Cataracts are a common eye condition affecting nearly 22 million Americans
age 40 and over.
Cataracts are often mistaken as a growth or film on the eye, but in reality they
are the result of clouding on the focusing lens of the eye, which is located
behind the pupil.
Cataracts occur when protein builds up on the lens of the eye. Mild clouding
caused by the protein may not affect vision, but more serious clouding
can affect one’s ability to perform normal daily tasks such as reading,
working around the home, seeing street sights and driving at night.
Who gets cataracts?
Although cataracts are often related to aging, they can also affect young
people. There are three primary causes of cataracts other than age. These include:
Congenital cataracts — Developmental or congenital cataracts can develop even in infants or children.
This type of cataract is typically associated with genetics or associated
with birth defects, though in some rare cases, there is no clear cause
of the cataracts.
Cataracts from disease or medication —In some cases, cataracts may be caused by disease, such as diabetes, or
a previous eye surgery. Excessive use of steroid medications to treat
other medical conditions may also lead to the development of cataracts.
Traumatic cataracts —A traumatic injury to the eye may also cause cataracts to develop. In some
cases, these cataracts will develop soon after the injury, while in other
cases they may take months or even years to develop.
What are the symptoms of cataracts?
As cataracts develop, they can affect your ability to see in several ways.
Common symptoms of cataracts include:
• Difficulty seeing street signs, curbs and freeway exits
• Difficulty seeing traffic lights, or seeing a halo or glare around lights
• Difficulty focusing while watching TV or movies
• Difficulty seeing the faces clearly

How are cataracts treated?
Cataracts cannot be removed, nor can the progression of cataracts be arrested
or reversed. Once cataracts begin to develop, there is no way to make
the lens clear again. In order to restore vision that has been lost due
to cataracts, the clouded lens must be removed and replaced with an artificial
Key-Whitman offers patients several
cataract treatment options for lens replacement other than the standard monofocal lens, which corrects
vision at a single distance. Multifocal lenses and accommodative lenses
may provide a wider range of vision for near, far or intermediate following surgery.
Though only your eye doctor can diagnose cataracts, you may notice
