There are few elements of the human body which have been left untouched by plastic surgeons. With body modification now more popular than ever, it’s hard to sometimes see where the line should be drawn.

A good place to start, however, is with illegal procedures. Why? Because accepting the work of an unqualified ‘surgeon’ is always going to end in tears – something Instagram model, Nadinne Bruna learned quite literally when she attempted to have the color of her eyes surgically adapted.

The 32-year-old internet star was left with the vision of a 90-year-old woman after the procedure was botched by surgeons in Columbia.

Bruna, who has one million followers on Instagram, flew from her home in Miami, Florida to Columbia for the surgery which is illegal in the US.

She paid an eye-watering $3,000 to have her naturally hazel eyes turned light grey, as part of a discounted deal offered by the surgeon who was impressed with her enormous presence online.

Hopeful that his work on the Argentinian model would be flaunted on Instagram, the surgeon no doubt had dollar signs in his eyes as he imagined people queuing up for the same procedure.
