LASIK / SMILE in Korea: timeline and follow-up you can't skip
Why eligibility testing takes a full day before surgery is even scheduled, how LASIK and SMILE differ in recovery, and the follow-up visits that make a same-week trip tight but workable.
Eligibility testing comes first, and it takes a day
Before any surgery is scheduled, Korean eye clinics run a full battery of tests — corneal thickness and topography, pupil size, dry eye assessment, prescription stability, and a general eye health check. This usually needs contact lenses to be out for a set number of days beforehand (commonly around 1–2 weeks for soft lenses, longer for hard lenses) so the cornea returns to its natural shape. Skipping that lens-free period and testing anyway can produce an inaccurate result.
Verify before you rely on this: Lens-free requirements before testing vary by lens type and by clinic protocol. Ask your specific clinic for their required number of days before you travel, so you don't arrive and fail eligibility on testing day.
LASIK vs. SMILE
| LASIK | SMILE | |
|---|---|---|
| Corneal flap | Creates a flap | Flapless — smaller incision |
| Typical recovery | Vision often sharp within a day | Slightly slower initial sharpness, often smoother after |
| Suited for | Wider range of prescriptions | Often preferred for higher myopia or thinner corneas |
Which one you're actually eligible for depends on the test results, not preference — a clinic recommending one over the other should explain which of your numbers (corneal thickness, prescription) drove that call.
A realistic same-week schedule
- Day 1: eligibility testing (a half day to full day)
- Day 2 (if eligible): surgery, usually done same day as or the day after testing
- Day 3: first follow-up, checking healing and vision
- Day 4–7: second follow-up before flying, especially important after long-haul flights with cabin pressure changes
Practical note: The follow-up visit before flying isn't a formality — clinics want to confirm the cornea is healing correctly before you're in a pressurised cabin and away from their care for the next weeks. If a clinic's schedule has you flying out the same day as surgery with no check the next day, ask why.
Dry eye symptoms and light sensitivity are common in the first weeks after either procedure and are not automatically a complication — but sudden vision loss, severe pain, or a sudden change in vision after you've returned home should be treated as urgent and reported to an eye doctor immediately, not waited out.
Work out the whole trip: open the total cost calculator with 6 nights filled in. That is a planning default, not a schedule — replace it with the dates your own clinic gives you.
