Phase Contrast and Differential Interference Contrast Microscopy

9.4K
Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

科学领域:

  • 眼科医生 眼科 眼科
  • 眼镜测量是指眼睛的测量.
  • 视觉科学 视觉科学 视觉科学

背景情况:

  • 空间时光光学相 (STOP) 技术使用眼镜镜片上的特殊薄膜来潜在地减缓近视的进展.
  • 对于患者接受和有效性至关重要的STOP技术的视觉性能以前没有被评估过.

研究的目的:

  • 评估使用空间时光光学相技术的眼镜片的视觉性能.
  • 为了比较四个测试薄膜设计的视觉性能与没有光学元件的控制薄膜.

主要方法:

  • 这是一项随机的,单口罩,双侧佩戴研究,涉及42名年龄在18-40岁的参与者.
  • 收集了关于视力清晰度,满意度和购买意向的主观数据,以及客观视力敏度 (VA) 和对比敏感度的测量.
  • 分析数据使用线性混合模型和奇平方测试,显著程度为5%.

主要成果:

  • 与对照组相比,所有测试电影在主观评级和购买意图方面显示视觉性能降低.
  • 特定的设计 (F-1,F-2) 显示了近距离的双眼高对比VA降低.
  • 在大多数视觉性能测量中,在测试膜本身之间或在对照和无膜条件之间没有发现显著差异.

结论:

  • 测试的空间时光光学相片对视觉表现产生了负面影响,尽管减少与其他近视管理设备相比.
  • 在四个经过测试的片设计中,其中三种在视觉表现上没有显著差异.
  • 需要进一步的研究来平衡潜在的近视控制益处与观察到的视觉性能权衡.
