How Old Do You Need to Be for SMILE Eye Surgery? The Right Time

Hello, this is Gangnam Smile Eye Clinic 😊💙

The 2026 College Scholastic Ability Test (Suneung) is just around the corner.

There are many things students want to do after the Suneung,

but for most students who have experienced discomfort with glasses or contact lenses during their long study hours,

vision correction surgery is often the first thing that comes to mind.

Especially these days, with the growing popularity of SMILE eye surgery for its fast recovery and safety,

many people are probably wondering, ‘How old do you need to be for SMILE eye surgery?’

Today, for students preparing for the Suneung and those considering vision correction surgery after the exam,

we will delve into the age requirements for SMILE eye surgery and the eligibility criteria for other vision correction procedures.

How old do you need to be for SMILE eye surgery?

SMILE eye surgery is generally available for individuals aged 18 and older.

However, for high school seniors who have just finished the Suneung, it’s important to first confirm vision stability rather than undergoing surgery immediately.

In other words, it’s not just about age;

• Has your vision remained largely unchanged for the past six months?
• Are your corneal thickness and shape suitable for surgery?
• Do you have dry eyes or any other eye conditions?

The eligibility for SMILE eye surgery depends on these individual eye conditions.

What are the age requirements for vision correction surgeries other than SMILE?

In addition to SMILE eye surgery, other vision correction procedures include

LASIK, LASEK, and ICL (Implantable Collamer Lens).

Each surgical method may have slightly different applicable ages and conditions.

• LASIK, LASEK: Usually available for individuals aged 18 and older after vision stabilization.
• SMILE eye surgery: Safer with faster recovery due to no corneal flap.
• ICL (Implantable Collamer Lens): Recommended for individuals with thin corneas or severe myopia, generally aged 19 and older.

Therefore, even for students who have completed the Suneung, the most suitable vision correction surgery may vary depending on the examination results.

It is safest to visit a clinic and determine a customized surgery through a precise eye examination.

‘Precise Examination’ is a must before checking SMILE eye surgery age eligibility.

Once the Suneung is over, I recommend taking some time to get a precise examination at an ophthalmology clinic.

SMILE eye surgery eligibility is not solely determined by age; it must be assessed after a comprehensive evaluation of recent vision changes and overall eye health.

If your vision has remained stable for at least six months through a precise examination,

then you can discuss surgical suitability with the medical team.

If you are still in your growth period or your vision is fluctuating,

it is advisable to postpone the surgery because vision stability has not yet been secured.

This is much more important than the simple criterion of ‘being 18 years or older’.

During the examination process, corneal thickness, retinal diseases, intraocular pressure,

the dryness of the eyes, and overall eye health are thoroughly checked.

Only after this process can you expect safe and satisfactory results, even if you meet the SMILE eye surgery age requirement.

If you decide to proceed with surgery, timing is also important.

We recommend scheduling the surgery considering the recovery period so that it does not interfere with academic or admission schedules.

Utilizing the winter break after the Suneung, in particular,

allows for sufficient recovery time,

making adaptation after surgery much smoother.

If the vacation period is short or time is tight,

you might consider New SMILE eye surgery.

New SMILE eye surgery does not create a corneal flap

and is a minimally invasive correction procedure performed with only a micro-incision of about 2mm,

using a femtosecond laser to precisely remove the necessary amount of corneal stroma.

Unlike traditional LASIK and LASEK, this method reduces the risk of corneal nerve damage and opacity,

and is characterized by minimizing side effects such as dry eyes and glare.

Furthermore, the recovery speed is fast enough to allow face washing, showering, light outings, and

makeup from the day after surgery.

At Gangnam Smile Eye Clinic, we see your eyes differently.

One thing I definitely want to emphasize is that

vision correction surgery should not be decided solely by price.

No matter how advanced the surgical equipment is,

ultimately, the results depend on the medical team's experience and precise diagnostic system.

Based on extensive surgical experience, our Gangnam Smile Eye Clinic

meticulously analyzes each patient's eye structure and vision change patterns

and operates a 1:1 customized examination system.

Especially for students who meet the SMILE eye surgery age requirement or

patients in their early 20s,

we prioritize evaluating vision stability after the growth period

and do not recommend unnecessary surgeries.

Furthermore, all surgeries are personally conducted by a specialist, from examination to

consultation, surgery, and post-operative care, taking full responsibility for the entire process.

During the pre-surgical precise examination phase, about 50 items are meticulously checked, including corneal thickness, intraocular pressure, tear film stability, and corneal shape analysis.

Thanks to this systematic approach,

we maintain stable vision retention rates and high patient satisfaction after surgery.

If you have any further questions regarding vision correction surgery,

please feel free to contact Gangnam Smile Eye Clinic at any time.

We will support your new beginning with clear vision.

Frequently Asked Questions

What is the minimum age for SMILE eye surgery?

SMILE eye surgery is generally available for individuals aged 18 and above. However, there should be no change in vision for 6 months prior to surgery, and the eligibility for surgery is determined after a comprehensive evaluation of the individual's eye condition, including corneal thickness, shape, and dry eye syndrome.

Can I get SMILE eye surgery immediately after the Suneung (Korean SAT)?

No, it is important to first confirm vision stability rather than undergoing surgery immediately after the Suneung. It is recommended to discuss the suitability for surgery with medical staff after your vision has remained stable for at least 6 months.

What other vision correction surgeries are available besides SMILE?

In addition to SMILE, other vision correction surgeries include LASIK, LASEK, and ICL (Implantable Collamer Lens). LASIK and LASEK are possible for individuals aged 18 and above after vision stabilization, while ICL is recommended for those aged 19 and above with thin corneas or severe myopia.

What tests should I undergo before SMILE eye surgery?

Before SMILE eye surgery, a precise examination is necessary to thoroughly check about 50 items, including vision stability, corneal thickness, retinal diseases, intraocular pressure, tear film stability, and corneal shape. This is essential for safe and satisfactory results.

How long is the recovery period after SMILE eye surgery?

For New SMILE eye surgery, the recovery speed is fast enough that washing your face, showering, light outings, or makeup are possible from the day after surgery. It is advisable to schedule the surgery considering academic or admission schedules to ensure sufficient recovery time.

What is the most important factor when choosing a vision correction surgery clinic?

Vision correction surgery should not be decided based solely on price. The experience of the medical staff and the precision diagnostic system determine the outcome more than the surgical equipment, so it is crucial to confirm personalized examinations tailored to the patient's eye condition and the responsible conduct of the specialist.
