背景情况:
- 之前进行过激光折射手术 (LASIK/PRK) 的患者的白内障手术在实现精确的折射结果方面提出了独特的挑战.
- 可调光透镜 (LAL) 通过允许术后折射调整提供了一个潜在的解决方案.
- 在这个特定的患者群体中评估第二代LAL (ActivShield) 的性能至关重要.
研究的目的:
- 评估第二代LAL在以前接受LASIK或PRK治疗的白内障患者的视觉结果.
- 为了评估共同管理的有效性,在这个队列中对LAL治疗的开放式访问方法.
- 为了确定与激光折射手术史眼睛的LAL实现的折射精度和视力敏度.
主要方法:
- 追溯的病例系列的患者接受了白内障手术的第二代LAL.
- 患者有LASIK和/或PRK的病史,并具有透性折射标.
- 手术后的紫外线照射治疗是通过共同管理的开放访问系统进行的. 视力敏度,球形等价值 (SE) 和残留气是主要结果.
主要成果:
- 前经过激光折射手术的33名患者 (34只眼睛) 接受了第二代LAL.
- 82.4%的未经校正的远距离视敏度 (UDVA) 达到20/20或更高; 26.5%的视敏度达到20/15或更高.
- 平均SE为0.01±0.31 D,其中97.1%在平面的±0.50 D范围内. 平均残留气为-0.28 ± 0.32 D,其中88.2%在±0.50 D范围内.

6.1K
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,...

01:28Angle Closure Glaucoma: Treatment
534
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...

01:25Glaucoma: Overview
595
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...
