Blepharoplasty tightens the eyelid’s muscles and tissue and removes excess fat and skin. This procedure eliminates the dropping 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.
