Is It Safe to Get a Blepharoplasty in the Doctor's Office?

In most states office based surgery is regulated if more than mild sedation is given. If your surgery is done with local anesthesia or local plus mild oral sedation it may not be regulated.
Upper blepharoplasty is a low risk and usually low pain procedure so if you are not being given IV sedation it can be safely done in an office setting. If you have a medical history or low pain tolerance you may want to have IV sedation given in which case you should be monitored in an accredited office based or ambulatory surgery center.
The largest accreditation organization for outpatient surgery is the Accreditation Association for Ambulatory Health Care (AAAHC) with over 4000 facilities accredited.
Members of the American Academy of Facial Plastic & Reconstructive Surgery are required by membership standards to perform surgery only in Accredited facilities if more than mild sedation is administered.

Although eyelid surgery, called blepharoplasty, can be done under local anesthesia close monitoring of heart rate and blood pressure are required.
During the surgery it is often necessary to press on the eye which in some people can cause the heart rate to slow - if this occurs action must be taken to speed up the heart rate.
If blood pressure becomes too high during eyelid surgery it can cause bleeding, thus close monitoring of Blood Pressure is necessary.
A hospital or Certified Ambulatory Surgery Center has the personnel and monitoring equipment to assure your safety. Usually an anesthesia person stands by to give you sedation during a local blepharoplasty, which is most helpful and important for your safety.
I would not do a blepharoplasty in an office - the only reason to do so is to save money, a bad idea when it comes to your health and safety.
