Cataracts - What Happens Some cataracts grow larger or denser over time, causing severe vision changes. Severe cataracts can cause loss of independence for older adults as decreased vision may affect driving, working, reading, or hobbies. While cataracts can cause blindness, this is rare. Surgery is usually done before a cataract progresses far enough to cause blindness. A rare type of cataract can lead to glaucoma.

What to Expect With Cataract Surgery But replacing the cloudy cataract with a conventional artificial lens will at least improve their vision to some degree. Q: Can cataracts be prevented? A: Good question. There are many places in the world where cataract surgery isn’t available. As a result, an estimated 20 million people worldwide are totally blind from cataracts. So if you could delay the onset of this aging change, you might prevent severe vision loss in a significant number of people.

Cataract Surgery A cataract is an eye disease in which the normally clear lens of the eye becomes cloudy or opaque, causing a decrease in vision. The lens focuses light onto the back of the eye (the retina) so images appear clear and without distortion. The clouding of this lens during cataract formation distorts vision. Cataracts are usually a very gradual process of normal aging but can occasionally develop rapidly.

Cataracts A cataract in only one eye may be disturbing to a particular patient and may not cause significant symptoms in another patient. Cataracts usually do not harm your eye, so you can have surgery when it is convenient for you and when the cataract interferes with your daily activities. Once you understand the benefits and risks of surgery, you can make an informed decision about whether cataract surgery is right for you. In most cases, delaying cataract surgery will not cause long-term damage to your eye or make the surgery more difficult.
