Is Eye Surgery in China Safe? An honest assessment

At China's top-tier eye hospitals, yes — for appropriately screened patients, eye surgery is as safe as at comparable Western centers. These institutions operate at some of the highest surgical volumes in the world, on the same laser platforms and lens brands used in the US and Europe, under national device regulation. But "China" is not one thing: the honest answer depends on which hospital, which surgeon, and how rigorously you're screened — so this guide covers what actually drives safety, the real risks no one should minimize, and the red flags that matter more than geography.

Volume: the quiet safety advantage

Surgical experience compounds. China performs millions of cataract operations every year and is one of the world's largest refractive-surgery markets — it was among the earliest and highest-volume adopters of SMILE, and Chinese centers have published some of the largest SMILE outcome series in the literature. What that means practically: a senior surgeon at a high-volume Chinese eye center routinely carries a personal procedure count that few Western practices can accumulate in a career. For standardized procedures — phacoemulsification, LASIK, SMILE — high surgeon volume is strongly associated with consistent outcomes and low complication rates. Volume isn't a guarantee of anything (nothing in surgery is), but it is the single most under-appreciated fact in the "is it safe abroad" conversation.

The counter-argument to the section you just read

A page selling the idea of surgery in China has an obvious incentive to stop at "volume." So here is the national picture, from the people best placed to publish it — and it does not flatter the country average.

The China National Eye Health Survey, led from Beijing Tongren Eye Center with co-authors at Zhongshan Ophthalmic Center and Shanghai General, examined 43,045 people aged 50 and over across 12 provinces in 2021–22. It reports China's effective cataract surgical coverage — the share of people who needed cataract surgery, got it, and ended up seeing 6/18 or better — at 38.7%, against a plain surgical-coverage figure of 57.2%. That is a relative quality gap of about a third, and it places China's national average below the South-East Asia regional median of 40.4%, though above the medians for Africa, the Americas, Europe and the wider Western Pacific.

The number that matters more for anyone choosing where to go is the spread. Effective coverage ranged from 16.7% in Heilongjiang to 71.0% in Beijing — a 4.3-fold difference inside one country, one health system, one set of national standards. Plain surgical coverage ranged from 41.2% in Henan to 87.3% in Hebei. The authors found this variation tracked the density of registered doctors and ophthalmologists per head, and not GDP per capita.

Two honest qualifications, because a number this blunt is easy to over-read. First, the survey was posted as a preprint in July 2024 and was not peer-reviewed at that posting. Second, and more important, the quality gap is not all surgical quality: the authors attribute about 40% of it to other eye disease present alongside the cataract and about 16% to posterior capsule opacification — the routine, easily-lasered clouding described in what happens after you are home. They argue the measure itself should be redefined to exclude the first of those. So read 38.7% as evidence of how much variation exists, not as a complication rate.

Equipment: same platforms, faster procurement

The femtosecond lasers, excimer platforms, phaco machines and premium IOLs at leading Chinese eye hospitals are the same Zeiss, Alcon and Johnson & Johnson systems installed in American and European operating rooms — and because Chinese hospital procurement cycles run fast, flagship centers are often on newer platform generations than a typical Western private clinic. Medical devices are regulated by the NMPA (China's national medical products regulator), and imported platforms carry the same manufacturer specifications worldwide. There is no "export-grade" laser; a VisuMax in Shanghai is a VisuMax.

Regulation and accreditation: how to read the tiers

Chinese public hospitals are graded under a national three-tier system; the top tier, grade-3A (三级甲等), indicates the highest classification for scale, specialist depth, teaching status and quality systems. Every public partner institution we work with is a grade-3A specialist center or a national-ranked ophthalmology department. On the private side, groups serving international patients (Aier, He Eye and comparable networks) add international patient departments, and some hold international accreditations such as JCI. What to check as a patient: the hospital's grade or accreditation, the named surgeon's credentials, and whether the center publishes or will discuss its complication-management pathway — a hospital that handles complications in-house, with a retina service on site, is materially safer than a standalone laser clinic anywhere in the world.

The risks — stated plainly

Flying somewhere does not change the underlying risk profile of eye surgery. It's the same procedure with the same documented risks:

• Refractive surgery (LASIK, SMILE, PRK): dry eye (usually temporary, occasionally persistent), glare and halos at night, under- or over-correction requiring enhancement, and rare flap or interface complications.
• Cataract surgery: posterior capsule opacification (common, treatable with a quick laser — see what happens after you are home), and rare but serious events — infection (endophthalmitis), retinal detachment, corneal swelling.
• All eye surgery: no honest surgeon guarantees an outcome, and some eyes are simply not good candidates — thin or irregular corneas, unstable prescriptions, uncontrolled dry eye, macular disease.

"Rare" is an adjective. Here is the number, and the question it gives you

Every clinic on earth calls endophthalmitis — infection inside the eye after surgery — "rare but serious," and then stops. Stopping there is what makes it useless to you, because "rare" is compatible with a twenty-fold range. Two published figures bracket it.

