|Drooping or sagging eyelids are a normal consequence of changes in the elastic fibres of the skin which becomes less resilient as we grow older. Operations around the eye are either to correct a drooping eyelid (upper) or slack eyelid (lower). A drooping lid may cover half of the eye and is due to paralysis or another reason. A slack eyelid, on the other hand, is redundant skin which causes the lid to hang outwards. Known as dermatochalasis, this condition gives the face a tired and exhausted expression. The aim of surgery is to remove the excess skin and to tighten the lids, giving the face a younger and above all fresher appearance. The elasticity of youthful skin can not be recreated, however.
When dealing with so-called "drooping lids" very good results can be achieved by stretching the upper lid. Other functional limitations such as reduced field of sight and inflammation of the edge of the eyelid can also be improved by lid correction.
The classic problem of the lower lid ("bags under the eyes") is usually a result of an excess of fatty tissue. Eyelid surgery (technically known as blepharoplasty) can remove the unwanted bags. Other areas of the face such as chin and neck can be corrected nowadays by modern techniques of cosmetic surgery, as can skin blemishes and so on.
