概括
小切口镜片提取 (SMILE) 提供了较少的角膜高阶异常比 Femtosecond激光辅助 in situ 角质疏散 (FS-LASIK). 实现定期有效的光学区域和监测上皮质厚度对于预防高近视患者近视回归至关重要.
科学领域:
- 眼科医生 眼科 眼科
- 折射手术是一种折射手术.
- 角膜异常 角膜异常
背景情况:
- 评估角膜高阶异常 (HOA) 在近视纠正手术后五年.
- 通过比较秒激光辅助的 in situ 角膜切除 (FS-LASIK) 和小切口镜片提取 (SMILE).
- 调查影响近视回归和有效光区 (EOZ) 形态的因素.
研究的目的:
- 评估和比较五年术后FS-LASIK和SMILE之间的角膜HOA.
- 确定EOZ形态,折射结果和近视回归之间的相关性.
- 评估上皮质厚度 (ET) 对折射稳定的影响.
主要方法:
- 横截面研究分析了来自116个FS-LASIK和126个SMILE眼睛的数据.
- 收集的数据包括折射结果,角膜地形,HOA,ET和视力质量 (QoV) 问卷.
- 基于曲率图的EOZ形态分类 (均,领,半圆形,钥匙孔,不规则).
主要成果:
- FS-LASIK显示的球形偏差比SMILE更大.
- 半圆形的EOZ模式与水平分散和昏迷增加相关.
- 钥匙洞EOZ模式与更负面的球形偏差,焦点困难和高近视的近视回归风险显著增加有关.
- 表皮厚度的差异增加了近视回归的可能性.
结论:
- 与FS-LASIK相比,微笑似乎会导致较少的HOA.
- 在高近视症中,实现中心,规律的EOZ对于视觉质量至关重要.
- 监测上皮质重塑是防止近视后手术回归的关键.

Focusing of Light in the Eye
5.4K
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
1.2K
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...
