简介：听力康复训练对人工耳蜗植入患者言语识别能力的提高具有重要的作用。本文就人工耳蜗植入后患者的听力康复训练作一综述。

简介：目的：研究近视患者LASIK术后视疲劳的发生与融合范围的关系，及同视机融合功能训练改善LASIK术后视疲劳的疗效观察。方法：对60例120眼近视患者（．1．50--8．00D）施行LASIK手术，于术前戴全矫眼镜用同视机法测定融合范围，并进行视疲劳的问卷调查。术后将其随机平分为两组：A组进行同视机融合功能训练30d，B组不进行同视机融合功能训练，分别对其术后1wk；1mo行同视机法测定融合范围，并进行视疲劳的问卷调查及统计学分析。结果：A、B组术后融合范围均较术前减小。术后1wk时融合范围两组分别为18．58±8．91和13．45±8．87，二者差异有统计学意义（P〈0．05）。术后1mo时，两组融合范围分别为20．55±7．23和18．12±6．10，二者差异无统计学意义。术后1wk时A组视疲劳评分3．92±1．65，B组评分5．16±2．34，二者差异有统计学意义（P〈0．05）。术后1mo时两组评分分别是1．28±0．96和1．45±0．99分，二者差异无统计学意义。结论：近视眼LASIK术后双眼的融合功能下降是出现视疲劳的一个重要因素。术后早期进行同视机融合功能训练可以有效的改善视疲劳症状。
