What Is A Cataract?
A cataract is a clouding of the normally clear lens of the eye. The lens focuses light rays on the retina at the back of the eye to produce a sharp image of what we see. When the lens becomes cloudy, the light rays cannot easily pass through it, and the image becomes blurry.
Cataracts usually develop as part of the aging process, but can also come from:
- Eye injuries
- Certain diseases
- Genetic inheritance
How Can A Cataract Be Treated?
The cataract may need no treatment at all if the vision is only a little blurry. A change in your eyeglass prescription may improve vision for a while. There are no medications, eye drops, exercises or glasses that will cause cataracts to disappear once they have formed. When you are not able to see well enough to do the things you like to do, cataract surgery is the only way to improve your vision. In cataract surgery, the cloudy lens is removed from the eye. In most cases, the focusing power of the natural lens is restored by replacing it with a permanent intraocular lens implant. Over 95% of cataract surgeries improve vision.
