The eyelid has a complex design, with many intricate layers sandwiched into a structure only a few millimeters thick. Abnormalities of eyelid position and function may develop when even a single layer becomes defective.
The most common causes of problems requiring corrective eyelid surgery include aging, cancer, trauma, birth defects, and complications from previous cosmetic eyelid surgery.
While such conditions pose a serious threat to the health and integrity of the underlying eye, modern corrective eyelid surgery under local anesthesia can usually remedy the problem.
