背景情况:
- 面膜眼内透镜 (IOL) 正成为纠正长视的新选择.
- 不同的光学IOL模型的光学性能缺乏直接比较的研究.
研究的目的:
- 为了评估和比较两个不同的光学IOL的光学质量:一个衍射IPCL与+2.5D增加功率和一个折射Artiplus镜头.
- 在不同距离的视觉任务相关的各种条件下评估它们的性能.
主要方法:
- 使用OptiSpheric IOL PRO2系统进行了两种 phakic IOL模型 (IPCL和Artiplus) 的实验室测试.
- 在球形和染色异常条件下的评估,采用3mm和4.5mm光圈,模拟近距离,中距离和远距离的视觉距离.
- 调制转移函数 (MTF) 的分析和1951年美国空军分辨率目标图像的比较.
主要成果:
- 在IPCL和Artiplus镜头之间在3mm瞳孔尺寸的距离之间观察到MTF的微小差异.
- 模拟的视力敏度没有显示距离差异,但在中距离和近距离偏好了Artiplus.
- 两种镜头的光学质量都降低了,光圈更大;Artiplus显示了更平的失焦曲线.
结论:
- 折射性Artiplus和衍射性IPCL (+2.5D添加) phakic IOL均为长视障碍纠正提供了良好的光学质量.
- 在一系列距离上,Artiplus表现更加稳定,而IPCL在预期的焦点上表现出色.
- 在瞳孔较大的患者中,潜在的视敏差异可能更为显著,这表明需要进一步的临床研究.

Focusing of Light in the Eye
5.3K
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...

Open Angle Glaucoma: Treatment
958
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Angle Closure Glaucoma: Treatment
1.1K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
