LASIK Gone Wrong in Turkey: Malpractice, Corneal Ectasia & Legal Recourse

You were promised sharper vision. Instead, weeks or months after your LASIK procedure in Turkey, you're still squinting at road signs, seeing halos ring every headlight at night, or blinking through eyes that burn and water no matter how many drops you use. Maybe the clinic told you this was normal healing. Maybe they stopped answering your messages once you flew home.

That gap between what you were told and what you're living with is frightening, especially when the surgeon is in another country and follow-up care is suddenly your own problem to solve.

Here's what this piece will help you work out: whether what you're experiencing is a recognised, sometimes-unavoidable side effect of laser eye surgery, or a sign that something was done wrong, from skipped pre-operative testing to a cornea that was never suitable for LASIK. We'll cover the complications that raise genuine red flags, what Turkish law says about a surgeon's duty of care, and the practical steps open to you now.

The first question is the hardest, and the most worth getting right: is this a known complication, or actual malpractice?

Is this a known complication or actual malpractice?

Not every bad outcome after LASIK is malpractice. This is the hardest thing to sit with when your vision is worse than before, but it matters for whether you have a case at all.

The law, in Turkey as elsewhere, doesn't ask whether you're happy. It asks whether your care met a recognised standard.

What "standard of care" actually means

Standard of care is the level of skill and caution a reasonably competent refractive surgeon would have applied in the same situation. It covers screening you properly, telling you the real risks, and only operating if your eyes were suitable.

A surgeon who does all of that and still hits a known complication has generally met the standard. A surgeon who skipped a step that would have changed the decision has not.

Known risks that aren't negligence on their own

LASIK carries documented side effects that competent surgery cannot fully eliminate. Dry eye and visual disturbances, glare, halos, starbursts, are the most common.

The numbers are sobering even when everything is done right. Pooled data from the FDA's PROWL studies, reviewed in Clinical Ophthalmology, reported some visual disturbance in roughly 50–60% of patients at three months, around 35% with new dry eye, and symptoms worsening in about 27%. Overall dissatisfaction sat at 2–6%. A more recent review in the Journal of Refractive Surgery suggests severe dry eye now affects roughly 4–6%, partly because screening has improved. Experiencing one of these does not, by itself, mean someone failed you.

When a complication crosses the line

Negligence enters the picture when the problem traces back to a decision that fell short. The clearest examples:

• Skipped or inadequate screening, no corneal topography or thickness mapping before treatment.
• Ignored risk markers, abnormal topography or thin corneas signalling higher ectasia risk were missed or disregarded. The American Academy of Ophthalmology's Refractive Surgery guidance flags abnormal topography and a percent tissue altered of 40% or more as raising that risk.
• Operating on an unsuitable eye, leaving too little corneal tissue behind, below the suggested 250-micron residual stromal bed, which can destabilise the cornea.

Malpractice is a legal threshold backed by evidence. The distinction decides whether what happened to you is a recognised risk you consented to, or a failure someone is answerable for.

What are the warning signs of negligent LASIK care?

Most people who come to us don't have a diagnosis. They have a feeling that something was skipped, rushed or glossed over. That instinct is often correct, and the clearest evidence of negligent care usually sits in the process before the laser ever touched your eye.

Screening that was too thin

Safe LASIK depends on knowing your eyes in detail beforehand. A surgeon should map the surface of your cornea (corneal topography) and measure how thick it is, because both reveal whether your eyes can safely tolerate the procedure.

Treat these as red flags:

• No corneal topography or thickness scan was done, or you were never shown the results.
• You were screened and operated on the same day, leaving no time to review measurements properly.
• A risk factor was waved away. Peer-reviewed research by Randleman and colleagues ranks the strongest ectasia risks as abnormal topography, a thin residual cornea, young age, low corneal thickness and high myopia.

The American Academy of Ophthalmology's practice pattern recommends leaving at least 250 micrometres of cornea untouched beneath the flap and treats a percentage tissue altered (PTA) of 40% or more as raising ectasia risk. A surgeon who ignores those thresholds to fit a borderline eye is taking a chance with your sight, not yours.

Consent that wasn't really consent

Signing a form minutes before surgery is not informed consent. Proper consent means a real conversation about the risks, the alternatives (such as PRK or staying in glasses) and whether your specific eyes are suitable.

Booking models that work against you

Some medical-tourism packages are built around volume, not assessment. A law firm review of cross-border negligence cases notes that patients abroad are often booked without ever meeting the operating surgeon and with little time before surgery. Be wary if a coordinator (not a clinician) confirmed you were "fine for surgery", or if the price and date were locked in before any scan. None of these prove malpractice alone, but together they describe a system that skips the safeguards designed to protect you.

Corneal ectasia, dry eye and night vision problems: what should have been prevented?

Some complications after LASIK are bad luck. Others trace back to a screening step that should have caught the risk before the laser ever touched your eye. Telling those apart is where the negligence question begins.

Corneal ectasia and the screening link

Corneal ectasia is a progressive weakening and bulging of the cornea after surgery, and it can threaten your sight. Studies put the incidence at around 0.04% to 0.6%, appearing anywhere from a week to several years post-LASIK.

Here's the part that matters legally: the biggest risk factors are largely visible before surgery. A peer-reviewed review in Ophthalmology ranked abnormal preoperative topography and a thin residual cornea as the leading predictors, alongside young age and high myopia. The American Academy of Ophthalmology recommends leaving at least 250 µm of residual stromal bed and flags abnormal maps as a red line. A proper workup is designed to find exactly these signals.

