Botox has its effects directly on the muscle into which it is injected. Its effects only last about three months. In strabismus, the goal is to weaken the affected muscle on one side of the eye so that the muscle on the opposite side of the eye can work better.
For the majority of patients the beneficial effects are usually seen three to four days after the injection. The Botox injection is expected to last for six to nine months, but this will vary for each patient. The effect of Botox gradually wears off and most patients will require further injections.
