Korea Smart Nova LASIK pain management: the first six hours
For most people the sore stretch is the first few hours after surgery: burning, tearing and a gritty feeling that sleep, an eye shield and your prescribed drops take the edge off.
Hello, I'm Dr. Kim Sang-Myung, an ophthalmologist in vision correction at Sky Eye Clinic in Seoul.
If your corneal scan says a flapless method doesn't suit your eye, I'll tell you, because switching methods turns a pain plan measured in hours into one measured in days. Smart Nova LASIK here runs on the SCHWIND ATOS laser through a 2mm opening with no flap, and several doctors on our team have had LASIK or LASEK themselves. A medical interpreter for your language is provided at no extra charge.
If your leave days are fixed, send a photo of your current glasses or contact lens prescription and your flight dates on WhatsApp, and ask which weekday your surgery and first check could land on. The consultation is free, and having your real dates in that first message keeps the conversation about your week rather than an average one.
Numbing drops go in before the laser starts, so what you notice in the room is pressure and a dimmed light. The eye is held steady for the short laser stage, and Smart Nova LASIK adds CenTrax, which corrects for small eye rotation and docking errors during that moment. Keep your gaze on the target light and it passes quickly.
Risks and side effects to know
The soreness arrives as the drops wear off. On the day, expect irritation, tearing and a grainy feeling. The U.S. Food and Drug Administration describes the same set, burning, itching or a sense of something in the eye, and notes that a doctor may suggest a mild pain reliever.
Why the flapless route tends to be gentler comes down to the surface. Smart Nova builds on New SMILE LASIK: the laser shapes a thin piece of tissue inside the cornea, which comes out through a 2mm opening, leaving the outer skin of the cornea largely untouched. A review of small-incision lenticule surgery in Eye and Vision describes less disruption to the corneal nerves than flap surgery, and those surface nerves are what make a surface procedure like LASEK sore for longer.
| When | What you'll likely feel | What helps |
|---|---|---|
| In the laser room | Pressure and dimmed light after numbing drops | Keep your gaze on the target light |
| Next morning | Mild scratchiness, vision that may still fluctuate | Lubricating drops, sunglasses, your first check |
| Days 2 to 7 | Dryness, worse on screens and planes | Frequent drops and screen breaks |
What helps in the hotel that night
Go straight back after surgery. We're about a 5-minute walk from Nonhyeon Station (Line 7 Exit 5, Sinbundang Exit 4) or Sinnonhyeon Station (Line 9 Exit 2), so a hotel on one of those lines keeps the ride short while your eyes are watering. Bring someone if you can; you shouldn't be reading street signs that afternoon.
Most of what makes the evening easier happens before surgery:
- Set phone alarms for every drop you're prescribed while your eyes are still comfortable. Reading a bright screen that night won't be pleasant.
- Bring the names of any medicines you take regularly, so the doctor can say which pain reliever, if any, fits you.
- Pack sunglasses and something to listen to. Podcasts beat scrolling.
- Eat before you go back to the room. Closed eyes and sleep do more for the first evening than anything else.
The shield goes on at night so you don't rub or press the eye while asleep. The urge to rub is strong when the eye feels gritty; the FDA's advice is simply not to, and it's the one rule I'd ask you to follow even half-asleep. Wash your hands before each drop and keep the bottle tip off your lashes.
Which weekday should your surgery fall on?
In short, this is the part of pain management people rarely plan for. The FDA advises seeing your doctor within 24 to 48 hours after surgery, and that first check is where any unusual discomfort gets looked at while you're still in Seoul. We're closed on Thursdays for equipment inspection and on Sundays and public holidays, and Saturday hours (10:00 to 14:30) are for exams and surgeries only.
So a Wednesday surgery pushes your first check to Friday, and a Saturday surgery pushes it to Monday. Neither is a problem medically; it only matters for flights. Look at the Korean holiday calendar too, because a holiday in the middle of your trip removes a clinic day.
Say you have a four-day break and land on a Thursday night. Friday is your exam. If the scan supports Smart Nova and surgery can be scheduled for Saturday morning, Sunday is closed, so your first check is Monday, and a Monday evening flight works only if you can spare that day. If you can't, I'd rather you add a day to the trip than board a plane before anyone has looked at your eyes after surgery.