Dry eye and night vision were supposed to be assessed

Persistent dry eye is one of the most common complications after LASIK. A systematic review on PMC listed predisposing factors a thorough clinic should flag in advance: pre-existing dry eye, meibomian gland dysfunction, thyroid eye disease, higher corrections and deeper ablations, most of which are knowable from your history and a slit-lamp exam.

Night vision halos and glare often follow over-correction or treating poor candidates. A 2016–2023 literature review suggests dry-eye impact has fallen as screening improved, with severe dry eye now reported in roughly 4–6% of cases. Better screening, better outcomes.

Expected experience versus a process failure

Not every difficult recovery is malpractice. The table below separates what's within normal limits from what points to a screening or planning lapse.

When a documented risk was visible beforehand and treatment went ahead anyway, that's the question a lawyer and an independent ophthalmologist will examine.

How does medical negligence law work in Turkey?

If a clinic in Izmir or Istanbul damaged your eyes, the case lives in Turkey. Your treatment happened there, the contract was signed there, and the surgeon is licensed there. Turkish law governs what went wrong, and Turkish courts are almost always where a claim is heard.

Why your home country's courts rarely help

Many people assume they can sue back home. In most cases it is difficult or unlikely. Home courts accept jurisdiction over overseas treatment only in narrow circumstances, and the applicable framework varies by country, EU residents operate under different cross-border rules than those from outside the EU. The International Bar Association and firms handling these disputes have noted that cross-border negligence rules are genuinely complex.

A frequently cited example is Clarke v Kaleciński [2022] EWHC 488 (QB), an English case involving cross-border cosmetic surgery, where the court had to untangle which court and which law applied. It illustrates a jurisdictional principle rather than an ophthalmic precedent. The lesson: don't assume your local lawyer can run this alone. You will likely need someone qualified in Turkish law.

Your rights as a patient in Turkey

Turkey has a formal patient-rights system. The Patient Rights Regulation dates from 1998, and Patient Rights Units were placed in public hospitals in 2004 to receive complaints, according to a study in the Balkan Medical Journal.

Under that framework you can complain about a clinician's conduct, and where a violation is found it can trigger an inspector, disciplinary penalties, a criminal complaint, or a civil lawsuit, as Turkish healthcare lawyers explain. These routes can run in parallel.

How fault and the standard of care are decided

To establish negligence you generally need to show the care fell below what a reasonably competent eye surgeon would have done, and that this failure directly caused your harm. That almost always rests on independent expert medical review: an appointed specialist examines your records, scans and surgical notes, and gives an opinion on whether the screening, treatment or consent fell short. Strong documentation makes or breaks this stage.

How long you have to act

Limitation periods under Turkish law vary depending on the legal basis of your claim, a Turkish-qualified lawyer should confirm the applicable deadline for your specific facts. This matters particularly with eye damage that can surface months after surgery. Have a lawyer confirm your deadline rather than guessing.

What should you document and do now?

Whatever your vision looks like right now, the most useful thing you can do is build a clear, dated record of your condition and how it differs from what you were promised. That record is what an independent expert, and later a lawyer, will work from.

Get an independent eye assessment at home

Book an examination with an ophthalmologist or refractive specialist who has no link to the treating clinic. Ask specifically for current corneal topography (a map of your cornea's shape and thickness) and a written clinical record describing your symptoms, vision and any diagnosis such as ectasia or dry-eye disease. This independent snapshot documents your outcome in neutral hands and, if you need ongoing care, is where it starts.

Secure every record from the Turkish clinic

You have a right to your own medical records. Request copies of everything in writing, and keep the request itself.

• Consent forms you signed, including any risk disclosures.
• Pre-operative measurements, corneal thickness, topography, prescription and the screening that decided you were a candidate.
• Operative notes describing the procedure performed and the laser settings used.
• All correspondence, including WhatsApp messages, emails and booking confirmations.

Pre-op measurements are often the heart of a refractive case. If your cornea was too thin or too irregular for the procedure you received, those numbers are where it shows.

Document the financial and personal cost

Keep receipts for the original surgery, travel and any corrective treatment or glasses since. Write down lost income, help you've needed, and the gap between the result you were sold and the one you live with. A short personal timeline of how your sight changed is valuable evidence.

Lodge a complaint, and speak to the right lawyer

Under Turkey's Patients' Rights Regulation you can complain to the health institution and to the Ministry of Health about staff conduct; serious violations can trigger an inspector and, in some cases, disciplinary or criminal steps (Gün + Partners). Note that JCI or ISO accreditation describes an institution's systems, not your individual surgeon's outcome (Turquie Santé).

Before you assume you have a case, or that you've missed your chance, have it assessed by a lawyer qualified to act on Turkish claims. The same applies to other eye procedures that have gone wrong. One conversation often clarifies more than weeks of worry.

Two things matter most right now. Book an independent eye assessment in your own country, ideally with a corneal specialist, and ask them to record your current measurements in full: topography, pachymetry, refraction, and corrected and uncorrected vision. This gives you a dated, objective snapshot taken by someone with no stake in the outcome.

At the same time, send a written request to the Turkish clinic for your complete file: pre-operative topography and corneal thickness readings, signed consent forms, operative notes, and any post-op records. Turkey's patient-rights framework may support your right to access these records; a lawyer qualified in Turkish law can advise on enforcing that request if the clinic does not respond.

Once you hold both sets of records, have them reviewed together by a lawyer qualified to handle claims in Turkey before you decide anything. Whether what happened was an accepted risk or a genuine failure of care is a question for the measurements, not for how the result feels, and you do not have to answer it alone.
