SMILE LASIK

What is SMILE LASIK?

SMILE LASIK is a laser vision correction procedure performed at Smile Eye Clinic Korea in Gangnam, Seoul, using the ATOS femtosecond laser. In short, it reshapes the front surface of your cornea so that light focuses correctly on the retina, reducing or removing your dependence on glasses and contact lenses. A thin protective layer (a flap) is created in the cornea with the femtosecond laser, the cornea is gently reshaped to correct your prescription, and the flap is repositioned to heal naturally. The whole laser treatment usually takes only a few minutes per eye, though you should plan to spend one to two hours at the clinic on the day.

SMILE LASIK is often chosen for its quick visual recovery and its ability to correct nearsightedness, farsightedness, and astigmatism. Whether it is the right method for you is confirmed by an ophthalmic surgeon during an in-person examination in Seoul.

Who is SMILE LASIK for?

Good candidates are generally adults whose eyeglass prescription has been stable for at least a year and who have healthy eyes and a cornea thick enough to allow flap creation. It is frequently suitable for people with low to moderate nearsightedness, some degrees of farsightedness, and astigmatism. It may not be suitable if you have very thin corneas, severe dry eye, certain corneal conditions, or are pregnant or breastfeeding.

Because candidacy depends on precise measurements of your individual eyes, eligibility cannot be decided online or before you travel. A surgeon confirms whether SMILE LASIK suits you only after a full in-person examination at the clinic in Gangnam, Seoul.

How SMILE LASIK works, step by step

• In-person examination: Detailed scans of your cornea, prescription, eye pressure, and tear film are taken on site in Seoul.
• Numbing drops: Anesthetic eye drops are applied so the surface of the eye is numb before treatment begins.
• Flap creation: The ATOS femtosecond laser forms a thin corneal flap with sub-micrometer precision.
• Corneal reshaping: An excimer laser removes a microscopic amount of tissue to correct your prescription.
• Flap repositioning: The flap is laid back into place, where it begins to adhere on its own.
• Same-day check: Your eyes are reviewed before you leave, and a follow-up is scheduled for the next day.

Does laser eye surgery hurt during the procedure?

No, the procedure itself is generally not painful. Before treatment begins, numbing eye drops are placed in your eyes, so most people feel pressure or a sense of touch rather than sharp pain while the laser works. The laser stage lasts only a short time per eye. After the numbing drops wear off, it is common to feel mild irritation, watering, or a gritty, foreign-body sensation for several hours. These feelings usually ease within the first day and are managed with the eye drops your surgeon prescribes.

The technology behind it

SMILE LASIK at the clinic is performed with the ATOS femtosecond laser, paired with the CenTrax predictive centration system, which helps align treatment precisely on the visual axis. Diagnostic measurements are taken with ZEISS systems so that your corneal map and prescription are captured in detail before any treatment is planned. This combination of accurate diagnostics and precise laser delivery supports careful, individualized treatment for each eye.

SMILE LASIK vs flapless SMILE PRO

SMILE LASIK creates a thin corneal flap and uses an excimer laser to reshape the surface, which makes it versatile for a range of prescriptions including farsightedness. SMILE PRO is a flapless method: instead of a flap, the surgeon removes a small lenticule of tissue through a tiny incision, which preserves more of the cornea’s surface structure and can mean a lower tendency toward dry eye for some patients. Neither method is universally better; the right choice depends on your cornea, prescription, and lifestyle, and your surgeon will explain the neutral pros and cons of each at your exam.

Recovery timeline

• Day 1: Vision is often clearer quickly, though it may fluctuate; rest your eyes and use prescribed drops.
• Days 2 to 7: Most everyday activities resume; screens and light exercise are usually possible as advised.
• Weeks 2 to 4: Vision continues to settle; avoid swimming, eye rubbing, and dusty environments per guidance.
• Months 1 to 3: Vision stabilizes further, with follow-up checks confirming healing.

Risks and considerations

As with any surgery, SMILE LASIK carries risks. Temporary dry eye, glare, halos around lights at night, and fluctuating vision are the most common short-term effects, and most improve over time. Less commonly, healing can vary between individuals, and an enhancement procedure may occasionally be discussed. Results vary by person, and no honest clinic can promise a specific outcome. Your surgeon will review your personal risk profile during the in-person exam.

Frequently asked questions

How long does SMILE LASIK take?

The laser treatment itself usually takes only a few minutes per eye. However, you should plan to be at the clinic in Gangnam, Seoul for roughly one to two hours, which includes preparation, the procedure, and a brief post-operative check before you leave.

When can I see clearly after surgery?

Many people notice clearer vision within the first day, though it can fluctuate at first. Vision typically continues to settle over the following days and weeks, with full stabilization over the first one to three months. Your follow-up visits track this healing.

Can my eligibility be checked before I travel to Korea?

No. Remote or online diagnosis is not permitted in Korea, so candidacy cannot be confirmed before arrival. A surgeon decides whether SMILE LASIK is suitable only after a full in-person examination in Seoul, where your cornea and prescription are measured directly.

Is SMILE LASIK or SMILE PRO better for me?

It depends on your individual eyes. SMILE LASIK uses a thin flap and suits a wide prescription range, while flapless SMILE PRO preserves more corneal surface. Your surgeon compares both options at your in-person exam and recommends the one best matched to your cornea and lifestyle.

How should I prepare for the day of surgery?

Stop wearing contact lenses for the period your clinic advises before your exam, since lenses can affect corneal measurements. Avoid eye makeup on the day, arrange someone to help you travel home, and bring sunglasses, as your eyes may be light-sensitive for a short time afterward.
