概括

新:YAG (Nd:YAG) 囊切除术对于使用可调光眼内透镜 (LALs) 的伪眼睛是安全有效的,即使在调整过程中出现后囊暗. 在这两组中,折射结果在手术后保持稳定.

科学领域:

眼科医生眼科眼科
医疗技术医疗技术医学技术
外科手术的结果

背景情况:

后囊化 (PCO) 是白内障手术后的一个常见并发症.
可调节光线的眼内透镜 (LALs) 在术后提供可调节的折射校正.
在调整期内,LAL患者的Nd:YAG囊切除术的安全性尚未得到充分证实.

研究的目的:

为了评估Nd:YAG囊切除术在假眼中使用LALs的安全性和折射结果.
为了比较 Nd:YAG 囊切除术在 LAL 光输送装置锁定治疗之前和之后进行时的结果.

主要方法:

一项回顾性研究比较了两组接受Nd:YAG囊切除的LAL患者.
第一组在锁定治疗之前进行了囊切除;第二组在治疗后进行了囊切除.
折射结果 (球体,圆柱体,轴,SE,UDVA,CDVA) 在手术前和后被分析.

主要成果:

在485个LAL植入物中,Nd:YAG囊切除术在38只眼睛 (2.6%) 中进行.
术后纠正远距离视力敏度 (CDVA) 在两组中都显著改善.
没有观察到球体,圆柱,轴,球体等效 (SE) 或未经纠正的远距离视力敏度 (UDVA) 的统计学意义上的变化.

结论:

Nd:YAG囊切除术是LAL患者PCO的安全有效治疗方法.
该程序不会显著改变LAL眼睛的折射结果,无论与锁定治疗相比时间如何.
LAL患者可以接受Nd:YAG囊切除术,而不会影响折射校正.

Angle Closure Glaucoma: Treatment

Angle 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...

Open Angle Glaucoma: Treatment

Open 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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Glaucoma: Overview

Glaucoma: Overview

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...
