Treatment
Although surgery is the only remedy for cataracts, it is almost never an emergency. Most cataracts cause no problem other than reducing a person's ability to see, so there is no harm in delaying surgery.

Early cataracts may be managed with the following measures:
- Stronger eyeglasses or contact lenses
- Use of a magnifying glass during reading
- Strong lighting
- Medication that dilates the pupil. (May help some people with capsular cataracts, although glare might be a problem with this treatment.)
It is important to note, however, that there are no treatments that will prevent cataract formation or progression or that make a cataract disappear.
Progression of Cataracts. Patients and their families usually have plenty of time to consider options carefully and discuss them with an ophthalmologist. There is no constant rate at which cataracts progress:
- Some develop to a certain point and then stop.
- Even if a cataract does progress, it may be years before it interferes with vision.
- Only in a very few, very rare circumstances is it necessary that cataract surgery be performed immediately.
Choosing Cataract Surgery
Each year about 1.5 million cataract operations are performed, making it the most common operation in the US for people over 65. Cataract surgery may be the oldest procedure in the world, having been introduced to Europe from India by Alexander the Great's army.
In the past, cataract surgery was not performed until the cataract had become well developed. Newer techniques, however, have made it safer and even more efficient to operate in earlier stages. In fact, modern cataract techniques not only remove cataracts but are also becoming important procedures for correcting astigmatism. Cataract surgery improves vision in up to 95% of cases and prevents millions of Americans from going blind.
