Double vision 2 weeks after a brow lift is very unusual and something that your surgeon would definitely want to know about. If you haven't already, call your surgeon's office to let him or her know what is going on.If you don't get an answer that makes you comfortable, I would have them refer you to an opthalmologist (finding one that does some cosmetic surgery would be best) sooner than later for an opinion. Good Luck.
Obviously without seeing you there is no way I can make a diagnosis. Blurred vision is not uncommon after blepharoplasty and using ointment. If you just had a brow lift alone it would be very unusual to have double vision after a brow lift alone. I would speak to your plastic surgeon and have him/her refer to to an ophthalmologist who can determine if anything else is going on. Good luck, Dr. Schuster in Boca Raton.
