概括
这项研究展示了一种创新的扩展单视技术,使用两种不同的眼内透镜 (IOL) 进行折射透镜交换 (RLE). 这种方法在所有距离上都能实现出色的视力和高眼镜独立性,副作用最小.
科学领域:
- 眼科 眼科
- 折射手术
背景情况:
- 在折射性透镜交换 (RLE) 中,眼镜的独立性是主要目标,尤其对于年轻的患者来说,他们有很高的期望.
- 本研究研究了一种新的扩展单眼视觉策略,使用主导眼中的单焦眼内透镜 (IOL) 和非主导眼中的扩展焦深 (EDOF) IOL.
- 目的是提高全程视觉性能,同时减少光学现象.
研究的目的:
- 在接受折射性透镜更换 (RLE) 的患者中评估扩展单视方法的视觉结果和眼镜独立性.
主要方法:
- 一个回顾性队列研究,涉及38名双侧RLE的长视患者.
- 患者在主眼中接受单焦无球体内镜,在非主眼中接受旋转不对称的双焦EDOF内镜.
- 视觉敏度 (距离,中等,近距离),双眼失焦曲线,对比度灵敏度,立体敏度,光学现象,眼镜独立性和患者满意度进行了评估.
主要成果:
- 术后双眼视力未经纠正的平均视力在远距离 (- 0. 03 logMAR),中间 (- 0. 08 logMAR) 和近距离 (0. 04 logMAR) 均为优异.
- 功能性视力扩展到广泛的失焦范围 (- 3. 25 D到+ 1. 00 D),其中84%的患者实现了完全的眼镜独立.
- 对比度保持在正常范围内,立体敏度保持在97%,光学现象最小.
结论:
- 这种新的扩展单眼视觉方法结合了单焦和EDOF眼镜,在所有距离上都能提供出色的未经校正的视觉.
- 这种策略提供了高度的眼镜独立性和最小的不良视觉影响,使其成为RLE候选人的多焦点内腔镜的可行替代品.

01:27Open Angle Glaucoma: Treatment
557
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
669
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...

01:25Glaucoma: Overview
745
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
