研究目的: |
本研究旨在评估SMILE、FS-LASIK和TPRK切削深度预测的准确性,并探讨影响其准确性的因素。同时,我们还比较术前和术后的角膜中央上皮层厚度,以揭示术后角膜上皮重塑的影响。 |
||||||||||||||||||||||
|
Objectives of Study: |
This study aims to evaluate the accuracy of ablation depth prediction in SMILE, FS-LASIK, and TPRK procedures, and to investigate the factors influencing its predictability. In addition, we compare the preoperative and postoperative central corneal epithelial thickness to reveal the effects of epithelial remodeling after 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: |
收集纳入受试者的术前、术后3月、6月、12月的检查数据。裸眼视力、最佳矫正远视力、主觉验光等数据从受试者的病历资料中录入。Pentacam地形图数据、SD- OCT角膜厚度数据从检查机器导出。数据存储至加密网盘,每月将数据备份至移动硬盘,以上均仅课题组内人员可访问。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Preoperative and postoperative data at 3, 6, and 12 months were collected for all included subjects. Data such as uncorrected distance visual acuity (UDVA), best-corrected distance visual acuity (BCDVA), and manifest refraction were extracted from the patients’ medical records. Pentacam corneal topography and SD-OCT corneal thickness data were exported directly from the diagnostic devices. All data were stored on an encrypted cloud drive, with monthly backups to an external hard drive. Access to the data was restricted to members of the research team only. |
