The use of lasers is very common in dermatology; however, many patients fear it and have various misconceptions about it. A literature search failed to show any studies on this topic.
To explore the various misconceptions of patients about lasers in dermatology.
A self-administered questionnaire containing 21 questions about laser use in dermatology was distributed randomly to patients attending the dermatology clinic at King Khalid University Hospital in Riyadh, Saudi Arabia, from February to April 2009.
The response rate was 79.3%, with 714 of the 900 distributed questionnaires being returned; the individuals sampled included 348 men (48.73%). When asked about the nature of laser, 40% (279 of 698) reported that they did not know. About 36% (251 of 698) knew it was radiation of stimulated light amplification, while 10.2% (71 of 698) reported it to be nuclear radiation. Among study participants, 51.5% (364 of 707) believed that laser was harmful to children, while 51.1% (357 of 699) believed it was unsafe during pregnancy, and 21.4% (146 of 683) thought it could cause skin cancer. Laser was believed to treat most skin diseases by 47.7% (330 of 692) of those interviewed, among whom 24.1% said that they would not accept laser treatment if it was suggested to them by a dermatologist. A stance against laser (16.3%) was most common among men (P<0.001), the illiterate (P=0.006), and those with lower education (P=0.001).
Various misconceptions about laser treatment among patients are prevalent, especially among less educated individuals. Educating the community about laser could solve this problem.
激光在皮肤科中的应用非常普遍；然而，许多患者对此感到恐惧，并存在各种误解。文献检索未能显示出任何关于这一主题的研究。
探讨患者对皮肤科激光的各种误解。
2009 年 2 月至 4 月，我们向沙特阿拉伯利雅得国王哈利德国王大学医院皮肤科就诊的患者随机分发了一份包含 21 个关于皮肤科激光使用问题的自我管理问卷。
回复率为 79.3%，共收回 900 份问卷中的 714 份；抽样个体包括 348 名男性（48.73%）。当被问及激光的性质时，40%（698 人中的 279 人）表示不知道。约 36%（698 人中的 251 人）知道它是受激光放大的辐射，而 10.2%（698 人中的 71 人）报告它是核辐射。在研究参与者中，51.5%（707 人中的 364 人）认为激光对儿童有害，而 51.1%（699 人中的 357 人）认为激光在怀孕期间不安全，21.4%（683 人中的 146 人）认为它会导致皮肤癌。47.7%（692 人中的 330 人）的受访者认为激光可以治疗大多数皮肤疾病，其中 24.1%的人表示，如果皮肤科医生建议他们接受激光治疗，他们不会接受。反对激光的立场（16.3%）在男性中最为常见（P<0.001），在文盲中（P=0.006）和受教育程度较低的人中（P=0.001）最为常见。
患者对激光治疗存在各种误解，尤其是受教育程度较低的人群。对社区进行激光教育可以解决这个问题。
