Does Dysport cause double and blurry vision?

Assuming proper injection, immediate side effects may include lightly swollen pinkish bumps and irritation at injection side that subside after a couple hours. In general, if it continues to feel uncomfortable, consult your doctor to get a complete assessment.

It is possible that the Dysport has affected the muscles that move the eye. This will result in double vision because the eyes won't move in tandem. Injecting these muscles was actually the first approved use of Botox for patients with strabismus, or "lazy eye". Unfortunately, this can't be corrected and the Dysport will have to wear out over the next 3-4 months. I understand that this is a very difficult problem you are experiencing and you should seek an Ophthalmology consultation to make sure that this is actually the problem. The treatment might entail an eye patch so your brain only sees one image and therefore eliminate the double vision. This will affect depth perception though. The problem is cause by injecting too close to the eye in the crowsfeet area or with too large a dose/volume.
