概括

自动光线追踪引导的LASIK (波光加) 与波面优化的LASIK相比,显示了非劣质的折射结果. 这种先进的治疗方法提供了可比的视敏度和更高的精度,而不需要明显的折射.

科学领域:

眼科医生眼科眼科
折射手术是一种折射手术.
激光视力校正激光视力校正

背景情况:

激光辅助 in situ 角膜切除术 (LASIK) 是一种常见的折射手术.
在LASIK技术的进步旨在改善折射和视觉结果.
自动定制的光线追踪和波优化的方法代表了 LASIK 切除计划的不同策略.

研究的目的:

为了比较自动定制的光线跟踪引导的LASIK (波光加) 与波面优化的LASIK.
为了评估两个LASIK方法之间的个体内折射和视力敏度结果.
为了评估波光加在实现目标折射结果的非劣等性.

主要方法:

前性,随机,双盲,对侧眼对比研究.
三十名近视和近视的患者在一只眼睛接受了波光加,在另一只眼睛接受波光前端优化的LASIK.
测量结果包括明显折射球体等价值 (MRSE),视力敏度 (UDVA,CDVA) 和3个月的安全性/有效性指数.

主要成果:

波光加在±0.50 D范围内实现了100%的MRSE,而波面优化的LASIK (noninferior,P < 0.001) 则达到90.0%.
平均MRSE为波光加值的-0.05 D,而波面优化的LASIK为-0.16 D (P = 0.039).
两种方法都显示了可比的未经纠正和纠正的距离视力敏度,高百分比达到20/20或更好.

结论:

自动射线追踪指导的LASIK (波光加) 是安全有效的,产生可比于波面优化LASIK的视觉结果.
波光加获得非劣质折射结果和略高的MRSE精度,没有明显的折射.
这项研究支持自动光线追踪对个性化LASIK治疗的有效性.

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...
