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。

·AIM:To analyze the relationship between visual fatigue and range of fusion after laser in situ keratomileusis(LASIK)in myopia patients,and with fusion function training by synoptophore to improve visual fatigue after LASIK surgery.·METHODS:Totally 60 myopia cases 120 eyes,whose diopters were from-1.50D to-8.00D,were determined the fusion range by synoptophore and visual fatigue questionnaire survey was conducted before LASIK.After LASIK patients were divided randomly into two groups:Group A with 30 days fusion function training by synoptophore;group B with out fusion function training,respectively,after 1 week and 1 month the fusion range was determined and visual fatigue questionnaire survey was conducted,statistical analysis was performed.·RESULTS:Group A and group B were with reduced scopes of fusion range postoperatively,which were statistically significant.1 week after operation,the scopes of fusion range in the two groups were 18.58±8.91 and 13.45±8.87,which were statistically significant(P < 0.05),1 month after operation,the scopes of fusion in the two groups were 20.55±7.23 and 18.12±6.10,which weren’t statistically significant.1 week postoperatively,visual fatigue of group A scored 3.92±1.65,group B scored 5.16±2.34 the difference of which was statistically significant(P<0.05),1month postoperatively,the scores were 1.28±0.96 and 1.45±0.99,the difference wasn’t statistically significant.·CONCLUSION:Decreased fusion function after LASIK surgery is an important factor of visual fatigue.Early postoperative functional training of fusion can effectively improve visual fatigue symptoms.·
