A cataract is a clouding of the lens in the eye, which leads to a decrease in vision. The lens, normally clear, becomes opaque, preventing light from passing through and focusing properly on the retina. Cataracts are often related to aging, but they can also develop due to injury, certain medical conditions (like diabetes), prolonged exposure to ultraviolet light, or as a side effect of certain medications. Common symptoms include blurry vision, difficulty seeing at night, sensitivity to light, and seeing “halos” around lights. Cataract surgery is a common treatment to restore vision.

Cataracts are typically treated with surgery, which is the most effective and common treatment. Here’s how it’s done:
1. *Surgery*: During cataract surgery, the cloudy lens in your eye is removed and replaced with an artificial lens (called an intraocular lens or IOL). This lens restores clear vision. The surgery is usually performed on an outpatient basis and is quick, lasting about 15 to 30 minutes per eye. There are two main types of surgery:
– *Phacoemulsification*: The most common method, where ultrasound waves are used to break up the cataract, and then it’s suctioned out.
– *Extracapsular surgery*: Used in more advanced cases, where the cloudy lens is removed in one piece.
2. *Non-Surgical Measures*: In the early stages of cataracts, surgery may not be needed right away. In these cases, some non-surgical options include:
– *Stronger eyeglasses* or *magnifying lenses*.
– *Brighter lighting* for reading and other activities.
– *Anti-glare sunglasses* to reduce light sensitivity.
Eventually, though, when vision becomes too impaired, cataract surgery is the most effective way to restore sight. It’s one of the safest and most successful procedures in modern medicine.
