Corneal tattooing is a cosmetic or therapeutic procedure used to change the color or appearance of the cornea, the clear, front surface of the eye. It is often performed to address cosmetic concerns related to corneal scars, opacities, or irregularities that can result from injury, disease, or congenital conditions. The procedure involves applying a pigment to the cornea, which can help mask imperfections, reduce glare, and improve the aesthetic appearance of the eye. While primarily cosmetic, corneal tattooing can also provide psychological benefits to patients by restoring a more natural look to the affected eye. The procedure requires precision and is typically performed by an ophthalmologist or a highly trained specialist.
