在KLEX中出现隐形眼动及其对视觉质量和折射结果的影响
概括
在骨折镜片提取 (KLEx) 手术期间,隐形的眼睛运动很常见,特别是在左眼. 虽然通常不会影响折射结果,但显著的运动可能会增加角膜三叶变异.
科学领域:
- 眼科医生 眼科 眼科
- 折射手术是一种折射手术.
- 角膜外科手术 角膜外科手术
背景情况:
- 在手术期间的眼动可能会影响手术的结果.
- 角质折射晶片提取 (KLEx) 涉及精确的激光扫描.
- 了解微妙,看不见的运动的影响对于优化KLEX程序至关重要.
研究的目的:
- 为了评估看不见的眼睛运动对视觉质量和折射效果的影响,在KLEX后.
- 在手术期间识别这些运动的发生率,方向和距离.
主要方法:
- 使用ImageJ软件测量了958只眼睛的眼动方向和距离.
- 基于运动类别 (≤0.1毫米,<0.1毫米,0毫米) 的折射和视觉结果 (折射,,UDVA,SR,MTF,HOAs) 的比较.
主要成果:
- 隐形眼动发生在10.96%的眼睛中,左眼 (17.12%) 的发病率高于右眼 (4.80%).
- 运动主要是向上的 (45°-135°).
- 3个月后没有观察到折射,UDVA,SR,MTF或大多数HOA的显著差异;然而,三叶草偏差在运动≥0.1mm时更高.
结论:
- 隐形的眼睛运动是KLEX手术中经常发生的一种情况,通常是指向高级的,在左眼中更为普遍.
- 手术后的折射结果通常不受这些运动的影响.
- 角质三叶异常可能会随着0.1毫米或更大的手术内运动而增加.

01:16Focusing of Light in the Eye
3.3K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
