研究目的:

(1)拟开发一种基于Matlab程序的角膜旋转特征智能识别方法,通过自动测算SMILE术后微切口的旋转度及旋转方向,直接得出眼球旋转参数,避免手工测量带来的临床误差。 (2)在SMILE手术前使用准分子激光仪测量静态眼球旋转度SCC,将术后测量的切口旋转度与SCC进行对比,寻找SMILE术中眼球发生再次旋转的规律,已期为全飞眼球旋转的测量发现新方法。 (3)使用十字校准定位法观察术后切口旋转是否有改善,并使用矢量法评价切口旋转对不同程度近视散光患者的疗效影响。  

Objectives of Study:

(1) A corneal rotation feature intelligent identification method based on matlab program is developed to automatically calculate the rotation degree and rotation direction of the microincision after smile, and directly obtain the eyeball rotation parameters, so as to avoid the clinical error caused by manual measurement;(2) Before smile surgery, excimer laser was used to measure static eye rotation scc, and the measured incision rotation was compared with scc to look for the pattern of eye rotation during size. A new method was found for the measurement of total eye rotation;(3) The cross-calibration positioning method was used to observe whether the incision rotation was improved after surgery, and the vector method was used to evaluate the effect of incision rotation on patients with different degrees of myopic astigmatism.

Outcome:

Incision Rotation

Type:

Primary indicator

测量时间点:

术后1个月

测量方法:

Matlab软件编程计算,核心算法包括以下步骤:加载图像读取并显示包含手术切口的图像,使用ginput函数读取切口数据,然后拟合为直径为7.5毫米的圆。根据圆心坐标和切口中心坐标,就可以及选出旋转角度。

Measure time point of outcome:

1 month post surgery

Measure method:

Matlab Software programming calculation, the core algorithm includes the following steps: load the image read and display the image containing the surgical incision, use the ginput function to read the incision data, and then fit to a 7.5 mm diameter circle. According to the center of the circle and the center of the incision, the rotation angle can be selected.

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:

通过术前检查使用的设备对患者进行常规检查以及数据采集,将结果记录在手术病历中,并录入电子病历系统进行数据管理。眼前段照相结果的图片需要导入matlab软件系统进行数据采集,采集后数据保存在表格中进行统计学分析。

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

Patients were routinely examined and data were collected through the equipment used for the preoperative examination, and the results were recorded in the surgical medical record and entered into the electronic medical record system for data management. The picture of the photographic segment needs to be imported into matlab software system for data collection, and the data should be stored in the table for statistical analysis.
