Would an eye operation fix a lazy eye on an adult?

Define "lazy eye": Some use this for eyes that don't line up while for others use it for a vision loss condition called amblyopia.Poor alignment is just one factor that can cause amblyopia. Eyes can be lined up with special eye muscle surgery at different ages. Surgery might help a kid regain some vision lost in amblyopia while not in an adult where the brain has turned off accepting input from the weaker eye.
