||||||||||||||||||||||
|
药物成份或治疗方案详述: |
1.标准超声乳化手术(对照组): 做透明角膜切口(2.2-3.0mm),注入粘弹剂,居中连续环形撕囊(CCC),直径5-5.5mm,晶状体核乳化,皮质抽吸(完全彻底吸除),植入人工晶状体,抽吸粘弹剂。术毕。所有患者不行前囊抛光。 2.蒸馏水滴注留置(试验组):超声乳化步骤同对照组常规操作。抽吸皮质后,压迫角膜切口后唇,排出囊袋内前房的平衡盐溶液,气液交换模式下侧切口插入23G前房维持器,眼内压维持在30mmHg。侧切口注入少量粘弹剂覆盖角膜内皮,密闭角膜切口。连硅胶头套管的专用注射器将0.1ml蒸馏水通过前囊CCC开口缓慢注入囊袋内。在手术显微镜下辅助器械保持眼位固定,观察双凹气液交界面位于囊袋中央,防止蒸馏水漏出囊袋外。三分钟后,利用注射器从眼内移出蒸馏水。BSS冲洗囊袋及前房,植入人工晶状体后完成手术。术中记录手术时间及手术相关的并发症。 |

Description for medicine or protocol of treatment in detail: |
1. Standard phacoemulsification surgery (control group): Make a transparent corneal incision (2.2-3.0mm), inject viscoelastic material, center continuous circular capsulorhexis (CCC), diameter 5-5.5mm, phacoemulsification, cortical aspiration (Completely suck out), implant an intraocular lens, and suck the viscoelastic agent. Surgery completed. Anterior capsule polishing was not performed in all patients. 2. Air-fluid dropping technique (experimental group): The phacoemulsification procedure is the same as the routine operation of the control group. After the cortex is aspirated, the posterior lip of the corneal incision is compressed, and the balanced salt solution in the anterior chamber is discharged from the capsular bag. A 23G anterior chamber maintainer is inserted into the side incision in the air-fluid exchange mode, and the intraocular pressure is maintained at 30mmHg. A small amount of viscoelastic was injected into the side incision to cover the corneal endothelium, and the corneal incision was sealed. A special syringe with a silicone head sleeve slowly injects 0.1ml of distilled water into the capsular bag through the opening of the front capsular CCC. Under the operating microscope, keep the eye position fixed with auxiliary equipment, and observe that the biconcave gas-liquid interface is located in the center of the capsular bag to prevent distilled water from leaking out of the capsular bag. After three minutes, use a syringe to remove distilled water from the eye. BSS flushes the capsular bag and anterior chamber, and completes the operation after implanting an intraocular lens. During the operation, the operation time and complications related to the operation were recorded. |

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: |
(一)分析数据集 (1)意向分析集(ITT集):指合格病例和脱落病例的集合,但不包括剔除病例。 (2)符合方案集(PP集):指符合纳入标准并完成治疗方案的病例集合,即符合试验方案、依从性好、完成CRF规定填写内容的病例。 (3)安全数据集(SS集):至少接受一次治疗,且有安全性指标记录的实际数据。 (二)统计方法 脱落病例比例不宜大于20%,否则应加以分析说明;描述性统计分析:计量资料给出均数、标准差,计数资料给出率等。计量资料分析采用F检验、配对t检验、秩和检验等方法;计数资料分析采用卡方检验、等级资料采用Ridit分析。统计检验均采用双侧检验,检验水准为0.05。统计分析采用SAS软件进行。 (三)统计分析内容 由统计人员撰写统计分析计划书,包括统计方法和分析内容,经主要研究者确认和细化之后不再改动。统计分析报告包括各试验单位及汇总数据的统计分析结果,以多种表格组成。主要分析内容包括: (1)两组病例分布:两组脱落率(总脱落率和因不良事件脱落)比较。 (2)可比性分析:比较人口学资料和其他基础值指标,以衡量两组的可比性。 (3)依从性分析:比较两组病人依从性(按时复诊的情况)。 (4)有效性分析:对主要疗效指标和全局评价指标进行PP和ITT分析;由于本研究是多中心临床试验,分析时应考虑中心效应对疗效指标的影响。 (5)影响疗效因素分析:如年龄、性别,病型,合并用药等因素对疗效的影响。 (6)安全性分析:列表描述两组的不良事件和不良反应(包括各种不良事件的例数)。对不良事件和不良反应发生率、程度、转归、与试验干预的关系等进行统计分析。列表描述两组严重不良事件。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
1. Analyze the data set (1) Intention to analyze set (ITT set): it refers to the set of qualified cases and shedding cases, but does not include excluded cases. (2) Protocol set (PP set): it refers to the set of cases that meet the inclusion criteria and complete the treatment plan, that is, the cases that meet the trial plan, have good compliance and complete the CRF requirements. (3) Safety data set (SS set): the actual data of at least one treatment with safety index records. 2. Statistical methods: the proportion of shedding cases should not be more than 20%, otherwise it should be analyzed; descriptive statistical analysis: the mean and standard deviation of measurement data, the rate of counting data, etc. F-test, paired t-test and rank sum test were used to analyze the measurement data; chi square test was used to analyze the count data and Ridit analysis was used to analyze the rank data. Statistical tests were conducted on both sides, and the test level was 0.05. SAS software was used for statistical analysis. 3. The statistical analysis plan is written by the statisticians, including statistical methods and analysis contents, which will not be changed after being confirmed and refined by the main researchers. The statistical analysis report includes the statistical analysis results of each test unit and summary data, and is composed of various tables. The main analysis contents include: (1) Distribution of cases in two groups: comparison of shedding rate (total shedding rate and shedding due to adverse events) between two groups. (2) Comparability analysis: demographic data and other basic value indicators were compared to measure the comparability of the two groups. (3) Compliance analysis: the compliance of patients in the two groups was compared. (4) Effectiveness analysis: PP and ITT analysis were conducted for the main efficacy indicators and global evaluation indicators; since this study is a multicenter clinical trial, the impact of central effect on efficacy indicators should be considered in the analysis. (5) Analysis of factors influencing the curative effect: such as age, gender, disease type, combined medication and other factors. (6) Safety analysis: list the adverse events and adverse reactions (including the number of adverse events) of the two groups. The incidence, degree, outcome of adverse events and adverse reactions, and the relationship with experimental intervention were statistically analyzed. The two groups of serious adverse events were listed. |
