概括
微笑Xtra与预防性交叉连接相结合,在角膜薄或边界地形的患者中提供安全有效的近视治疗. 这种手术成功地纠正视力并防止角膜脱落,确保在手术后12个月内稳定的折射结果.
科学领域:
- 眼科医生 眼科 眼科
- 折射手术是一种折射手术.
- 角质生物力学 角质生物力学
背景情况:
- 患有角膜薄或边缘角膜地形的患者在折射手术后呈现较高的角膜脱落风险.
- 对于这些高风险患者来说,标准的小切口镜片提取 (SMILE) 可能不足.
- 预防性角膜交联是一种潜在的补充,可以减轻与脆弱角膜的折射手术相关的风险.
研究的目的:
- 评估SMILE Xtra技术在患有角膜薄和/或角膜边界拓的患者中纠正近视的疗效和安全性.
- 评估SMILE Xtra与预防性交叉链接后的折射结果和角质脱落的发生率.
主要方法:
- 五十三名近视患者 (105只眼睛) 患有近视,并处于形脱皮的风险中,接受了SMILE Xtra.
- 预防性交叉连接是通过将利博弗拉应用于角膜口袋,然后加快紫外线照射 (SUB-400协议) 来进行的.
- 数据收集包括Scheimpflug分析,角膜生物力学特性,光学连贯性断层扫描 (OCT),以及在12个月的随访期间进行的标准眼科检查.
主要成果:
- 手术后的球形等效折射在平面附近稳定 (-0.29±0.47 D在6个月) 与良好的未经校正的视力敏度 (0.94±0.11在第7天).
- 手术后平均角膜测量保持稳定,手术后中央角膜厚度显著降低.
- 在第一天发现了暂时的角膜,但在第7天就消失了;在随访期间没有观察到折射回归或角膜脱落.
结论:
- 结合预防性交叉链接,SMILE Xtra是患有角膜薄或边界地形患者近视的可行治疗选择.
- 该技术表现出良好的折射结果,并有效地防止了角膜脱落的发展,为高危人群提供了安全的手术解决方案.

1.5K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

01:27Open Angle Glaucoma: Treatment
393
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.

01:28Angle Closure Glaucoma: Treatment
437
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...

01:16Focusing of Light in the Eye
2.5K
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...
