Types of Cataracts

Beverly Hills, Westlake Village, and Surrounding Areas of Los Angeles, California

Not all cataracts are the same. Different types of cataracts will have different effects on your vision. Generally speaking, cataracts are classified based on their location in your eye’s lens, and how they first developed (i.e. their origin).

If you are experiencing symptoms of cataracts, call us today at (888) 339-8143 to schedule a consultation with our experienced Los Angeles cataract surgeon Dr. Rajesh Khanna. We will diagnose the exact type of cataract you have, and explain the treatment process with you in detail.


Cataract Types Based on Location

Certain types of cataracts are classified based on where the clouding is located in your lens, such as:

  • Nuclear sclerotic – The most common age-related cataract. Causes a hardening of the central portion of your lens (the nucleus), and a yellow cloudiness. Produces gradual vision deterioration.
  • Posterior subcapsular – Occurs on the back of your lens, below the capsular bag that encases the lens. Results in blurry near vision, glare and halos at night, and light sensitivity. This cataract is most common in patients who have taken steroids for a prolonged period of time, or suffer from diabetes.
  • Cortical – Clouds the side (periphery) of your lens, called the cortex. These cataracts tend to look like wheel spokes that point inward toward the nucleus of the lens, causing light to scatter.

Cataract Types Based on Origin

Cataracts can also be classified by origin, based on how they developed. Examples of these cataract types include:

  • Age-related cataracts – Cataracts that develop due to the natural aging process. Most people experience age-related cataracts in their 60s or 70s, though they can potentially develop as early as your 40s.
  • Traumatic cataract – If your eye has suffered an injury, cataracts can develop either immediately or years later. The two most common causes of traumatic cataracts are blunt trauma to the eye, and chemical exposure.
  • Secondary cataract – If you have undergone eye surgery to treat a retinal problem, or a disease like glaucoma, you may be more prone to developing secondary cataracts. Steroid users and diabetics are also at a higher risk of secondary cataracts.
  • Congenital cataract – In rare cases, children can be born with cataracts. Mild congenital cataracts should not substantially affect vision, but in certain cases, more severe congenital cataracts must be removed in order to prevent amblyopia (lazy eye) or strabismus (cross eyes).
