Photo:She Became Blind After Surgery To Change Her Eye Color

Shenise Farrell is a student from London, who was left temporarily blind after surgery to change the colour of her eyes. She traveled to Panama, in Central America, for the procedure. Her goal was to change her eye colour from dark brown to light brown, an operation that cost her £8,000. All these to the amazement of her family.
             

       
 On arrival at the clinic, plans changed and she got blue implants instead, because the light brown implants were out of stock. During the procedure she screamed but the surgeon told her not to scream as it 'could cause things to go wrong'.
But at the end of the 20 minute procedure, she realised she couldn’t see properly. It was as though she was looking underwater,but the surgeon told her not to worry insisting that for some patients it took up to 2 weeks for vision to return to normal. But by the time she returned to London her sight had deteriorated badly.

She had to go to a hospital in London and the doctors eventually, it was decided that the implants had to be removed. Ms Farrell risked permanent blindness to go under the knife again. This time, surgeons made an incision in her corneas to allow them to remove the implants.
 It took two to three months for her sight to return to normal.
