Quick answer: Femto-LASIK, SMILE Pro (Femto-SMILE) and PRK all correct nearsightedness, astigmatism and farsightedness, and all give similar long-term vision in suitable eyes. Femto-LASIK gives the fastest recovery, SMILE Pro avoids a flap, and PRK treats the surface with no flap or incision, which can make it the safest choice for thinner corneas. I decide which one suits each eye after a full refractive screening.
Key Takeaways
- There is no single best laser. The best one is the one that suits your cornea, your prescription and your life.
- Femto-LASIK: fastest vision, back to desk work in 1–2 days.
- SMILE Pro: no flap, small incision, back to desk work in 2–3 days.
- PRK: no flap or incision, a longer recovery, often the safer option for thinner corneas.
- The refractive screening decides which option is safe for your eyes, or whether an ICL or no surgery is better.
How Do Femto-LASIK, SMILE Pro and PRK Differ?
All three change the shape of the cornea to correct your prescription. The difference is how the laser reaches the tissue:
- Femto-LASIK: the ZEISS VisuMax 800 creates a thin flap, the ZEISS MEL 90 reshapes the cornea underneath, and the flap is put back.
- SMILE Pro: the new generation of Femto-SMILE, performed on the ZEISS VisuMax 800. A thin lenticule is shaped inside the cornea and removed through a small incision, with no flap.
- PRK (surface laser): the thin surface layer of the cornea is removed, the MEL 90 reshapes the surface directly, and the surface grows back over a few days under a bandage contact lens.
Femto-LASIK vs SMILE Pro vs PRK: Comparison Table
| Femto-LASIK | SMILE Pro (Femto-SMILE) | PRK | |
|---|---|---|---|
| Flap or incision | Flap | Small incision, no flap | Neither |
| Lasers | VisuMax 800 + MEL 90 | VisuMax 800 | MEL 90 |
| Discomfort | Mild, for a few hours | Mild, for a few hours | Moderate, for 2–3 days |
| Functional vision | Usually the next day | Within a few days | Improves gradually over several weeks |
| Back to desk work | 1–2 days | 2–3 days | Longer; depends on how quickly vision clears |
| Bandage contact lens | No | No | Yes, for about 4–5 days |
| Dry eye early on | More common | Usually less | Usually less than LASIK |
| Contact sports | Flap can, rarely, move with a hard blow | Suitable | Suitable |
| Thinner corneas | Less suitable | Depends on the scan | Often the safer option |
| Book before an exam, wedding or trip | About 2 weeks | About 2 weeks | About 3–4 weeks |
| Long-term vision | Similar for all three in suitable eyes | ||
Which One Is Right for Me?
These are the situations I see most often, and the option I usually lean towards. The final decision always depends on your scans.
| Your situation | Option I usually consider first |
|---|---|
| You need to be back at work in a day or two | Femto-LASIK |
| You play contact sports or do martial arts | SMILE Pro or PRK |
| Mild dry eye, treated and controlled | SMILE Pro or PRK |
| Your cornea is on the thinner side but healthy (sometimes around 470–500 microns) | PRK |
| Applying to a military or police academy | Often PRK, after checking the academy’s current rules |
| Previous corneal surgery or a surface scar | PRK, in selected cases |
| Nearsightedness above about −10 D | Usually an ICL, not laser |
| Over 50 with early lens changes | Refractive lens exchange |
| Keratoconus or a weak cornea on the scan | No laser; keratoconus treatment |
| Over 40 and need reading glasses | Presbyond blended vision |
“Patients often ask me which laser is the newest. Newer does not always mean better for your eye. Some of my most satisfied patients had PRK, simply because it was the safest choice for their cornea.”
When Is PRK the Better Choice?
PRK is the oldest of the three, but it is still an excellent procedure. Because no flap or incision is made, it keeps more of the cornea’s strength. I often recommend PRK when the cornea is healthy but on the thinner side, sometimes in corneas around 470–500 microns thick, for people in contact sports or high-impact jobs, and for some eyes with surface irregularities or previous corneal surgery. The trade-off is recovery: the first two to three days are uncomfortable, and vision clears gradually over several weeks and can take 3–6 months to fully sharpen. Protecting the eyes from the sun is especially important after PRK: I ask patients to wear good sunglasses outdoors for about three months. Read the full comparison of LASIK and PRK.
Is PRK Better for Military and Police Academy Applicants?
Some patients applying to military or police academies prefer PRK, because there is no flap or incision. However, PRK does not make laser vision correction undetectable: corneal topography can sometimes show that the cornea has been treated. Admission rules differ and change over time, so please check the current rule directly with the academy before you decide.
Femto-LASIK or SMILE Pro?
If your eye suits both, the choice usually comes down to speed versus no flap. Femto-LASIK gives sharper vision the next day; SMILE Pro avoids a flap and may cause less dry eye early on. Read the head-to-head comparison of Femto-LASIK vs SMILE Pro and the full SMILE Pro guide.
How Do I Decide Which Procedure Is Safe for Your Eyes?
The decision is made during the refractive screening at your clinic visit. It includes corneal tomography to map corneal shape and thickness, a careful measurement of your prescription, a tear-film assessment, eye pressure and a retinal examination. If none of the three lasers is safe for your eyes, I will tell you, and we will discuss alternatives such as an ICL or lens exchange. Read the full requirements for laser vision correction.
What Are the Risks?
All three are safe, well-established procedures when the eye is properly screened. Dry eye and glare or halos at night can happen after any of them and usually improve over the first months. Femto-LASIK has flap-related risks; SMILE Pro has slower early vision and, rarely, difficulty removing the lenticule; PRK has more discomfort in the first days and, rarely, a faint corneal haze that usually fades. A small number of patients need a second treatment (enhancement). After any of the three, avoid rubbing your eyes, especially in the first week; after Femto-LASIK this matters most, because rubbing can move the flap. Read about laser vision correction risks.

