Double Eyelid Revision, How High can the Crease be Raised?

I had double eyelid surgery 2 months ago.I prefer how it looks when it was slightly swelling as the crease are higher. now that the swelling has gone down, my double eyelid has become much lower and the edge of the eyelids are going downwards(the shape is a bit triangular) Question: 1) how much can i raise my double eyelid as i already did the incision surgery once? 3)will my lashes upturn? 4)will the scar be very much noticable?
