Your Korea LASEK recovery timeline, day by day
Expect irritation, tearing and a gritty feeling for up to 3 to 4 days while the surface layer of the cornea regrows under a protective lens. Blurry vision follows for about 5 to 7 days, and sharpening carries on for several weeks after that. Past 40 there's one more fact to plan around: LASEK fixes distance vision, and close-up reading can still need glasses.
Hello, I'm Dr. Kim Sang-Myung, an ophthalmologist on Sky Eye Clinic's vision correction team in Seoul. I completed my ophthalmology training at Yonsei Severance Hospital and I'm a full member of the Korean Society of Cataract and Refractive Surgery.
Several doctors here have had LASIK or LASEK themselves, so the sore days described below are ones our team knows from the patient's chair. The clinic lists three versions of LASEK (standard, Amaris Red and 2Day LASEK), its laser for LASIK and LASEK is the SCHWIND Amaris Red SPT, and a medical interpreter for your language is provided at no extra charge.
| When | What it usually feels like | What it means for your trip |
|---|---|---|
| Surgery day | Numbing drops during surgery; stinging and watering start as they wear off | Go back to your hotel and rest with your eyes closed |
| Days 1 to 4 | Irritation, tearing, grittiness and light sensitivity, easing toward day 4 | Sunglasses, eye drops, audiobooks; very little screen time |
| Days 5 to 7 | Discomfort mostly gone; vision blurry and shifting through the day | Walking around is fine; small print is still hard |
| Weeks 2 to 4 | Clearer most of the day, some dryness, glare at night | Desk work is usually manageable; hold off on night driving |
| Months 1 to 3 | Vision settling toward its final level | Follow-up with an eye doctor at home |
The first four days are the hard part, and they're where LASEK parts ways with LASIK, whose discomfort lasts about half a day. The soreness comes from the exposed corneal surface, so it fades as the new epithelium covers it.
The blur in days 5 to 7 catches people off guard. A fresh surface is uneven at first, so vision can be crisp in the morning and soft by evening.
Days two and three are the ones to plan for. That's when the eyes ache, light feels harsh and a phone screen is the last thing you'll want to look at. I'd rather you book a quiet hotel room with blackout curtains for those nights than fit sightseeing in. By the end of the first week, most of that is behind you.
Why does LASEK heal more slowly than LASIK?
LASIK cuts a thin flap, about 160 micrometers thick, lasers the tissue underneath and lays the flap back down, so the surface is intact on day one. LASEK removes the surface epithelium instead, lasers the stroma directly, and lets the epithelium grow back under a protective lens. No flap means no flap-related complications and more of the cornea left untouched. The trade-off is the slower start.
That's why corneal thickness steers the choice. LASIK doesn't suit everyone, and when a cornea is thinner than a certain threshold, I recommend a LASEK-type procedure that keeps the most cornea in place. The number that decides it is the tissue expected to remain under the treatment, which comes from your thickness and how many diopters need removing. Many surgeons treat roughly 250 to 300 micrometers of untouched stromal bed as the floor for LASIK.
The clinic has a Pentacam and a Corvis ST: one maps corneal thickness and shape, the other measures how the cornea responds to a puff of air. An earlier post on how corneal thickness decides between LASIK and LASEK goes further into that comparison, and the clinic's LASEK page covers the three versions it offers.
What changes when you're over 40?
The American Academy of Ophthalmology describes presbyopia as the gradual loss of the eye's ability to focus up close, a normal part of aging that usually shows itself in the 40s. If you're nearsighted, you may have been hiding it: slide your glasses up onto your forehead and you can still read your phone. Correct your distance vision fully with LASEK and that trick disappears, so reading glasses often arrive sooner than people expect.
Say you're 47, about minus 6 in both eyes, with corneas a little thin for LASIK, and you read menus by taking your glasses off. Before planning LASEK, I'd want to know what fills your day: driving and screens at arm's length, or long stretches of reading. The clinic lists presbyopic LASIK and LASEK among its procedures, and at 47 that option belongs in the conversation alongside standard LASEK.
