失焦嵌入多段 (DIMS) 眼镜镜头有效地减缓了儿童近视的进展. 这些专用透镜似乎不会增加眼的进展,为年轻近视患者提供了双重好处.
科学领域:
- 眼科医生 眼科 眼科
- 儿科光学测量 儿科光学测量
- 控制近视 控制近视
背景情况:
- 近视是儿童日益严重的公共卫生问题.
- 可以与近视共存,并影响视觉结果.
- 新型眼镜镜片的设计旨在控制近视的进展,同时评估它们对眼的影响.
研究的目的:
- 研究DIMS眼镜镜片对近视儿童眼的作用.
- 为了比较DIMS镜头和单视镜头之间的球形等效,二光子球体,二光子圆柱体,轴长和角膜形的进展,在一年内.
主要方法:
- 一项涉及396名近视儿童的研究,分为DIMS组 (n=192) 和佩戴单视镜片 (n=204) 的对照组.
- 一年后球体等价 (SE),二光子球 (DS),二光子气 (DC),轴长 (AL) 和角膜形 (CA) 的变化分析.
- 统计分析包括矢量图分析,多变量线性回归和混合线性模型来评估群体之间的差异.
主要成果:
- 与对照组相比,DIMS组的每年SE进展明显较慢 (-0.30 ± 0.45D).
- 两组之间观察到二光子气的微小差异,但矢量分析表明对二光子气变化或角膜纹症没有显著的差异效应.
- 多变量和混合线性模型证实,眼镜镜片对白的变化没有显著影响.
结论:
- 失焦嵌入多段 (DIMS) 眼镜镜片有效地减缓了儿童近视的进展.
- DIMS透镜不会诱导或加剧白的进展,这使得它们成为治疗近视与白同时存在的潜在有益选择.

Multiple Regression
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Multiple Voltage Sources
In series, the positive terminal of one battery is connected to the negative terminal of another battery. Hence, the voltage of each battery is added to give the net voltage, which is increased because each battery boosts the electrons that enter it. The same current flows through each battery because they are connected in series.
Batteries are...
Multiple Comparison Tests
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...
