FLAAK (Femtosecond Laser-Assisted Artificial Keratopigmentation) is a modern surgical technique used for changing eye color. It involves the use of a femtosecond laser to create precise incisions in the cornea, into which colored pigment is injected. This method is considered safer and more predictable compared to earlier techniques because the laser allows for high precision, minimizing damage to the surrounding tissue. Here’s how FLAAK works: Laser Incision: A femtosecond laser creates microchannels in the corneal stroma (the middle layer of the cornea). These channels are made with extreme precision, reducing risks. Pigment Injection: Biocompatible pigments are then injected into these channels to change the apparent color of the eye. The pigment remains trapped within the corneal layers, providing a semi-permanent color change. Customization: The technique allows for customization of the eye color based on patient preferences and can be used to correct congenital or acquired conditions like corneal opacities, as well as for cosmetic reasons. FLAAK has been praised for being minimally invasive, with a relatively quick recovery period. However, as with any surgical procedure, there are risks, including infection, inflammation, or issues related to the long-term stability of the pigment. It is considered an alternative to other techniques like traditional keratopigmentation, which involves manually creating incisions or depigmentation techniques that use lasers to remove natural pigment. Keratopigmentation for therapeutic and eye color change (FLAAK) operations are performed in our hospital. Son Güncelleme 18 November 2025 Saat 09:42 am
