科学领域:
- 眼科医生 眼科 眼科
- 视网膜科学 视网膜科学
- 角质科学 角质科学
背景情况:
- 非衍射扩展视力眼内透镜 (IOLs) 提供了更好的视觉性能.
- 针对IOL植入的向策略,如吸血和迷你单视,影响视觉结果.
- 患者满意度和眼镜独立性是评估IOL疗效的关键指标.
研究的目的:
- 为了比较视觉结果和双边植入非衍射扩展视力眼内透镜 (IOL) 后的患者满意度.
- 为了评估向血与迷你单视 (-0.5 D) 的有效性,使用扩展视力IOL.
- 为了评估无助和纠正的视力敏度,中视对比度灵敏度,以及患者报告的结果.
主要方法:
- 一项前性随机对照试验,涉及70名接受双边白内障手术的患者.
- 患者接受了双边扩展视力IOLs (Vivity),随机分为吸管或迷你单视力目标.
- 术后评估包括视力敏度 (近距离,中等距离,远距离),对比度灵敏度,失焦曲线和验证的问卷.
主要成果:
- 双筒无助近视敏度 (UNVA) 在迷你单视组 (P = .03) 中显著改善.
- 在两组之间,中间和远距离的视力敏度以及中距离对比度灵敏度是可比的.
- 迷你单视组需要显著降低阅读添加值,并且在 -2.0 D和 -3.0 D之间的失焦曲线上显示出更好的视力敏度.
结论:
- 针对扩展视力IOL的迷你单眼视力,与双眼吸血症相比,它提供了优越的双眼UNVA.
- 这种策略保持了可比的远距离视觉敏度和中距离对比度灵敏度.

Open Angle Glaucoma: Treatment
1.1K
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.

Angle Closure Glaucoma: Treatment
1.6K
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...
