概括

以Q值为导向的秒激光辅助的 in situ 角质化 (FS-LASIK) 是安全有效的,用于治疗高化 (HA) 和低化 (LA). 虽然HA患者经历了更多的高阶异常 (HOA),但外科手术后的一年后的结果保持稳定.

科学领域:

眼科医生眼科眼科
折射手术是一种折射手术.
角膜外科手术角膜外科手术

背景情况:

Femtosecond激光辅助的 in situ 角膜修复 (FS-LASIK) 是一种首选的白症治疗方法.
由于角膜重塑和更高阶异常 (HOA) 的增加,高形 (HA) 存在挑战.
以Q值为指导的FS-LASIK优化了角膜无球性,但其在HA患者中的有效性需要进一步研究.

研究的目的:

评估Q值指导的FS-LASIK1年视觉,角膜生物力学和异常测量结果.
为了比较高白症 (HA) 和低白症 (LA) 患者之间的结果.

主要方法:

一项对120名接受Q值指导FS-LASIK的患者 (60 HA, 60 LA) 的前性研究.
评估包括视力敏度,Pentacam HR (HOAs),Corvis ST II (生物力学) 和Alpins矢量分析.
在手术前和手术后的1,3,6,12个月收集的数据.

主要成果:

100%的患者在12个月内达到未经纠正的远距离视力敏度≥20/20,没有纠正的远距离视力敏度下降.
在HA和LA组之间,安全性和有效性指数是可比的 (P>0.05).
在HA患者中,残留HOA和手术诱导的纹症较高,但生物力学变化在两组中均相似稳定.

结论:

以Q值为指导的FS-LASIK对HA和LA患者都是安全有效的,表现为稳定的1年结果.
HA患者呈现较高的残留HOA,这表明优化外科手术参数 (如光区大小) 有潜在的好处.

关键词:

激光手术 (LASIK) 是一种激光手术.这就是Q值.角膜生物力学角膜生物力学有引导的FSFS.高度的白症是一种高白症.更高的更高的更高的顺序异常顺序异常顺序异常视觉上的结果.

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...

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...

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...
