I used CS5. Haven't gotten around to getting CS6 yet.
I used the lasso tool and drew around the eye, including some feather area. The I used the Refine Edge Radius slider to make a nice selection edge. (Despite the temptation to use the "Feather" slider for the sake of irony, I resisted. The softening of the edge might have made the edge soft.) Then with the selection made I, I clicked on edit>transform>scale and nudged the corners of the scale box out slightly. Presto! Bigger eye.
