Summary
Phacoemulsification is safe for eyes with long anterior zonules (LAZs). This cataract surgery technique achieved 100% successful capsulorhexis without complications, ensuring excellent visual outcomes.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Cataract Surgery
Background:
- Long anterior zonules (LAZs) present unique challenges during cataract surgery.
- Phacoemulsification requires careful management of zonular integrity.
Purpose of the Study:
- To evaluate the safety and efficacy of phacoemulsification in eyes with long anterior zonules (LAZs).
Main Methods:
- Retrospective analysis of 65 eyes with LAZs undergoing phacoemulsification by a single surgeon.
- Phacoemulsification performed with capsulorhexis sacrificing the LAZs.
- Primary outcomes: capsulorhexis extension, intraoperative rescue, and complications. Secondary outcomes: refractive accuracy.
Main Results:
- 100% successful capsulorhexis without extension or intraoperative rescue.
- A low incidence of intraoperative complications (1.5%, one posterior capsular rupture).
- High refractive accuracy: 77% within ±0.5 D and 94% within ±1.00 D of target refraction.
Conclusions:
- Phacoemulsification is a safe and effective method for cataract extraction in eyes with LAZs.
- Sacrificing LAZs during a 360-degree capsulorhexis is well-tolerated.
- The procedure leads to favorable visual and refractive outcomes.

01:28Angle Closure Glaucoma: Treatment
1.0K
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
1.1K
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
900
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.

01:16Focusing of Light in the Eye
5.0K
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...
