Understanding the Different Types of Cataracts

Cataracts are a common age-related condition that cloud the natural lens of the eye, causing blurred vision and difficulty with tasks like reading or driving. While many people associate cataracts with getting older, they can also result from injury, medication use, or underlying health conditions. At Eye Associates, our eye doctors provide detailed evaluations and treatment plans for patients in San Antonio, Boerne, and Kerrville, TX. Understanding the different types of cataracts can help guide decisions about eye care and when to consider surgery.

Nuclear Cataracts

Nuclear cataracts form in the center of the lens and typically develop slowly over time. Patients may initially notice a temporary improvement in close-up vision, but this is often followed by gradual yellowing or browning of the lens. This discoloration can make it harder to distinguish colors and may reduce night vision. Nuclear cataracts are the most common type and are frequently addressed through cataract surgery once they begin to interfere with daily life.

Cortical Cataracts

Cortical cataracts begin at the outer edges of the lens and develop inward in a spoke-like pattern. They often cause problems with glare and halos, especially when driving at night. This type of cataract can also lead to blurred or distorted vision as the opacities progress toward the center. Regular eye exams help our clinic monitor cortical cataracts and determine the appropriate time for treatment.

Posterior Subcapsular Cataracts

This type of cataract forms near the back of the lens, directly in the path of light entering the eye. Posterior subcapsular cataracts can develop quickly and are more likely to affect reading vision and cause sensitivity to bright lights. They are often seen in people with diabetes or those taking steroid medications. Early detection and management are important, and surgery is often recommended sooner than with other types.

Congenital and Secondary Cataracts

Congenital cataracts are present at birth or develop during childhood and may be due to genetic factors or infections. Secondary cataracts can develop after eye surgery, trauma, or as a result of certain diseases. Both types require close monitoring by an ophthalmologist to determine the best approach for maintaining vision. In some cases, surgical intervention is necessary early in life.

When to Consider Cataract Surgery

When cataracts begin to interfere with everyday tasks, surgery becomes a safe and effective solution. Cataract surgery involves replacing the clouded lens with a clear artificial one to restore vision.
