What is cataract? cataract treatment, types, symptoms, causes of cataract


Cataract is a normal result of aging. As the age approaches 60, the opacity of the eye lens, also known as cataract, increases. Frequent change of eyeglasses is one of the alarming symptoms for cataract.

Definition of cataract:

Cataract is the turbidity of the lens of the eye that lies behind the pupil, which is responsible for redirecting light to the retina.

Cataract types:

1- Nuclear hardening:

It is the most common type of cataract targeting the center of the lens. It occurs as a result of aging, as the lens nucleus intensifies, and causes poor vision and various visual problems.

2- Cortical Cataract:

One of the most prominent symptoms of this type is the occurrence of flare and dispersion of light at night and occurs as a result of a change in the water content that surrounds the lens causing cracks.

3- The posterior capsular cataract:

This type results in blackout in the back of the lens, as the light is concentrated in the back of it, so the symptoms may vary from person to person because of the size change.

4- Congenital cataracts

Which are present at birth or form during a baby’s first year, are less common than age-related cataracts.

5- Secondary cataracts

Which are caused by disease or medications. Diseases that are linked with the development of cataracts include glaucoma and diabetes. The use of the steroid prednisone and other medications can sometimes lead to cataracts.

6- Traumatic cataracts

Which are developed after an injury to the eye, but it can take several years for this to happen.

Which can form after a person undergoes radiation treatment for cancer.
