概括
整形外科 (OK) 穿戴可以改变角膜形状,但小切口镜片提取 (SMILE) 是前OK用户的可行的折射手术选择. 长期的OK镜头佩戴可能会导致角膜变化,但SMILE的结果与对照组相似.
科学领域:
- 眼科医生 眼科 眼科
- 折射手术是一种折射手术.
- 角膜生理学 角膜生理学
背景情况:
- 整形眼科 (OK) 是一个常见的近视控制方法在中国.
- 许多年轻人寻求像SMILE这样的折射手术.
- 对于OK对角膜形态和SMILE结果的长期影响尚不清楚.
研究的目的:
- 在长期停止OK治疗后评估眼部生物识别和角膜变化.
- 在前OK使用者和戴眼镜的对照者之间比较SMILE结果.
主要方法:
- 44个近视眼 (22名前OK用户,22名对照) 的回顾性比较研究.
- 在SMILE前后测量角质地形,心态测量和异常.
- 阿尔宾斯向量分析用于形结局.
主要成果:
- 停止使用OK导致角膜形,偏差和后角膜凸的增加.
- 在OK开始时年轻的年龄与较大的后部度相关.
- 在手术后,SMILE结果 (视觉敏度,角膜形状,偏差,正) 在两组之间是可比的.
结论:
- 微笑是一个合适的折射手术选择,适用于具有OK磨损史的个人.

Limits with Oscillating Discontinuities
492
An oscillating discontinuity is a type of discontinuity in which a function’s values fluctuate infinitely often as the input approaches a particular point. Unlike jump discontinuities, where the function suddenly shifts between two values, or infinite discontinuities, where the function diverges without bound, an oscillating discontinuity arises from rapid back-and-forth variation. Because the function never stabilizes toward a single value, no finite limit exists at that point.One of the...

Improper Integrals: Discontinuous Integrands
59
Evaluating Areas Under Curves with DiscontinuitiesA definite integral is considered improper when the integrand is discontinuous at one of the limits of integration. This occurs when the function is undefined or becomes infinite at an endpoint, making the corresponding region under the curve unbounded. Such behavior is commonly associated with vertical asymptotes at the boundary of the interval. To properly define and evaluate these integrals, a limiting process is used to determine whether a...

Predicting Reaction Outcomes
11.0K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Outcomes of Glycolysis
107.8K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Long-term Depression
33.4K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Guidelines for Writing Outcome
4.1K
When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
