    In this video from Dr. Osher's Video Journal of Cataract and Refractive Surgery, Dr. Jorge Alio demonstrates the functional and cosmetic benefits of femtosecond-assisted keratopigmentation (FAK), or corneal tattooing, for eye disorders related to iris defects.

    A patient presents with essential iris atrophy due to iridocorneal endothelial syndrome, and complains of photophobia, monocular diplopia, and night glare. After the surgeon removes residual pupillary tissue, the Intralase laser is used to create hemispheric tunnels in the stroma, through which custom micronized mineral pigments are then injected. Following cosmetic correction of the anatomic defect, the patient's visual disturbances also resolve.
