Cataract
A cataract is a clouding of the natural lens inside the eye that affects vision. The lens, located behind the iris (the colored part of the eye), is normally clear and allows light to pass through and focus on the retina at the back of the eye. However, as we age, proteins in the lens can clump together and cause the lens to become cloudy. This cloudy area is called a cataract, and it can interfere with normal vision

Detailed Explanation
A cataract is a clouding of the natural lens in the eye, which can lead to blurry vision. It develops over time due to the aging process, but can also be caused by other factors like injury, certain medications, or medical conditions.
While cataract surgery is considered very safe, like any surgery, there are potential risks, including infection, bleeding, retinal detachment, and a slight risk of vision loss. However, serious complications are rare.
Age is the primary risk factor for cataracts. Other factors include exposure to UV radiation, smoking, certain medications, and medical conditions like diabetes.
A cataract can be diagnosed through a comprehensive eye examination, which includes visual acuity tests, a dilated eye exam, and other specialized tests to evaluate the clarity of the lens.
Currently, surgery is the only effective treatment for cataracts. There are no medications or exercises that can reverse cataract formation.
Cataract surgery involves removing the cloudy lens and replacing it with an artificial intraocular lens (IOL). The procedure is typically performed on an outpatient basis and is minimally invasive.
Common symptoms of cataracts include blurry or cloudy vision, difficulty seeing in low light conditions, sensitivity to glare, and seeing halos around lights.
Most patients experience a significant improvement in vision within a few days after surgery. Full recovery can take several weeks, during which you may need to use prescribed eye drops and avoid strenuous activities.
