Cataracts 
Definition
A cataract is when your eye's natural lens becomes cloudy. Proteins in your lens break down and cause things to look blurry, hazy or less colorful.
Causes
an overproduction of oxidants, which are oxygen molecules that have been chemically altered due to normal daily life
-
-
certain diseases, such as diabetes
-
-
Treatment
phacoemulsification, involves the use of ultrasound waves to break the lens apart and remove the pieces.
Extracapsular surgery involves removing the cloudy part of the lens through a long incision in the cornea.
-
Pathophysiology
Compaction and stiffening of the central lens material (nuclear sclerosis) as new layers of cortical (outer lens) fibers continue to proliferate over time.
