Eyeball tattooing or sclera tattooing is a practice of colouring the sclera or white of the eye permanently. It is performed by injecting the ink with a needle underneath the top layer of the eye onto the sclera. The ink then slowly spreads to cover all the parts of the sclera. This procedure is carried out by only a few tattoo artists around the world. This procedure is permanent and is non-reversible.
There are many risk factors that one must through for eyeball tattooing. Like other many other procedures, eyeball tattooing has its pros and cons. According to the Royal Australian and New Zealand College of Ophthalmologists, they consider eyeball tattooing a major risk procedure and recommended that it can only be performed by a doctor when medically indicated, for example, if a person has some specific eye abnormalities. RANZCO also advises not to go under the needle, as for them they view it as an enormously dangerous and also feel that it is an unnecessary procedure. There are several health risks associated with undergoing eyeball tattooing. They often range from mild risks such as a mild irritation of the eye to many severe risks such as blindness.
However, the long term risks to the eyeball are still unknown. It is also very important to note that it is doubtful that the techniques that are used to remove skin tattoos could be used on the eyeball. Removal of an eyeball tattoo is likely to be impossible. Therefore, it would be beneficial not to opt for eyeball tattooing.
