Cohort study 

研究目的:

本研究旨在探究消除异常光学信号(通过近视矫正手术实现)对不同类型近视患者脉络膜微循环的影响。通过比较眼轴长度不同但屈光度数相似的轴性与曲率性近视患者,分离眼轴增长这一特定因素,以验证其与脉络膜血供下降的因果关系,深化对近视矫正手术背后生物学机制的理解。  

Objectives of Study:

This study aims to investigate the impact of eliminating abnormal optical signals (achieved through refractive surgery) on choroidal microcirculation in different types of myopia. By comparing patients with axial myopia and curvature myopia who have similar refractive errors but different axial lengths, this study seeks to isolate the specific factor of axial elongation to verify its causal relationship with reduced choroidal blood supply, thereby deepening the understanding of the biological mechanisms underlying refractive surgery.

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 a. 采集工具与方法: 电子病例报告表: 本研究将设计标准化的电子病例报告表,用于收集所有数据。eCRF将采用唯一受试者识别码,不记录受试者姓名等个人身份信息,以确保隐私。 标准化设备与设置: 所有光学测量(眼轴长度、角膜曲率)将使用指定的光学生物测量仪(如 IOLMaster)完成。 所有脉络膜参数(CT, CVI, CC FD)将使用同一台指定型号的OCT/OCTA设备进行测量。 在整个研究期间,设备的扫描模式、扫描范围、分辨率等参数设置将保持一致。由同一名或经过一致性培训的技师进行操作,以最大限度减少测量误差。 b. 采集时间点: 严格按照研究方案中规定的访视时间点进行数据采集,包括: 基线期: 入组时(术前) 随访期: 术后1周、1个月、6个月 c. 数据类别: 采集的数据将包括: 人口统计学数据: 年龄、性别。 临床检查数据: BCVA、眼压、裂隙灯及眼底检查结果。 屈光参数: 等效球镜度、眼轴长度、角膜曲率。 主要研究指标: 脉络膜厚度、脉络膜血管指数、脉络膜毛细血管血流密度的原始图像及导出数据。 手术与安全性数据: 手术方式、参数、以及所有不良事件记录。 2. 数据管理 a. 数据录入与核对: 双人独立录入: 由两名经过培训的研究人员将eCRF上的数据独立录入到专用的研究数据库中。录入完成后进行比对,任何不一致之处将核对原始记录进行修正。 逻辑核查: 数据库将设置逻辑核查规则,自动识别异常值、超出范围的数据和缺失项,并生成查询清单,由研究人员核实并更正。 b. 数据存储与备份: 保密性与匿名化: 所有研究数据将进行匿名化处理,使用唯一的受试者筛查编号和随机化编号进行标识,确保数据与受试者个人身份信息分离。 安全存储: 电子数据: 存储在机构安全的、受密码保护的服务器上,访问权限仅限于授权的研究团队成员。 原始文件: 包含受试者身份信息的知情同意书等文件将单独上锁保管。 定期备份: 电子数据库将执行定期(如每日/每周)自动备份程序,以防数据丢失。 c. 数据质量控制: 研究期间,将由一名不直接参与数据采集的研究协调员或质控员定期进行数据审核,确保数据的完整性、准确性和符合方案要求。 所有OCT/OCTA原始图像将由一位不知晓分组情况的资深研究员进行复核,以确保图像质量和测量的一致性。 d. 数据保存期限: 根据《药物临床试验质量管理规范》和赫尔辛基宣言的要求,所有研究相关数据和文件将在研究结束后至少保存 5年。

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

1. Data Collection a. Collection Tools and Methods: Electronic Case Report Form (eCRF): A standardized eCRF will be designed for this study to collect all data. The eCRF will use a unique subject identification code and will not record personally identifiable information such as the subject’s name to ensure privacy. Standardized Equipment and Settings: All optical measurements (axial length, corneal curvature) will be performed using a designated optical biometer (e.g., IOLMaster). All choroidal parameters (CT, CVI, CC FD) will be measured using the same designated model of OCT/OCTA device. Throughout the study, device settings such as scan mode, scan range, and resolution will remain consistent. Operations will be performed by the same technician or by technicians who have undergone consistency training to minimize measurement errors. b. Data Collection Time Points: Data collection will strictly adhere to the visit time points specified in the study protocol, including: Baseline: At enrollment (preoperative) Follow-up Period: 1 week, 1 month, and 6 months post-surgery c. Data Categories: The collected data will include: Demographic data: Age, gender. Clinical examination data: BCVA, intraocular pressure, slit-lamp, and fundus examination results. Refractive parameters: Equivalent spherical power, axial length, corneal curvature. Primary Study Endpoints: Raw images and exported data for choroidal thickness, choroidal vascular index, and choroidal capillary blood flow density. Surgical and Safety Data: Surgical technique, parameters, and records of all adverse events. 2. Data Management a. Data Entry and Verification: Dual Independent Entry: Two trained researchers will independently enter data from the eCRF into a dedicated study database. After entry is complete, the data will be compared; any discrepancies will be corrected by verifying the original records. Logical Validation: The database will be configured with logical validation rules to automatically identify outliers, out-of-range data, and missing entries, and generate a query list for researchers to verify and correct. b. Data Storage and Backup: Confidentiality and Anonymization: All study data will be anonymized and identified using unique subject screening and randomization codes to ensure separation from personally identifiable information. Secure Storage: Electronic Data: Stored on the institution’s secure, password-protected servers, with access restricted to authorized members of the research team. Original Documents: Documents containing subject-identifiable information, such as informed consent forms, will be stored separately under lock and key. Regular Backups: The electronic database will undergo regular (e.g., daily/weekly) automatic backup procedures to prevent data loss. c. Data Quality Control: During the study, a research coordinator or quality control officer who is not directly involved in data collection will periodically review the data to ensure its completeness, accuracy, and compliance with protocol requirements. All raw OCT/OCTA images will be reviewed by a senior investigator who is unaware of the study group assignments to ensure image quality and consistency of measurements. d. Data Retention Period: In accordance with the requirements of the Good Clinical Practice (GCP) guidelines and the Declaration of Helsinki, all study-related data and documents will be retained for at least 5 years following the conclusion of the study.