The ESCRS endophthalmitis study (J Cataract Refract Surg 2006;32:407–10) was a randomised, placebo-controlled trial across 24 European units. It was stopped early, in January 2006, because continuing was judged unethical once the effect was clear: 23 cases in 6,862 patients who did not receive an intracameral antibiotic at the close of surgery, against 5 cases in 6,836 who did — odds ratio 4.59 (95% CI 1.74–12.08). Round numbers: roughly 3 in 1,000 without, under 1 in 1,000 with.

For China, a 2023 survey of Asian eye institutions in International Ophthalmology (43:4151–62) records reported post-cataract endophthalmitis rates of 0.076–0.11% — about 0.8 to 1.1 per 1,000. That sits at or a little above the treated arm of the European trial and well below its untreated arm. It is not a head-to-head comparison: different decades, different denominators, different ways of counting a case. What it does is bound the order of magnitude, which is the thing a patient actually needs and almost never gets.

The two Chinese institutions in that survey were the Eye & ENT Hospital of Fudan University and the Eye Center of the Second Affiliated Hospital of Zhejiang University. Prophylaxis choice is a clinical decision for the operating surgeon and the centre's own protocol; the figures above are published research, not a recommendation, and nothing here predicts an individual outcome.

The centers we route to are academic hospitals with full subspecialty backup: if a rare complication occurs, the retina, cornea and glaucoma services that manage it are in the same building — not a referral flight away.

The related question — what actually happens if you need a second procedure, and what recourse you have as a foreign patient — is worth reading before you book rather than after. Most follow-on steps are routine ophthalmology any clinic at home can perform, provided it knows exactly what was done; and Chinese law gives patients a statutory right to their records, which is the provision that matters most in practice. We set out the revision categories, the five things to settle in writing before the operating day, and the dispute framework in revision, recourse and what to settle before surgery.

Screening: where safety is actually decided

Most poor outcomes in refractive surgery trace back to poor candidate selection, not surgical error. That's why the pre-operative day matters more than any other part of the trip: corneal topography, pachymetry, wavefront analysis, dry-eye assessment, dilated retinal exam — and for cataract patients, optical biometry and a macular check before any premium-lens conversation. Candidacy is always determined by the operating surgeon after these diagnostics, and at a reputable center the answer is sometimes no, or a different procedure than you came for. We tell every patient the same thing: a declined surgery is the system working — thin corneas that point to ICL rather than LASIK, or a prescription still shifting year to year that means waiting, are findings, not failures.

Communication and records: the practical safety layer

Safety doesn't end at the operating room door. At international patient departments, senior surgeons commonly speak English and coordinators translate everything else — consultation, consent forms, medication instructions. Your discharge package should include an English surgical report, the exact platform settings or implanted lens model and power, and an aftercare schedule your optometrist or ophthalmologist at home can follow. If a provider can't promise usable English records, that's a logistics failure that becomes a medical one the day your home doctor needs to know what was done. (Concierge-arranged cases include this handover as standard.)

How to actually check any of this — and the two things you cannot

Everything above tells you what to verify. Almost nothing published in English tells you how, so the advice usually dead-ends at "check the hospital's credentials" with no instrument attached. Three of these checks have one.

• Is the hospital, and the doctor, actually registered? China completed a national roll-out of electronic registration for medical institutions, physicians and nurses from April 2018. Basic practice-registration information for institutions and medical staff is published through National Health Commission channels — its website and the state Health China app and WeChat account — and a licensed institution's practice licence carries a QR code you can scan on the wall to confirm the licence is real. Beijing had activated accounts for over 100,000 physicians and 120,000 nurses by mid-2019, above 95% of its workforce.
• Is the laser or lens a registered device? The NMPA's Unique Device Identification database has been open to the public since 31 March 2020 and is searchable by product name, company or UDI code. If you have been given an exact platform and lens model — which you should insist on anyway — that is enough to look it up.
• Is the department nationally ranked in your subspecialty? Partly, and with real limits: see what Chinese hospital rankings do and do not measure before you lean on one.

The honest limits, stated plainly. These registers are Chinese-language, the interface and completeness vary by province, and every one of them verifies registration, not competence. A doctor can be perfectly registered and still be the wrong surgeon for your eye.

And two things you genuinely cannot verify from outside, which we would rather say than let our own checklist imply otherwise. No published Chinese ranking measures outcomes at the level of an individual surgeon — so when the checklist below says to ask about your surgeon's case volume, understand that you are asking them, and no public source will confirm the answer. And no centre anywhere publishes its own endophthalmitis rate as a matter of routine, which is exactly why the protocol question in the box above is worth more than a number you cannot audit. Treat a willingness to answer both questions specifically, in writing, as the signal — and a deflection on either as the red flag.
