概括

这项研究发现,在迷你单视设置中,先进的单焦和扩展焦点深度内眼镜 (IOL) 之间的双眼视觉敏度没有显著差异. 这两种内视眼镜类型都提供了可比的距离,中间和近视力结果.

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:

白内障手术通常涉及眼内透镜 (IOL) 植入以恢复视力.
先进的单焦和扩展焦点深度 (EDOF) IOLs代表了视觉康复的不同方法.
迷你单视是一种通过故意在一只眼睛中诱导小的折射误差来实现视力范围的策略.

研究的目的:

使用迷你单焦视觉方法,比较先进的单焦IOL (RAO200E) 和非衍射EDOFIOL (DFT015) 之间的视觉性能.
为了评估与这两种IOL类型的视觉结果的个体间差异.

主要方法:

一个单中心的,随机的,受控的,双重覆盖的研究,涉及48名双边年龄相关白内障患者.
患者在两只眼睛中都接受了RAO200E或DFT015内腔镜,目标是迷你单视折射.
视力敏度 (距离,中等,近距离),对比度灵敏度,失焦曲线,度和视力质量在3个月后被评估.

主要成果:

在RAO200E和DFT015IOL之间,对远距离,中距离或近距离视力的双眼距离校正和未校正视力敏度没有发现显著差异.
在单眼中等和未经纠正的近视敏度中发现了显著的差异,有利于DFT015 IOL.
RAO200E组报告了更小的光环大小,而DFT015组显示出更好的距离校正失焦曲线在-1到-2.5二光度.

结论:

先进的单焦 (RAO200E) 和非衍射EDOF (DFT015) IOL在迷你单视设置中提供可比的双眼视觉敏度,用于远距离,中距离和近距离视觉.
虽然双筒眼的结果是相似的,但单眼的表现和特定的视觉现象,如光环和失焦耐受性可能在IOL之间有所不同.

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,...
