Summary
Corneal astigmatism significantly impacts vision in over 40% of cataract surgery patients. Toric intraocular lenses (IOLs) effectively treat astigmatism, improving visual acuity during cataract surgery.
Area of Science:
- Ophthalmology
- Refractive Surgery
Background:
- Corneal astigmatism affects over 40% of patients undergoing cataract surgery.
- Untreated astigmatism can lead to significant visual impairment.
Purpose of the Study:
- To review the diagnosis and management of corneal astigmatism.
- To evaluate the effectiveness of toric intraocular lenses (IOLs) in correcting astigmatism during cataract surgery.
Main Methods:
- Systematic literature search of PubMed, MEDLINE, Embase, and Cochrane Library (inception to October 2019).
- Included review articles, clinical trials, meta-analyses, and retrospective studies on astigmatism management and surgical outcomes.
- Evaluated IOL calculators and prediction accuracy for refractive outcomes.
Main Results:
- Toric IOLs demonstrated improved uncorrected visual acuity in patients undergoing cataract surgery.
- Advancements in diagnostic technology, toric IOLs, lens formulas, and imaging have enhanced astigmatism correction.
Conclusions:
- Toric IOLs are the standard of care for treating astigmatism during cataract surgery.
- Continuous innovation in technology and surgical techniques improves outcomes for astigmatism correction.

01:28Angle Closure Glaucoma: Treatment
1000
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...

01:27Open Angle Glaucoma: Treatment
865
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.

01:25Glaucoma: 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...
