The first six weeks: who does cataract surgery, and who checks the eye after you fly home

An ophthalmologist performs the operation itself. Around that surgeon, a diagnostic team takes the measurements, coordinators handle scheduling, and in some health systems the later checks are shared with an optometrist. Knowing who does which part tells you whose name belongs on each line of your plan.

That arrangement is useful to remember, because a trip to Seoul works in a similar way: the operation and the first days are in Korea, and most of the healing is somewhere else.

At EYEONCE, the roles look like this. Diagnostic technicians run the pre-op measurements on Topcon diagnostics. English-speaking coordinators handle WhatsApp messages, scheduling and travel questions. The surgery itself uses the Centurion phacoemulsification system: a circular opening is made in the lens capsule, the clouded lens is broken up with ultrasound and removed, and an intraocular lens (IOL) is placed where it was.

The surgeon's main judgment call happens before surgery day, in choosing that lens. Four things get mapped at the consultation: which distance matters most for daily life, whether astigmatism needs correcting, how much night glare the person will tolerate, and how much they want to be free of glasses. A retired parent who drives at night and dislikes halos around headlights is a different conversation from one who reads all day and hates reading glasses. When the corneal measurements show meaningful astigmatism, a toric version of the lens comes into the discussion, because otherwise that blur stays after surgery.

Most people see better within a few days, according to the American Academy of Ophthalmology, though full healing takes about 4 to 6 weeks. The first week is about protecting the eye while that starts.

On surgery day, expect the eye to feel scratchy or watery and to look blurry for the first hours; many people describe light as too bright that evening. A companion or arranged transport for surgery day is part of the plan, so this is the night for the hotel room, not the city.

For the rest of the week, three habits do most of the work. An eye shield goes on during sleep for a week. Eye drops go in exactly on the schedule the surgeon gives, which is easier when a family member owns the timetable rather than the patient. And nobody rubs the eye, even when it itches. EYEONCE also gives a clear timeline for washing the face and bathing safely, which matters more than people expect in a hotel shower.

Gentle walking is usually fine. Strenuous exercise waits for a month, so a long hiking day or a heavy suitcase lift at the airport is a question to put to the surgeon at the last check.

Serious problems are uncommon, and the National Eye Institute notes that 9 out of 10 people who have the surgery see better afterwards. Complications still exist, and some show up after the flight, so everyone in the family should know what they look like.

The American Academy of Ophthalmology lists these risks:

• Eye infection.
• Ongoing swelling of the front of the eye or inside the eye, or swelling of the retina.
• A detached retina, where the retina lifts away from the back of the eye.
• Vision turning cloudy or blurry weeks, months or years later, called posterior capsule opacification. It's treated with a short laser procedure, a YAG capsulotomy.

What to do depends on timing and severity. Pain, a sudden drop in vision, a shower of new floaters, flashes of light, or a shadow moving across the vision are reasons to see an ophthalmologist the same day, wherever you are. EYEONCE's guidance is the same: if you feel a foreign-body sensation or pain, visit us immediately, or see a local ophthalmologist first and then contact us. Slow clouding months later is less urgent but still worth an exam, because it's usually the capsule rather than the cataract coming back.

The lifetime aftercare policy covers what happens after that contact: a detailed re-examination and, where appropriate, help with re-treatment, with the specific conditions confirmed at the consultation.

When a family books cataract surgery from abroad, the flight home is the part of the plan I most want to get right. The check the day after surgery tells me whether the pressure and the new lens look the way they should, and a fixed flight shouldn't be what decides whether that check happens. A few spare days in Seoul cost less worry than a rushed departure.

If one worry is stopping your family from booking, send that question with a photo of the latest eye report.

Before the last check in Seoul, ask for copies of everything your eye doctor at home will need to pick up the care. A useful folder holds:

1. The operative summary, including which eye, the date, and the lens type and power that was implanted.
2. The pre-op measurements used to choose that lens.
3. The written drop schedule, with the names of each drop and when it tapers.
4. The findings from each post-op check in Seoul, especially eye pressure.
5. Any instructions about the second eye, if only one eye was done on this trip.

This is the paperwork a local ophthalmologist or optometrist needs to continue the checks without starting from zero. For a broader overview of planning eye surgery in Korea, the South Korea eye surgery starting guide covers the general steps, and the EYEONCE home page lists every procedure.

When you're ready to test the plan against real dates, send two things on WhatsApp: your parent's most recent eye exam report as a photo, and the window you can travel. The team plans the schedule around those dates, and you'll see how the 5 to 7 days fall around the clinic's closed Wednesdays and Sundays before anyone books a flight.
