概括
延长焦点深度眼内透镜 (IOLs) 与双焦和三焦 IOLs 相比,显示出更好的耐受性. 在EDOF IOL中,即使在诱导性眼症的情况下,也可以保持可接受的近视.
科学领域:
- 眼科医生 眼科 眼科
- 光学是什么?光学是什么?光学是什么?
- 生物医学工程 生物医学工程
背景情况:
- 剩余的白症影响了白内障手术后的视力敏度.
- 多焦眼内镜 (IOL) 的目的是恢复远视和近视.
- 了解不同类型的内腔眼镜对白症的耐受性对于患者的治疗结果至关重要.
研究的目的:
- 为了比较双焦,三焦和扩展焦点深度 (EDOF) IOLs之间对实验诱导的残留白症的耐受性.
- 通过这些IOL,评估的尺寸和轴对远距离和近距离视力敏度 (VAs) 的影响.
主要方法:
- 一项回顾性,比较性研究,涉及70只眼睛使用双焦,三焦或EDOF IOLs.
- 使用圆柱状透镜进行实验诱导的光 (0.50至2.00二光透) 应用.
- 距离和近距离的VA是在90°和180°轴的诱导性纹症下测量的.
主要成果:
- 在双焦和三焦内膜眼镜中,视力敏度随着头的增加而降低.
- 通过EDOF IOLs,在所有诱导的眼水平上保持了临床上可接受的近视.
- 在远距离和近距离两种情况下,EDOF IOLs表现出VA减轻的最高光值.
结论:
- 与双焦和三焦内膜眼镜相比,EDOF内膜眼镜表现出较高的耐受性对残留白症.
- 与规则相比,对远程VA的影响较小,对所有IOL的规则异常的纹有较小的影响.
- 针对每种内膜眼镜类型,针对临床上可接受的由于纹症而导致的VA减轻的建议值被确定.

2.8K
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...

01:27Open Angle Glaucoma: Treatment
453
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.
