In upper eyelid surgery incisions are made in the natural skin folds so that fine scars are less visible. Excess and loose skin can then be removed. In lower eyelid surgery the incision is normally made along the lash line or smile creases of the lower lid (external subcilliary incision) so that excess skin and fat (bags) can then be removed. Occasionally the incision can be made inside the lower eyelid. This is called a (transconjunctival blepharoplasty).
