world's first eyeball tattoo
The technique was first described by Galen, who burnt the cornea with a heated stilleto, and applied either an iron or copper mixture, thereby making the cornea more transparent. In the 19th century, modern techniques were introduced to recreate the colour of the iris stroma, using Indian ink. Further research looked into the ways of stabilizing the pigment, and ways to apply these pigments to the eye.
BME, a magazine that deals with all kinds of body modifications, has in July 2007 covered this procedure as a way of decorative tattooing.
The freaky procedure was carried out to turn a body-art fan's eye blue.
And it took FORTY insertions of the needle to get the job done.
Volunteer Pauly Unstoppable, from Canada, has perfect vision but jumped at the chance to be the first punter.
See the toe-curling shots in the gallery below. But be warned - the pictures are very graphic.
Brave Pauly said he had full confidence in the team working on him - but urged people not to try it at home.
He added: "The procedure was extensively researched and done by people who were aware of the risks and possible complications and that it should not be casually attempted.
"Now that this experiment has been started, please wait for us to either heal or go blind before trying it."
