Booking a Cataract Consultation in Korea: Which Records to Send, Which Days to Avoid, and Why Old LASIK Matters

How does booking work when you live abroad?

You can book it on WhatsApp, but only ahead of time. There are no same-day appointments, an online request counts once the team has replied, and the clinic is closed on Thursdays, Sundays and public holidays. For you, the paperwork matters most: any record of your eyes from before the LASIK helps with choosing the power of the new lens.

Hello, I'm Dr. Kim Dong-Soo, Center Director for presbyopia and cataract at Sky Eye Clinic in Seoul. I'm a LENSAR Certified Laser Cataract Specialist (USA) and a J&J, Alcon Certified Cataract Specialist (USA).

Three things here matter for an eye that has already had laser surgery. Lens planning is measured on an IOLMaster 700. The clinic has both a LENSAR laser and a Signature Pro ultrasound system, so the surgical method can follow your eye. And a medical interpreter for your language is provided at no extra charge, while overseas patients pay the same fees as Korean patients.

A good first message is a photo of your latest eye exam, or the old LASIK paperwork if you still have it, plus the weeks you could travel. You can ask before booking anything: does my old surgery change which lens I should be thinking about?

Every exam, surgery and consultation at Sky Eye Clinic is by appointment, and same-day booking isn't available. Your Korea cataract consultation booking appointment is confirmed only once the team replies to your request. Hold off on non-refundable flights until that reply is sitting in your WhatsApp thread.

The week has two traps. Thursday is closed for equipment inspection, and Saturday (10:00 to 14:30) is for exams and surgeries only, with no follow-up consultations. Most cataract surgeons want to see the eye again within a day or two of the operation, so a Friday surgery pushes that check to Monday, and a Wednesday surgery pushes it to Friday. If you have a fixed number of days, start counting from a Monday or Tuesday.

The clinic is at 723-26 Banpo-dong, Seocho-gu, about a five-minute walk from Nonhyeon Station (Line 7 Exit 5 or Sinbundang Line Exit 4) or Sinnonhyeon Station (Line 9 Exit 2). Building A runs from B3 to the 10th floor and Building B is on the 1st floor, so note which building your appointment is in.

Can your old LASIK throw off the lens math?

Cataract surgery swaps your clouded natural lens for an artificial one. The power of that new lens is calculated before surgery from the length of your eye and the curve of your cornea, and standard formulas assume the cornea still has its original shape. LASIK and LASEK flatten the center of the cornea to correct myopia. That can make the formulas misread the cornea, and after earlier myopic correction the miss often leaves people more farsighted than planned.

That's why old surgery is the first thing I want to hear about. The numbers I'd like from you, if they exist: your glasses prescription before the laser, the corneal curvature (keratometry) readings from that time, the year, and whether it was LASIK or LASEK. If you're not sure which one you had, how LASIK and LASEK differ in what they leave of the cornea will help you read the old paperwork.

Having no records at all is common, and it doesn't rule you out. There are calculation methods built for eyes without a history, and your current measurements carry most of the weight. Old numbers give one more cross-check.

What gets measured at the consultation?

The clinic's first-visit exam sequence includes an auto-refraction reading for myopia, astigmatism and corneal curvature, and an eye pressure test, where 10 to 20 mmHg is normal and a higher reading leads to a detailed glaucoma exam. It also covers a corneal topography map and fundus photographs of the retina and optic nerve. The doctor then examines your eyes at the slit lamp.

For cataract planning, the IOLMaster 700 measures the eye without touching it, and the clinic also has an OQAS, which assesses the optical quality of the eye. That second reading is useful in your situation, because it helps separate blur caused by the cataract from blur caused by the old corneal surgery.

Retina checks usually mean dilating drops, and those blur close-up vision for a few hours. Don't plan to drive, and keep the rest of that day light. The clinic's guide to cataract tests and diagnosis lists each test in more detail.

Should you book now, or can the cataract wait?

The US National Eye Institute is plain about this: surgery is the only way to remove a cataract, but you may not need it right away. If you can still read, drive at night and work without trouble, waiting is a reasonable choice. A consultation still earns its place, because it gives you a baseline set of measurements and a clear view of your lens options before the cataract forces the decision.

Say you're 61, had LASIK for about minus 7 twenty years ago, and your optometrist has spotted an early cataract in the right eye only. You'd want to know whether the left eye will follow within a year or two, because when both eyes need surgery, the National Eye Institute notes that doctors usually operate on one eye at a time. In that case I'd look hard at how the two eyes will match, so the right eye's new lens doesn't leave you badly unbalanced against the left while you wait.

What moves the cost: lens type, one eye or two

Four things decide what cataract surgery costs in your case. First, the lens type: monofocal, multifocal or a specialty lens, as laid out on the clinic's page on IOL types. Second, whether one eye or both are treated. Third, whether the laser-assisted LENSAR method or the ultrasound method suits your eye. Fourth, how many follow-up visits you need in Seoul.

I confirm the procedure and the final fee after your exam, and the deposit and payment method are settled after the consultation as well. If you want a figure before you fly, ask on WhatsApp what it would cost for your case, and say which eye is affected and whether you're thinking of one lens type over another.

Who looks after your eye once you're home?

In Seoul, the same medical team stays with you from the first exam and consultation through surgery and the key checks after it. Once you fly, care moves to your own country, and it's worth setting that up before you leave. Book a visit with an ophthalmologist or optometrist at home for the weeks after your return, and carry a copy of your operation record: which eye, the date, and the model and power of the lens that was implanted.

Eye drops are a standard part of the first weeks after cataract surgery, so pack enough to cover the flight and your first days back. Keep a photo of the drop schedule on your phone in case the paper gets lost in transit.

Which problems can appear after surgery, and which need a doctor the same day?

In the first days, a gritty feeling, light sensitivity and some blur are common, and they usually fade over days to a couple of weeks. Rarer problems need a doctor the same day: pain that gets worse instead of better, vision that drops, a red eye with discharge, or new flashes, a shower of floaters or a shadow moving across your sight, which can signal retinal detachment. How quickly an eye settles differs between people, so judge by the trend over several days, not by one bad morning.

Months or years later, the capsule that holds the new lens can turn hazy, a change called secondary cataract. It's treated with a YAG laser, which the clinic has, and ophthalmologists at home use the same treatment. Uncontrolled diabetes, active inflammation inside the eye or a retinal problem usually need attention before cataract surgery is planned.

If you already know who will see you at home, put their name in your message along with the year of your old LASIK. Then ask which records from your surgery in Seoul you should carry back for them.

Risks to weigh before you pick flight dates

The consultation is free, and it can start on WhatsApp with a single photo: your pre-LASIK prescription if you can find it, or your most recent eye report if you can't, along with the weeks you could be in Seoul. The question to ask with it is how your old laser surgery affects the lens you should consider. At your exam, the first thing I'll compare is your cornea today against those old numbers, because that comparison shapes the lens I recommend.

Results vary by individual.
