Strabismus surgery is a procedure performed on the muscles controlling eye movements. The specific type of eye muscle surgery will depend on the type of strabismus.

The surgery may be done under general anaesthesia (i.e. with the patient fully asleep); or under topical anaesthesia (i.e. with eye numbing eye drops) in co-operative patients.

An incision is made on the conjunctiva (i.e. the transparent layer of membrane covering the white part of the eye), then the eye muscles are located under this membrane and repositioned (i.e. either moved or shortened).

Absorbable sutures are used in most cases, these will dissolve and do not require removal. Non-absorbable sutures may also be used in special circumstances. The conjunctiva is then repositioned over the surgical site with absorbable sutures.
