All Cataracts are Not Created Equal

Cataracts represent one of the most prevalent eye conditions among older adults. The condition is characterized by the clouding of the natural lens of one or both eyes. As changes progress on the lens, light is prevented from passing through to the retina. As a result, vision worsens over time. The symptoms of cataracts develop gradually, beginning with signs such as colors appearing less vibrant and progressing to severely clouded vision. Fortunately, vision can be restored by replacing the affected lens with a new, clear intraocular lens.

The treatment for cataracts is consistent among patients, though the type of cataracts may differ from one person to another. Here, we discuss the three common types of cataracts.

Nuclear Sclerotic Cataracts

This most common type of age-related cataract develops deep in the nucleus, or central part, of the eye’s lens. The affected lens gradually hardens and turns yellowish or brown. Nuclear sclerotic cataracts usually develop over several years. They can significantly impact vision.

Cortical Cataracts

A cortical cataract first develops at the cortex, or the outer edge of the eye’s lens. Rather than turning the lens yellow or brown, cortical cataracts develop as white triangles that progressively spread inward from the edges of the lens. Because of their shape, cortical cataracts scatter light, which affects near and distance vision by causing abnormalities such as:

  • Haziness
  • Glare around light sources
  • Contrast problems that make colors all look similar
  • Depth perception issues

Posterior Subcapsular Cataracts

This type of cataract develops on the back surface of the lens rather than the front or side. Posterior Subcapsular cataracts also form inside the capsule that holds the lens, directly obstructing light as it passes through the front of the eye. Due to the location of this type of cataract, the condition may affect vision more quickly than other types. A person with posterior subcapsular cataracts may experience halos or glare around light sources and may have an increasingly more difficult time reading and performing near-vision tasks.
