Subcapsular Cataract Symptoms that Shouldn't Be Ignored
 A subcapsular cataract is not considered to be a "true cataract," because it occurs behind the lens capsule, but this cataract type can still cause many vision problems. Sometimes called a "secondary cataract" or an "after cataract," a subcapsular cataract can develop after surgery for a lens cataract. In some cases, an after-cataract may develop years after surgery. Subcapsular cataracts have also been linked to aging, steroid use, diabetes, and other health conditions.
The symptoms of a subcapsular cataract arise because of the way light is obstructed from passing to the retina and may causes problems like:
- Difficulty seeing in glaring conditions, especially when driving at night
- Reduced vision in bright lights
- Decreased close-up vision capabilities (farsightedness)
- The appearance of halos around lights, especially at night
- Rapidly progressing vision changes
Not all cases require immediate and invasive procedure to relieve symptoms. For instance, mild symptoms may be corrected with simple changes like a different strength of eyeglass prescription. However, if symptoms continue to progress and begin to affect your quality of life, more intensive measures like surgery could be necessary. Subcapsular cataract surgery, which is often very successful, is an outpatient procedure that generally last less than an hour. Many patients return to their normal activities within a few short days.
