Before you can get
custom cataract surgery to improve your vision, you have to have a better understanding of the
different kinds of cataracts. Keep reading to learn more about cataracts:
A Subcapsular Cataract
This kind of cataract develops at the back of the lens. Subcapsular cataracts
usually start off as a small dot and gets in the way of light as it travels
toward the retina. Because of its location, a subcapsular cataract typically
affects one's ability to read. It can also make it more difficult
to see in bright lights. People with these kinds of cataracts might also
start to see halos around lights at night. If you have any of these issues,
you should schedule an appointment with your eye doctor in Chicago to
see if you need cataract surgery.
A Nuclear Cataract
This kind of cataract develops in the center of the eye. Nuclear cataracts
are usually a result of the natural aging process. When this kind of cataract
first develops, it might make a person more nearsighted, but some people
actually experience an improvement in their reading vision. A nuclear
cataract can eventually turn the lens yellow or brown. Once it advances,
it might make it more difficult to differentiate between shades of color.
A Cortical Cataract
Cortical cataracts start at the outer edge of the lens and move toward
the center. Cortical cataracts worsen slowly, but when they finally reach
the center, they can hinder the way light hits the lens. People who have
this kind of cataract usually have difficulty seeing when there is a glare.
A Congenital Cataract
Although it is very rare, some people are born with congenital cataracts.
They develop when a mother has an infection while pregnant or as a result
of other conditions like myotonic dystrophy, galactosemia, Lowe's
syndrome, or rubella. If you suspect that you have any kind of cataract,
it is important to visit your eye doctor to get the treatment you need.
