Quick answer
SMILE Pro and LASIK both change the shape of the cornea to correct short sightedness and astigmatism. SMILE Pro removes a lenticule through a small incision and creates no flap; LASIK creates a hinged flap and reshapes the cornea underneath it. The decision between them is made from your measurements, not from which technology is newer.

Both reshape the cornea and both correct short-sightedness and astigmatism. The difference that everything else flows from is that LASIK lifts a flap and SMILE does not.
| Category | SMILE Pro | LASIK |
|---|---|---|
| Access to the tissue | A small incision, with the outer corneal surface left largely intact | A hinged flap is cut, folded back, and repositioned at the end |
| Laser used | A single femtosecond laser performs the whole procedure | A femtosecond or mechanical device creates the flap, then an excimer laser reshapes the cornea |
| Corneal nerves | Fewer nerves are cut because the incision is small, which is why dry-eye measures often look better early on | A flap cuts across more of the nerve network, which is why dryness is a well-documented early feature |
| If a further procedure is needed | No flap exists, so enhancement requires a different approach, sometimes a surface treatment | The existing flap can often simply be lifted and the cornea re-treated |
| Prescriptions | Established for short-sightedness and myopic astigmatism | Broader range, including long-sightedness |
Your surgeon judges that a small-incision approach suits your cornea and tear film, and no flap-free access is a specific advantage for you: for example where dry eye or a lifestyle with impact risk is a consideration.
You need a prescription corrected that lenticule extraction does not routinely treat, or the surgeon believes the ability to lift a flap later for an enhancement is a meaningful advantage in your case.
Neither column is a recommendation. Which procedure suits you depends on measurements that can only be taken in a clinic, and a surgeon who tells you one option is right for everyone is describing their product, not your eyes.
SMILE Pro vs LASIK
SMILE Pro is the newer generation of the lenticule platform, and the word Pro refers to that platform rather than to a different operation. As with the earlier generation, a femtosecond laser creates a disc of tissue inside the cornea and the surgeon removes it through a small incision, with no flap at any point.
LASIK is the older and far more widely performed answer to the same problem: a flap is cut in the surface layer, folded back, and an excimer laser reshapes the exposed tissue before the flap is laid back down. The comparison between the two is therefore almost entirely the comparison between having a flap and not having one.
Where the difference really sits
The platform generation changes how the lenticule is created: a newer laser applies the pulses faster, which shortens the time the eye is under suction and is why clinics advertise it. It does not change the fact that no flap is created, which is the difference a patient lives with for decades rather than for the length of the procedure.
Equally, "LASIK" is not one procedure. A laser-created flap and a mechanically created flap are both called LASIK by many clinics, and the two have different risk profiles. When a clinic compares its lenticule platform with LASIK, it is usually comparing with the laser-flap version, and it is worth asking which one they mean.
What the flap changes afterwards
A flap interrupts more of the corneal nerves that keep the surface moist, and it leaves an interface between the flap and the tissue beneath it. That interface is stable in the overwhelming majority of eyes, and it is the reason for two of the restrictions after LASIK: do not rub the eye, and take care with contact sports in the early weeks.
It is also the reason an enhancement is easier after LASIK. A residual prescription can often be treated by lifting the existing flap, which is quicker and gentler than any alternative. After lenticule extraction there is nothing to lift, so a refinement means a surface treatment.
Prescriptions, honestly
Lenticule extraction was developed for short sightedness and myopic astigmatism, and that remains its established ground. LASIK covers a wider range, including long sightedness, mixed astigmatism and higher corrections where the cornea can spare the tissue. For a long-sighted prescription, the realistic comparison is LASIK against a surface procedure, not against a lenticule platform.
If your prescription sits comfortably inside what both techniques treat, the deciding factors are your corneal thickness and shape, your tear film, your occupation and hobbies, and your surgeon's own experience with each. Those are clinical judgements, made from measurements and from a conversation, which is why no page can settle the question for your eye.
What it costs, and what to compare
Lenticule platforms are newer and more expensive to run, and clinics in Dubai price them accordingly, but the gap between a lenticule quote and a LASIK quote varies enormously between clinics and is not a reliable guide to quality in either direction. What matters more is what each quote includes: the assessment, the medication, the follow-up visits and what the clinic charges if a refinement is needed.
Two quotes are only comparable if they cover the same list, and the cheapest headline figure is often the one with the least included. Ask for the list in writing, and compare the lists rather than the numbers.
- Is the preoperative assessment included, and what does it cost on its own?
- Are post-operative drops and the follow-up visits included, and for how long?
- What is the clinic's enhancement policy, and what does a repeat treatment cost?

Questions about SMILE Pro vs LASIK
Each answer below is the short version; the question links to the page that carries it in full, with sources.
- Is SMILE Pro better than LASIK?
No single procedure is better for everyone. SMILE and LASIK both correct short-sightedness and astigmatism and both report high patient satisfaction. They differ in how the cornea is accessed, in the early recovery profile, and in how a re-treatment would be performed later.
- What is the main difference between SMILE and LASIK?
The difference is the access route. LASIK lifts a flap and reshapes beneath it; SMILE shapes a lenticule inside the cornea and removes it through a small incision. The rest of the treatment plan is built the same way, from your measurements.
- What is the difference between SMILE and SMILE Pro?
Both perform lenticule extraction. SMILE Pro is the same procedure performed on the newer ZEISS VISUMAX 800 platform instead of the earlier VISUMAX generation, which the manufacturer describes as faster and as including automated centration and rotation-compensation features.

Flap-based laser vision correction: a thin surface layer of the cornea is lifted, the tissue beneath it is reshaped, and the layer is replaced without stitches.
- LASIK vs SMILE
A flap procedure against a flapless one. The difference readers care about is what happens to the surface of the eye, not which laser is better.
- SMILE Pro vs Femto LASIK
Two current-generation laser platforms, one making a lenticule and one making a flap. Clinic branding is heavy on both, which is why the vocabulary matters as much as the technology.
- Myopia (short sightedness)
The eye focuses light in front of the retina, so near objects are clear and distant ones are blurred. It is the refractive error most commonly treated with laser vision correction.
- Dry eye
The tear film is unstable or insufficient, so the surface of the eye is uncomfortable and the vision can fluctuate. It matters before surgery because it is also one of the things refractive surgery can temporarily make worse.
- SMILE in Dubai
SMILE needs one specific laser platform rather than any excimer system, so fewer Dubai facilities offer it than offer laser eye surgery in general. Availability is worth asking about directly.
