FLAAK Eye Color Surgery (Keratopigmentation) – Operating Method

What is FLAAK Surgery (Keratopigmentation)?

FLAAK surgery, also known as keratopigmentation, is a procedure to modify the corneal color by implanting pigments. This is typically done for cosmetic or therapeutic reasons, such as to mask corneal scars or treat light sensitivity. It involves creating precise channels in the cornea for stable pigment placement.

The surgical method presented on this website was developed by Dr. Francis Ferrari, a pioneer and leader in eye color change by FLAAK (keratopigmentation)

In 2013, Dr. Ferrari, an ophthalmic surgeon who graduated from the renowned University Clinic of Tübingen in Germany, and who specializes in refractive surgery, achieved a world first:

“Changing eye color by FLAAK (keratopigmentation) for aesthetic purposes.”

Since then, surgeons on the Neoris platform have carried out thousands of operations, representing almost 90% of all operations performed worldwide.

There are two other methods for changing the color of the eyes: colored implants and laser depigmentation of the iris. The first technique is extremely dangerous (many cases of blindness have been reported) and the second technique is not very effective. It can also lead to complications, such as glaucoma.

The operation

A controlled operation Annular FLAAK (keratopigmentation) is a surgical procedure in which a circular micro-tunnel is made in the cornea and pigment is applied to cover the natural eye color.

A painless and quick operation The procedure is performed under local anesthesia and lasts for one hour. It does not affect the internal structures of the eye and does not require an eye implant.

A safe operation thanks to 3 rules of caution The procedure : – requires the use of a laser adapted and programmed for this operation. – requires the surgeon to have the essential instrument to facilitate a highly precise surgical gesture. – requires proven dyes.

Today, thousands of patients have been successfully operated on in this way, without any serious complications.

An innovative operation

The surgeons on the Neoris platform are constantly refining their surgical techniques.

It is also possible to enhance or reduce the intensity of the color initially chosen. This is called touch ups.

Thanks to new advances, it is now possible to regain one’s natural color, and the operation is now reversible.

What is Keratopigmentation?

Keratopigmentation is an advanced surgical technique offered in several refractive surgery clinics to allow a permanent eye color change by implanting biocompatible pigment. Ophthalmologists perform this eye color change operation using a Femtosecond Laser, creating micro-tunnels in the corneal tissue to place the pigment safely. 

This surgical procedure follows strict medical procedures to ensure the highest environmental and quality standards, providing a natural color change that can last a lifetime. By modifying eye color, the FLAAK treatment offers patients an aesthetic alternative to contact lenses or colored lenses and can enhance aesthetic appearance for both therapeutic purposes and cosmetic reasons.

What Does FLAAK Mean?

FLAAK stands for Femto Laser Assisted Annular Keratopigmentation. This color change procedure relies on a femtosecond laser, enabling precise surgical techniques for the safe placement of pigments in the corneal tunnels. Unlike retinal surgery or iris implants, this procedure achieves a natural color that preserves initial radiance and maintains the aesthetic appearance of the eye. FLAAK ensures a stable and lasting color change that adapts to cosmetic purposes and avoids the need for contact lenses or other methods of altering eye color.

How Does Keratopigmentation Surgery Work?

Keratopigmentation follows several steps to ensure a natural and lasting result:

  1. Preparation: The keratopigmentation surgical procedure begins with ophthalmologists administering anesthetic eye drops or simple drops to numb the eye. The surgeon uses a femtosecond laser to create micro-channels in the cornea, preparing the eye to receive the pigment without damaging surrounding tissue.
  2. Pigment Introduction: A biocompatible pigment is introduced, providing a permanent new color. This color change operation modifies the eye’s appearance with a natural-looking color, available in a range of colors such as hazel or blue.
  3. Stabilization: The pigment spreads evenly, creating a durable change in iris color. The procedure’s minimally invasive approach helps avoid potential complications, preserving vision quality without the need for contact lenses or colored lenses.

This precise process offers a permanent color change without the need for contact lenses, providing patients with a stable, aesthetic alternative.

What Are the Benefits of the Keratopigmentation Technique Developed by Dr. Ferrari?

The FLAAK technique developed by Dr. Ferrari offers numerous advantages for patients seeking a color change operation for aesthetic or cosmetic purposes. By utilizing the femtosecond laser, this medical procedure minimizes risks of infection and vision loss, while biocompatible pigments assure a stable and natural color change. This treatment is ideal for individuals who prefer a permanent change in eye color without needing contact lenses or dealing with the risks associated with retinal or corneal transplants. 

Our keratopigmentation method adheres to high safety standards, providing an appealing, harmonious appearance, whether for cosmetic reasons or as a corrective approach for iris defects.

Does Keratopigmentation Improve Vision?

While effective for aesthetic purposes, the FLAAK keratopigmentation technique is not designed to improve vision. Unlike LASIK or other refractive surgeries that correct vision, this surgery focuses solely on cosmetic enhancement or therapeutic purposes for people seeking a new eye color or who have eye disorders. 

It does not alter visual capacity, nor does it address vision loss from conditions like glaucoma. However, by offering a stable color through safe medical procedures, keratopigmentation can satisfy a range of personal preferences without impacting vision.

What Are the Side Effects of a FLAAK Procedure?

As with any surgery, keratopigmentation may cause mild side effects. Patients may experience temporary irritation, sensitivity to light, or dryness, often relieved with eye drops or wearing sunglasses post-procedure. These effects typically subside as the healing process progresses, and the surgery’s use of biocompatible pigments and stringent safety standards helps minimize risks like corneal infection.

Are There Any Risks Associated with the Femtosecond Laser?

While the femtosecond laser is highly precise, rare complications can occur, especially if additional implants or color alterations are attempted later. However, adhering to strict clinical ophthalmology standards and choosing a qualified surgeon can reduce these risks. By using biocompatible pigments in the procedure, the chances of corneal infection or adverse reactions affecting vision are minimized.

Is Eye Pigmentation Not Recommended for Certain Individuals?

Not everyone is suited for keratopigmentation. Even only for aesthetic purposes, this color change procedure might not be ideal for those who have undergone previous surgeries, such as LASIK or retinal surgery, due to potential unpredictable results. Patients with lighter eyes, traumatic iris conditions, or specific color preferences may require additional evaluation to determine the best option for achieving their desired aesthetic appearance safely. An ophthalmologist will assess each case, ensuring that only those without high risk for complications pursue this treatment for a safe and effective color transformation.
