【摘要】：目的： 通过分析飞秒制瓣LASIK手术患者术前、术后视疲劳评分及视功能变化的差异，来探索中度近视人群（非老视者）术后视觉疲劳的程度与术前戴镜近视矫正状态的关系。 方法： 选择2012年12月~2013年3月来我院眼视光医学中心行双眼飞秒制瓣LASIK手术的近视患者共36例（72只眼），按术前配戴框架眼镜的近视矫正状态，分为相对足矫组和相对欠矫组，观察视疲劳评分、调节幅度、远/近距水平隐斜、AC/A，，远/近距正/负融像性聚散（Distant/NearPositive/negativeFusionVergence）手术前后数值的变化，分析其与视疲劳评分的相关性。 结果： 1.视觉疲劳症状方面，术前相对足矫组和相对欠矫组评分无差异，术后相对足矫组评分小于相对欠矫组；相对足矫组术前评分小于术后，相对欠矫组术前评分小于术后。2.视功能参数方面。a.手术前后，相对足矫组患者单眼调节幅度均值均大于相对欠矫组；两组术后调节幅度均值均大于术前。b.术前足矫组与欠矫组的远距水平隐斜均值、近距水平隐斜均值无统计学差异(p0.05)；术后足矫组与欠矫组的远距水平隐斜均值差异无统计学意义(p0.05)；但术后足矫组近距水平隐斜均值大于欠矫组；足矫组和欠矫组手术前后远距水平隐斜均值差异均无统计学意义(p0.05)；足矫组术前近距水平隐斜均值与术后无统计学差异(p0.05)，欠矫组术前近距水平隐斜均值大于术后。c.术前足矫组AC/A均值小于欠矫组,术后足矫组AC/A均值仍小于欠矫组；手术前后足、欠矫两组术后均值均小于术前。d.术前足矫组和欠矫组远近融像性聚散均值无差异(p0.05)，术后足矫组和欠矫组远近融像性聚散均值也无差异(p0.05)；但不管是足矫组还是欠矫组，它们手术后的远距正融像性聚散均值、近距正融像性聚散均值均小于术前，远距负融像性聚散、近距负融像性聚散均值改变均无统计学意义(p0.05)；3.LASIK术后调节幅度越小、近距外隐斜越大、AC/A越大、近距融像性储备越小，术后视疲劳症状越明显。 结论： 1、术前相对欠矫状态人群，行飞秒LASIK术前及术后的视疲劳症状均较相对足矫状态人群重。 2、LASIK手术后视觉疲劳症状程度，除去年龄、屈光度外，与术前调节幅度、近距离正融像储备成负相关关系，与术前近距离外隐性斜视程度、调节与集合幅度成正相关关系。
[Abstract]:Objective: to analyze the difference of visual fatigue score and visual function in patients with femtosecond flap LASIK before and after operation. To explore the relationship between postoperative visual fatigue and preoperative correction of myopia in moderate myopia (non-presbyopia). Methods: from December 2012 to March 2013, 36 patients (72 eyes) with binocular femtosecond flap LASIK were selected. The patients were divided into two groups: relative foot correction group and relative undercorrection group. The changes of visual fatigue score, adjustment amplitude, distance / close-range horizontal oblique, and AC/A, distant / close-range positive / negative fusion astigmatism (Distant/NearPositive/negativeFusionVergence) before and after operation were observed. The correlation between visual fatigue score and visual fatigue score was analyzed. Results: 1. In terms of visual fatigue symptoms, there was no difference between the preoperative relative foot correction group and the relative undercorrection group, the preoperative score of the relative foot correction group was lower than that of the relative undercorrection group, the preoperative score of the relative foot correction group was smaller than that of the post-operative group, and the preoperative score of the relative undercorrection group was smaller than that of the post-operative group. 2. Visual functional parameters. A. Before and after operation, the mean value of monocular adjustment amplitude in the relative foot correction group was higher than that in the relative undercorrection group, and the mean value of postoperative adjustment amplitude in the two groups was higher than that in the preoperative group. There was no significant difference between preoperative foot correction group and undercorrection group (p0.05), but there was no significant difference between foot correction group and undercorrection group (p0.05). But there was no significant difference between the foot correction group and the undercorrection group before and after operation (p0.05), but the mean value of the close horizontal oblique in the foot correction group was higher than that in the undercorrection group after the operation, and there was no significant difference between the foot correction group and the undercorrection group before and after the operation. There was no significant difference between preoperative and postoperative close level oblique mean in foot correction group (p0.05), and the mean value of close level covert deviation in undercorrection group was higher than that in postoperation group (p0.05). The mean value of AC/A in the preoperative foot correction group was lower than that in the undercorrection group, and the AC/A value in the postoperative foot correction group was still lower than that in the undercorrection group, and the postoperative mean before and after operation in the foot correction group was lower than that in the preoperative foot correction group. There was no significant difference between preoperative foot correction group and undercorrection group (p0.05), and there was no significant difference between foot correction group and undercorrection group (p0.05). However, in the foot correction group and the undercorrection group, the mean values of the distant positive fusion astigmatism and the close-range positive melt astigmatism were lower than those of the preoperative, and the distant negative fusion astigmatism was lower than that before the operation. There was no significant difference in the mean value of close negative fusion aggregation (p0.05). The smaller the adjustment amplitude, the greater the close-distance oblique, the larger the AC/A, the smaller the accommodation reserve and the more obvious the symptoms of visual fatigue after 3.LASIK. Conclusion: 1. The symptoms of visual fatigue before and after femtosecond LASIK were more serious than those in patients with relative undercorrection. (2) the degree of visual fatigue after LASIK operation, except age and diopter, had a negative correlation with the preoperative adjustment amplitude and the reserve of close-range positive melt image, and had a positive correlation with the degree of recessive strabismus before operation, and the adjustment with the amplitude of set.
