Upper eyelid blepharoplasty is a surgical procedure performed on the upper eyelids to enhance their appearance or improve function by removing excess skin, muscle, and sometimes fat that can lead to sagging, puffiness, or a tired look. This surgery addresses concerns such as drooping eyelids that may obstruct vision or simply restore a more youthful and refreshed look. While primarily considered a cosmetic treatment, upper eyelid blepharoplasty (03 9008 7239) can also have practical benefits, especially for individuals whose sagging lids impair their field of vision. During the procedure, the surgeon marks the upper eyelid to determine the amount of skin to be removed, then makes an incision along the natural crease of the eyelid. Through this incision, excess skin and any protruding fat are carefully excised. In some cases, treatment of underlying muscles or the advancement of the levator muscle may be necessary to address co-existing eyelid drooping, known as ptosis. The incision is closed with fine sutures, leaving a scar hidden in the natural eyelid fold. Recovery typically takes about one to two weeks, during which swelling and bruising resolve, and patients can enjoy a rejuvenated eyelid contour with improved appearance and, if needed, better vision.
