概括
这项研究评估了多焦点隐形眼镜功率配置文件. MyDay多焦镜头显示的辐射功率与其他品牌相似,但高附加值可能会导致因偏差而导致适配问题.
科学领域:
- 眼科医生 眼科 眼科
- 眼镜测量是指眼睛的测量.
- 生物医学工程 生物医学工程
背景情况:
- 多焦点隐形眼镜 (MCL) 为长视障碍纠正提供了一个解决方案.
- 同时视觉MCLs可能会由于多个光学区域导致视觉妥协.
- 修改后的单视觉设计旨在优化不同距离的视觉.
研究的目的:
- 为了评估MyDay多焦点隐形眼镜 (CooperVision) 的体外功率概况,它具有三种添加功率.
- 为了将MyDay多焦镜头功率配置与其他商业MCL (Proclear和Clariti,CooperVision) 进行比较.
主要方法:
- 测量了MyDay (低,中,高添加),Proclear (单添加) 和Clariti (高添加) MCL 的体外功率概况.
- 对功率+0.00 D,±1.00 D,±3.00 D和±5.00 D.进行了测量.
- 使用NIMO TR1504仪器进行功率概况评估.
主要成果:
- MyDay低和中添加镜头表现出渐进的辐射功率配置,类似于Proclear镜头.
- 中等添加MyDay镜头显示了+0.50 D偏移,这表明非主导眼睛的距离过度校正.
- MyDay高附加镜头显示了明显的环状功率区域,与Clariti高附加镜头相似,由于球形偏差而导致显著的外围功率变化.
结论:
- MyDay多焦镜头显示的辐射功率配置文件与已建立的CooperVision MCLs保持一致.
- 高添加MyDay镜头的外围距离区域表现出未经纠正的球形偏差.
- 这种异常可能导致患者的不一致性和视觉障碍.

01:16Focusing of Light in the Eye
3.3K
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...

01:28Angle Closure Glaucoma: Treatment
705
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...
