Patients researching this almost always find a wide range of numbers and no clear explanation for why. Here's the part that actually drives the price — and it's rarely the clinic, it's the lens.
I'm Dr. Baek Dong-won, Representative Director at EYEONCE Eye Clinic in Gangnam, Seoul. I understand the instinct to want a single number before you book a flight, but a flat quote for cataract surgery is almost always hiding a specific lens choice behind it — usually the cheapest one. The honest version is that the price depends on which lens fits your eyes and your goals, confirmed at a pre-operative exam, which is why we quote personally rather than publish one figure for every patient.
Cataract surgery itself — removing the eye's clouded natural lens — is a well-established procedure wherever it's performed. What changes the total cost is which artificial intraocular lens (IOL) replaces it. A basic single-distance lens costs less than a lens engineered to also correct astigmatism or reduce your dependence on reading glasses afterward. The surgery is largely the same; the lens inside your eye for the rest of your life is where the real decision — and the real cost difference — sits.
Beyond the lens, a complete quote should account for the pre-operative diagnostic work-up, the surgery for one or both eyes, and post-operative check-ups. If you're also dealing with presbyopia, it's worth reading about how that's assessed alongside cataracts on our presbyopia correction page — in some cases, the right premium lens addresses both at once rather than needing two separate treatments.
Most international patients plan for about 5-7 days: the diagnostic exam, surgery (sometimes staged a day or two apart for each eye), and a follow-up exam before flying home. More on what the procedure itself involves is on our cataract surgery page.
Our lifetime aftercare commitment applies to lens surgery the same way it applies to laser vision correction: if anything feels off after you're home, contact us at any time, and we'll guide you through a re-examination and next steps — including coordinating with a local ophthalmologist where that's more practical than flying back to Seoul.
Lens choice and cost can only be confirmed through a pre-operative diagnostic exam. Nothing here is a quote — message us with your eye reports for a personalized one.
