<unk>  can be both a functional or cosmetic surgical procedure intended to reshape the upper eyelid or lower eyelid by the removal and/or repositioning of excess tissue as well as by reinforcement of surrounding muscles and tendons. When an advanced amount of upper eyelid skin is present, the skin may hang over the eyelashes and cause 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<unk>  is performed to improve peripheral vision. Patients with a less severe amount of excess skin may have a similar procedure performed for cosmetic reasons. Lower eyelid<unk>  is almost always done for cosmetic reasons, to improve puffy lower eyelid "bags" and reduce the wrinkling of skin.<unk>  is performed through external incisions made along the natural skin lines of the eyelids, such as the creases of the upper lids and below the  lashes of the lower lids, or from the inside surface of the lower eyelid. Initial swelling and bruising take one to two weeks to resolve but at least several months are needed until the final result becomes stable. Depending upon the scope of the procedure, the operation takes one to three hours to complete.
The anatomy of the upper/lower eyelids, patients' skin quality,  patients' age, and the adjacent bony and soft tissue all affect the cosmetic and functional outcomes after<unk> . Factors which are known to cause complications after surgery include failure to recognize factors such as
preexisting dry eyes - which may become exacerbated by disrupting the natural tear film
laxity (loosness) of the lower lid margin (edge) - which predisposes to lower lid malposition
prominence of the eye in relation to the malar (cheek) complex - which predisposes to lower lid malposition
The American Society for Aesthetic Plastic Surgeryestimates the average physician/surgeon fee for<unk>  for 2006 to be around $2,882. These fees are for the physician/surgeon fees only and do not include fees for the surgical facility, anesthesia, medical tests, prescriptions, surgical garments or any other miscellaneous costs related to the surgery. Physicians most qualified to perform<unk> es are plastic surgeons, ophthalmologists, oral and maxillofacial surgeons, and otolaryngologists.
The manner in which<unk>  surgery can alter a person's appearance is best appreciated by comparing before and after photos of surgical patients. Photos are available on a number of surgeon websites including: Dr. Frank Meronk based in Southern California , Dr. Paul S. Nassif based in Beverly Hills, California and Dr. Mitesh Kapadia based in Boston, Massachusetts.
An upper<unk>  in someone who is Asian is termed Asian<unk>  or double eyelid surgery. It is the most popular form of cosmetic surgery among those of east and southeast Asian background. Due to anatomic differences between the asian and occidental eyelid, about half of this population are born without a supratarsal eyelid crease and are called single-lidded. Surgery can be used to artificially create a crease above the eye.
Transconjunctival<unk>  involves removing lower eyelid fat through an incision on the back of the eyelid, eliminating the need for an external incision. Because there is no external incision, excess skin can not be removed during the surgery, but skin resurfacing with a chemical peel or carbon dioxide laser may be performed simultaneously.   This allows for a faster recovery process.
