To identify factors that motivate patients to seek laser in situ keratomileusis (LASIK) treatment for myopia and establish subjective levels of functional improvement and satisfaction across a range of indices after LASIK surgery.

In this questionnaire-based, cross-sectional study, an anonymous 34-item questionnaire was forwarded to 50 consecutive patients in a prospective study who had had LASIK for high myopia by a single surgeon at a single center. The questionnaire used visual analog scales, anchored at each end by an adjectival descriptor. The mean preoperative myopia was -10.7 diopters +/- 4.4 (SD). Seventy-six percent of eyes (83% of patients) achieved post-LASIK uncorrected visual acuity (UCVA) of 6/12 or better; 1 eye lost 2 lines of corrected Snellen visual acuity.
A 98% reply rate was achieved. The most common motivating factor for pursuing LASIK was to improve UCVA (88%); only 21% rated improved cosmesis as an important motive. Most patients (81% to 100%) reported functional improvement across the spectrum of visual tasks assessed, although 8.8% reported difficulty with nighttime driving. Ninety-six percent felt their UCVA was as good as anticipated, 97.9% were satisfied with the speed of visual improvement, 93.8% achieved the goals for which they had surgery, 97.9% reported an improved quality of life, and 97.9% were satisfied with the overall outcome of LASIK.
Using an anonymous, wide-ranging questionnaire, high levels of functional improvement and satisfaction with the speed of visual recovery and outcome were reported by patients after LASIK for high myopia. Nighttime driving symptoms of variable severity were, however, noted by 8.8% of patients, despite high levels of satisfaction with other aspects of visual function.
确定促使患者寻求准分子原位角膜磨镶术（LASIK）治疗近视的因素，并确定LASIK手术后一系列指标的功能改善主观水平和满意度。

在这项基于问卷的横断面研究中，一份包含34个项目的匿名问卷被分发给在一个中心由一位外科医生为高度近视患者实施LASIK手术的前瞻性研究中的50例连续患者。问卷使用视觉模拟量表，两端由形容词描述词锚定。术前平均近视度数为-10.7屈光度±4.4（标准差）。76%的眼（83%的患者）LASIK术后裸眼视力（UCVA）达到6/12或更好；1只眼矫正后Snellen视力下降了2行。
问卷回复率为98%。寻求LASIK手术最常见的动机是改善UCVA（88%）；只有21%的患者将改善美观视为重要动机。大多数患者（81%至100%）报告在所评估的各种视觉任务中功能有所改善，尽管8.8%的患者报告夜间驾驶有困难。96%的患者认为其UCVA与预期一样好，97.9%的患者对视力改善速度感到满意，93.8%的患者实现了手术目标，97.9%的患者报告生活质量有所改善，97.9%的患者对LASIK手术的总体结果感到满意。
通过一份匿名的、涵盖范围广泛的问卷，高度近视患者在接受LASIK手术后报告了高水平的功能改善以及对视力恢复速度和手术结果的满意度。然而，尽管患者对视觉功能的其他方面满意度较高，但仍有8.8%的患者出现了不同严重程度的夜间驾驶症状。
