Upper eyelid surgery corrects selected features of the upper lid. Where appropriate, excess skin is removed and other tissue structures may be adjusted. Examination distinguishes excess skin from a lowered eyebrow or a problem with the muscle that lifts the eyelid.
The incision follows the natural eyelid crease. How much skin or other tissue can be removed depends on eyelid closure, the eye surface and the anatomy. Making the incision as short as possible is not automatically the defining measure of quality.
Possible risks include dry eyes, asymmetry, bleeding after surgery and difficulty closing the eyes completely. A scar remains, and its appearance changes during healing. Existing eye symptoms and previous procedures are taken into account when planning surgery.
