To determine the prevalence, reasons of use, reported hygienic practices, and complications related to CLs' usage, and to assess awareness of medical students about CLs' hygienic behaviours, King Abdulaziz University (KAU), Jeddah, Saudi Arabia.
A cross-sectional design was done. A multi-stage stratified random sampling was utilized to select 536 medical students. A validated, self-administered, anonymous questionnaire was used. Both descriptive and inferential statistics were applied.
The prevalence of current users of CLs was 40.5%. Females reported significantly much higher prevalence of usage compared to males (OR=8.38; 95% CI:5.2-13.3). Second-year students, and those living in university dormitory had the highest prevalence of CLs usage compared to others. The commonest reason for wearing CLs was cosmetic purpose. Improper CLs-hygienic practices were reported; as exceeding the period required for renewal (45.6%), sharing lenses (16.6%), and sleeping (29.9%), swimming (24.6%) or showering (29.0%) with CLs. Only 16.6% of the participants cleaned their lenses daily. At least one CLs' related complications was reported by 30.4% of the users. Acute red eye (19.8%), conjunctivitis (18.9%), and corneal abrasion (8.3%) were the commonest CLs' complications.
A relatively high prevalence of CLs' usage was found. Participants were aware about CLs-hygienic practices. However, unhygienic CLs-related practices and complications were also reported. Provision of educational messages and training on sound CLs' hygienic practices are needed.
确定沙特阿拉伯吉达阿卜杜勒阿齐兹国王大学（KAU）医学生中隐形眼镜（CLs）的使用 prevalence、使用原因、报告的卫生习惯以及与CLs使用相关的并发症，并评估医学生对CLs卫生行为的知晓情况。
采用横断面设计。利用多阶段分层随机抽样选取536名医学生。使用经过验证的、自行填写的匿名问卷。应用描述性和推断性统计方法。
CLs当前使用者的 prevalence为40.5%。女性报告的使用 prevalence显著高于男性（OR = 8.38；95% CI：5.2 - 13.3）。与其他学生相比，二年级学生以及住在大学宿舍的学生CLs使用 prevalence最高。佩戴CLs最常见的原因是出于美容目的。报告了不当的CLs卫生习惯；如超过更换所需时间（45.6%）、共用镜片（16.6%）以及戴着CLs睡觉（29.9%）、游泳（24.6%）或淋浴（29.0%）。只有16.6%的参与者每天清洁镜片。30.4%的使用者报告至少有一种与CLs相关的并发症。急性红眼（19.8%）、结膜炎（18.9%）和角膜擦伤（8.3%）是最常见的CLs并发症。
发现CLs的使用 prevalence相对较高。参与者知晓CLs卫生习惯。然而，也报告了与CLs相关的不卫生习惯和并发症。需要提供关于正确CLs卫生习惯的教育信息和培训。
