概括

使用iTrace和LadarWave的自动折射与标准IOL相比,在增强单焦眼内眼镜 (IOL) 中的主观明显折射的一致性较小. 明显折射仍然是术后评估的关键,特别是在先进的内腔镜设计中.

科学领域:

眼科医生眼科眼科
光学工程是指光学工程.
生物医学光学生物医学光学

背景情况:

增强型单焦眼内眼镜 (IOL) 通过管理光学偏差来提高视觉质量.
基于波面的自动折射技术,如iTrace和LadarWave,旨在提供客观的折射测量.
比较主观明显折射和自动化方法之间的一致性对于理解不同IOL设计的术后折射结果至关重要.

研究的目的:

为了比较主观明显折射与基于波面的自动折射 (iTrace和LadarWave) 在眼睛中使用增强的单焦IOL (Tecnis Eyhance,RayOne EMV) 和标准的无球单焦IOL (Tecnis ZCB00).
通过使用自动化和主观折射方法,评估不同IOL光学设计的一致性和折射变异性.

主要方法:

对42名患者的84只眼睛进行了回顾性队列研究,这些患者植入了三个不同的单焦内腔眼镜.
手术后的评估包括视力敏度,主观明显折射和使用iTrace (光线追踪) 和LadarWave (Hartmann-Shack) 的自动折射.
使用统计方法评估了协议,包括布兰德-阿尔特曼分析和线性混合效应建模,以在方法和IOL类型之间比较球形等效 (SE).

主要成果:

主观的SE在IOL类型之间有显著差异,RayOne EMV显示出比Tecnis ZCB00更近视的结果.
自动折射表现出更大的可变性和较差的协议 (更广泛的协议极限,更少的眼睛在±0.50 D) 增强的单焦ILS与标准的无球体ILS相比.
iTrace和LadarWave都在增强的单焦IOL中表现出近视偏差与明显折射,而iTrace在标准IOL中显示出非显著的差异.

结论:

增强的单焦IOLs导致波面自动折射和主观明显折射之间的协议减少,而不是标准的无球单焦IOLs.
主观明显折射对于准确的术后评估至关重要.
自动折射测量应该被视为补充,特别是用于修改光学偏差的IOLs.

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...

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...

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...
