What are Cataracts?
A cataract is a clouding of the lens of the eye. The normally clear lens lets light enter the eye. As it becomes cloudy, less light enters and vision becomes blurry. Cataracts are common with age and can occur in one or both eyes. The clouding of the lens usually happens slowly over time. But it can happen quickly.
What causes cataracts?
Cataracts may be caused by many things, including the following: |
| Aging |
| Diabetes or other eye diseases |
| Past eye infections, injuries, or surgery |
| Some medicines (such as steroids) |
| Too much ultraviolet (UV) light, especially from sunlight |
| Cataracts can also run in families |
|
|
What are the symptoms?
Cataracts are not painful. But you may notice these symptoms:
|
| Blurry vision |
| Details are hard to see |
| Glare when driving or reading |
| More light is needed to read |
| Some colors seem dull |
| Your prescription for glasses keeps changing |
| Double vision in one eye |
|
|
When is surgery needed?
Since cataracts develop slowly, you may not need surgery right away. Your doctor may ask you to get new eyeglasses. You may need to use more light for detailed tasks like reading or sewing. But if cataracts limit your activities, your doctor may suggest surgery.
Cataract Surgery
Surgery is the only way to remove a cataract and restore clear vision. During Surgery, the clouded lens is removed. It is replaced by new artificial lens. Usually only one eye is operated on at a time. After your eye has healed, your vision should be clearer.
