Is FLAAK keratopigmentation a safe procedure?

The FLAAK technique uses certified biocompatible pigments and a high-precision femtosecond laser. The pigment is placed within the thickness of the cornea: there is no surgery inside the eye (iris, lens, retina), unlike iris implants. Like any corneal surgery, it carries risks (dryness, glare, inflammation, infection), which Dr Gozlan explains during the consultation; the preoperative assessment is there to rule out eyes that should not be operated on. Dr Gozlan has operated on more than 1,000 patients.

Is the procedure painful?

The procedure is performed under local anesthesia with eye drops, which greatly reduce the eye's sensitivity: during the operation, you mainly feel pressure or contact. Pain or stinging is, however, common in the following hours and days: in a survey of 42 patients treated with the FLAAK technique (BMC Ophthalmology, 2023), 81% reported pain during or after the procedure. These symptoms were temporary in every case and had gone within 48 hours for about half of the patients.

How long does the operation last?

The procedure takes approximately 15 to 20 minutes per eye. It is performed on an outpatient basis — you go home the same day. Full recovery is achieved within 48 to 72 hours.

Can I choose any color?

We offer a palette of natural shades carefully selected to harmonize with each morphology and skin tone. During the initial consultation, Dr Gozlan will guide you toward the colors best suited to your face and aesthetic desires.

What are the eligibility criteria?

A prior ophthalmological consultation is mandatory. Contraindications include certain eye diseases (active glaucoma, severe keratoconus), pregnant or breastfeeding women, and immunocompromised patients. The recommended minimum age is 18 years. The complete preoperative assessment will precisely evaluate your eligibility.

Is the result permanent?

FLAAK keratopigmentation is designed to be permanent: the pigment is placed in the corneal stroma. The shade may change slightly during the first weeks as the pigments integrate into the tissue. In some cases a touch-up may be needed; this is discussed with you during the consultation.

What is the cost of the procedure?

FLAAK keratopigmentation costs €5,500 for both eyes, whatever color you choose, even if the procedure is done in two stages. This price includes the pre-operative consultation, the femtosecond laser procedure and certified pigments. On the day of the procedure, I give you your post-operative prescription, to take to a pharmacy, along with an eye colour change certificate to keep with your passport: when you next renew it, your new eye colour can be shown on it. For reference, the Neoris Eyes clinic list shows, as of October 2026, prices ranging from €5,500 to €10,000 in Europe, depending on the clinic and the country (source: Neoris Eyes clinic list).

What is the difference between FLAAK keratopigmentation and iris implants?

Iris implants are placed inside the eye; the American Academy of Ophthalmology (AAO) has described serious complications (glaucoma, cataract, corneal damage). With the FLAAK technique, the pigment is placed within the thickness of the cornea: there is no surgery inside the eye. It is corneal surgery, with its own risks, which are explained during the consultation.

Is it possible to return to one's natural color after the procedure?

FLAAK keratopigmentation is designed to be permanent. The pigment integrated into the corneal stroma cannot be removed by a simple procedure. This is why a thorough and considered consultation beforehand is essential before any decision.

Does FLAAK keratopigmentation affect vision?

The pigments are placed in the periphery of the corneal stroma, leaving the central optical zone clear. The technique is designed to change only the apparent color of the eye. Like any corneal surgery, it carries risks (including glare), which are explained during the consultation. Regular eye check-ups remain recommended.

The question of insurance coverage is often one of the first concerns for patients considering FLAAK keratopigmentation. Given such a specialized ophthalmic surgical procedure, it is entirely legitimate to understand what social security covers, what supplementary health insurance may reimburse, and what overall budget to plan for. In this article, Yoni Gozlan, M.D. provides clear, transparent, and comprehensive answers regarding the cost and insurance coverage of FLAAK keratopigmentation.

Is FLAAK Keratopigmentation Covered by French Social Security?

The answer is straightforward: no, FLAAK keratopigmentation is not covered by the French Social Security system. This surgical technique, which involves permanently changing the color of the iris by implanting pigment into the corneal stroma, is classified as a cosmetic procedure by French health authorities. As such, it falls outside the scope of coverage provided by the national health insurance system.

In France, Social Security only reimburses medical procedures deemed medically necessary — that is, those that address a confirmed pathology or a specific therapeutic indication. However, FLAAK keratopigmentation, in the vast majority of cases, is performed to fulfill an aesthetic desire — permanently changing eye color. Even though the procedure is carried out by a qualified Ophthalmic Surgeon such as Yoni Gozlan, M.D., its non-therapeutic nature excludes it from any reimbursement under the mandatory national health insurance scheme.

There are nevertheless exceptional situations in which a medical indication may justify partial coverage, particularly in cases of aniridia (absence or insufficiency of the iris), ocular trauma, or a pathology affecting the integrity of the iris. In these specific cases, a request for exceptional coverage can be submitted for review, but this remains rare and is subject to the assessment of the Primary Health Insurance Fund (CPAM).

Can Supplementary Health Insurance Step In?

Supplementary health insurance providers generally follow the same logic as Social Security: they only reimburse procedures that are already covered by the mandatory national health insurance, or procedures specifically mentioned in your policy. Since FLAAK keratopigmentation is not covered by Social Security, the vast majority of supplementary insurers will not contribute to the costs incurred either.

However, it is always advisable to review your insurance policy or contact your insurer directly before any procedure. Some premium contracts include allowances for cosmetic surgery or ocular surgery that could, in rare cases, offer partial coverage. This preliminary check costs nothing and may yield pleasant surprises.

In summary, you should approach FLAAK keratopigmentation with the understanding that you will bear the full cost personally. This is why transparency regarding the fees charged by Dr. Gozlan at Centre Laser Victor Hugo, in Paris 16th arrondissement, is a priority in the care and guidance provided to each patient.

What Is the Overall Cost to Expect for FLAAK Keratopigmentation?

The cost of FLAAK keratopigmentation is a significant investment that should be anticipated in its entirety. Several elements factor into the total budget:

The preoperative consultation: a comprehensive ophthalmological assessment is essential before any surgical decision. This step allows Yoni Gozlan, M.D. to evaluate your eligibility for FLAAK keratopigmentation and to rule out any contraindications.
The surgical procedure fee: the cost of the procedure itself represents the bulk of the budget. The fee is fixed: €5,500 for both eyes, regardless of the color chosen.
Additional examinations: certain specialized tests may be required before the procedure to ensure the safety of the corneal pigmentation surgery.

It is important not to focus solely on the listed price of the surgical procedure, but rather to consider the entirety of this care pathway. During your consultation with Dr. Gozlan, a detailed estimate will be provided, in accordance with the regulations governing cosmetic surgery procedures. This document will give you a precise and complete overview of the total cost before you commit.

Why Invest in FLAAK Keratopigmentation Despite the Lack of Coverage?

The absence of Social Security coverage does not diminish the medical value or the positive impact of FLAAK keratopigmentation on patients' quality of life. Many patients report a profound change in their self-confidence and overall well-being after the procedure.

FLAAK keratopigmentation is a permanent surgical procedure, performed in a rigorous medical setting, by a certified specialist. Unlike colored contact lenses — whose unsupervised use can lead to serious ocular complications — FLAAK keratopigmentation offers a lasting, natural result when performed by an experienced Ophthalmic Surgeon.
