Contact Lens Before Eye Surgery in Korea: Stop Wearing Days

The number of days you must stop wearing contact lenses before vision correction surgery in Korea depends on your lens type (soft, hard or astigmatism lenses) and the clinic's instructions, so ask before you book flights. If you don't stop long enough, corneal thickness and prescription readings will be inaccurate, and your surgeon would be deciding on unreliable data.

The Most Overlooked Step Happens Before You Fly

Most people focus on which procedure to choose and how much it costs, but forget something you must do at home first: stop wearing your contact lenses.

Skipping this has real consequences. Contact lenses change the shape of the cornea and affect the condition of the eye surface. If you haven't stopped long enough, your corneal thickness and prescription readings will be inaccurate at the pre-op exam.

Those two numbers are what the surgeon uses to decide whether SMILE Pro, SMILE LASIK or Evo ICL suits you. Inaccurate data means an inaccurate decision. Flying all the way to Korea only to get unreliable test results is the worst outcome.

How Many Days Should You Stop Wearing Contact Lenses?

You may be hoping for a simple answer like "7 days", but the clinic's position is that the number of days depends on the lens type and the clinic's instructions.

Lenses differ a lot. Soft lenses, hard lenses and astigmatism lenses affect the cornea differently, and how long you've worn them and how many hours a day also matter. Two people who both wear contacts may need different stop periods.

So there is only one correct approach: before you book your flight, use the live chat on this website to tell us which type you wear, how long you've worn it and how many hours a day. We'll reply with the clinic's instructions, and then you can book your dates.

Order matters. If you book flights first and ask afterwards, you often find there isn't enough time left to stop wearing lenses.

What to Do While You've Stopped Wearing Contacts

During the stop period you'll wear glasses. Many people only wear contacts and have no idea where their old glasses are, so find them before you leave and bring them to Korea.

If your old glasses no longer match your current prescription, they may feel uncomfortable, but not wearing contact lenses still takes priority. If you're unsure, ask during your consultation.

Also, don't sneak in contacts "just for a little while". Even a few hours the day before the exam can still affect the results. After stopping for several days, don't undo it on the last day.

How to Prepare for the Day of Surgery

The clinic's instructions for the day are simple, and each has a reason:

The last item is the one most often underestimated. The detailed pre-op exams at Gangnam Good Eye Clinic take about 2–3 hours, plus the surgeon consultation and the surgery itself, so don't schedule other important plans that day.

What Else Should You Bring?

Not required, but it makes things smoother:

• Eye exam reports from home: if you've had refraction or corneal tests done, they can serve as a reference
• Your current glasses prescription: a photo of the prescription slip or the markings on your glasses works too
• Eye drops you currently use: if you have dry eyes or use artificial tears, bring a photo of the bottle
• Your return flight time: tell the surgeon during the consultation, and the surgeon will confirm based on the procedure and your recovery

The last point deserves emphasis. Your return time isn't just a side detail; it's a condition the surgeon considers when planning your procedure and post-op instructions. Bring it up yourself instead of waiting to be asked.

Check Clinic Closed Days Before Booking Flights

Gangnam Good Eye Clinic is closed on Thursdays, Sundays and public holidays. A typical Thursday-to-Sunday trip would run into the closed days.

The clinic is about a 2-minute walk from Gangnam Station, at 107 Teheran-ro, Gangnam-gu, Seoul (7th and 9th floors). It's in the city center, so it's easy to fit your appointment around the rest of your itinerary.

Common Questions About Contact Lens Prep

Q. I wear daily disposables. Do I still need to stop for that long?
Different lens types have different requirements. Tell us which type you wear and the clinic will give you instructions.

Q. What happens if I don't stop long enough?
Your exam data will be inaccurate. The surgeon may be unable to make a decision that day, making the trip a wasted one.

Q. Can I stop wearing them after I arrive in Korea?
Not recommended. The stop period should begin before you leave, and starting after arrival is usually too late.

Q. Does the exam day really take 2–3 hours?
Yes. This is the time the clinic gives, so leave room for it when planning your schedule.

Q. Can I do this if I don't speak Korean?
Yes. You can consult and book through the "Request booking" button or the live chat on this website.

Just Ask These Few Things First

Use the live chat to tell us: your contact lens type, how long you've worn them, your current prescription and roughly when you'd like to visit Korea. We'll reply with the stop period and the dates we can arrange.

Book your flights after confirming, and the whole trip will go much more smoothly.
