概括

与Tecnis Eyhance和ISOPure等增强型单焦眼镜相比,AcrySof IQ Vivity眼内透镜 (IOL) 提供了更好的中间和近视力. 所有测试的IOL都保持了对比度的敏感性,在照明条件之间没有显著差异.

科学领域:

眼科医生眼科眼科
生物医学工程生物医学工程
光学是什么?光学是什么?光学是什么?

背景情况:

增强的单焦和扩展焦点深度 (EDoF) 眼内透镜 (IOL) 旨在改善中间视力和对比度敏感性.
对于这些IOL在光学和中光学条件下存在的比较数据有限.

研究的目的:

为了前性地比较两个增强的单焦IOL (Tecnis Eyhance,ISOPure) 和一个非衍射EDoFIOL (AcrySof IQ Vivity) 的视觉性能.

主要方法:

60名患者接受了双边白内障手术,使用了三种IOL类型之一 (n=20个组).
视力敏度 (距离,中等,近距离) 在手术后一个月的光视和中视条件下被测量.
评估了光学失焦曲线和对比度灵敏度.

主要成果:

在光学条件下,AcrySof IQ Vivity表现出优异的未经校正的距离,距离校正的中间和距离校正的近视敏度.
在中距离条件下,Vivity还显示出更好的中间和近视敏度,而距离敏度在不同组之间是可比的.
在两种照明条件下,所有IOL的对比度都相似.

结论:

非衍射EDoF AcrySof IQ Vivity IOL提供了更广泛的功能焦点深度,而不会影响对比度的灵敏度.
泰克尼斯 Eyhance 和 ISOPure IOL 提供了可比性能,具有良好的远距离视觉和适度的焦点深度延伸.
这三种IOL都保持了与标准单焦IOL可比的对比度灵敏度,没有临床上显著的对比度损害.

关键词:

增强一个焦点的单焦点.扩大了焦点深度的扩展.眼内透镜是眼内透镜的一个组成部分.在 mesopic 的视觉表现中.

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...
