METHODS: Totally 120 postoperative children with CS were selected from January 2015 to January 2018 in our hospital. According to the random digital table method, they were divided into the combination group and the prism group, 60 cases in each group, the prism group was given fresnel press-on prisms treatment, the combination group was given mental image network training on the basis, the visual function recovery of the two groups was compared.

RESULTS: After 6mo treatment, binocular visual machine visual function and Titmus near stereopsis visual function in both groups were significantly higher than before, and the binocular visual machine visual function and Titmus near stereopsis visual function in the combination group were significantly higher than those in the single press group, the difference was statistically significant(all P<0.05). The long distance fusion function normal rates in the combination group and the prism group were significantly higher than those before treatment, the long distance fusion function normal rate in the combination group was significantly higher than that in the prism press group, the difference was statistically significant(93.3% vs 70.0%, P<0.05).

CONCLUSION: Fresnel press-on prisms combined with mental image network training can effectively promote the binocular visual function recovery of the postoperative children with CS, which is worth for further clinical promotion.
