How Uneven Scars Are Healed and when Undissolvable Stitch Underneath of Skin Can Be Taken out? (photo)

I had low bleph (skin-muscle flap tecnique) by PS to remove malar bags 7 wks ago, but they are still there. My rightt eye scar is 3-4 mms lower than left eye, so it's not healing well. How will it look in 6 mths? What can be done to improve appearance, if still visibe. Also, I feel and see a bump/knot under the skin at the end of the right eye incision. Since the swelling is almost gone,it is more visible. When can the stitch be removed and what would the cost be to remove by someone else?
