Why Get Cataract Eye Surgery?
Cataracts. You may have been aware of them, but do you know anything regarding them? If not, you should, because cataracts can have an effect on anyone and it’s critical to educate your self concerning the eye health.
By definition, a cataract is a clouding of the lens in the eye which affects the vision. Cataracts are very common in older people, and by age eighty, over fifty percent of Americans either have a cataract or have had to go through cataract eye surgery. Though a cataract is not contagious, implying it can’t spread from eye to eye or person to person, they can impact both eye, and in most cases, both.
When an individual’s eyes are normal, environmental light is passed through the transparent lens of the eye in to the retina of the eye. As soon as the light touches the retina area, the light is afterwards translated in to nerve indicators that are transmitted to the brain. In order for this to occur, the lenses of the eyes need to be clear so that the light can pass through and the retina can interpret strong, sharp images to send to the brain. A cataract leads to cloudiness on the lens, which impedes the passing through of life and leaves you with blurry vision. Over time, the cloudy area in the lens may get larger, and the cataract may increase in size, resulting in poorer eyesight. Advanced lens cloudiness can affect your color perception as well.
There are a number of sorts of cataracts, which includes:
- A Secondary cataract, which is often come about after surgery for some different eye problem, like glaucoma. Cataracts are sometimes linked to steroid use.
- A Traumatic cataract, which can pop up after an eye injury. And by after, we mean anytime after, as cataracts caused by traumatic eye issues can appear years after the trauma has been dealt with properly.

In this particular case, the cataracts may be so small that they go completely undedetcted and it isn’t until much later in life when the child realized that how they’ve been viewing the world is much different from what others are seeing. do not affect vision. If they do, the lenses may need to be removed.
- And finally, there is such a thing as a Radiation cataract, which is caused by the exposure to some types of radiation.
What causes cataracts?
The lens of the eye is situated behind the iris and pupil. In a functioning eye, the lens focuses light on to the retina, where the light is then recorded as an image. It’s water and protien that make up the majority of the lens of the eye. As we progress in age, these proteins may clump together and cloud the lens.
There are other causes of cataracts, but old age is most common.
