测量指标:

Outcomes:

指标中文名:

术中角膜清亮维持时间

指标类型:

主要指标

Outcome:

Intraoperative Corneal Clarity Maintenance Time

Type:

Primary indicator

测量时间点:

术毕

测量方法:

记录手术时间、BSS或F6H8涂布次数。术中角膜清亮维持时间=(最后一次涂布时间-首次涂布时间)/(总涂布次数-1)

Measure time point of outcome:

Upon completion of the surgery

Measure method:

Record the time of surgery and the number of BSS or F6H8 applications. Intraoperative corneal clarity maintenance time = (time of last application - time of first application) / (total number of applications - 1).

指标中文名:

泪膜破裂时间

指标类型:

次要指标

Outcome:

Breakup time (BUT)

Type:

Secondary indicator

测量时间点:

术后1d、1w、2w、4w

测量方法:

使用第5代角膜地形图仪测量。受试者端坐,将Placido盘投影至角膜表面,适当瞬目后固定视线于中心红点处直到下一次瞬目,记录持续固视期间泪膜的变化。重复测量3次取平均BUT。

Measure time point of outcome:

Postoperative 1 day, 1 week, 2 weeks, and 4 weeks

Measure method:

BUT was measured using a 5th-generation corneal topographer. The participant was seated with the Placido disk projected onto the corneal surface. After a normal blink, the participant was instructed to fixate on the central red dot until the next blink, during which changes in the tear film were recorded. The measurement was repeated three times to obtain the average BUT.

指标中文名:

角膜染色评分

指标类型:

次要指标

Outcome:

Corneal fluorescein staining (CFS)

Type:

Secondary indicator

测量时间点:

术后1d、1w、2w、4w

测量方法:

将无菌荧光素钠试纸置于下睑结膜边缘,瞬目后于裂隙灯钴蓝光下观察。将角膜分为4个象限,根据染色程度对各象限评分:0分(无染色)、1分(1-30个点状着色)、2分(>30个点状着色但未融合)、3分(片状/丝状/融合染色)。总分范围:0-12分。

Measure time point of outcome:

Postoperative 1 day, 1 week, 2 weeks, and 4 weeks

Measure method:

A sterile fluorescein sodium strip was placed at the edge of the lower palpebral conjunctiva. After several blinks, the cornea was examined under a slit-lamp microscope using cobalt blue light. The cornea was divided into four quadrants, each scored as follows: 0 points (no staining), 1 point (1–30 punctate stains), 2 points (>30 punctate stains without confluence), or 3 points (patchy, filamentary, or confluent staining). The total score ranged from 0 to 12.

指标中文名:

泪液分泌试验

指标类型:

次要指标

Outcome:

Schirmer II test (SIIt)

Type:

Secondary indicator

测量时间点:

术后1d、1w、2w、4w

测量方法:

于暗光安静环境下,结膜囊点用表面麻醉剂后,将Schirmer试纸条置于下睑结膜囊中外1/3处,嘱患者轻闭眼。5分钟后取出,测量浸湿长度。

Measure time point of outcome:

Postoperative 1 day, 1 week, 2 weeks, and 4 weeks

Measure method:

The test was performed under dim light in a quiet environment. After instillation of a topical anesthetic into the conjunctival sac, a Schirmer test strip was placed at the junction of the middle and outer thirds of the lower conjunctival sac. The participant was instructed to close their eyes gently. After 5 minutes, the strip was removed and the wetting length was measured.

指标中文名:

眼表疾病指数

指标类型:

附加指标

Outcome:

Ocular surface disease index (OSDI)

Type:

Additional indicator

测量时间点:

术后1w、2w、4w

测量方法:

采用OSDI量表进行问卷调查,包含12项症状(如视疲劳、异物感等)。每项按发生频率计0-4分。总分=(各项目得分之和 × 100)/(调查题目总数 × 4)。

Measure time point of outcome:

Postoperative 1 week, 2 weeks, and 4 weeks

Measure method:

The OSDI questionnaire, which includes 12 symptom items (e.g., eye strain, foreign body sensation), was administered. Each item was scored from 0 to 4 based on frequency. The total score was calculated as follows: (sum of all item scores × 100) / (total number of questions × 4).

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:

所有数据将使用预先设计的、标准化的病例报告表(CRF) 进行采集。数据采集人员经过专门培训,严格按照CRF的要求填写数据,并定期进行数据审核和质量控制。CRF以电子形式存储在EDC系统中,数据经过加密处理,只有授权人员可以访问。数据录入及管理人员均接受EDC系统的使用培训,并有技术支持团队随时提供帮助。

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

All data will be collected using a pre-designed, standardized Case Report Form (CRF). Data collectors will receive specialized training to ensure accurate and consistent data entry in strict accordance with the CRF specifications. Regular data review and quality control procedures will be implemented. The CRFs will be stored electronically in an Electronic Data Capture (EDC) system. All data will be encrypted, and access will be restricted to authorized personnel only. Data entry and management staff will be trained in the use of the EDC system, and technical support will be available at all times for assistance.
