概括

激光不对称角膜切除术 (L-LAK) 在疑似角膜 (KCS) 患者中改善了角膜规律性. 这种角膜重塑技术在手术后一年内提高了视力敏度,减少了角膜的不规则性.

科学领域:

眼科医生眼科眼科
角膜外科手术角膜外科手术
折射手术是一种折射手术.

背景情况:

疑似眼 (KCS) 眼睛呈现不规则的角膜形状.
评估角膜规律性对于KCS管理至关重要.
激光不对称角膜切除术 (L-LAK) 是一种新的角膜重塑技术.

研究的目的:

评估L-LAK在KCS患者角膜重塑方面的疗效.
评估L-LAK对角膜规律性和视觉结果的影响.
为了确定L-LAK在预防手术后抽方面的安全性.

主要方法:

对20名KCS患者的34只眼睛进行了回顾性病例对照研究.
术前和1年术后数据的比较.
折射的评估,未经纠正的远视敏度 (UDVA),角膜测量,角膜对称性 (SUM和距离).

主要成果:

球体等价值 (SE) 和Kmax (P=0.001) 的显著改善.
通过减少SUM和DISTANCE显示的增强的角膜对称性.
79.4%的眼睛实现了20/20或更好的UDVA.
没有观察到术后角膜脱光症的病例.

结论:

在KCS患者中,L-LAK有效改善角膜对称性.
这种技术可以减少焦点角膜度.
在KCS中,L-LAK在角膜重塑方面表现出有利的1年结果.

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...
