Diagnosis & Treatment of Cataracts
A cataract is a common condition that causes a clouding of the eye’s natural lens, and affects millions of people each year, including more than half of all Americans over the age of 65. Cloudiness develops as a result of a buildup of protein in the lens
Cataracts cause a progressive, painless loss of vision. The lens clouds naturally as we age, causing people over the age of 65 to see a gradual reduction of vision. However, cataracts are not considered part of the natural aging process and are a serious condition that requires prompt medical attention. The exact cause of cataracts is unknown, although it may be a result of injury, certain medications, illnesses (such as diabetes), prolonged exposure to ultraviolet light and smoking. Symptoms may include:
- Blurred/hazy vision
- Spots in front of the eye(s)
- Sensitivity to glare
- A feeling of “film” over the eye(s)
Your doctor may perform a series of tests in order to diagnose a cataract. A dilated eye exam will be performed to test the vision and to examine the condition of the lens and other parts of the eye. Your doctor may also perform tonometry, a procedure that measures the pressure in the eye.
Vision with cataract
After the cloudy lens has been removed, a new artificial lens, or IOL, is implanted in the eye. With the recent advance of foldable IOLs (intraocular lenses), artificial lenses can be implanted through the same small incision from the phaco procedure.
Risks and Complications
If left untreated, cataracts will worsen over time and may lead to permanent vision loss or even blindness. It is important to see your eye doctor regularly in order to detect cataracts as early as possible and to plan an effective treatment method.
Although cataract surgery is considered safe, there are certain risks associated with any surgery. Some of these risks may include pain, infection, swelling and bleeding. Most patients undergo this procedure without any complications.
