为了评估在光学 (明亮) 和中光学 (暗淡) 照明条件下对比度的灵敏度.
为了评估在植入不同IOLs的患者中光环感知.

主要方法:

一项涉及61名接受Tecnis® EyhanceTM,PhysiOL® IsoPure 123TM或AcrySof® IQ VivityTM眼内透镜的患者的研究.
视觉敏度和对比度的敏感性在光学和中光学照明条件下进行测量.
在第二只眼睛的IOL植入后一个月,在中距离条件下评估了光环感知.

主要成果:

在远距离和中距离的光学条件下,AcrySof® IQ VivityTM IOL显示出明显优于PhysiOL® IsoPure 123TM的性能.
在光学条件下,VivityTM在中间距离上也表现优于Tecnis® EyhanceTM.
在中距离条件下,VivityTM在多个空间频率中表现出卓越的对比灵敏度,并且与PhysiOL® IsoPure 123TM相比,呈现出较少的光环.

结论:

所有三个评估的眼内透镜模型都在白内障手术后的患者中提供了良好的对比度灵敏度.
与其他研究IOL相比,AcrySof® IQ VivityTM IOL表现出卓越的视觉性能,包括更好的对比度灵敏度和减少光环感知.
这些发现表明,VivityTM可能为接受白内障手术的患者提供更好的视觉质量.

Photoreceptors and Visual Pathways

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

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...
