概括

基于Vergence公式 (VRF) 的方法,VRF-L和VRF-GL,在放射性角膜切除术 (RK) 后显示高精度的眼内透镜 (IOL) 功率计算. 这些配方为眼睛的白内障手术提供了可靠的结果,这些眼睛之前有RK.

科学领域:

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:

放射性角膜切除术 (RK) 改变了角膜曲率,在随后的白内障手术中复杂化了眼内透镜 (IOL) 功率计算.
现有的IOL计算公式可能会在具有先前RK的眼睛中表现出较低的精度.

研究的目的:

为了评估Vergence公式 (VRF) -L和VRF-GL IOL功率计算方法的准确性,眼睛已经接受了先前的RK.
将VRF-L和VRF-GL的性能与其他九种已建立的IOL计算公式进行比较.

主要方法:

使用SS-OCT生物识别 (IOLMaster 700) 来从78只眼睛收集数据,这些眼睛之前有RK.
将VRF-L和VRF-GL与9种配方进行比较,包括巴雷特True K,海吉斯,霍弗Q,霍拉代1&2,PEARL-DGS,SRK/T和T2.
使用根平均平方绝对误差 (RMSAE),中位数绝对误差 (MedAE) 和特定预测误差 (PE) 范围内的眼睛百分比来分析结果.

主要成果:

VRF-GL,VRF-L和Haigis公式显示了最低的RMSAE和MedAE值,表明了高精度.
VRF-L,VRF-GL和Haigis实现了最高比例的眼睛,预测误差在±0.50 D和±1.00 D之间.
巴雷特真K公式的可预测性相对较低.

结论:

VRF-L和VRF-GL方法提供了精确的眼睛在RK后的IOL功率计算,与现有的标准相比.
海吉斯公式是一种可行的替代方案,提供高百分比的眼睛在±1.00 D的预测误差范围内.

Open Angle Glaucoma: Treatment

Open Angle Glaucoma: Treatment

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

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...
