概括
囊张力环 (CTR) 植入增强了高度近视患者眼内透镜 (IOL) 的旋转稳定性. CTRs减轻了镜头旋转效应,特别是在眼睛有厚厚的晶状镜头,而不会显著影响IOL倾斜或分散.
科学领域:
- 眼科医生 眼科 眼科
- 生物医学工程 生物医学工程
背景情况:
- 高近视对眼内透镜 (IOL) 植入具有独特的挑战.
- 确保IOL旋转稳定性对于最佳的视觉结果至关重要.
- 在这些情况下,囊张力环 (CTR) 在控制内腔眼镜中的作用需要进一步研究.
研究的目的:
- 为了比较CTR植入和没有CTR植入的高度近视患者中循环触觉IOL的旋转稳定性,倾斜性和分散性.
- 评估CTR对眼睛内视镜定位的影响,眼睛轴长度≥26.00mm.
主要方法:
- 这是一项随机对照试验,涉及72名高度近视的患者,接受了化和IOL植入.
- 患者被分配到CTR植入组或没有CTR组.
- 在多个术后时间点使用扫描源光学连贯性断层扫描来评估IOL轴向,倾斜和分散.
主要成果:
- 从手术结束到术后3个月,CTR组与非CTR组相比,绝对IOL旋转显著较低 (P = .018).
- 植入CTR显著降低了眼睛中的内视镜旋转,眼睛有厚的晶体透镜 (P = .041).
- 虽然CTR组的倾斜和分散值略低,但这些差异在统计学上并不显著 (P > .05).
结论:
- 囊张力环植入改善了高度近视的眼睛中环形眼镜的术后旋转稳定性.
- CTRs有效地减轻与厚厚的晶体镜片相关的内视镜旋转效应.
- 在这种患者群体中,CTR植入并没有显著影响IOL倾斜或分散.

01:16Focusing 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...

01:27Open Angle Glaucoma: Treatment
963
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
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...

01:25Glaucoma: Overview
1.3K
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...
