When is the best time to operate for strabismus combined with amblyopia or hyperopia? Amblyopia treatment and correction of hyperopia should be carried out first to restore the balance of vision in both eyes, and then, if the vision in both eyes reaches a normal level or if the treatment is not effective, surgery should be performed at a later date depending on the condition. Must amblyopia be completely cured before surgery? Surgery after the amblyopia is cured can promote faster recovery of vision in both eyes after surgery. If the amblyopia treatment is not effective or the patient gives up the treatment, the treatment plan can also be changed according to the condition and surgery can be performed at a later date. Sometimes there are benefits to amblyopia training and vision improvement after strabismus correction surgery, such as amblyopia caused by some restrictive strabismus, and surgery followed by amblyopia training may be recommended.
