目的：基于医学生视角评估裂隙灯生物显微镜(以下简称“裂隙灯”)训练的必要性，对眼科见习期间的医学生裂隙灯训练达成共识。

方法：在中山大学117名2017级临床医学专业学生中，开展见习前后对照研究。所有医学生在眼科见习期间均接受裂隙灯训练。使用自行设计的问卷调查，评估学生对裂隙灯教学的个人认知、个人需求与建议，并对眼科见习前后学生在这些方面的得分进行比较。此外，通过眼科见习后的学生主观评价来评估裂隙灯训练的效果。每个条目评分采用Likert 5级评分法。采用IBM SPSS 软件(版本 20.0； SPSS Inc.，Chicago，IL，USA)进行统计分析。

结果：共有116名(99.1%)医学生完成了调查。见习前的平均得分为19.99±3.03分，显示学生对裂隙灯用途的认知水平高； 见习后的得分显著增加至22.97±2.37分(P<0.001)。对于个人需求的平均得分，见习后高于见习前(24.62±3.15 vs 23.60±2.36，P=0.009)。此外，86.2%的学生见习后认为裂隙灯实操训练有助于显著改善见习质量。大于四分之三的被调查学生倾向于增加裂隙灯训练时间(见习前后分别为76.7%和77.6%)。

结论：在眼科见习中，医学生更偏好于裂隙灯训练实操； 鉴于对改善见习质量的潜在作用，应在眼科见习中推荐该训练。

METHODS: A controlled before-after clerkship study was performed on 117 students of the class of 2017 enrolled in clinical medicine at Sun Yat-sen University. All medical students underwent slit-lamp training during ophthalmology clerkship. We evaluated the students' cognition, perceived need and recommendations for slit-lamp teaching, using a self-completed questionnaire survey and compared the students' scores in these aspects before and after their ophthalmology clerkships. Additionally, the efficiency of slit-lamp training was evaluated by subjective student assessment after the ophthalmology clerkship. Each item was scored on a five-point Likert Scale. Statistical analysis was performed by IBM SPSS(Version 20.0; SPSS Inc., Chicago, IL, USA).

RESULTS: A total of 116(99.1%)medical students completed the survey. The average score before clerkship was 19.99±3.03, which indicated a high level of cognition regarding slit-lamp utility; However, this score significantly increased to 22.97±2.37 after clerkship(P<0.001). The average score regarding perceived need was also higher for post-clerkship students than for pre-clerkship students(24.62±3.15 vs. 23.60±2.36, P=0.009). Moreover, 86.2% of post-clerkship students reported that hands-on slit-lamp practice could help promote clerkship quality. More than three-quarters of the surveyed students tended to agree that slit-lamp practice time should be increased(76.7% and 77.6% before and after clerkship, respectively).

CONCLUSION: A hands-on approach to slit-lamp training is more favored by medical students in ophthalmology clerkships, and this training should be recommended in ophthalmology clerkships given its potential usefulness for improving clerkship quality.
