概括
扩展焦点深度 (EDOF) 眼内透镜 (IOL) 为患有轻度至中度不规则纹症的患者提供了良好的视觉结果. 这种白内障手术方法提供了出色的远视和中间视力,而不会显著影响结果.
科学领域:
- 眼科医生 眼科 眼科
- 眼镜测量是指眼睛的测量.
- 生物医学工程 生物医学工程
背景情况:
- 不规则的直觉症在白内障手术后实现最佳视力敏度时存在挑战.
- 扩展焦点深度 (EDOF) 眼内透镜 (IOL) 旨在提供视力范围,但它们在有不规则眼症的眼睛中的性能需要进一步调查.
研究的目的:
- 在接受双边EDOF IOL植入后,评估患有轻度至中度不规则纹症的患者的视觉和主观结果.
- 为了确定不规则的光标是否会影响EDOF IOL在白内障手术中的疗效.
主要方法:
- 进行了一项前性单中心临床试验.
- 28名患有轻度至中度不规则的患者使用AcrySof IQ Vivity EDOF IOL进行了双边白内障手术.
- 视力敏度 (CDVA,DCIVA,DCNVA,CNVA),对比度灵敏度,失焦曲线,波面异常度和主观结果 (VF-7) 在手术后4个月被评估.
主要成果:
- 患者获得了优异的平均单眼和双眼纠正距离视力敏度 (CDVA),分别为-0.01±0.08和-0.08±0.07 logMAR.
- 中间视敏度 (DCIVA) 也是有利的,双眼结果为0.08±0.08 logMAR.
- 失焦曲线表示视觉表现良好,直至-1.66D,患者报告日常活动难度较低.
结论:
- 在眼睛中,AcrySof IQ Vivity EDOF IOL在远距离和中距离的视觉表现非常好,眼睛具有低至中度的不规则合性.
- 双边植入EDOF内膜眼镜似乎是患有轻度至中度不规则眼症的患者的可行选择,因为它不会大大影响视觉结果.

Focusing of Light in the Eye
5.2K
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
1.1K
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
920
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.

Glaucoma: Overview
1.2K
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...
