数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

(1)数据采集:从电子病历获取患者的基础数据、验光结果等;从Pentacam角膜地形图仪器的数据库导出角膜局部曲率值。所有受试者的数据使用标准化数据采集表进行记录。 (2)数据存储:电子病历存储于科室云存储;地形图数据存储于PACS影像系统。定期将上述数据存储至课题组硬盘及网盘。 (3)数据录入:受试者数据将在每次随访后24-48小时内录入电子数据库。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

1.Data Collection: Patient baseline data, refraction results, and other relevant information will be extracted from electronic medical records. Corneal curvature values from the Pentacam corneal topography system will be exported from the instrument’s database. All participant data will be recorded using a standardized data collection form. 2.Data Storage: Electronic medical records will be stored in the department’s cloud storage system, while topographic data will be saved in the PACS imaging system. These datasets will be regularly backed up to the research team’s external hard drive and cloud storage. 3.Data Entry: Participant data will be entered into the electronic database within 24–48 hours after each follow-up visit.
