Abstract: A method and apparatus for reactivating a paralyzed or non-inervated lateral rectus muscle of the eye. The paralyzed lateral rectus muscle is reactivated by providing a stimulation signal of equal magnitude and frequency of neuronal impulses received by the contralateral medial rectus muscle and detected by an electrode installed therein. The stimulation signal is provided to the paralyzed lateral rectus muscle by way of an electrode installed therein. Control circuitry operates such that the stimulation signal will only be provided to the paralyzed lateral rectus muscle when neuronal impulses are being received by the contralateral medial rectus muscle but not the ipsilateral medial rectus muscle alone and not simultaneously with the ipsilateral medial rectus. The control circuitry will also provide a tonic pulse of predetermined frequency and magnitude to the paralyzed lateral rectus muscle when no neuronal impulses are being sent to the contralateral or ipsilateral medial rectus muscles.
