Blepharoplasty is a type of surgery that removes excess skin from the eyelids. With age, eyelids stretch, and the muscles supporting them weaken. As a result, excess skin and fat can gather above and below your eyelids. This can cause sagging eyebrows, droopy upper lids and bags under the eyes.
Besides aging, severely sagging skin around the eyes can reduce side vision (peripheral vision), especially the upper and outer parts of the visual field. Blepharoplasty can reduce or get rid of these vision problems. The surgery can also make eyes look younger and more alert.
