眼内透镜植入眼内透镜植入

背景情况:

三片眼内透镜 (IOL) 的无内粘膜固定为后腔IOL植入提供了一种最小侵入性的替代方案.
托卡尔辅助技术促进了IOL触觉的外部化和固定在关道内.

研究的目的:

为了评估托卡尔辅助无内膜三片内膜眼镜固定的视觉和折射结果.
在这个特定的手术环境中,比较各种眼内镜片功率计算公式的准确性.

主要方法:

20名患者的20只眼睛经历了使用2.5毫米的道进行的三片IOL膜固定.
眼内透镜功率预测误差是使用巴雷特通用II,EVO,霍弗Q,Holladay1,HolladayII和SRK/T公式来计算的.

主要成果:

经过远距离校正的视力敏度在术后6个月显著改善,从0.66到0.17 logMAR (p < .001).
巴雷特公式产生了最低的中位数绝对预测误差 (0.73D),紧随其后的是EVO公式 (0.81D).
以巴雷特 (60.0%) 和EVO (55.0%) 公式实现了目标折射 ±1.00 D 的眼睛的最高百分比.

结论:

托卡尔辅助的内三片内膜眼镜固定提供了有利的视觉结果.
与标准白内障手术相比,这种技术的折射可预测性通常较低.

Glaucoma: Overview

Glaucoma: Overview

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...

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...
