7 hours since having Restylane injected in tear trough area and left eye has slight blurriness, I can feel product under my eye.

It is not unusual to feel the filler after injection; however, blurred vision is not a usual side effect so check with your doctor to see if there is something that requires attention and be sure you are seeing a board certified dermatologist or plastic surgeon

Thank you for your question. While it is true that the anesthetic can cause some temporary abnormalities, blurred vision isn't one of them.  7 hours is a long time and the anesthetic usually wears off in 1-2 hours. I would immediately contact your injector and express your concerns.  Tear-trough injections should ONLY be done by a skilled and experienced Board Certified Injector.  Good luck and I hope all is well.Best, Ariel Ostad MD PC
