A cataract is simply a clouding of the lens usually brought on by age.  In order to see something, light rays pass through the pupil and focus through the lens onto the retina (a layer of light-sensitive cells at the back of the eye.)    The lens is made of mostly water and protein.  The protein is arranged in a precise way that keeps the lens clear.  Aging can cause some of the protein to clump together and start to cloud a portion of the lens.


Cataract is one of the most common causes of vision loss and develop gradually.  If you notice your sight becoming blurry or not as bright and colorful as before, schedule an appointment with your Eye MD.

Performing a complete eye exam is the only way your ophthalmologist can determine if your vision loss is a cataract or another problem. There are no medications or drops that will remove cataract, but it can be easily treated with surgery.  It’s not always necessary to remove the cataract immediately as long as it is not affecting your lifestyle.  Changing your eyeglass prescription may be enough for the present.  It is imperative your ophthalmologist monitor your vision regularly for changes.

When a cataract becomes bothersome and interferes with your daily activities, it may be time to consider surgery.  During the procedure, the eye’s cloudy lens will be removed and replaced with a clear artificial lens implant called an intraocular lens or IOL. Your ophthalmologist can discuss the surgery with you and answer any of your questions.
