What is a cataract?
A cataract is a clouding of the normally clear lens of the eye. It can be compared to a window that is frosted or yellowed.
How fast does a cataract develop?
How quickly a cataract develops varies among individuals and may even be different between the two eyes. It is not possible to predict exactly how fast cataracts will develop in any given person.
How is a Cataract treated?
Surgery is the only way a cataract can be removed. No medications, dietary supplements or exercises have been shown to prevent or cure cataracts.
What causes a cataract?
The most common type of cataract is related to the aging of the eye. Causes of cataracts include:
- Family history
- Medical problems such as diabetes
- Injury to the eye
- Medications; especially steroids
- Long-term, unprotected exposure to sunlight
- Previous eye surgery
When should surgery be done?
Surgery should be considered when cataracts cause enough vision loss to interfere with your daily activities. Based on your symptoms you and your ophthalmologist should decide together when surgery is appropriate.
