概括

这项研究比较了白内障手术后的两种多焦点眼内透镜 (SMIOL). 这两种镜头都提供了良好的视力,SBL-2在中距离上表现出色,SBL-3在远距离和近距离视力上表现出色.

科学领域:

眼科医生眼科眼科
生物医学工程生物医学工程
视觉科学科学视觉科学

背景情况:

白内障手术通常涉及眼内透镜 (IOL) 植入以恢复视力.
多焦眼镜的目标是在多个距离上提供清晰的视力,减少对眼镜的依赖.
分段式多聚焦眼内透镜 (SMIOL) 代表了眼内透镜技术的进步.

研究的目的:

为了比较双边细分多聚焦眼内透镜 (SMIOL) 植入后的患者的客观视力质量.
为了评估两个特定的SMIOL模型的视觉性能:SBL-2和SBL-3.

主要方法:

一项追溯前性研究,涉及55名接受双边SMIOL植入的患者的110只眼睛.
根据植入的透镜,患者被分为两组:SBL-2 (62只眼睛) 和SBL-3 (48只眼睛).
在6个月的随访期间,评估了手术后视力敏度 (未纠正和纠正),距离,中间 (66厘米) 和近 (40厘米),以及双眼失焦曲线.

主要成果:

在术后6个月,SBL-2和SBL-3 SMIOL都显示出出色的视觉结果.
与SBL-2组相比,SBL-3组表现出更好的双眼未经校正的距离视敏度 (UCDVA) 和未经校正的近视敏度 (UCNVA).
在66厘米的未经纠正的中间视敏度 (UCIVA) 中,SBL-2组表现更好.

结论:

在白内障手术后,SBL-2和SBL-3 SMIOL都能有效地在不同距离上提供良好的视力.
在SBL-2和SBL-3之间的选择可能取决于所需的视觉结果,SBL-2偏好中间视力,SBL-3偏好远视和近视.

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,...