Some people would gladly keep sharp distance vision and buy a pair of readers. Others want to read a label unaided. Either can be right, and the time to choose is before surgery, not after it.
Risks and side effects to know
Dry eye also becomes more common after 40, and surface surgery can make it worse for a while. If your eyes already feel dry by mid-afternoon, mention it, because it affects how comfortable weeks two to four will be.
How many days should you plan in Seoul?
Work backward from the visit where the protective lens comes out. Every exam and surgery is by appointment, same-day booking isn't available, and an online request is confirmed only after the team replies. The clinic is closed on Thursdays for equipment inspection and on Sundays and holidays, and Saturday (10:00 to 14:30) is for exams and surgeries only, with no follow-up consultations.
That calendar matters for LASEK. A Wednesday surgery puts days 3 and 4 on a Saturday and a Sunday, so the lens check slips to Monday. If your leave is fixed, aim for surgery early in the week.
Contact lenses need to come out before the exam so the measurements are accurate: soft lenses for 5 days, hard and toric lenses for 10 days, and ortho-k lenses for at least 4 weeks. If you're pregnant or breastfeeding, hormone changes can throw off the readings, and the clinic suggests booking the exam after that period. Ask on WhatsApp how many days to plan for your own eyes once you have your dates.
For that message, the detail that changes the plan is what you wear now: soft, toric, hard or ortho-k lenses, and the date you could take them out. Add the date you land and the date you fly home.
Haze, dryness and slow healing: what can go wrong
The common reactions are temporary: soreness for the first 3 to 4 days, light sensitivity, vision that drifts through the day, and dryness that can linger for weeks or a few months. Less often, the surface heals slowly and the protective lens stays in longer. An infection under the protective lens is rare but needs same-day treatment. Corneal haze is more likely with larger corrections, which is one reason to wear sunglasses outdoors for the first months. Some eyes end up slightly under- or over-corrected and need glasses for certain tasks or a second treatment. Healing speed differs from one person to the next.
Some people should wait or choose something else: a prescription that changed within the past year, pregnancy or breastfeeding, a cornea with an irregular or cone-shaped map on topography, and active eye inflammation or a poorly controlled autoimmune condition. Serious visual side effects, though rare, have occurred when surgery went ahead despite an exam result advising against it. If your exam says no, I'll say no.
After you fly home, keep to the drop schedule, don't rub your eyes, and skip swimming pools and hot tubs for the first couple of weeks. Pain that grows after day 4, discharge, a white spot on the cornea or a sudden drop in vision means seeing an eye doctor that day. Carry a record of your surgery: which LASEK version you had, the date, and the prescription that was treated.
Your first message
The consultation is free, and it can begin on WhatsApp. Send a photo of your current prescription along with an older one from a year or two ago if you have it, since that shows whether your eyes have been stable. Ask one thing with it: at your age and with your numbers, should you plan around standard LASEK or the presbyopic version? At your exam, the first number I'll weigh is your corneal thickness against the correction you need, because that decides which of those two conversations we have.
Results vary by individual.
Questions answered
Can I fly home with the protective lens still in?
Flying doesn't damage a healing cornea, but cabin air is dry, and if the lens slips out or the eye flares up on the way, you're far from the team that placed it. Plan the flight after the lens has been removed and the surface has been checked.
How soon can I go back to screen work?
Screens are uncomfortable for the first 3 to 4 days. Many people manage short sessions by the end of the first week and full days during the second, with lubricating drops, larger text and regular breaks.
How long before the exam do I stop wearing contact lenses?
Soft lenses 5 days, hard and toric lenses 10 days, and ortho-k lenses at least 4 weeks. Lenses reshape the corneal surface slightly, and these breaks let it return to its own shape before it's measured.
Is it normal for vision to be worse on day 5 than on day 3?
It can be. The new surface smooths out unevenly, so vision often fluctuates for 5 to 7 days. A blur that comes with increasing pain or discharge is different and needs an eye doctor the same day.
Can I exercise during LASEK recovery?
Walking is fine from the first days. Most surgeons advise keeping sweat out of the eyes for about a week and avoiding contact sports, swimming and saunas for a couple of weeks while the surface firms up.
