概括
在小切口镜片提取 (SMILE) 手术中,不透明的泡层 (OBL) 与更的角膜和更薄的帽子有关. 虽然OBL暂时增加视觉偏差,但长期视觉质量仍然不受影响.
科学领域:
- 眼科医生 眼科 眼科
- 折射手术是一种折射手术.
背景情况:
- 小切口镜片提取 (SMILE) 是一种流行的折射手术程序.
- 不透明气泡层 (OBL) 形成是SMILE手术期间的潜在并发症.
研究的目的:
- 在SMILE手术中识别与OBL形成相关的风险因素.

- 测量了角膜高阶异常 (HOA),点传播函数 (PSF) 和调制转移函数 (MTF).
- 统计分析使用了通用估计方程和线性混合效应模型.
主要成果:
- 观察到的平均OBL面积为2.75%.
- 较大的OBL区域与更的角膜曲率,更薄的盖子厚度,更高的手术前角质量测量和更高的手术前球形值相关.
- 在SMILE后1周,OBL增加了角膜球形偏差和三叶草,但在1个月和3个月后,这些影响并不显著.
结论:

Focusing of Light in the Eye
2.8K
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...

Angle Closure Glaucoma: Treatment
505
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
574
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...

Open Angle Glaucoma: Treatment
453
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.
