Study design:

Cohort study 

研究目的:

本研究旨在通过Corvis ST技术,分析并比较不同年龄段的屈光不正患者在接受SMILE手术前后CB的变化情况,探讨年龄因素对CB特性的影响,以及这些变化如何关联手术效果和术后恢复。同时,本研究还将探究CB参数的变化对于预测手术效果、指导术后用药和康复的潜在价值,以期为优化手术方案、提高手术安全性和效果、以及制定个性化的术后管理策略提供科学依据。  

Objectives of Study:

This study aims to utilize the Corvis ST technology to analyze and compare changes in corneal biomechanics (CB) among refractive error patients of different age groups before and after SMILE surgery, investigating the influence of age on CB characteristics and how these changes correlate with surgical outcomes and postoperative recovery. Additionally, the study will explore the potential value of CB parameter changes in predicting surgical efficacy, guiding postoperative medication, and rehabilitation, with the goal of providing a scientific basis for optimizing surgical protocols, enhancing safety and effectiveness, and developing personalized postoperative management strategies.

原始数据存储于加密的电子数据采集系统(EDC),定期备份至云端服务器;纸质文件存放于机构档案室,保存期至少5年。数据修改需经主要研究者批准并记录修改日志

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

The original data is stored in an encrypted electronic data capture (EDC) system and backed up regularly to a cloud server. Paper documents are archived in the institutional records room for a minimum retention period of 5 years. Any data modifications require approval from the principal investigator and must be documented in an amendment log.