Flying home with eyes a day or two old
Cabin air is dry, and a freshly treated cornea notices. Keep the lubricating drops you were given in your carry-on and use them often during the flight, keep the shield or sunglasses on if you sleep, and go easy on the seat-back screen. The pressure change in the cabin doesn't affect a laser-treated cornea; the flight restriction you may have heard about applies to gas bubbles used in some retina surgery.
For work, the FDA suggests planning a few days off until the early symptoms settle.
If the weekday puzzle is what's holding you back, send your landing and departure times on WhatsApp, along with any public holiday you're using, and ask which day your first check would land on. It also helps to mention when you last wore contact lenses, since lenses can change the corneal shape a scan reads, and to ask how long to leave them out before the exam.
When the scan points to LASEK instead
LASIK is not for everyone, and neither is every flapless method. Below a certain threshold, I recommend a LASEK-type surgery, which preserves the most residual cornea. A thin cornea doesn't automatically rule out the flapless route either, since New SMILE LASIK is also used for high myopia with thin corneas. The Pentacam and Corvis ST measure the thickness and stiffness that settle the question.
If you end up with LASEK, the pain plan changes. The surface layer is removed and regrows under a protective contact lens, discomfort can last up to 3 to 4 days, and blurring 5 to 7. LASIK, by comparison, usually means about half a day of discomfort. LASEK makes it a different trip: more days in Seoul, a quieter itinerary and a later flight. If you'd like to understand that trade-off before you arrive, how corneal thickness decides between LASIK and LASEK walks through it.
Several doctors here have had LASIK or LASEK themselves, so the recovery advice comes from people who have sat in that hotel room with gritty eyes. If your scan leaves very little margin, I'd rather move you to the method that keeps more cornea and give you a slower first week than a quicker one I'm uneasy about. Serious visual side effects, though rare, have happened when surgery went ahead against what an exam advised.
Pain that isn't normal, and what to do once you're home
Common and temporary: grit, tearing and light sensitivity in the first day or two, vision that drifts between clear and soft for some days, and dryness that can last weeks. How much discomfort you feel differs between people, and even between the two eyes of the same person.
Some people should wait or reconsider. Your prescription should have been stable for the past year, and you need to be 18 or older. Pregnancy or breastfeeding, and conditions that slow healing, such as poorly controlled diabetes or certain autoimmune diseases, are among the reasons the FDA lists for LASIK not being right for someone. A cornea that is thin or irregular for its shape, which can be an early sign of keratoconus, is a reason to slow down and look further.
What's not normal: severe or increasing pain, vision getting worse instead of better, or a red eye with discharge. The FDA's advice is to contact your doctor immediately instead of waiting for a scheduled visit. In Seoul, the same medical team supports you from examination through surgery and the key post-operative checks, and our complication prevention program includes a daily equipment check. You can see who operates on the named-surgeon page before you book.
Your first message can be short: a photo of your latest prescription and the dates you could be in Seoul, sent on WhatsApp, with the question of which weekday surgery should fall on so your first check doesn't land on a Thursday or Sunday. The consultation is free. On exam day, the measurement I'll read first for your pain plan is the corneal thickness map, because it tells us whether you're planning for an evening of grit or several days of healing.
Results vary by individual.

Questions answered
Can I visit a jjimjilbang or go swimming during the trip?
Not this time. The FDA advises avoiding swimming, hot tubs and whirlpools for one to two months after surgery, and the hot pools and steam rooms of a Korean bathhouse belong in the same group. Save it for a later visit.
Can I wear eye makeup on the flight home?
Leave it off. FDA guidance is to avoid makeup, creams and lotions around the eye for up to two weeks after surgery, or until your doctor says otherwise.
What if I blink or sneeze during the laser?
You're awake throughout with numbing drops in, and the laser stage itself is short.
When can I get back to the gym?
The FDA says strenuous contact sports such as boxing or football should wait at least four weeks. For lighter exercise, keep sweat out of your eyes and ask at your first check when to restart.
Do I need someone with me on surgery day?
It helps. Your eyes will water and vision will be soft for the walk or taxi back, so a companion makes the first evening easier. Inside the clinic, a medical interpreter for your language is provided at no extra charge.
