Cataracts - Exams and Tests

Diagnosis of cataracts is based on a medical history and physical exam.

Often tests are used to:

  • Confirm the presence of a cataract.
  • Rule out other conditions that may be causing vision loss.

When you are deciding whether to have surgery, you may find it very helpful to evaluate the effect that vision loss from a cataract has on your life. Your doctor may ask you to complete a questionnaire regarding the effect of the cataract on your daily activities.

If you already have some vision loss that cannot be corrected by cataract surgery, your doctor may do a low-vision evaluation to help find ways for you to make the most of your remaining vision and to keep your quality of life.

Early detection

During routine eye exams, your eye doctor will look for early signs of vision problems, including cataracts.

Testing your child for cataracts may be needed if you think your child is having a vision problem.
