概括

小切口镜片提取 (SMILE) 维持了一个更大的有效光学区域 (EOZ) 长期比Femtosecond激光辅助在位角膜修复 (FS-LASIK) 的近视. 这两种程序都显示了EOZ随着时间的推移而持续减少.

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:

术后视觉质量受到有效光学区域 (EOZ) 的影响.
在小切口镜片提取 (SMILE) 和五秒激光辅助现场角膜切除 (FS-LASIK) 后比较长期EOZ变化对于折射手术结果至关重要.
这项研究侧重于中度和高近视纠正.

研究的目的:

为了比较小切口镜片提取 (SMILE) 和秒激光辅助现场角膜切除 (FS-LASIK) 后有效光学区 (EOZ) 的长期变化.
分析EOZ,编程光学区 (POZ) 和角膜波浪偏差之间的关系.
评估EOZ变化与特定折射参数之间的相关性.

主要方法:

一组42名患者 (72只眼睛) 接受了SMILE (36只眼睛) 或FS-LASIK (36只眼睛).
使用基于Pentacam HR触角曲率差异图的定制软件测量了有效光学区域 (EOZ),在手术后的3年和7年.
分析了角质波线偏差和EOZ变化与相关参数之间的相关性.

主要成果:

在3年后,EOZ在SMILE (5.13±0.27毫米) 后比FS-LASIK (4.70±0.24毫米) (P<0.001) 后更大.
在7年后,EOZ在两组都下降了 (SMILE:5.03 ± 0.28毫米;FS-LASIK:4.63 ± 0.23毫米) (P < 0.001).
微笑显示了较少的诱导球形偏差,与EOZ/POZ负相关,而FS-LASIK与气校正正相关.

结论:

小切口镜片提取 (SMILE) 导致更大的有效光学区域 (EOZ) 与Femtosecond激光辅助现场角膜修复 (FS-LASIK) 相比,长期用于近视纠正.
在7年的随访期间,SMILE和FS-LASIK的EOZ持续下降.
了解长期EOZ动态对于优化折射手术视觉结果至关重要.

Focusing of Light in the Eye

Focusing of Light in the Eye

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...

Confocal Fluorescence Microscopy

Confocal Fluorescence Microscopy

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...
