Depends on location. Different area of the country may have different rates. In my practice the cost is about $1400.00 and is performed under strict local anesthesia since patients cooperation is key to obtain perfect symetry.
Depends . If the lazy eyelid is blocking part of your vision, it can be covered by insurance. The testing to determine this is painless and can be done in most ophthalmologists' offices. If the droop is not blocking your vision, you can expect to pay $1500-2000 for the surgeons fee; there will also be a facility fee and am anesthesia fee if you have the procedure done in a surgery center.
$2500-10,000. This will vary according to technique, technology, implants, anesthesia, time, etc.
