Would I be able to use Uber/Lyft/etc. after lower blepharoplasty or do doctors have an issue with this?

Whether you could take Uber or Lyft after your lower blepharoplasty would be primarily dependent on what type of anesthesia you are having. If the procedure is being done just with local anesthesia, you most likely would be able to take Uber of Lyft. If you are going to have some IV medications, you most likely would not be able to take Uber or Lyft. I would check with your surgeon's office, as they may have different rules. If you are not able to take Uber or Lyft afterwards, your surgeon's office would most likely have information on a transportation service that would be able to take you home.

A main priority of plastic surgery is safety. To answer your question, if you undergo any kind of sedation or general anesthesia, it is not safe to go home alone. What if you got dizzy at home and fell and hit your head. Or what if the Uber driver was unscrupulous. It's just not the standard of care. If you are under local anesthesia only, it's not a problem.

It is important to have a trusted ride home after surgery. This is a time when you could be vulnerable and most doctors are not going to let you go home in a ride share.
