out If You Have One of These Common Conditions Above
is a cloudy eye lens, not a film growth over the eyes. Having
a cataract is like looking through an opaque window. Thelens
in the eye is normally very clear and changes in shape to focus light
to a point in the back of your eye. When it becomes clouded up, light
cannot easily pierce through the lens, so the image your eye absorbs
your mouse over the photo to see through the eyes with cataracts
is the most common cause of this disease. It begins most often after
the age of 55, and by 75 years, almost one out of four people have
a cataract. The lens is held in place by a thin bag inside your eye.
As people age, the old cells of the lens bag die and build up
inside it, clouding the lens. This happens very gradual, but certain
factors may induce the process, such as drugs and alcohol, an incident
to the eye, poor eating habits, inheritance, and congenital problems.
Excess sunlight to the eyes and smoking have been known to put you
more at risk in developing a cataract.
and foggy vision, esp. at old age
absolutely no way to prevent its development because cataracts
occur naturally as aging begins. Wearing sunglasses that protect you
from ultraviolet rays, not smoking, and eating healthy are measures
you should follow to postpone the growth of cataracts.
who have cataracts, however, normally use glasses
in its early stages, when the cloudiness is not as obscure. When the
cataract becomes intolerable to the patient, surgery is the best option
to replace the clouded lens with an implant lens, called an
intraocular lens (IOL). Obviously, these implanted lens cannot focus,
but they are made so that the patient can choose what type of vision
he/she wants-close, far, or both. The most common kind is farsight.
The patient will then have to use reading glasses to see clearly up
close. Another method the patient can choose is monovision. Monovision
describes correcting one eye for far distance vision and the other
eye for close up vision, so that glasses or contacts is not necessary.
The person will adapt to this method after a while.
for this surgery begins when the edges of the cornea is sliced
open to allow a very narrow instrument to be inserted into the lens,
where ultrasound shatters the lens and gets sucked out, through a
technique called phacoemulsification. The implant lens, made of plastic
or silicone, is then inserted in place of the old one and the cornea
flipped back into shape, where it self heals without stitches because
of the the suction involved.
