If you have a weak levator (eyelid) muscle that has prevented your eye from completely opening and has impaired your vision, Dr. DeAngelis can raise the eyelid and tighten the upper eyelid muscle. If there is excess skin and/or fat present, a blepharoplasty can be performed in conjunction with this procedure. This surgery can be a cosmetic procedure, which means that it is not covered by most medical insurance. If, however, it can be demonstrated that the drooping eyelid impairs the field of vision, then ptosis surgery can be deemed medically necessary and possibly covered by insurance.
