Cataract is an opacity of the Lens of the Eye that can lead to a change in the vision, in almost all cases, a decreased vision in the eye affected.

Light is unable to pass through the lens as well as an increased difficulty focusing on the desire object.

The retina in the back of the eye must work harder to visualize the object.

Potential Causes of Cataracts:

–  Aging
–  Trauma
–  Congenital causes
–  Excessive sun exposure
–  Medications
–  Skin diseases
–  Radiation
–  Infections
–  Other eye diseases
–  Others

Likely Symptoms of Cataracts

–  Cloudy or Opate lens
–  Difficulty reading
–  Difficulty driving
–  Changes in seeing colors
–  Light glares
–  Difficulty with changing contrasts
–  Difficulty with bright lights


1.)  Hard or Soft

2.)  Complete or Partial

3.)  Stationary or Progressive

Different Types of Cataracts

1.)  Nuclear Sclerosis

–  Most Common type
–  Involves the central portion of the lens
–  Becomes Hard
–  Can turn brown over time
–  Advance stages can be called – Brunescent Cataract
–  Problems with nearsightedness and distances
–  Reading is affected minimally

2.)  Cortical

–  Opacifications are found in the cortex of the lens
–  This is the outer layer
–  Appearance of white spokes
–  Problems with glare and light at night

3.)  Posterior Subcapsular

–  Opacifications are found at the back of the lens
–  These are adjacent to the capsule of the lens
–  Light symptoms and adjusting to size of objects.

–  Surgery can place injections, or lens insertion, or slicing away tissue affected.
