- 折射手术是一种折射手术.
- 生物医学工程 生物医学工程
背景情况:
- 准确的眼内镜 (IOL) 功率计算对于成功的白内障手术至关重要.
- 之前的激光折射手术 (光折射角膜切除术,LASIK,SMILE) 显著复杂化了标准的IOL功率计算方法.
- 需要更新的建议和基于证据的方法来计算具有折射手术史的眼睛的IOL功率.
研究的目的:

主要成果:
- 近视后的LASIK/PRK眼睛通过平均多种计算方法或使用巴雷特True-K公式来实现最佳的折射结果.
- 超视后的LASIK/PRK眼睛也可以从巴雷特True-K公式中受益,尽管结果可能更可变.
- 结合测量到的角膜总功率,提高了近视后和近视后LASIK/PRK眼睛的准确性.

01:16Focusing of Light in the Eye
2.9K
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...

01:28Angle Closure Glaucoma: Treatment
540
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...

01:25Glaucoma: Overview
600
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

01:27Open Angle Glaucoma: Treatment
471
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.
