Several different methods exist today. Generally in most procedures, the dyeing agent is applied directly to the cornea. The tattoo artist then inserts the needle into the eye to inject the dye into the cornea. All tattoo artists agree that the tattoo should be injected intramellarly or laterally, which provides an appearance of a uniform color and minimizes the chance of an irritable eye. It is worth noting that some individuals may refer to the tattoo artist as physicians, however, that is not an accurate statement to be made. Therefore, one must be careful in what they read and write on the internet. Please be advised, this is a tertiary source and must be treated as such.
