They turned you down at the workup — what actually happens next
Screening evidence researched September 2026 · Prices researched July 2026
This is the question the whole industry is quietest about, and the silence is not accidental — it is commercially uncomfortable to answer. Here is the answer anyway. Most refusals are not a no; they are a redirection to a different operation. The two findings that stop a laser procedure more than any others are a cornea that is too thin and a topography map the surgeon will not cut into, and neither of those closes off surface ablation or an implanted lens. And the headline statistics are worse than reality: in the largest screening series with a published breakdown, 38.4% of people who were screened did not go on to have surgery — but only 12.6% were judged to have a contraindication. Most of the gap is people who decided not to, not people who were refused.
Start with the number that is doing the frightening, because it is the wrong number
If you search for how many people are turned down for laser eye surgery you will meet, sooner or later, a figure around seventy per cent. It is real, it is recent, and it is almost entirely irrelevant to a thirty-year-old myope booking a flight.
It comes from a retrospective review of 648 consecutive patients presenting for LASIK evaluation at a refractive centre between November 2022 and April 2023, published in Cureus in June 2025. The overall non-candidacy rate was 69.4%. But the three largest reasons were emmetropic presbyopia (36.9%), abnormal topography (31.3%) and hyperopic presbyopia (25.6%) — and two of those three are presbyopia, the age-related loss of near focus that arrives in the mid-forties. A presbyopic patient with no short-sightedness left to correct is not a person who was refused. They are a person for whom LASIK was never the operation in the first place, counted in a denominator built from everyone who walked through the door.
The same paper does the useful thing and splits by age. Among patients under 45 the reasons rearrange completely: abnormal topography 43.5%, corneal thinning 24.5%, severe myopia 20.7%. That is a different problem with a different shape, and it is the one a fly-in reader is actually facing.
The second series, and why the agreement between them matters more than either one
The better guide to the question "will I be sent home" is older and larger: 1,067 consecutive candidates screened for refractive surgery by a single surgeon at one centre between 2007 and 2012, mean age 39, published in Cornea in October 2014.
| Outcome of screening | Number | Share |
|---|---|---|
| Went on to have refractive surgery | 657 | 61.6% |
| Did not have surgery, for any reason | 410 | 38.4% |
| Judged to have a contraindication | 134 | 12.6% |
| Surface ablation judged the better option than LASIK | 106 | 9.9% |
Torricelli AAM, Bechara SJ, Wilson SE. Screening of refractive surgery candidates for LASIK and PRK. Cornea 2014;33(10). Single surgeon, Cole Eye Institute, 2007–2012; 1,067 candidates, 519 male / 548 female, mean age 39 ± 12 (range 17–78).
Two thirds of the people who did not have surgery were not refused it. 38.4% did not proceed; 12.6% had a contraindication. The remainder is the ordinary attrition of anyone making an elective decision — cost, timing, second thoughts, a plan to come back later. If you have been reading drop-out rates as rejection rates, you have been reading a number roughly three times too large.
And notice the fourth row. In nearly one in ten cases the finding did not stop surgery at all; it changed which surgery. That row is the whole thesis of this page expressed as a statistic, and it understates it, because it counts only one of several available reroutes.
What actually stops a laser procedure — and it is consistently the same two things
| Reason | 2007–2012 series (all ages) | 2022–2023 series (under 45) |
|---|---|---|
| Abnormal corneal topography | 34.3% | 43.5% |
| Insufficient corneal thickness | 23.1% | 24.5% |
| Correction too high for the tissue available | also common | 20.7% (severe myopia) |
| Severe dry eye | also common | — |
| Cataract or other finding changing the question | also common | — |
Two independent populations, two continents, eleven years apart, different screening technology. The top two reasons and their approximate rank order are the same in both. Second column: Moshirfar M et al., Evaluating the rate and causes of non-candidacy after LASIK screening, Cureus 2025;17(6), DOI 10.7759/cureus.86618.
That agreement is worth dwelling on, because it means the likely reason is knowable in advance. Both dominant findings are measurements — a thickness in microns, a map of curvature — and both are obtainable at home, months before anyone books a flight. The second series also published the underlying numbers behind the verdict: among patients under 45, those declined had measurably thinner corneas than those accepted (526.4 ± 33.6 µm against 548.8 ± 29.0 µm) and measurably steeper ones (K2 44.7 ± 1.7 D against 43.9 ± 1.6 D). These are not judgement calls about your suitability as a person. They are two numbers off a machine.
