概括
与标准的单焦IOL相比,xact Mono-EDoF ME4眼内透镜 (IOL) 提供了改善的中间视力. 这种增强的焦点深度IOL对于白内障患者来说是安全有效的.
科学领域:
- 眼科医生 眼科 眼科
- 生物医学工程 生物医学工程
- 医疗器械 医疗器械
背景情况:
- 白内障手术通常涉及单聚焦眼内透镜 (IOL).
- 增强焦点深度 (EDOF) IOLs旨在改善视觉功能.
- xactTM Mono-EDoFTM Model ME4是一种全新的EDOF IOL.
研究的目的:

- 为了比较单-EDoF IOL 与一个无球单焦 IOL (TECNIS 1 件 IOL 模型 ZCB00).
主要方法:
- 在英国,法国和葡萄牙进行了一项前性多中心随机临床试验.
- 双边白内障的成年人接受了单一EDoF或单聚焦IOL.
- 视力敏度 (距离,中等) 和视力障碍是主要和次要终点.
主要成果:
- 与对照组相比,单一EDoF IOL组显示出明显更好的未经校正的距离视敏度 (UDVA),未经校正的中间视敏度 (UIVA) 和距离校正的中间视敏度 (DCIVA).

01:27Open Angle Glaucoma: Treatment
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.

01:28Angle Closure Glaucoma: Treatment
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...
