概括
在75%的眼睛中,长期将后囊与眼内透镜 (IOL) 光学实现了. 这提高了视觉质量,并减少了对酸石榴石 (Nd:YAG) 激光囊切除的需求.
科学领域:
- 眼科医生 眼科 眼科
- 生物材料科学 生物材料科学
- 医学光学医学光学
背景情况:
- 后囊变暗 (PCO) 和需要胺合伊石榴石 (Nd:YAG) 激光囊切除术是眼内透镜 (IOL) 植入后常见的并发症.
- 内膜眼镜的表面修饰可以影响它们与眼睛组织的相互作用,可能会影响长期的结果.
研究的目的:
- 为了评估后部囊 (PC) 与植入紫外线 (UV) /臭氧表面修饰IOLs的眼睛中的IOL光学相对应的位置.
- 为了确定PC-IOL光学应用对Nd:YAG激光囊切除率和整体视觉质量的影响.
主要方法:
- 一个潜在的干预案例系列,涉及100只眼睛植入UV/臭氧表面修饰的疏水性烯酸IOLs.
- 用前段光学连贯性断层扫描 (ASOCT) 评估了后部囊-光学对应.
- 二级结局包括Nd:YAG囊切除率和视觉质量测量,在2年的随访期间使用射线追踪异常测量.
主要成果:
- 完整的PC-IOL光学位从术后第一天的4%增加到2年后的75%.
- 具有完整PC-IOL光学置的眼睛显示出明显更好的视觉质量,包括更高的斯特雷尔比率和改进的调制转移功能 (MTF).
- 持续的PC-IOL非附着与更高的PCO发病率和更大需要Nd:YAG激光囊切除有关.
结论:
- 在接受UV/臭氧表面修饰IOL的大多数患者 (75%) 中,可以实现长期的PC-IOL光学应用.
- 实现完整的PC-IOL光学置与降低的Nd:YAG囊切除率有关.
- 卓越的视觉质量与完整的PC-IOL光学应用有关.

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
1.7K
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...