The five things “no” can mean, and where each one leads
This is the part that does not exist anywhere else in English, as far as we can find. Aggregator and clinic material does raise the scenario, but it resolves it into advice about choosing a clinic that has a policy — a transparent quote should specify what happens if screening shows you are not a candidate after arrival. That is advice to ask a question. Nobody publishes the answer. Here is the map.
| What was found | What it rules out | What it does not rule out | Where that goes |
|---|---|---|---|
| Cornea too thin for the correction | LASIK, usually SMILE | Surface ablation; an implanted lens | TransPRK or EVO ICL |
| Topography the surgeon will not cut | All flap and lenticule procedures | An implanted lens, if the interior measures well | How EVO ICL works |
| Correction beyond the laser's range | Laser correction at that power | An implanted lens — this is its classic indication | EVO ICL, and what it costs |
| Prescription still moving, or cornea reshaped by lenses | Nothing permanently | Everything, later | Washout before a workup · Stability |
| Tear film too poor to operate on today | Surgery until it is treated | Surgery after treatment, usually | Dry eye and refractive surgery |
| A corneal or other eye condition identified | Refractive surgery, for now | Ordinary ophthalmic care, which is the point | Out of scope here — this site covers refractive surgery only |
Read down the third column. In five of the six branches something remains available, and in one of them — the unstable prescription — nothing is ruled out at all, only postponed. This is why the useful question to ask in the room is not “why not?” but “which of these is it?” The reasons have very different consequences, and a patient who hears only the word “no” walks out without knowing which conversation they were in.
One reroute is deliberately absent from that table as a link: a thin cornea combined with high myopia is its own decision with its own arithmetic, and it has a dedicated page on this site that we are not linking to from here for reasons of an ongoing measurement rather than relevance. Search the resources index for thin corneas if that is your situation.
Why a Chinese centre may decline a cornea that passed at home
This happens, it surprises people, and it is not a sign of excessive caution or of a hidden agenda. Three things are going on.
First, the questions are different. An optometrist establishes your prescription and checks the health of your eye. A refractive workup asks a predictive question — how will this cornea behave once tissue is removed from it — which the sight test does not attempt and is not equipped to answer. A cornea can be entirely healthy and still be a poor candidate.
Second, the instruments are different and they have improved. Modern screening combines tomography with biomechanical measurement, and the sensitivity of that combination is part of why recent non-candidacy figures run higher than older ones — the authors of the 2025 series say so themselves, attributing their high rate to rigorous criteria, more sensitive diagnostics and the wider range of alternatives now available to route people to. A higher refusal rate for a named procedure, in a world with more procedures, is not the same as more people being turned away.
Third, and specific to China: there is national screening guidance behind the decision. The refractive-surgery group of the Chinese Medical Doctor Association's ophthalmology branch and the corneal-disease group of the Chinese Medical Association's ophthalmology branch publish consensus opinion on the early screening and diagnosis of keratoconus, framed explicitly as the basis for preoperative evaluation in corneal refractive surgery. A Chinese surgeon declining on an early topographic pattern is following a published national position rather than improvising. That is worth knowing in the room, because it changes what a second opinion is likely to say.
The money, and what this page will not pretend to know
This is where most writing on the subject either goes vague or goes quiet, so here is the boundary drawn explicitly. We publish no refusal rate for any partner hospital and no refund policy, because we hold neither figure. Inventing either would be worse than the silence it replaced — a reassuring number we cannot stand behind is exactly the kind of thing a reader would act on.
What can be set out is the structure of the exposure, which splits cleanly in two.
The medical side is small and negotiable. The workup is a consultation; the surgical fee attaches to surgery. The questions with real answers are: what the workup is charged at if nothing follows; what happens to a deposit when the reason is a clinical finding rather than a change of mind — those two cases are routinely treated differently and the distinction is usually the one that decides the money; and whether a rerouted procedure is held at the price you were quoted. That last one has teeth, because reroutes move in both directions. TransPRK is the cheapest line on the price table at 1,000 to 1,500 US dollars and EVO ICL the dearest at 3,800 to 4,800, both researched July 2026, against 1,200 to 1,800 for Femto-LASIK. Being rerouted from LASIK to ICL is not a scheduling change; it is a different budget.
