Objective To analyze the application effect of an automatic device in eyeball movement training for orbital blowout fracture patients after surgery. Methods Totally 100 orbital blowout fracture patients with diplopia and eye movement disorder after surgery were randomized into a control group and an observation group, with 50 patients in each group. The control group trained eyeball using routine suspensory device, while the observation group trained eyeball using a self-designed automatic eyeball training device.The degree of diplopia and eye movement disorder of the two groups were compared at 3 months after the training. Results After the intervention, the degree of diplopia and eye movement disorder of the observation group were significant milder than those of the control group （P＜0.01 for both）. Conclusion Application of an automatic device in eyeball movement training for orbital blowout fracture patients after surgery achieves accurate, standardized and effective eyeball movement training, which is conducive to increasing patients′ recovery of eyeball movement and improving their visual function.
