After strabismus surgery, stereopsis can be restored through fusion training, post-surgical de-inhibition training and stereoscopic function training. 1. Fusion training: The specific training method is that the patient wears two colors of red and green lenses and alternately change the use of 50 cm away from the eyes through the incandescent lamp, artificial light alternately flashing method so that the patient in the meantime to see the image of different stimuli. The flashes were performed 5 times per second for 3 minutes. 2. Post-surgical de-inhibition training: This is the training of blinking rapidly with a relaxed body. By setting up a visual acuity chart or viewing a target and constantly shifting the eyes, the patient is guided to focus on the target and increase the degree of focusing of both eyes. 5 minutes per session, 3 times a day. 3. Stereoscopic training: After strabismus surgery, patients can also be trained through the visual training system software for stereoscopic training of visual functions. Specific treatment recovery should be correctly operated under the guidance of the doctor, to avoid the adverse effects of private operation, it is recommended that the patient consult the doctor in time for scientific and reasonable treatment to restore stereoscopic sense.
