概括
光折射性角膜切除术 (PRK) 和角膜折射性透镜提取 (KLEX) 能够有效地纠正近视性眼. PRK显示出更好的正,而KLEX具有更高的视敏度保留,这两种程序都产生了令人满意的结果.
科学领域:
- 眼科医生 眼科 眼科
- 折射手术是一种折射手术.
- 角膜外科手术 角膜外科手术
背景情况:
- 短视正是折射手术中常见的目标.
- 光折射性角膜切除术 (PRK) 和角膜折射性晶状体提取术 (KLEX) 是已确立的手术选择.
- 将这些程序之间的结果进行比较对于患者选择至关重要.
研究的目的:
- 为了比较PRK和KLEX后的视觉,折射和异常测量结果.
- 为了评估近视眼的两个手术技术的疗效和可预测性.
主要方法:
- 一项前性比较研究涉及74只近视和高眼的眼睛.
- 患者接受了PRK或KLEX手术.
- 手术前和手术后3个月和6个月的评估包括视敏度,折射,断层扫描和异常测量.
主要成果:
- 手术后六个月,PRK和KLEX都显示了可比的球体等价值 (P=0.06).
- 在PRK的结果中,残留白症的减少 (-0.58D vs. -0.80D,P=0.03) 和更高的校正指数 (0.99 vs. 0.81,P<0.001).
- 在KLEX中,未经纠正的视敏度保留率更高 (91%与65%相比),但PRK显示出更好的视敏度纠正.
结论:
- 无论是PRK还是KLEX都有效治疗近视眼,提供可预测的视觉结果.
- PRK 显示出优异的正,这可能是由于内置的 nomograms.
- KLEX可能会在高性性病例中不足以纠正性,可能是由于缺少诺莫格拉姆调整.

Focusing of Light in the Eye
5.2K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Angle Closure Glaucoma: Treatment
1.1K
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
928
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.
