Cataract is a very common eye condition, caused by a clouding of the lens inside your eye. Cataracts usually develop in later life and cause the vision to become blurred or misty.
What causes cataract?
Most cataracts are simply an age-related change that many of us will experience eventually. However, other factors that predispose you to develop cataracts include smoking, excessive amounts of alcohol, poor diet, over exposure to sunlight, corticosteroids, previous eye injury or surgery, diabetes and uveitis.
How is cataract treated?
The good news is that cataract surgery is now a routine operation with a very low risk of complications. Modern cataract surgery involves removing the cloudy lens and replacing it with a clear plastic implant lens. The procedure is usually carried out under local anaesthetic, so you can normally return home the same day.
What happens after my cataracts have been removed?
Most people can return to their normal activities within a couple of weeks. If you wore glasses before the operation you may find that your spectacle prescription needs updating, but it is best to wait for a few weeks to let your eyes settle down before seeing your optometrist.
