概括
在角膜升或上皮移除后,发生循环扭转变化. 为了获得最佳的折射手术结果,在升起后应进行虹膜注册,以最大限度地减少残留的纹.
科学领域:
- 眼科医生 眼科 眼科
- 折射手术是一种折射手术.
- 角质生物力学 角质生物力学
背景情况:
- 角膜折射手术旨在通过重塑角膜来纠正视力错误.
- 准确的角膜对齐对于成功的手术结果至关重要.
- 带有虹膜注册的眼睛跟踪系统有助于减轻旋转运动,即眼睛的旋转运动.
研究的目的:
- 为了比较角膜手术前后的循环扭转测量.
- 为了评估FemtoLASIK中片升高与酒精辅助PRK中上皮质去除对循环扭转的影响.
- 为了确定虹膜注册在折射手术中的最佳时间.
主要方法:
- 追溯队列研究分析了152只接受FemtoLASIK或酒精辅助PRK的眼睛.
- 使用WavescanTM和VISX Star S4虹膜注册仪器,在术前和术后测量了循环扭转.
- 收集和分析数据以比较角膜旋转变化的变化.
主要成果:
- 费米托拉西克 (FemtoLASIK) 显示,在翻盖升高后,循环扭转显著增加 (平均变化为2.8°与2.3°相比,p=0.01).

01:28Angle Closure Glaucoma: Treatment
374
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
358
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.
