What does the operation involve?

The muscles of the eye.

The operation is usually performed under a general anaesthetic but various anesthetic techniques are possible. The operation usually takes about 40 minutes.

Your surgeon will make a small cut on the surface membrane of your eye (conjunctiva). They will separate one or more eye muscles from the surface of your eyeball.

Using small dissolvable stitches, your surgeon will reattach the muscles, making them tighter or looser than they were before, depending on the correction that needs to be made.
