【摘要】 【目的】研究高度近视患者LASIK术后远期视觉相关生活质量。【方法】应用视觉相关生活质量调查问卷对80例高度近视LASIK术后患者及80例术前高度近视患者进行调查,同时对术后患者进行视力、屈光度及近对比敏感度检查,评估术后远期视觉相关生活质量及了解术后常见视觉障碍,评分越高,视觉障碍越严重。【结果】LASIK术后患者生活质量得分为(8.6±8.2)分,低于术前对照组得分(16.2±8.9)分(P<0.05)。视觉障碍阳性率发生较高的前6项条目,依次为电脑使用和阅读容易疲劳(28.8%)、近视力感受变差(22.6%)、夜间视物模糊(22.6%)、眼干涩不适(20.1%)、眩光(20%)、夜间驾驶困难(17.5%)。其中电脑使用和阅读引发视疲劳与术后视力、高空间频率(18 cpd)呈负相关(r=-0.257、-0.265);近视力感受变差与术后视力呈负相关(r=-0.306),与术后屈光度存在正相关(r=0.270);夜间视物模糊与术后视力、低空间频率(3 cpd)存在负相关(r=-0.436,-0.226),与术后屈光度存在正相关(r=0.478);眩光与术后视力、各空间频率存在负相关(r=-0.265~-0.408),与术后屈光度存在正相关(r=0.342);夜间驾驶困难与术后视力、高空间频率(18 cpd)呈负相关(r=-0.351、-0.249),与术后屈光度存在正相关(r=0.369)。【结论】LASIK手术能有效改善高度近视患者远期的视觉生活质量。电脑使用和阅读容易疲劳是LASIK术后远期高度近视患者最常见视觉障碍。更多还原

【Abstract】 【Objective】 To measure the vision-related quality of life of high myopia patients after LASIK. 【Methods】 The vision- related quality of life questionnaire was used to take a survey in 80 high myopia postoperative patients and 80 high myopia patients before LASIK to evaluate the vision-related rate of quality of life and get to know common dysopsia. The more score, the more dysopsia. Other measurements including vision, diopter, and contrast sensitivity test. 【Results】 The overall quality of life score of patients was reduced from(16.2 ± 8.9) to(8.6 ± 8.2)(P < 0.05) after LASIK surgery. The higher positive rate of dysopsia in the first 6 items: visual fatigue from computer and reading(28.8%), vague in near vision(22.6%), vague at night(22.6%), dryness(20.1%), glaring at night(20%), driving difficulty at night(17.5%). The scores of visual fatigue from computer and reading were significantly associated with postoperative visual acuity and high spatial frequency(18 cpd)(r =-0.257,-0.265). The scores of vague in near vision was significantly associated with postoperative visual acuity and postoperative diopters(r =-0.306, 0.270). The scores of vague at night was significantly associated with postoperative visual acuity, low spatial frequency(3cpd) and postoperative diopters(r =-0.436,-0.226, 0.478). The scores of glaring at night was significantly associated with postoperative visual acuity, all spatial frequency and postoperative diopters(r =-0.265 to-0.408). The scores of driving difficulty at night was significantly associated with postoperative visual acuity, high spatial frequency(18cpd) and postoperative diopters(r =-0.351,-0.249, 0.369). 【Conclusions】 Significant vision-related quality of life improvements were found in the majority of high myopia patients in the long- term after LASIK. Visual fatigue from computer and reading is the most common dysopsia.更多还原
