Can Botox Help with Correcting a Lazy Eye?

I would recommend that you seek evaluation by an oculoplastic surgeon who in familar with the technique for Botulinum Toxin (Dysport and Botox) for strabismus

Botox was noted for its cosmetic effects when an ophthalmologist, Dr. Jean Carruthers in Vancouver, Canada, was treating ocular conditions with Botox and her patients noted that some of the wrinkles, at the Crow's feet, were improved. Dr. Carruthers, mentioned this to her husband, Dr. Alastair Carruthers, a dermatologist, and soon they began investigating its uses. See a board-certified oculoplastic surgeon or ophthalmologist for an evaluation.

BOTOX was originally developed as a treatment for Strabismus which is the more technical term for lay eye.  Generally muscle surgery to align the eyes is most commonly used.  There are circumstances when BOTOX is used to temporarily align the eyes such as when the muscle weakness is thought to be short lived.  Please recognize that these types of injections are only done by very specialized ophthalmologists who practice strabismus or neuroophthalmology.  The nurse doing BOTOX at the corner spa is not the person to do or answer questions regarding this treatment.
