  • 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。
