WHAT ARE CATARACTS?
- A cataract is a clouding of the eye’s lens
- Normally the lens is clear, it focuses light onto the retina at the back of the eye which sends images to the brain
- A cataract blocks light needed for sight
- Your vision may become blurry or dim because light can’t pass properly through the lens to the retina
- A cataract is not contagious
- Surgery is the only treatment, cataracts cannot be treated with medicines
- Eye drops or other drugs will not dissolve a cataract or slow it progress
- It is a delicate operation, yet it is one of the safest operations done today
- More than 95% of surgeries are successful
- Most people need surgery when the cataract causes enough vision loss to interfere with work, play or other day-to-day tasks

- Blurred vision, double vision, ghost images, the sense of a film over the eyes
- Lights seem too dim for reading or close-up work, or you are dazzled by strong light
- Changing eyeglass prescriptions often, but the change may not seem to help your vision
- You may sometimes notice the cataract in eye. It may look like a milky or yellowish spot in the pupil (the center of your eye is normally black)
- Problems seeing become more noticeable as cataracts develop
- A cataract may develop quickly over months or slowly over years
- Many people reach the point where surgery is necessary
