The Study Of The Changes Of Binocular Function Before And After Corneal Refractive Surgery In Anisometropic Patients

Objective: The purpose of this study was to investigate the changes in the visual function of the anisometropic patients before and after 3 months of corneal refractive surgery.Methods: A total of 20 cases of anisometropia(40 eyes)were selected.Corneal refractive surgery was performed on selected patients.And the patients were examined the naked vision,diopter,near stereopsis,Worth 4point,binocular assembly function,regulation function,and carry out the questionnaire of visual fatigue before and after corneal refractive surgery.All the examination indexes of all patients before and after 3 months after operation were observed and compared.The statistical analysis was carried out with SPSS 21 software,and P < 0.05 was used as the standard of statistical difference.Results:1.In the 3 months after corneal refractive surgery,the diopter was(+1.25~-1.88)D,with an average(-0.16 + 0.87)D.The difference was(0.00~1.00)D,average(0.53±0.35)D.2.Three months after corneal refractive surgery,the near stereopsis and binocular Worth4 point test in anisometropia patients were no statistical significance before and after the operation.3.Three months after corneal refractive surgery in patients with anisometropia,the recovery point in distance convergence/divergence function has statistical significance compared with the preoperative,the residual function parameters are not statistically significant before surgery.4.Three months after corneal refractive surgery,the binocular accommodation flexibility,binocular accommodation amplitude were statisticalsignificance compared with the preoperative meaning.The residual adjustment parameters are not statistically significant before surgery.5.The visual fatigue score of the patients with anisometropia at 3 months after corneal refractive surgery was statistically significant before surgery.Conclusions:1.Corneal refractive surgery for adult patients with anisometropia is not only good for safety,efficacy,predictability and stability,but also helps to improve fusion function,adjustment function and binocular stereoscopic vision.2.Corneal refractive surgery for adults with anisometropia can significantly relieve the symptoms of ocular fatigue.3.In adult anisometropic amblyopia,visual function training after corneal refractive surgery has a positive effect on improving the vision and improving binocular vision function of amblyopia.
