If it is an adult with strabismus who also has myopia, it should be considered on a case-by-case basis whether myopia surgery is appropriate. For alternating strabismus, myopia surgery might be considered, but generally, it is not recommended. Since strabismus can cause many problems for the eyes, such as inappropriate positioning of the eyeballs during movement, which can easily lead to diplopia or monocular vision, causing issues like double images or binocular vision dysfunction, meaning there is no stereo vision. Patients with strabismus should first undergo strabismus surgery, then consider myopia surgery.
