There are many problems which can affect the eyelids, including eyelids that are turned out (ectropion), eyelids that are turned in (entropion), and lax skin of the upper lids (dermatochalasis). Most of these conditions can be treated with lid surgery under a local anesthetic.
Blepharoplasty is a commonly performed cosmetic or functional eyelid operation for excess skin in the eyelids knows as dermatochalasis.
