In upper eyelid surgery, the surgeon first marks the individual lines and creases of the lids in order to keep the scars as invisible as possible along these natural folds. The incision is made, and excess fat, muscle, and loose skin are removed. Fine sutures are used to close the incisions, thereby minimizing the visibility of any scar.

In lower eyelid surgery, the surgeon makes the incision in an inconspicuous site along the lashline and smile creases of the lower lid. Excess fat, muscle, and skin are then trimmed away before the incision is closed with fine sutures. Eyelid puffiness caused primarily by excess fat may 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 kind of incision, they are invisible to the eye. They are also self-dissolving and leave no visible scar. Under normal conditions, blepharoplasty can take from one to two hours.
