Before inserting the needle, ask the patient to look downward so that the posterior structures of the eyeball shift upward to avoid injury. During acupuncture, avoid excessive rotation or lifting of the needle, and do not leave the needle in for too long. After withdrawing the needle, gently press and massage the acupuncture point for a moment to prevent bleeding. Moxibustion is not recommended.
