Cataracts

What is a Cataract?
A cloudy or opaque area in the lens of the eye is known as a cataract. This causes impaired vision.

Normal Vision Impaired Vision due to Cataracts

How do Cataracts Form?
A change in the chemical composition of the lens causes cataracts to form. It is not known why this change occurs.

What are the Symptoms of a Cataract?

  • hazy, fuzzy, or blurred vision
  • a change in an eyeglass prescription
  • the feeling of a thin film over the eyes
  • a change in the color of the eye's pupil from black to gray, yellow, or white
  • poor night vision
  • colors that seem to fade
  • light that appears especially bright.

Can Cataracts be Removed?
Yes. Surgeons can remove the cloudy lens and replace it with a substitute lens. Eyeglasses, contact lenses, or an intraocular lens implant then serves as a replacement lens.

Can Cataracts be Prevented?
No. Persons over age 60 are advised to visit an eye care professional every two years for early detection of cataracts.