The travel side is larger and nobody can waive it. Flights, hotel and leave are spent whatever the verdict. That asymmetry — a small, discussable clinical exposure against a fixed, non-refundable travel exposure — is the entire argument for settling candidacy before the tickets are bought. It is also why this question matters far more to you than to a domestic patient, who loses an afternoon.
What to have resolved before you book the flight
- Send corneal tomography and a pachymetry reading in advance. These are the two measurements behind the two commonest refusals. They are available in most countries, they are portable, and they convert the biggest unknown in the trip into something answerable from home.
- Send a refraction with a date on it, and an older one if you have it. Stability is judged from change over time, so one current reading answers half the question. Two readings a year or two apart answer all of it.
- Say what you wear and when you stopped. Rigid and overnight lenses reshape the cornea and the required washout is far longer than most people are told. A workup done too soon measures the lens, not the eye — and that is a wasted trip caused by a scheduling detail rather than by your eyes.
- Ask the reroute question before you ask the price question. “If I am not a candidate for LASIK, what would you propose instead, and what would that cost?” An answer to that, in writing, before travel, removes most of the financial surprise from the worst realistic day.
- Ask what is charged if no surgery follows, and get it in writing. Separate the clinical-finding case from the changed-my-mind case explicitly, because they are usually treated differently and the difference is the money.
- Treat a favourable pre-read as very likely, not as a promise. The examination on the day is done by the person who will operate, on their own machines, and it governs.
Questions people actually ask
What happens if I fly to China and the surgeon says I am not a candidate?
In most cases you are not sent home with nothing; you are moved to a different procedure. The reasons people are found unsuitable for LASIK are, overwhelmingly, reasons specific to LASIK — a cornea that is too thin to take a flap and an ablation, or a topography map the surgeon will not cut into. Neither of those rules out surface ablation such as TransPRK, and neither rules out an implanted lens such as EVO ICL, because those procedures put the correction somewhere else. So the realistic outcomes on the day are: the same operation as planned, a different operation at a different price, a recommendation to wait and re-measure, or — least often — a finding that routes you out of refractive surgery altogether and into ordinary ophthalmic care. The last of those is the only one that is genuinely a no, and it is the rarest. What decides which of them applies is the operating surgeon, after the measurements, and not this page.
How likely is it that I will be turned down?
Nobody can give you an honest personal number, and this site does not publish one. What exists is clinic-level screening data, and it needs reading carefully because the headline figures are misleading for a traveller. A 2025 review of 648 consecutive LASIK evaluations reported an overall non-candidacy rate of 69.4% — a frightening number until you look at what drove it, which was presbyopia: emmetropic presbyopia 36.9% and hyperopic presbyopia 25.6%, both of them findings in people over 45 who no longer have the short-sightedness LASIK is for. Restricted to patients under 45, the same study's reasons were abnormal topography 43.5%, corneal thinning 24.5% and severe myopia 20.7% — a different distribution about a different problem. An older and larger series, 1,067 consecutive candidates screened at a single centre between 2007 and 2012, is the better guide to the question you are actually asking: 38.4% did not go on to have surgery, but only 12.6% of the total were judged to have contraindications. The gap between those two figures is people who chose not to proceed, not people who were refused.
Why would a Chinese hospital refuse a cornea that my optometrist at home said was fine?
Because they are answering a different question with a better instrument. A high-street sight test establishes your prescription and the health of your eye; it does not attempt to predict how your cornea will behave after tissue is removed from it. The refractive workup does, and it does so with tomography, biomechanical measurement and — in Chinese practice specifically — against national screening guidance for early keratoconus that the refractive-surgery and corneal-disease groups of the Chinese medical associations publish precisely to underpin preoperative evaluation. A pattern that is invisible on a routine examination and harmless if left alone can still be a reason not to cut, because the concern is not what the cornea is doing now but what it would do afterwards. It is also why the same eye can be accepted by one surgeon and declined by another: the thresholds are judgements about acceptable risk, not a pass mark. Being declined on this basis is a statement about one operation, not a diagnosis.
Does a refusal mean something is wrong with my eyes?
