Visual function training is necessary after strabismus surgery. Strabismus surgery is indicated for patients with abnormal visual function and abnormal visual development. Strabismus surgery mainly changes the eye position, signs, and the ability to see the world with both eyes. However, strabismus surgery is not the final treatment, and visual acuity exercises are still necessary after surgery. Since people with strabismus do not have perfect stereoscopic vision, visual acuity exercises after strabismus surgery can be an effective way to help the condition recover and help develop stereoscopic vision. Failure to do visual function training after surgery may affect recovery and may even lead to surgical failure. Visual function training needs to be carried out under the supervision of a doctor until both eyes can distinguish stereoscopic distances when looking at things. Visual function training is necessary after strabismus surgery to help develop stereoscopic vision. It is advisable to seek early medical attention for strabismus and follow the doctor’s instructions to choose the appropriate correction method.
