Blurry eyes. Can tear duct filler cause this?

Yes its important to let your injector know about this immediately  - If there is a serious eye complication they should have a protocol in place with this to minimise any problems, but treatment needs to be done rapidly if required.

I suggest you see an opthalmologist for review given the rate and degree of eyesight deterioration.The tear duct can be effected by filler but this would produce watery eye rather than blurring.

Hello,
It is possible that this could have been caused by the filler given the timeline of events. Might be best to see the injector and have the product dissolved if its causing you too much grief or not getting better. Not everyone is a candidate for tear trough filler, and this becomes more-so the case with age. There might be other options for your needs that may give you a desired result with less complications.
