- 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:
- 低至中度近视纠正通常通过折射性手术程序实现.
- 小切口镜片提取 (SMILE) 和光折射性角膜切除术 (PRK) 是流行的手术选择.
- 了解对角膜生物力学和视觉结果的长期影响至关重要.
研究的目的:
- 为了比较SMILE和PRK之间的角膜生物力学参数,视觉结果和上皮重塑.
- 为了评估这两种折射手术技术的安全性和有效性,用于低至中度近视.
主要方法:
- 一个前性的,干预性的,随机的,比较性的研究.
- 40名患有低度至中度近视的患者的80只眼睛接受了双边SMILE或PRK.
- 视角生物力学 (Corvis-ST),视敏度,上皮图谱和更高阶异常被评估在手术前和手术后6个月.
主要成果:
- 在6个月后,SMILE和PRK组之间的视力敏度和球体等效结果是可比的.

01:27Open 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.

01:28Angle 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...
