I have a lazy eye after Botox. How can I treat this?

It sounds like you're experiencing a form of eyelid drooping or ptosis following your Botox injection, which can occasionally occur when the Botox diffuses or migrates to nearby muscles responsible for eyelid elevation.
In most cases, this type of effect is temporary and generally resolves within 3-4 months as the Botox gradually wears off. However, since you’ve already noticed this issue for around three months, I recommend a few options that may help improve your symptoms:
Eye Drops: Certain eye drops, like apraclonidine, can sometimes help temporarily lift the eyelid by stimulating nearby muscles. Your doctor may prescribe these if appropriate.
Consultation with an Ophthalmologist: Since you’re experiencing prolonged symptoms, it might be helpful to see an ophthalmologist, especially one who specializes in cosmetic or oculoplastic surgery. They can assess any underlying muscle function issues and may offer solutions tailored to your case.
Patience with Recovery: Botox effects gradually fade, so it’s likely that your symptoms will continue to improve as the treatment wears off. However, be sure to keep your provider updated on any changes.
It’s encouraging that your doctor has been monitoring your case, so keep following up with them.
Best wishes for a full recovery.

Thank you for sharing your question. Usually the droopy eyelid is the result of Botox effecting the muscle which raises the eyelid. I trademarked a drop which can be used to correct this problem “Drop N’ Lift). See an oculoplastic surgeon for proper guidance.
Good luck!
