Restrictions After Cataract Surgery: What Matters, How Long

Can you bend over, wash your hair or sit through a 13-hour flight in the week after a new lens goes in? Most restrictions after cataract surgery are shorter and looser than the printed sheets make them sound. Three carry real weight for the first one to two weeks: don't rub or press the eye, keep tap water, pools and saunas out of it, and skip heavy lifting and hard workouts. Reading, screens, walking and gentle bending are fine from the first days.

Hello, I'm Dr. Kim Sun-young, Medical Director at Healing Eye Clinic in Gangnam, Seoul. Cornea and cataract are my field; I was a clinical professor in cornea and cataract at Uijeongbu St. Mary's Hospital. With cataract surgery here, the same surgeon does your exam, your operation and your aftercare, and a medical interpreter for your language joins the consultation at no extra charge.

If you're still deciding when to travel, send the dates you could be in Seoul and a photo of your latest eye report or glasses prescription on WhatsApp, and ask which of these restrictions would fall on your flight home. The consultation is free, and that includes questions like this one before you book anything.

Which restrictions actually protect the eye?

Modern cataract surgery works through an opening of a few millimetres at the edge of the cornea. It's shaped like a short tunnel, and the American Academy of Ophthalmology describes these incisions as sealing on their own over time. In the first days, the pressure inside the eye holds that tunnel shut. Rub the eye hard and you can push it open for a moment.

Risks and side effects to know

So the rules that matter all aim at two things: keeping the wound closed and keeping germs out. An infection inside the eye after cataract surgery is rare, but it is one of the few complications that can cost real vision, and it usually starts with bacteria from the lids, fingers or water. For the first one to two weeks, these are the ones I'd hold you to:

• No rubbing or pressing. Itching is common while the eye heals; use your drops, dab the lid with a clean tissue, and wear the shield at night so you don't rub in your sleep.
• No tap water or soap in the eye. Shower with your eyes closed and your head tilted back, and wash around the eye with a damp cloth.
• No pools, hot tubs, sea swimming or sauna. That includes the jjimjilbang afternoon many visitors plan in Seoul; save it for another trip.
• No heavy lifting or hard workouts. Your suitcase counts. Have someone else lift it into the overhead bin.
• Drops on time. The antibiotic and anti-inflammatory drops are part of the treatment, not an optional extra.

The rules people over-follow

The other half of the sheet causes more worry than harm. Reading, TV and your phone don't strain a new lens. Vision may be blurry or oddly bright at first, but using the eye doesn't slow healing, and a slow walk around the neighbourhood the next day is fine.

Bending is where advice gets mixed. Tying your shoes or picking up a light bag is fine. What I'd avoid in the first days is a long head-down position with straining, like hauling something heavy off the floor or holding an inverted yoga pose.

You don't have to sleep flat on your back without moving. Sleep on your back or on the side of the eye that wasn't operated on, with the shield on, and the shield has done its job. Sunglasses aren't a medical rule either; they simply make glare and bright sun easier in the first weeks.

How long each restriction usually lasts

The timelines below are the usual ones in general practice, and your surgeon may shorten or extend them after seeing the eye. The American Academy of Ophthalmology notes that most people see better within a few days, while full healing takes about four to six weeks.

Driving depends on where you live. In the UK, for example, the GOV.UK rule is that you must be able to read a car number plate from 20 metres, with glasses if you need them. For how your vision itself changes over those weeks, my cataract surgery recovery timeline goes day by day.

What changes if you're very nearsighted?

Say you're 58, around -9.00 in both eyes, and a surgeon at home told you your eyes are long and need extra care. The restrictions above stay the same. Two other things change, and both matter on the way home.

First, a long, highly nearsighted eye generally carries a higher risk of retinal detachment after cataract surgery than an average eye, and that risk doesn't end when the first week does. The early signs are a sudden shower of new floaters, flashes of light, or a shadow moving in from one side like a curtain.

Second, once one eye is done, your two eyes can be far apart: the new one close to your distance target, the other still at -9.00. Glasses can't bridge a gap that large comfortably. If you wear contacts, pack one for the eye that hasn't been operated on; it lets the two eyes work together until the second surgery.

In your situation, I'd want the exam to settle whether both eyes can be done within one stay, or how long the gap between them would be. I don't pick a plan because it's convenient for the calendar. The measurements decide it, with you, and with your life at home in mind.

Can you fly home the week of surgery?

Standard cataract surgery doesn't leave a gas bubble in the eye, so cabin pressure isn't the worry it is after some retina operations. What matters is that the eye has been checked after surgery before you board, and most surgeons want to see it the next day.

Our hours shape that. We're open Monday to Thursday until 18:30, Friday until 21:00 and Saturday until 14:00, and closed on Sundays and public holidays, so a Saturday operation would put the next-day check on a closed day. The exact number of days for your plan is best settled at consultation; my guide to cataract surgery in Korea shows how the whole trip usually fits together. The clinic is a minute's walk from Sinnonhyeon Station, which keeps that morning-after visit short.

On the plane, keep the drops and the shield in your carry-on, not the checked bag. Cabin air is dry, so preservative-free artificial tears help. When you cross time zones, time the drops by hours since the last dose rather than by the clock; a long flight can quietly swallow two doses otherwise. Before leaving Seoul, take a photo of each bottle and of the dosing sheet so any doctor at home can see exactly what you're using.

If you're bringing a parent rather than going yourself, the companion's guide for parents covers the lifting and drop-giving you'll be doing for them.

Back home: which symptoms are normal, and which need a doctor today?

In the first weeks, a scratchy feeling, a mild ache, watering, light sensitivity and some glare or halos around lights are common, and they usually fade as the eye settles. Some people notice a thin shadow or crescent at the edge of their vision that fades over weeks. Healing speed differs from person to person, and that caveat applies to every timeline in this post.

Some eyes need closer watching. High myopia, as above. Diabetes, which can raise the chance of swelling at the centre of the retina. Glaucoma, where eye pressure after surgery needs checking. A past inflammation inside the eye (uveitis), which can flare after surgery.

See an eye doctor the same day if pain gets worse instead of better or doesn't ease with over-the-counter pain relief, if vision drops after it had improved, if redness spreads, or if you notice flashes, new floaters or a curtain. Bring your surgery summary from Seoul and those photos of your drops.

For anything that isn't urgent, such as when to taper the drops or when you can swim again, message us on WhatsApp with a photo of the eye taken in daylight. Before you leave Korea, book a visit with an ophthalmologist at home for the second to fourth week. The Healing Eye Clinic English site lists our address and phone number for their records. If your eye doctor at home wants to see the lens families we work with, our Korean head site has a page on premium intraocular lenses.

Your next step

If a surgeon at home has already measured your eyes, send those notes, especially the eye length if it's listed, on WhatsApp, and ask whether both eyes could be done in one stay or how long the gap would be. The consultation is free. When you come, the number that matters for a long, nearsighted eye is its length, because the lens power is calculated from it, and from there we choose your lens together.
