Botulinum toxin and myectomy help to control blepharospasm but may not cure it.

Botulinum toxin A is a safe, long-term treatment for patients with benign essential blepharospasm, but sustained treatment efficacy may require higher doses in later stages of the disease. [17]

Botulinum toxin injections are sometimes still required following myectomy of the eyelid protractors.
