How Cataracts Develop: A Clinical Analysis

Cataracts develop when the normally clear lens inside your eye gradually becomes cloudy. The lens focuses light onto the retina, helping create a clear image. With age, changes within the lens can cause its proteins to break down and clump together. These changes can interfere with light transmission and may eventually affect the clarity, color, and sharpness of your vision.

At Schwartz Laser Eye Center, board-certified ophthalmologists Dr. Jay L. Schwartz and Dr. Orry Birdsong work alongside skilled optometrists to provide comprehensive cataract care in Scottsdale, Glendale, and Mesa, AZ.

What Happens Inside the Lens as Cataracts Form?

Your natural lens contains proteins that help keep it clear. As the lens ages, these proteins can change and clump together, scattering light and creating the cloudiness associated with age-related cataracts.

These changes can begin around age 40, although noticeable cataract symptoms may not appear for years.

What Factors Are Associated With Cataract Development?

Several biological and environmental factors may influence the development if cataract. These include:

• Aging: Natural changes in the lens can contribute to cataract formation over time.
• Diabetes: May be associated with an increased risk of developing cataracts.
• Family history: A family history of cataracts may influence the development of cataracts.
• Certain medications: Some medications may contribute to changes within the eye’s natural lens.
• Previous eye injury or surgery: Changes to the eye following an injury or previous procedure may be associated with cataract formation.
• Smoking: Smoking is another factor associated with cataract development.
• Ultraviolet exposure: Prolonged exposure to ultraviolet light may contribute to changes within the lens.

What Are the Symptoms of Cataracts?

As a cataract progresses, you may notice:

• Cloudy or blurry vision
• Faded colors
• Increased sensitivity to bright light
• Difficulty seeing at night
• Frequent changes to your glasses prescription

How Are Cataracts Treated?

When cataracts begin to interfere with your vision, cataract surgery may be considered. During the procedure, the cloudy natural lens is replaced with an intraocular lens (IOL). Schwartz Laser Eye Center offers cataract care with advanced lens options, including the AcrySof® Toric IOL for individuals with astigmatism.
