概括

扩展焦点深度眼内透镜 (EDOF IOLs) 为近视眼提供了良好的视觉结果. 高近视患者具有特定的术后折射,获得更好的视觉质量和眼镜独立性.

科学领域:

眼科医生眼科眼科
生物医学工程生物医学工程
视光学测量视光学测量视光学测量

背景情况:

扩展焦点深度眼内透镜 (EDOF IOLs) 旨在改善多个距离的未经纠正的视力.
轴长 (AL) 和向折射可以影响EDOF IOL植入的结果.

研究的目的:

评估EDOF IOL植入在不同轴长度和向折射的患者中的客观视觉结果.
为了在不同的术后折射误差组中比较视觉性能.

主要方法:

追溯分析100个眼睛植入了EDOF IOLs.
眼睛按轴长分类 (AL<26毫米和AL≥26毫米).
基于术后球体等效 (SE) 的子组分析,评估3个月后未经校正的视力敏度 (UDVA,UNVA),对比度敏感度 (CS) 和眼镜独立性.

主要成果:

两组之间纠正距离视敏度 (CDVA) 没有显著差异.
在对照AL中,近视力在-1.50至-0.75SE组更好,远视力在-0.75至-0.00SE组更好.
在高近视症中,近视力在 -2.25至 -1.50 SE 组中更好,而远视力在 -0.75至 0.00 SE 组相比更差.
高近视患者 - - 1.50至 - - 0.75SE显示对比度敏感性降低,但90%的患者实现了眼镜独立.

结论:

EDOF IOL植入器在轴近视眼中提供了令人满意的视觉和折射结果.
在高近视患者中,术后折射率在-1.50至-0.75二光度之间,与其他近视结局相比,导致视觉质量优越和眼镜独立.

Focusing of Light in the Eye

Focusing of Light in the Eye

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...

Open Angle Glaucoma: Treatment

Open 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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Angle Closure Glaucoma: Treatment

Angle 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...
