Blepharoplasty (eyelid surgery) is a plastic surgery procedure for correcting sagging or drooping eyelids. The eyelid, because its skin is much thinner than that in other parts of the face, is often one of the first facial areas to exhibit signs of aging. Eyelids that sag or droop can affect peripheral vision, making daily activities such as driving more difficult. Blepharoplasty may become necessary when various factors, which include aging, sun damage, smoking and obesity, cause the muscles and tissue that support the eyelids to weaken.
Reasons for Blepharoplasty
Blepharoplasty tightens the eyelid‘s muscles and tissue, and removes excess fat and skin. Blepharoplasty eliminates the drooping of skin into the visual field, greatly improving peripheral vision. It is also performed for strictly cosmetic reasons.
If the eyelids begin sagging into the field of vision, a functional blepharoplasty may be required. The procedure may be covered by medical insurance if it is deemed medically necessary. A determination of how much vision is affected is done by checking the peripheral visual field with an instrument called the Humphrey Visual Field (HVF) Analyzer.
Blepharoplasty can be performed on either the upper or lower eyelid, or on both, for cosmetic purposes. For a lower eyelid that needs fat rather than skin removed, a transconjunctival blepharoplasty is performed. During transconjunctival blepharoplasty, an incision is made inside the lower eyelid, so there are no visible scars, and the fat is removed. This procedure has no effect on vision, but results in a person‘s looking younger and more refreshed.
It is important for a patient to have realistic expectations before undergoing cosmetic blepharoplasty. Although the procedure can enhance appearance and improve self-confidence, it does not radically alter the face.
Candidates for Blepharoplasty
The best candidates for blepharoplasty are those who are in good overall health, do not smoke, do not have any serious eye conditions, and have healthy facial tissue and muscle.
People with eye disease, including glaucoma or retinal detachment, thyroid disorders, diabetes, cardiovascular disease or high blood pressure are not good candidates for blepharoplasty.
The Blepharoplasty Procedure
Blepharoplasty is typically performed as an outpatient procedure requiring local anesthesia and sedation. General anesthesia may be used for anxious patients. Patients can choose to have this procedure on their upper or lower eyelids, or both. The procedure can take anywhere from 45 minutes to 2 hours, depending on whether both the upper and lower eyelids are operated on.
If the upper eyelid is being operated on, an incision is typically made along its natural crease. Once the incision is made, fat deposits are repositioned or removed, muscles and tissue are tightened, and excess skin is removed. For the lower eyelid, an incision is usually made just below the lash line so that excess skin can be removed.
After the procedure, the incisions are closed with sutures, tissue glue or surgical tape, and usually loosely covered with gauze so the area can heal.
