Vision correction in Korea: what international patients should know

What types of vision correction surgery are offered in Korea?

There are two groups: laser procedures that change the shape of the cornea, and lens procedures that add a lens inside the eye. Which type fits you depends on your cornea, your prescription and the health of your eyes, not on preference alone.

Laser procedures remove corneal tissue and cannot be reversed. Surgery does not stop the eyes from changing with age, so reading glasses may still be needed later in life.

Who is not suitable for vision correction surgery?

Not everyone is suitable, and the examination before surgery exists to find reasons not to operate. Be ready to hear that surgery is not advisable for you, or that a different type fits your eyes, and treat that as useful information.

Common reasons a doctor may advise against surgery, or postpone it, are listed below. The decision belongs to the ophthalmologist who examines you.

• A prescription that is still changing.
• A cornea that is too thin or too irregular in shape for the planned procedure.
• Eye conditions such as keratoconus, cataract, glaucoma or significant dry eye.
• Pregnancy or breastfeeding, when vision can fluctuate.
• General health conditions or medicines that affect healing. Tell the doctor your full history.
• Expectations that surgery cannot meet, for example never needing glasses again.

How long should you stay in Korea for vision correction?

Plan for the examination, the surgery and the follow-up checks, not for the surgery alone. The operation itself is short, but the clinic will want to see you afterward, and the number of checks depends on the procedure.

Ask the clinic in writing which checks must happen in person and how long after surgery each one takes place, then book your return flight after the last one.

• Contact lenses change the shape of the cornea, so you will be asked to stop wearing them before the examination. Ask for how long, because it differs for soft and hard lenses.
• The examination may include drops that widen the pupils and blur your vision for a while. Do not plan to drive or work straight after it.
• Ask whether the examination and the surgery take place on the same day or on separate days.
• Vision can be blurred or unstable at first. Keep your schedule light and do not drive until the doctor agrees.
• Ask how long to avoid swimming, saunas, eye makeup and dusty places, and plan sightseeing around that.

What should you ask a clinic before you book?

Ask who will examine and operate on you, why a particular procedure is suggested, what side effects are possible and what happens if you need more care after you return home. Get the answers in writing.

• Is the surgeon a board-certified ophthalmologist, and will the same doctor examine me and operate?
• Which procedure types does the clinic offer, and why is this one suggested for my eyes?
• What happens to my booking if the examination shows I am not suitable?
• What side effects are possible, such as dry eye, glare or halos at night, and how often do they occur?
• If my vision needs a further correction later, how is that handled for a patient living abroad?
• What is the total cost, including the examination, medicines and follow-up visits?
• Is the clinic registered to treat foreign patients?

What does a typical vision correction visit look like?

It moves from a detailed examination to a consultation, consent, the surgery and checks afterward. You should understand which procedure is planned and why before you sign anything.

1. Examination: your prescription, the thickness and shape of the cornea, pupil size, tear film and the health of the inside of the eye are checked.
2. Consultation: the doctor explains whether you are suitable, which options fit your eyes and what the alternatives are, including staying with glasses or contact lenses.
3. Plan and consent: you receive the plan, the cost and the possible side effects, and you sign a consent form.
4. Surgery: usually done with numbing eye drops while you are awake. Ask whether both eyes are treated on the same day.
5. Checks: the clinic examines your eyes after surgery, gives you eye drops and protective wear, and schedules the follow-up visits.

Doctors in Korea are required to explain surgery and obtain your consent. If you do not understand the explanation, ask for an interpreter before signing.

How do you look after your eyes once you are home?

Leave Korea with your eye drops, a schedule for using them, your records and a way to reach the clinic. Arrange a check with an eye doctor at home, because follow-up continues after the flight.

• Use the prescribed eye drops for as long as the clinic instructs, and ask what to do if you run out.
• Do not rub your eyes, and wear the protective shield or sunglasses as advised.
• Ask for a written record in English: the procedure, the date and your measurements before and after surgery.
• Keep the measurements taken before surgery. Eye doctors may need them later in life, for example when planning cataract surgery.
• Ask how the clinic handles questions from abroad, for example through a messaging app or email, and in which language.
• See an eye doctor promptly if you have increasing pain, a sudden drop in vision, or redness with discharge, and tell them what was done.
