Causes and Risk Factors What causes cataracts? The lens lies behind the iris and the pupil . It works much like a camera lens. It focuses light onto the retina at the back of the eye, where an image is recorded. The lens also adjusts the eye's focus, letting us see things clearly both up close and far away. The lens is made of mostly water and protein. The protein is arranged in a precise way that keeps the lens clear and lets light pass through it. But as we age, some of the protein may clump together and start to cloud a small area of the lens. This is a cataract. Over time, the cataract may grow larger and cloud more of the lens, making it harder to see. Researchers suspect that there are several causes of cataract, such as smoking and diabetes. Or, it may be that the protein in the lens just changes from the wear and tear it takes over the years. How can cataracts affect my vision?

No once catract is formed it cant go back, the catract has to be operated, even i was diabetic, i had diabetic cataract in the eye, doctor said the only remedy is to remove the cataract, and get well soon. its a minor operation on the eye i recovered soon. so i advice you to go for the surgery. one thing i want to mention is to control your sugars, if sugars are well controlled the chances of getting diabetes cataract is less.

Welcome to HealthcareMagic Forum.
In cataract the lens becomes hazy.The lens is removed by cutting up the eye from3to9o'clock position.putting in the artificial lens and giving5 stitches to close.In phacoemulsifiaction there is a probe with quartz crystal vibrating at 40 thousand cycles per sec.which emulsifies the lens and aspirates.An artificial lens is then put in by this 2.8mm 3.2 or 5.25mm openings

Hello, my mom is feeling heaviness and burning sensationin her eyes. She was informed she has cataracts, but says her eyesight has not been affected at all. Are the previous symptoms caused by the cataracts? Should she have the surgery already or can she wait until it begins affecting her vision? She is a very healthy 83 year old. Thank you.
