Eye health guide Cataracts are cloudy areas that develop within the eye lens. A healthy lens is clear like a camera's, and light has no problem passing through it to the retina at the back where images are processed. When you have a cataract, the light can't get through as easily and, as a result, you can't see as well. Cataracts often form slowly, and they don't cause symptoms like pain, redness, or tearing in the eye. Some stay small and don't affect your eyesight.

Results Cataract surgery successfully restores vision in the majority of people who have the procedure. People who've had cataract surgery may develop a secondary cataract. The medical term for this common complication is known as posterior capsule opacification (PCO). This happens when the back of the lens capsule — the part of the lens that wasn't removed during surgery and that now supports the lens implant — becomes cloudy and impairs your vision.

Overview Cataract types include: Cataracts that affect the center of the lens (nuclear cataracts). A nuclear cataract may at first cause you to become more nearsighted or even experience a temporary improvement in your reading vision. But with time, the lens gradually turns more densely yellow and further clouds your vision.ome cataracts are related to inherited genetic disorders that cause other health problems and increase your risk of cataracts. Cataracts can also be caused by other eye conditions, medical conditions such as diabetes, trauma or past eye surgery. Long-term use of steroid medications, too, can cause cataracts to develop.

In contrast to nuclear cataracts, cortical cataracts are associated with the local disruption of the structure of mature fiber cells. Once membrane integrity is compromised, essential metabolites are lost from the affected cells. This loss leads to extensive protein oxidation and precipitation.
