概括
裂纹灯和波面异常测量方法在重新调整手术期间同样有效地评估托里克眼内透镜 (TIOL) 轴. 这两种技术都会在TIOL重新定位后改善视力和减少纹.
科学领域:
- 眼科医生 眼科 眼科
- 折射手术是一种折射手术.
- 眼科技术 眼科技术
背景情况:
- 托里克眼内透镜 (TIOLs) 纠正了白,但需要精确的轴对齐以获得最佳结果.
- 对TIOL轴的准确评估对于成功的调整手术至关重要.
- 目前用于轴评估的方法包括裂纹灯检查和波面异常测量.
研究的目的:
- 为了比较裂灯方法与波面异常测量的有效性,用于评估托里克眼内透镜 (TIOL) 轴.
- 通过使用这两种评估方法,评估胸部调整手术的结果.
主要方法:
- 一项回顾性研究分析了52只接受TIOL调整手术的眼睛.
- 在手术前和手术后,TIOL轴的评估使用了裂纹灯和波面异常测量方法.
- 眼睛被分为两组:重新调整到原始位置 (第一组) 或波导向轴 (第二组).
主要成果:
- 在切割灯 (44.9° ±20.0°) 和波面异常测量 (47.1° ±19.5°) 之间,手术前的错位测量结果相似.
- 调整后的失调也可以比较:5.2° ±5.2° (裂纹灯) 和4.7° ±5.1° (波面异常测量) (P = 0.615).
- 这两种方法都导致未经校正的视敏度 (UCVA) 显著改善,以及折射筒的减少.
结论:
- 裂灯法是评估TIOL轴的波面异常度的可行和有效替代方法.
- 胸部调整手术是一种安全的手术.
- 基于这两种方法的调整同样改善了UCVA,并减少了剩余的折射气.

Angle Closure Glaucoma: Treatment
563
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...

Open Angle Glaucoma: Treatment
480
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.
