Hi The stitches remaining in your eyelid usually stay along the line. That's why it forms double eyelid line by making artificial adhesion between your skin and stitches. Every surgeon has different method of making sutures, regarding location and numbers. So it means I cannot guarantee that I will be able to remove them all by non-incisional revision. It you want your line to be lowered, then the stitches should be removed by incisional surgery. For the second question, I always check amount of protrusion of eyeball, severity of Mongolian fold, ability of opening and etc. But mostly I listen to patient's demands and try to fulfill their needs based on my experience and measurement during consultation. Yes I use an instrument to demonstrate the best lines. Thank you.
