- 评估两种IOL类型之间的视觉敏度,对比度灵敏度和光学偏差.
- 评估患者报告的视觉舒适度和视觉障碍.
主要方法:
- 一项比较性研究涉及60名患者 (每组30人),两侧植入五焦强度SeeLens IOL或三焦 FineVision POD F IOL.
- 在1个月后的术后评估包括折射,视敏度,失焦曲线,对比度灵敏度和异常度 (哈特曼-沙克和双通).
- 视觉质量 (QoV) 问卷被用于量化视觉舒适度和视觉障碍.
主要成果:
- 在五焦点和三焦点IOL之间观察到类似的距离和近视敏度.

2.6K
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 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,...
