approach and does not offer the same level of customization.
Who Is a Candidate for Each Procedure?
Both procedures require a comprehensive eye exam and diagnostic evaluation.
LASIK with Wavelight may be recommended if you:
- Have myopia, hyperopia, or astigmatism
- Want a highly customized treatment approach
- Are looking for rapid visual recovery
- Have a prescription within treatable ranges
SMILE may be considered if you:
- Have moderate to high myopia
- Prefer a flapless procedure
- Have specific concerns about dry eye
- Do not require correction for farsightedness (hyperopia)
At Fraser Eye Care, candidacy is determined through detailed testing and consultation to ensure the safest and most effective treatment plan.
Which Is Better: SMILE or LASIK with Wavelight?
There is no one-size-fits-all answer, but there are clear differences that may help guide your decision.
- For the most precise, customized results: LASIK with Wavelight
- For a flapless approach: SMILE
- For treating a wider range of prescriptions: LASIK with Wavelight
- For patients prioritizing advanced technology and personalization: LASIK with Wavelight
For many patients, the ability to customize treatment at a highly detailed level is a key factor in achieving optimal visual outcomes. However, the right procedure ultimately depends on your individual anatomy, lifestyle, and vision goals.
Some patients also prefer a flapless approach for lifestyle or occupational reasons — including pilots, law enforcement officers, and contact sport athletes, for whom the absence of a corneal flap reduces the risk of flap displacement from physical impact.

Fraser is by far your best option if you're looking for a place to get Lasik. I recently had my procedure done, and it went really well from beginning to end. They are very accommodating, and their communication and facility are in excellent condition. Although I was previously skeptical about the Lasik procedure, I was really happy. Overall, recovery was very quick, and I was able to see about 90% the following day. All of the nurses and doctors are amazing. They know how to take care of you.Fares Y., Google Review
