I just know when you do good things, it helps other people and makes you feel good... I don't think I'm a goody-goody for one second, but I believe that helping people was the right way to be. And you just gave someone else a hand up, help them up and they'll come back and help you if you need it.

Fred didn't have a favourite colour. He was just pleased that he could see all of the colours in the colour chart. That was his wish for everyone. Fred wanted people to experience the joy of seeing vivid colours - in nature: the greens and browns of the mountains; in their work: the orange, red and black of the back of the retina; and in life.

A smile is just such an amazing thing. And to think that some of those people can now smile because they can see you, that gives me that sort of charge, energy... that's what powers up my batteries. That's the joy that I have and that keeps me going. That's my rocket fuel, I suppose.

No matter how many times I witness the miracle of someone having their sight restored, I'm still overwhelmed with emotion. When the eye patch comes off just 24 hours after surgery and you see that smile light up the room, you are witnessing a life being transformed.
