Is FLAAK keratopigmentation a safe procedure?

Yes. The FLAAK technique uses certified biocompatible pigments and a high-precision femtosecond laser. It does not touch the internal structures of the eye (iris, lens, retina), making it much safer than iris implants. Thousands of procedures have been performed with excellent results worldwide.

Is the procedure painful?

No. The procedure is performed under local anesthesia using eye drops. The patient feels no pain during the operation. In the following days, mild discomfort or light sensitivity may be felt — it generally disappears within 48 to 72 hours.

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, with rigorous post-operative follow-up by Dr Gozlan.

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 25 years. The complete preoperative assessment will precisely evaluate your eligibility.

Is the result permanent?

Yes, the result is permanent. The pigment is deposited in the corneal stroma and does not migrate. No regular touch-ups are needed. A slight change in shade may occur in the first few weeks as the pigments fully integrate into the tissue — this is perfectly normal and expected.

What is the cost of the procedure?

FLAAK keratopigmentation is offered at the most competitive price worldwide. Contrary to what one might think, a competitive price does not mean lower quality: the surgery, the femtosecond laser, and the certified biocompatible pigments are strictly identical from one clinic to another. What differs is the strategy: Dr. Gozlan prioritises a high volume of procedures and an optimised organisation to make the intervention accessible without any medical compromise.

What is the difference between FLAAK keratopigmentation and iris implants?

Iris implants are placed inside the eye and present serious risks: glaucoma, cataracts, corneal damage. The FLAAK technique acts only on the superficial corneal stroma, without ever touching internal structures. It is considered significantly safer than iris implants.

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?

No. The pigments are deposited in the peripheral corneal stroma, leaving the central optical zone intact. The technique only modifies the perceived color of the eye, without affecting visual functions. Regular ophthalmological check-ups are nevertheless recommended.

The question of pain is one of the first concerns patients raise when considering ophthalmic surgery. FLAAK keratopigmentation is no exception. It is entirely natural to wonder about the sensations experienced during and after the procedure, and to seek reassurance before taking the step. Yoni Gozlan, M.D., a specialist in FLAAK keratopigmentation in Paris, answers all of your questions here with transparency and care, so that you can make your decision with complete confidence.

Pain During the FLAAK Keratopigmentation Procedure: What You Need to Know

One of the most common concerns among patients relates to the pain experienced during the procedure itself. The good news is that FLAAK keratopigmentation is performed under topical anesthesia using eye drops, which eliminates any painful sensation during the procedure. These anesthetic eye drops, instilled directly into the eye before the operation begins, produce rapid and effective numbing of the ocular surface.

Thanks to this anesthetic protocol, the patient experiences no sharp pain while Yoni Gozlan, M.D. performs the FLAAK keratopigmentation. The eye is fully anesthetized, ensuring optimal comfort throughout the entire procedure. There is no need for general anesthesia, which represents a considerable advantage in terms of safety and recovery.

Sensations Experienced During the Procedure

Although pain is absent, it would be inaccurate to say that the FLAAK keratopigmentation procedure takes place in complete insensibility. Some patients describe particular sensations that may be surprising without being unpleasant. Here is what you might feel:

Slight pressure on the eye during the positioning of surgical instruments
A contact sensation or light brushing on the corneal surface, with no associated pain
Mild discomfort from keeping the eye open, facilitated by a specially designed device
Temporary glare caused by the operating room lighting
A slight vibration or mechanical sensation during the creation of the intrastromal tunnel characteristic of the FLAAK technique

These sensations are entirely normal and in no way indicate that the procedure causes suffering. FLAAK keratopigmentation is designed to be as comfortable a procedure as possible for the patient, and Dr. Gozlan personally ensures that every step is carried out under the best possible conditions.

Post-Operative Discomfort After FLAAK Keratopigmentation

Once the local anesthesia has worn off, in the hours following FLAAK keratopigmentation, some patients may experience moderate discomfort. It is important to clearly distinguish this temporary discomfort from actual pain: in the vast majority of cases, the post-operative course following FLAAK keratopigmentation is well tolerated and does not require strong pain medication.

The most commonly reported symptoms in the first hours and days following the procedure include:

A stinging or mild burning sensation in the operated eye, comparable to that experienced after exposure to chlorine or prolonged screen time
Excessive tearing, a natural reaction of the eye to the surgical procedure
Increased sensitivity to light (mild to moderate photophobia) during the first few days
Temporary eye redness related to corneal healing
Slightly blurred vision during the first few days, as the cornea regains its optimal transparency

How to Manage Discomfort in the First Few Days

The immediate post-operative period after FLAAK keratopigmentation typically lasts two to four days, during which discomfort is most noticeable. The care protocol established by Yoni Gozlan, M.D. at the Clinique Laser Victor Hugo, in the 16th arrondissement of Paris, includes several measures to facilitate this recovery phase:

Anti-inflammatory and antibiotic eye drops, prescribed to prevent any infection and reduce local inflammation
Artificial tears applied regularly to hydrate the ocular surface and soothe sensations of dryness or burning
Wearing protective glasses to avoid any accidental contact with the operated eye
Avoiding dusty, smoky, or air-conditioned environments during the first week
Mild analgesics (paracetamol) may be taken if discomfort warrants it, although most patients do not feel the need

FLAAK keratopigmentation is a minimally invasive technique that preserves the integrity of the corneal surface. Unlike some more invasive ocular surgeries, it does not require sutures, and healing occurs naturally and progressively. The majority of patients operated on by Dr. Gozlan report a rapid recovery and a return to daily activities within just a few days.

FLAAK Keratopigmentation: A Procedure Designed for Patient Comfort

FLAAK keratopigmentation was developed with particular attention to the patient experience before, during, and after the procedure. Since the beginning of his career in this specialty, Yoni Gozlan, M.D. has continuously refined his surgical protocol to minimize any unnecessary discomfort and maximize the safety of each FLAAK keratopigmentation procedure.

It is essential to remember that pain tolerance is subjective and varies from one individual to another. Some patients describe a nearly imperceptible procedure, while others are more aware of the tactile sensations mentioned above. In all cases, the medical staff present in the operating room are trained to reassure and support the patient throughout the entire FLAAK keratopigmentation procedure.

It is also important to emphasize that preoperative anxiety can amplify the perception of sensations. This is why Dr. Gozlan places paramount importance on the preoperative consultation, during which all of your questions receive a clear and personalized response. This transparency is an integral part of the approach to FLAAK keratopigmentation as practiced in Paris.

In summary, FLAAK keratopigmentation is a well-tolerated procedure, performed under topical anesthesia with eye drops, without significant pain during the operation and with only moderate and transient post-operative discomfort in the first few days. Millions of people around the world undergo similar techniques and leave satisfied with their results. FLAAK keratopigmentation follows this same philosophy of respectful and effective care.
