The orthoptist can also put different prisms in front of the eye in order to deflect the image and make it harder for the oculomotor muscles to work even harder.

The orthoptist can still intervene again in adulthood, in case of reappearance of an old or residual strabismus, for example: in this case, a series of twelve to fifteen orthoptic sessions to stimulate the vision of both eyes and getting them to work in a coordinated fashion is readily prescribed.

Finally, the orthoptist is called upon when there is persistent diplopia (double vision) because it is unbearable on a daily basis. To help the images of the left eye and the right eye to merge when the oculomotor muscles in one of the eyes are unresponsive (in the context of a neurological condition in adults, for example), the An orthoptist can use a striated plastic film, stuck to the spectacle lens and which acts as a prism, in order to deflect the image. Subsequently, this type of correction can be incorporated into the lens.
