A cataract is a clouding of the eye’s natural lens, which lies behind the iris and the pupil.  The lens works much like a camera lens, focusing light onto the retina at the back of the eye.  The lens also adjusts the eye’s focus, letting us see things clearly both up close and far away.

 

The lens is mostly made of water and protein.  The protein is arranged in a precise way that keeps the lens clear and allows light to pass through it.  As we age, some of the protein may clump together and start to cloud a small area of the lens.  This is a cataract, and over time, it may grow larger and cloud more of the lens, making it harder to see. Most cataracts are age-related.  However, cataracts can also be present at birth or occur at any age. Cataracts can also be caused by diseases such as diabetes or can occur as the result of long-term use of certain medications, such as steroids.

Symptoms of Cataracts

Decreased vision is the most common symptom of cataracts.  If you have other abnormal vision-related symptoms, cataracts may be the cause.

Cataract Surgery

Modern cataract surgery is a treatment option for many patients.  Review the procedure and its normal recovery period.

Premium Intraocular Lenses

If you need cataract surgery, you may have the option of getting new presbyopia-correcting IOLs that potentially can restore a full range of vision without eyeglasses.
