I am researching for double eyelid surgery and I want a medium crease size but don't know where from 6mm-9mm. I'm thinking 9mm Additionally, I know that as swelling subsides your crease height will shorten. Will it shorten to the requested crease size or will it be shorter than that Is my surgeon measuring from the middle of my eye as the heightest point ? I'm interested in an almond shape with a soft parallel line
