Blepharoplasty is surgical modification of the eyelid. Excess tissue such as skin and fat are removed or repositioned, and surrounding muscles and tendons may be reinforced. It can be both a functional and cosmetic surgery.
Blepharoplasty is often done as an elective surgery for cosmetic reasons. Lower eyelid blepharoplasty is almost always done for cosmetic reasons, to improve puffy lower eyelid “bags” and reduce the wrinkling of skin.
Asian blepharoplasty or double eyelid surgery is a special type of blepharoplasty that creates a crease in the upper eyelid. This “supratarsal epicanthic fold” is common in many races but absent in about half of Asians. Surgery can artificially create this crease and make a ‘single-lidded’ patient appear ‘double-lidded’.
Blepharoplasty is sometimes needed for functional reasons. When an advanced amount of upper eyelid skin is present, the skin may protrude over the eyelashes and causes a loss of peripheral vision.
The outer and upper parts of the visual field are most commonly affected and the condition may cause difficulty with activities such as driving or reading. In this circumstance, upper eyelid blepharoplasty is performed to improve peripheral vision.
