A cataract is a clouding of the natural lens of the eye, which is located behind the iris (colored part of the eye) and the pupil. This clouding occurs when proteins in the lens clump together, causing it to become opaque or cloudy instead of clear. As a result, light cannot pass easily through the lens, leading to blurred or distorted vision.
Cataracts typically develop slowly over time and are most commonly associated with aging, although they can also be caused by other factors such as injury, medical conditions like diabetes, prolonged exposure to UV radiation, or the use of certain medications.
Symptoms of cataracts may include:
1. Blurred, cloudy, or dim vision
2. Increased difficulty seeing at night or in low light conditions
3. Sensitivity to glare from lights, including sunlight or headlights
4. Seeing halos around lights
5. Colors appearing faded or yellowed
6. Double vision in one eye
Initially, the effects of cataracts may be mild and not significantly impact vision. However, as the cataract progresses, it can interfere with daily activities such as reading, driving, or recognising faces. If left untreated, cataracts can eventually cause significant vision loss.
The treatment for cataracts usually involves surgical removal of the cloudy lens and replacement with an artificial intraocular lens (IOL).
Cataract surgery is a safe and effective procedure performed by ophthalmologists and is one of the most commonly performed surgeries worldwide. It can restore clear vision and improve quality of life for individuals affected by cataracts.
