Cataracts and Cataract Surgery
cataracts are mentioned, people often think of a film that
grows over their eyes, causing them to see double or blurred
images. The truth is though, that a cataract doesn't form
on that eye, but instead, inside the eye.
cataract is a clouding of the natural lens, the part responsible
for focusing light and producing a clear, sharp image. The
lens is contained within a sealed capsule and as we age, old
cells die and become trapped within this capsule, causing
the lens to cloud, making images look blurred and fuzzy.
For most people, cataracts are a natural result of aging.
In fact, cataracts are the leading cause of visual deterioration
in adults (55 years or older).
Eye injuries, certain medication and diseases such as diabetes
and alcoholism have also been known to cause cataracts. Some
of the first symptoms that cataract patients experience is
excessive glare, haloes around lights and increased sensitivity
Cataracts make driving at night very difficult. In fact,
any activity that requires good vision can be hampered or
severely limited by cataracts.
