数据采集 数据从白内障超声乳化的患者中采集,采用主要和次要评价指标进行检测。数据采集过程遵循指标检测的指南。所有数据均以病例报告表记录,以确保准确性和一致性。 数据管理 采集的数据存储在安全的、受密码保护的数据库中,仅限授权人员访问。为确保数据完整性,定期进行数据备份,并通过与原始记录交叉验证解决数据录入错误。数据匿名化处理以保护参与者隐私,符合同济大学附属同济医院的伦理审查委员会要求。数据分析使用SPSS软件进行,所有数据集在分析前均经过完整性和准确性检查。

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

Data Collection Data were collected from patients undergoing cataract phacoemulsification, using primary and secondary outcome measures for assessment. The data collection process adhered to the guidelines for outcome measure assessments. All data were recorded on case report forms to ensure accuracy and consistency. Data Management The collected data were stored in a secure, password-protected database with access restricted to authorized personnel. To ensure data integrity, regular backups were performed, and data entry errors were resolved through cross-checking with original records. The data were anonymized to protect participant privacy and comply with the ethical review requirements of the Tongji Hospital, Tongji University. Data analysis was conducted using SPSS software, with all datasets undergoing integrity and accuracy checks prior to analysis.
