Cataracts are a common age-related eye problem, causing cloudy or blurry vision, sensitivity to glare, and poor night vision. Cataract surgery is needed only when cataracts affect your vision so much that you can’t do the things you need to do in daily life.

Diabetic Eye Disease

Diabetic eye disease is a group of eye problems that can be caused by diabetes, including diabetic retinopathy [REH-tin-AH-puh-THEE], macular edema [MAH-kyoo-LUHR uh-DEE-muh], cataracts [KAT-uh-rakts], and glaucoma [glaw-KO-muh]. These conditions can cause vision problems or blindness, so it’s important to keep your diabetes under control and get regular eye exams to look for problems.


Glaucoma [glaw-KOH-muh] is a group of diseases that affect that optic nerve in the eye. If it isn’t caught and treated early, glaucoma can cause vision loss or blindness.

Loss of Vision

Vision loss is when you lose all or part of your ability to see. Vision loss can be caused by several conditions, including macular degeneration, glaucoma, cataracts, and diabetes.

Macular Degeneration

Macular degeneration is vision loss that occurs when the macula, which is the part of the eye that is used to see objects sharply and clearly, is destroyed. Macular degeneration is most common in people over the age of 60.

Refractive Errors

Refractive [ri-FRAK-tiv] errors occur happen when your eyes are shaped in a way that makes it hard for them to focus. Glasses, contact lenses, and laser surgery can help with refractive errors.
