概括
这项研究将Artisan Aphakia镜头与阿法基眼中的FIL-SSF镜头进行了比较. 虽然这两种镜头都提供了相似的光学性能,但Artisan镜头由于更大的去中心化而增加了更高阶的偏差.
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:
- 二次透镜植入是阿法基眼睛的常见手术.
- 工匠阿法基亚和FIL-SSF镜头是用于纠正阿法基亚的眼内镜头选择.
- 了解透镜性能和影响光学质量的因素对于患者的治疗结果至关重要.
研究的目的:
- 为了比较Artisan Aphakia镜头和跨膜插头FIL-SSF镜头的异常特征.
- 为了评估倾斜和分散对这些眼内透镜的光学性能的影响.
主要方法:
- 对接受二次透镜植入的阿法基眼睛进行了回顾性观察性研究.
- 使用基于金字塔形波面异常计 (奥西里斯-T; CSO) 的波面分析.
- 通过前段光学连贯断层扫描 (MS-39;CSO) 测量倾斜和分散.
主要成果:
- 与FIL-SSF组 (0.39 ± 0.14毫米) 相比,在工匠组 (0.51 ± 0.16毫米) 中,分散率显著更高.
- 在工匠组 (0.29 ± 0.13 微米) 与FIL-SSF (0.23 ± 0.07 微米) 中,内部更高阶异常 (HOA) 较高.
- 没有下级偏差的PSF斯特雷尔比率 (PSFw2) 在FIL-SSF镜头 (0.28 ± 0.12) 与Artisan镜头 (0.23 ± 0.09) 相比,显着更好.
结论:
- 无论是Artisan还是FIL-SSF镜头,基于点扩散函数 (PSF) 斯特雷尔比率的总体光学性能都是可比的.
- 工匠镜头更容易分散,可能导致更高阶偏差增加和光学质量降低 (PSFw2).
- 仔细考虑镜头的位置和潜在的去中心化对于优化使用Artisan镜头的视觉结果很重要.

01:16Focusing of Light in the Eye
2.5K
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...

01:28Angle Closure Glaucoma: Treatment
436
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...
