Experience the world’s most advanced and safest keratopigmentation procedure at Kaşkaloğlu Eye Hospital. Permanently, safely, and aesthetically change your eye color.
Keratopigmentation is a highly specialized and sophisticated ophthalmological procedure designed to permanently change the apparent color of the eye. The technique involves the precise placement of a biocompatible, medical-grade pigment into the cornea—the clear, protective outer layer at the very front of the eye. This pigment creates a colored layer that masks the natural color of the iris, which lies behind the cornea, resulting in a new, permanent eye color. FLAAK, which stands for Femto Laser Assisted Annular Keratopigmentation, is the most advanced and safest evolution of this technique. Unlike older, manual methods that relied on needles, the FLAAK procedure utilizes an ultra-precise femtosecond laser to create a perfectly uniform, circular micro-tunnel within the cornea. This bladeless, computer-guided step ensures unparalleled accuracy, consistency, and safety.
When considering a permanent eye color change, understanding the differences between available methods is critical to making a safe and informed decision. The fundamental advantage of FLAAK Keratopigmentation lies in where the procedure takes place. It is an **extraocular (surface) procedure, confined entirely to the cornea**. This distinguishes it from artificial iris implants or laser iris depigmentation.

Meet FLAAK Pro, the modern standard for permanent eye color change. This minimally invasive procedure is distinguished by its superior safety profile and efficiency. Using advanced femtosecond laser technology, a microscopic channel is created within the cornea, into which a special biocompatible pigment is placed. The procedure is performed entirely on the surface of the eye without touching the internal structures, offering a much safer alternative to risky surgeries like iris implants.
