In lower eyelid surgery, the incision is made in an inconspicuous location along the lash line. Excess fat, muscle and skin are trimmed before the incision is closed with fine sutures. Eyelid swelling, mainly caused by excess fat, can be corrected by a transconjunctival blepharoplasty. The incision, in this case, is made inside the lower eyelid, and excess fatty material is removed. When sutures are used to close this incision, they are invisible to the eye and usually dissolve and leave no visible scar. Under normal conditions, the blepharoplasty procedure can take one to two hours.
