概括

撕膜的度并不总是影响透测量或纹测量在设备上的可重复性. IOLMaster 700和Pentacam AXL显示出可靠的结果,而Galilei G6的整体重复性较低.

科学领域:

眼科医生眼科眼科
视光学测量视光学测量视光学测量
生物医学工程生物医学工程

背景情况:

准确的角质测量和纹测量对于折射手术规划至关重要.
干眼疾病的特点是膜不稳定性和改变的度,可能会影响眼睛测量的可靠性.
了解膜度对测量可重复性的影响,对于优化诊断程序至关重要.

研究的目的:

通过使用三种不同的设备 (IOLMaster 700,Pentacam AXL,Galilei G6) 评估角质计和纹测量的可重复性.
为了确定催膜的度是否会影响这些测量的重复性.
为了比较三种设备在不同膜度条件下的性能.

主要方法:

97名患者的97只眼睛使用IOLMaster 700,Pentacam AXL和Galilei G6.6进行了重复测量.
使用TearLab Osmolarity System测量了膜透度,并将患者分为四个透度组.
使用类内相关系数 (ICC) 和矢量分析来评估测量可重复性和组之间的差异.

主要成果:

在所有器件的所有度组中观察到高重复率 (ICC ≥ 0.957).
纹重复性各不相同,Pentacam AXL和IOLMaster 700在不同组中通常显示高的ICC值.
利略G6表现出较低的重复性对标测量,特别是在较低的标性群体,和矢量分析显示,在任何设备的标性群体之间没有显著差异.

结论:

眼膜的度似乎不是一个显著的混的因素,度和纹测量可重复性与IOLMaster 700和Pentacam AXL.
加利利G6的重复性不太稳定,这表明它对撕裂膜条件的潜在敏感性.
这些发现支持IOLMaster 700和Pentacam AXL在不同眼睛表面状态中的可靠性,同时突出了Galilei G6.的潜在局限性.

关键词:

干眼疾病是干眼的疾病.测角质量测量 (keratometry) 是一种测角质量测量方法.催膜是因为度的度.矢量分析是一种矢量分析.

Ophthalmic Drug Delivery Systems

Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
