I also had the same operation almost 5 years ago now and I know exactly what you're going through with the numbness. However, it does get better... when they made the incision below my eye they cut through some of the nerves. For about a year after the op I could not feel any of my right cheek, upper right lip or the right side of my nose! I was also concerned and went back to see my consultant. What he explained was that the surrounding nerves will actually grow inwards (I think it's called migration). I can now feel most of my face again... it's not the same kind of feeling as the other side of my face but I don't have any of that numbness any more. When I go out in the cold, I have 5 red dots appear below my eye and when I get tired the eyelids drop more than my other eye... but still, it's far better than having a sunken eyeball and double vision!
