When the lens of your eye becomes cloudy because of aging or other factors, you have a cataract. This change interferes with the passage of light through the lens to the retina (light-sensitive tissue at the back of the eye). As a result, your vision becomes blurry. Fortunately, treatment of cataracts can improve your vision and your quality of life.

Your eye lens consists mostly of protein and water. As you age, the protein can clump in a small area. Over time, the clump grows larger and causes your vision to become worse. Cataracts may begin when you are in your 40s or 50s, but they typically do not cause symptoms at first. According to the National Eye Institute, more than 50 percent of people in the U.S. have a cataract by age 80.

Cataracts can develop in one or both eyes. Symptoms include:

  • Cloudy vision
  • Glare or halo around objects
  • Double vision
  • Reduced night vision
  • Decreased color intensity
  • Yellowish or brownish tint to vision

Apart from aging, factors such as eye injury, diabetes, surgery for other eye problems and radiation exposure can contribute to cataracts. Smoking and excessive sun exposure are also risk factors.

In the early stages of cataracts, eyeglasses or contact lenses might be enough to address your symptoms. In advanced cases, vision loss can make it difficult to perform daily activities such as reading and driving. In fact, cataracts can block nearly all of your vision, allowing you to see only light and dark.

Having cataracts does not mean you have to live with reduced vision. Cataracts are highly treatable. We provide treatment to help you regain your eyesight so that you can participate fully in your work, hobbies and other daily activities.

Regular comprehensive eye examinations can identify cataracts and determine whether your vision is decreasing. We work with you to determine whether the time is right to remove cataracts through surgery. Our highly experienced ophthalmologists provide personalized treatment based on your specific needs.

Our experts offer the most advanced diagnosis and treatment of cataracts. As part of the Indiana University School of Medicine, the Eugene and Marilyn Glick Eye Institute brings together an international team of world-class researchers in the fields of eye and vision research. Additionally, our residency and fellowship training programs ensure that the next generation of ophthalmologists is well equipped to deliver excellent care.
