This is absolutely possible. I know a woman who's entire eye was removed when she was a child, and it grew back completely about 30 years later. No one quite understands why (or why it took 30 years), but the human body is full of surprises.
You got to provide more info than that! Was it suddenly regrown? Or grew in spurts? Slow and steady? At what point did they decide it was regrown? How well does it work? Or is this like some joke I would tell my kids how my leg was chopped off as a child but later grew back?
I should track her down again because its been a few years. But from what I recall, it was slow and steady over maybe 6-8 months. When we met last, it wasn't quite 100% done: the eye was mostly there but it looked cloudy and she was keeping gause over it, so I don't think it "worked" all that well yet. But it did move in sync with the other eye.