Usually not, and this is worth separating carefully because the anxiety attached to the word 'refused' does not match what most refusals mean. The two commonest findings — a thin cornea and an irregular topography — are descriptions of the shape and thickness of a piece of tissue. A cornea at the thin end of normal is not diseased; it is simply a cornea with less material to spend on an ablation, which is an arithmetic problem rather than a health problem. An unusual topography is a different matter in that it sometimes is the earliest sign of a condition, which is exactly why it is looked for — but the majority of maps that stop a laser procedure are not a diagnosis of anything and do not require treatment. The small minority that do are the reason the screening exists, and finding one is the workup working rather than failing. If a genuine corneal condition is identified, that is ophthalmic care rather than refractive surgery, and it belongs with a different kind of service to this one.
What are the actual reasons people get turned down, in order?
Two findings dominate, and they do so consistently across very different populations and eleven years apart. In the 2007–2012 single-centre series, abnormal corneal topography accounted for 34.3% of exclusions and low or insufficient corneal thickness for 23.1%. In the 2022–2023 series, among patients under 45, abnormal topography accounted for 43.5% and corneal thinning for 24.5%. That agreement between two independent corpora is the most useful thing in the screening literature for someone planning a trip, because it means you can anticipate the likely reason rather than being blindsided by it. Behind those two come a correction too high for the available tissue, significant dry eye, an unstable prescription, and less commonly cataract or another finding that changes the question entirely. Note that these categories overlap — one person can be counted under more than one reason — so the percentages are not shares of a pie and do not sum to a hundred.
Can I find out before I fly, instead of after?
To a large extent, yes, and this is the single most useful thing on this page. The measurements that decide candidacy are ordinary tests available in most countries: corneal tomography or topography, a pachymetry reading for thickness, and a stable refraction. If you obtain those at home and send them before you travel, a surgeon can tell you what is likely, and a centre that will not look at them before you book is telling you something about how it operates. What a pre-travel read cannot do is commit anyone. The examination on the day is done on different machines by the person who will operate, and an assessment made from a file is a probability rather than a decision. Treat a favourable pre-read as removing most of the uncertainty rather than all of it, and treat an unfavourable one as a reason to change the plan while changing it is still free.
What am I financially exposed to if I am turned down after arriving?
Honestly: that depends entirely on terms you should get in writing before you fly, and this site does not publish a refund policy because it does not hold one to publish. What can be said is which questions have answers worth having. Ask what the workup itself costs and whether it is charged separately if no surgery follows. Ask what happens to any deposit if the reason for not proceeding is a clinical finding rather than a change of mind — those two cases are often treated very differently and the distinction is usually the one that matters. Ask whether a quote for a rerouted procedure is held at the price you were originally given, since some reroutes cost more and some cost less. And note the exposure that no clinic controls: flights, accommodation and leave are yours either way. That is the real reason to resolve candidacy before booking rather than after.
If I am refused for laser, is EVO ICL automatically an option?
It is often the option, but it is not automatic and it should not be presented as a consolation prize. An implanted lens sidesteps the two commonest reasons for laser refusal, because it does not remove corneal tissue and does not care how thin the cornea is — which is precisely why high myopia and thin corneas are the classic route to it. But it has its own candidacy requirements, measured on the interior of the eye rather than its surface, and a patient can fail those instead. It is also a different operation at a different price: the standard partner-hospital range for EVO ICL is 3,800 to 4,800 US dollars, researched July 2026, against 1,200 to 1,800 for Femto-LASIK and 1,000 to 1,500 for TransPRK. So a reroute from laser to ICL is a larger decision than a change of schedule, and it is worth knowing the possibility exists before the day rather than being asked to decide on it in a consulting room in a foreign country. Whether it is appropriate for your eyes is determined by the operating surgeon.
I was told to wait and come back. Is that a refusal?
No, and it is a meaningfully better outcome than it feels like. A recommendation to wait is normally attached to something that is changing and can be allowed to settle: a prescription that has moved in the last year or two, a cornea reshaped by rigid or overnight contact lenses that has not returned to its own form, or a tear film that would do better with treatment first. In each of those the eye is not being ruled out; the measurement is being called unreliable, and operating on an unreliable measurement is how people end up needing a second procedure. The practical question to ask is what specifically has to change, how it will be measured, and how long it usually takes — because that answer converts an indefinite wait into a date you can plan a trip around. It is also the branch where a pre-travel read pays for itself most obviously, since almost every waiting reason is visible from home.
