概括
在Vivity扩展焦点深度眼内透镜 (IOL) 中,Symfony IOL在迷你单视觉中表现出类似的视觉性能. 然而,Vivity IOLs对患者造成的视力障碍较少.
科学领域:
- 眼科医生 眼科 眼科
- 生物医学工程 生物医学工程
- 临床研究 临床研究
背景情况:
- 扩展焦点深度 (EDOF) 眼内透镜 (IOL) 旨在改善多个距离的未经纠正的视力.
- 迷你单视,这是一种涉及轻微诱导异观差的技术,有时与EDOF IOL一起用于增强近视.
- 对比不同EDOF内膜眼镜的视觉性能和患者报告的结果对于手术决策至关重要.
研究的目的:
- 为了比较两个EDOF IOL (Symfony和Vivity) 之间的视觉性能和光学视觉障碍的发生率,当使用迷你单视觉策略植入时.
- 评估客观和主观的视觉结果,包括对比度敏感性和眼镜独立性.
主要方法:
- 进行了一项前性,检查员蒙面的随机临床试验,涉及接受双边Symfony (SYM) 或Vivity (VIV) IOLs的患者.
- 一只眼睛被定位为轻度近视失焦 (-0.75 D),用于迷你单视.
- 视力敏度,失焦曲线,对比度敏感性 (Pelli-Robson) 和患者报告的问卷 (眼镜独立性,视力质量) 在术后3个月被评估.
主要成果:
- 在Symfony和Vivity组之间,在远距离视觉敏度,失焦概况,对比度灵敏度或阅读速度方面没有发现显著差异.
- 在Symfony组中,80%的患者获得了近视敏度 (J2或更好),而在Vivity组中,这一比例为84%.
- 与Vivity IOL (34%) 相比,Symfony IOL (55%) (P = .0235) 的患者中明显较低的比例报告了令人不安的视力障碍.
结论:
- 与Symfony和Vivity EDOF IOLs一起的迷你单视觉被很好地容忍,并提供可比的视觉性能.
- 与Symfony EDOF IOL相比,Vivity EDOF IOL似乎与令人不安的视力障碍的发生率降低有关.
- 这些发现表明,患者报告的视力障碍可能是选择EDOF IOL用于迷你单视的关键差异化因素.

Angle Closure Glaucoma: Treatment
536
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...

Open Angle Glaucoma: Treatment
459
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.
