概括
使用VISULYZE光学图的透透镜提取手术 (KLEx) 显示出对近视和视的纠正具有很高的疗效和安全性. 虽然年龄和近视严重程度可能会对结果产生轻微影响,但这项计划是个性化的.
科学领域:
- 眼科 眼科
- 折射手术
背景情况:
- 近视和眼是影响视力敏度的常见折射错误.
- 折射手术旨在纠正这些错误,改善未被纠正的视力.
- 角质折射镜片提取 (KLEx) 是一种用于视力纠正的手术技术.
研究的目的:
- 评估断镜片提取手术的疗效,安全性和可预测性.
- 评估VISULYZE产生的光学图在指导近视和的KLEX手术中的性能.
- 确定KLEX手术后的视觉结果和折射可预测性.
主要方法:
- 一项前性队列研究,涉及130名接受KLEX手术的患者 (260只眼睛).
- 在手术规划和指导中使用VISULYZE产生的名图.
- 评估结果包括未经纠正的远距离视力敏度 (UDVA),纠正的远距离视力敏度 (CDVA) 和球形等效 (SE) 在术后3个月.
- 根据患者年龄和手术前折射误差进行分组分析.
主要成果:
- 96% 的眼睛获得了20/20或更好的UDVA,其中96. 2% 保持或改善了CDVA.
- 观察到高可预测性,98. 1% 的眼睛在试图SE的±0. 50 D范围内,99. 2% 的眼睛在术后达到≤0. 50 D.
- 小组分析表明,年龄和高近视可能会微妙地影响UDVA和疗效,但白症的纠正仍然可比.
结论:
- 在VISULYZE指导下进行的KLEX手术是有效,安全和可预测的,用于纠正近视和眼.
- 在折射性外科手术中, 诺米图作为个性化手术规划的宝贵工具.
- 建议对特定患者群体进行进一步的研究,例如老年人和近视患者.

01:28Angle Closure Glaucoma: Treatment
669
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...

01:27Open Angle Glaucoma: Treatment
557
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.

01:16Focusing of Light in the Eye
3.2K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
