Besides initial swelling and bruising, which should be expected, the most common cosmetic complications stem from insufficient removal of fat, resulting in bulging, unevenness, and irregularity in shape.
There are other, more serious complications associated with this surgery including:
Hematoma
Tearing
Blurred vision or loss of vision
Scarring
Alteration of position of lower eyelid
Additional risks and complications should be discussed with your doctor before surgery.
