高近视 (HM) 可能会增加患干眼病 (DED) 的风险,在切割镜片提取 (KLEx) 手术后. 低近视患者在KLEx后经历了更好的DED结果.
科学领域:
- 眼科医生 眼科 眼科
- 折射手术是一种折射手术.
- 干眼疾病 干眼疾病
背景情况:
- 干眼病 (DED) 是眼部手术后的一个常见并发症.
- 需要进一步调查的是,近视度对术后DED的影响,其原因是断性透视镜取 (KLEx).
研究的目的:
- 调查近视严重程度与KLEX手术后DED的发生率和严重程度之间的关系.
- 为了比较低近视 (LM) 和高近视 (HM) 组之间的术后DED结果.
主要方法:
- 追溯队列研究,包括LM组的95只眼睛和HM组的76只眼睛接受KLEX.
- 评估的术后结果包括撕裂破裂时间 (TBUT),希尔默测试,眼睛表面染色和DED症状.
- 统计分析采用了独立的t测试和通用线性模型.
主要成果:

One-Degree-of-Freedom System
846
In mechanical engineering, one-degree-of-freedom systems form the basis of a wide range of electrical and mechanical components. Using these models, engineers can predict the behavior of various parts in a larger system, which gives them insight into how different forces interact with each other.
A one-degree-of-freedom system is defined by an independent variable that determines its state and behavior. One example of a one-degree-of-freedom system is a simple harmonic oscillator, such as a...

Degrees of Freedom
7.2K
The degree of freedom for a particular statistical calculation is the number of values that are free to vary. Thus, the minimum number of independent numbers can specify a particular statistic. The degrees of freedom differ greatly depending on known and uncalculated statistical components.
For example, suppose there are three unknown numbers whose mean is 10; although we can freely assign values to the first and second numbers, the value of the last number can not be arbitrarily assigned.

Correlations
35.9K
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

Degree of Unsaturation
10.6K
The degree of unsaturation (U), or index of hydrogen deficiency (IHD), is defined as the difference in the number of pairs of hydrogen atoms between the compound and the acyclic alkane with the same number of carbon atoms. Each double bond or ring costs two hydrogen atoms compared to a saturated analog and results in one degree of unsaturation.
The degree of unsaturation for hydrocarbons is U = (2C + 2 − H) / 2, where C is the number of carbon atoms and H is the number of hydrogen atoms.
The degree of unsaturation for hydrocarbons is U = (2C + 2 − H) / 2, where C is the number of carbon atoms and H is the number of hydrogen atoms.
