眼科医生眼科眼科
折射手术是一种折射手术.
白内障手术手术白内障手术

背景情况:

辐射角切除术 (RK) 是一种折射性手术程序,用于纠正近视.
在RK之前的眼睛中,白内障手术可能会对折射性可预测性带来独特的挑战.
可调光透镜 (LAL) 在植入后提供可定制的折射校正.

研究的目的:

为了确定LAL植入在这个特定患者群体中的有效性和安全性.

主要方法:

在多个私人实践地点进行了回顾性,连续的案例系列.
包括有RK病史的眼睛,经历了用LAL植入物进行白内障手术,准了透.
收集的数据包括之前的折射手术细节,以及术后调整的时间/数量. 主要结局是未经校正的远距离视敏度 (UDVA) 和折射精度.

主要成果:

分析了77名患有各种RK类型 (4切,6切,8切,16切) 的77名患者的94只眼睛.
82%的眼睛实现了20/25或更好的UDVA,其中74%实现了20/20或更好的UDVA.
折射结果显示98%在±1.00 D范围内,88%在±0.50 D范围内,69%在±0.25 D范围内.

结论:

这种LAL在有RK史的眼睛中提供了有利的视觉和折射结果.
建议推迟术后的光调整,以便进行折射稳定.
在白内障手术后,LAL是后RK患者寻求改善未经纠正的视力敏度的可行选择.

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...

Photoreceptors and Visual Pathways

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

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...
