研究目的:

主要研究目的: 1. 明确近视散光患者接受SMILE手术后早期(术后3个月内)发生屈光偏差的相关危险因素,重点评价术前屈光参数、角膜形态学参数、生物力学参数及角膜上皮重塑与术后屈光偏差之间的相关性。 2. 评价基于多种机器学习算法构建的Nomogram模型在预测SMILE术后屈光偏差风险中的预测效能,明确其在临床中的可行性与准确性。 次要研究目的: 1. 比较不同机器学习算法(多元线性回归、CART、AdaBoost、XGBoost、MLP)在预测SMILE术后球镜、柱镜及散光轴Nomogram值方面的预测性能差异,筛选最优预测模型。 2. 探索角膜上皮厚度重塑特征与SMILE术后早期屈光回退之间的关系,为术后屈光回退的机制解释提供依据。 3. 构建并初步验证基于人工智能辅助的个体化Nomogram决策模型,为SMILE术前个体化手术设计提供量化参考。  

Objectives of Study:

Primary objectives: 1.To identify risk factors associated with early postoperative refractive deviation (within 3 months) after SMILE in patients with myopic astigmatism, with particular emphasis on the associations between postoperative refractive deviation and preoperative refractive parameters, corneal morphological parameters, corneal biomechanical parameters, and corneal epithelial remodeling. 2.To evaluate the predictive performance of nomogram models developed using multiple machine learning algorithms for estimating the risk of post-SMILE refractive deviation, and to determine the feasibility and accuracy of these models for clinical use. Secondary objectives: 1.To compare the predictive performance of different machine learning methods (multivariable linear regression, CART, AdaBoost, XGBoost, and MLP) for estimating nomogram values for postoperative sphere, cylinder, and astigmatism axis after SMILE, and to identify the optimal prediction model. 2.To investigate the relationship between epithelial thickness remodeling patterns and early refractive regression after SMILE, providing mechanistic evidence for postoperative refractive regression. 3.To develop and preliminarily validate an artificial intelligence–assisted individualized nomogram decision model, providing quantitative guidance for personalized preoperative surgical planning for SMILE.

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:

数据采集与管理:本研究在研究开始前制定统一的研究操作手册与标准操作规程(SOP),对研究对象筛选、知情同意获取、术前检查、手术实施、术后随访、数据录入及数据管理等关键环节进行规范化规定。研究全过程严格按SOP执行,任何偏离均需记录并说明原因。为降低测量误差,研究所用主要设备(飞秒激光手术系统、角膜地形图仪、眼前节光学相干断层扫描及角膜生物力学分析系统)在研究开始前完成校准,并在研究期间按医院规定定期维护与质控;关键测量设备固定型号与参数设置,尽量避免因设备差异引入系统误差。 数据录入与质控:建立统一的电子数据库作为数据汇总与分析基础,采用双人独立录入与交叉核对机制完成数据录入,并设置数据逻辑校验规则,对异常值、缺失值及不合理数据进行自动提示并复核,以提高数据一致性与准确性。所有原始资料、检查报告及手术记录均妥善保存,便于随时核查与追溯。研究负责人定期开展内部监查,重点覆盖入组进展、随访完成情况与数据质量,对发现问题及时反馈并纠正,确保研究按方案执行。研究相关信息仅供伦理委员会及相关机构审阅,未经主要研究者书面同意,不得向与本研究无关的第三方披露。

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

Data collection and management: Before study initiation, a unified study operations manual and standard operating procedures (SOPs) will be developed to standardize key processes, including participant screening, informed consent, preoperative examinations, surgical procedures, postoperative follow-up, data entry, and data management. All study activities will be conducted in accordance with the SOPs, and any protocol deviations will be documented with reasons. To minimize measurement error, major study devices (the femtosecond laser system, corneal topographer, anterior segment optical coherence tomography system, and corneal biomechanical analyzer) will be calibrated before study initiation and undergo periodic maintenance and quality control according to hospital regulations. The models and parameter settings of key measurement devices will be fixed to reduce systematic bias due to device variability.Data entry and quality control: A centralized electronic database will be established as the basis for data aggregation and analysis. Data entry will follow a dual independent entry and cross-verification process. Logical validation rules will be implemented to flag and verify outliers, missing values, and implausible entries, thereby improving data consistency and accuracy. All source documents, examination reports, and surgical records will be securely archived to enable audit and traceability. The principal investigator will conduct regular internal monitoring focused on enrollment progress, follow-up completion, and data quality; identified issues will be communicated and corrected promptly to ensure adherence to the protocol. Study-related information will be available only for review by the Ethics Committee and relevant institutions and will not be disclosed to any third party unrelated to the study without written authorization from the principal investigator.
