Can I get more Botox after it left me with a lazy eye?

If you had an eyelid droop from Botox you can have additional Botox treatments in the future. The eyelid droop is technique related but can happen in the hands of any injector. If you saw an inexperienced or untrained injector previously seek a second opinion. If you had an eyelid droop after being treated by an experienced physician injector (plastic surgeon or dermatologist) you're likely in good hands and should not experience this issue again. Stephen Weber MD, FACSDenver Facial Plastic Surgeon

Although this is a known complication of Botox injections of the crows feet, it shouldn't happen. It is caused by the Botox leaking into the orbit and affecting the lateral rectus muscle, a muscle that pulls the eye to the side. Too much Botox was injected too close to the eye is the cause. You should be fine getting Botox, but from a different provider.

There are so many options when it comes to getting injectables these days.  Although these are regulated by the FDA and approved for physician use, state laws vary tremendously regarding cosmetic injectables and devices. My experience is that nurse-run clinics with limited physician oversight and generally zero oversight by someone who understands facial anatomy (dermatologic surgeon, plastic surgeon, oculoplastic surgeon).  Botox is incredible safe and tremendously consistent in results, but there are plenty of people who are taught to inject by another nurse or by a sales rep and aren't able to troubleshoot variable facial anatomy.  It sounds like your injection was likely not in the ideal location. I recommend a dermatologist or plastic surgeon for your next injection.  Good luck!