What Patients Say (Google Reviews)
I had an excellent experience with Dr. Foaad El Sayyad! My LASIK PRK surgery was amazing, and the results have been incredible. During my first visit, Dr. Foad was extremely friendly, patient, and truly helped me overcome my fear and anxiety about the procedure.
Google review · Sayyad Eye Center, Mohandeseen · October 2026 · PRK
I had PRK at Sayyad Eye Center with Dr. Fouad El Sayyad. Having eye surgery was a hard step for me, but the center is beyond excellent and the doctor is excellent. Tonight is exactly one month, and my vision is back to 6/6.

Frequently Asked Questions
Which is better: Femto-LASIK, SMILE Pro or PRK?
None is better for everyone. All three give similar long-term vision in suitable eyes. Femto-LASIK recovers fastest, SMILE Pro avoids a flap, and PRK is often the safer option for thinner corneas. The refractive screening shows which one suits your eyes.
Is PRK weaker or less accurate than Femto-LASIK?
No. PRK uses the same excimer laser to reshape the cornea and gives similar vision once healed. It keeps more of the cornea’s strength because no flap is made. The difference is a slower, less comfortable first week.
Is SMILE Pro suitable for everyone?
No. SMILE Pro needs a healthy cornea and a prescription within its range. Some eyes are better suited to Femto-LASIK or PRK, and some are not suitable for laser at all.
Can all three treat astigmatism?
Yes. Femto-LASIK, SMILE Pro and PRK can all treat astigmatism together with nearsightedness or farsightedness. The suitable amount depends on your cornea.
Are these procedures painful?
Numbing drops are used, so none of them is painful during surgery. Femto-LASIK and SMILE Pro cause mild discomfort for a few hours. PRK is uncomfortable for two to three days while the surface heals.
Which one lets me return to work fastest?
Femto-LASIK: usually 1–2 days of desk work off. SMILE Pro: 2–3 days. PRK: longer, as vision clears gradually over the first weeks.
Can I use my phone after laser eye surgery?
Yes, as much as is comfortable. Take breaks and use your lubricating drops, because screens make the eyes drier. More important is protecting your eyes from the sun: wear good sunglasses outdoors, and after PRK keep wearing them for about three months, as sunlight can affect how the surface heals.
What if none of the three is safe for my eyes?
Then the answer may be an implantable contact lens (ICL), lens exchange after 50, or staying with glasses or contact lenses. I always discuss the safest option for your eyes, even if that means no surgery.

FAQS
-
Which is better: LASIK or Femto-LASIK?
Femto-LASIK is a newer development of traditional LASIK in the way the corneal flap is created, as it uses a femtosecond laser instead of a mechanical instrument. However, the final decision depends on the condition of the eye and the examination.
-
Which is better: Femto-LASIK or SMILE Pro?
There is no single answer for every patient. SMILE Pro may be suitable for selected cases of myopia and astigmatism, while Femto-LASIK may be more suitable for other patients. The decision depends on the eye examination and corneal measurements.
-
Is PRK weaker than Femto-LASIK?
No. PRK is not weaker. It is simply different. In some patients, PRK may be the safer or more appropriate procedure, especially when avoiding a corneal flap is important.
-
Is SMILE Pro suitable for everyone?
No. SMILE Pro is not suitable for every prescription or every corneal shape. A full refractive surgery evaluation is required.
-
Can these procedures treat astigmatism?
Yes, many degrees of astigmatism can be treated with Femto-LASIK, PRK, or SMILE Pro in suitable patients.
-
Are laser vision correction procedures painful?
The procedures are usually performed using numbing eye drops. Patients may feel pressure or mild awareness during surgery, but significant pain is not expected during the procedure. After surgery, discomfort varies by procedure and is usually more noticeable after PRK during the first few days.
-
Can I return to work quickly after surgery?
This depends on the procedure and your type of work. Many Femto-LASIK and SMILE Pro patients return to desk work within a short time, while PRK usually requires a longer recovery period.
-
Can I use my phone after surgery?
You may use your phone after surgery, but it is usually better to reduce screen time during the early recovery period because the eyes may feel dry or sensitive. Lubricating drops and rest can help.
-
Can laser vision correction fail?
No medical procedure can guarantee a perfect result in every case. However, careful patient selection, accurate measurements, appropriate technology, and following postoperative instructions all help improve safety and outcomes.
-
How do I know which procedure is right for me?
The only way to know is through a full refractive surgery consultation. This includes refraction, corneal mapping, corneal thickness measurement, dry eye assessment, and a complete eye examination.
