Introduction.
Cataract is an eye disease in which the natural lens of the eye becomes cloudy or the transparency of your lens is either greatly reduced or in some cases completely lost as a result of tissue breakdown and protein clumping.
Cataracts cloud the eye's natural lens,
which is located behind the iris and pupil, and this clouding blurs vision, making it difficult to see clearly and perform daily tasks. It becomes difficult to do
In a condition in which the lens becomes cloudy, symptoms include blurred vision and cloudiness.
It is also a sign that a scene or more than one scene starts to look double
Difficulty seeing at night can also be experienced. Untreated cataracts can lead to blindness.
As mentioned earlier, a cataract is a cloud over the lens of the eye.
Before a cataract, this lens or this area is clear and transparent which must be called a great gift from God
But as the cataract deepens, it forms a wall between the lens of the eye and the retina, and light rays can no longer pass through the lens and reach the retina.
The retina is a tissue lining that is very sensitive to light. It has also been reported that it is located at the back of the eye.
This cloud of cataracts is formed when some of the proteins that make up the lens of the eye begin to change their structure, and when this process begins, they stand up and obstruct the path of vision.
Another cause of cataracts is a buildup of protein in the eye that prevents the lens from sending clear images to the retina.
Now let's see what role the retina plays in the eye. The retina has two special functions. Number one, it converts light coming through the lens into signals. Number two, it sends signals to the optic nerve, which carries them to the brain.
In cataracts, this lens becomes gradually cloudy when light passes through the lens so cannot be fully focused on the retina. Just like if the sky is covered with clouds, the light of the sun or the moon does not reach the earth fully, that is the reason why the patient of cataract sees everything dimly.
Most common types of cataracts.
1. Nuclear
2. Cortical
3. Posterior subcapsular
4. anterior subcapsular
5. posterior polar
6. traumatic
7. congenital
8. polychromatic
CAUSES
· Cataracts are often seen in diabetic patients due to secondary medical conditions. A particular type of cataract occurs in diabetic patients. In addition, high blood pressure can also cause cataracts.
· Obesity, high cholesterol level drug use, and long-term use of steroid corticosteroids are also causes.
· Cataracts can also be caused by vitamin B or vitamin C deficiency and ultraviolet radiation
· With aging or injury, the proteins and fibers in the lens begin to break down, causing cataracts.
· Hereditary diseases passed down from parents' past surgeries or other health problems are all among the causes of cataracts.
· Cataracts occur when protein forms a layer on the lens of the eye. This natural process continues with age, leading to a cloudiness that turns into blindness.
· Being over 50 years of age, smoking, drinking alcohol, or going out in the sun without sunglasses are all possible causes.
SYMPTOMS OF CATARACT?
Ø Color vision becomes blurred.
Ø Headlight lamps or sunlight seem too bright
Ø A situation appears around the light
Ø Can't see well at night
ØHave trouble focusing on faces
Ø Also has difficulty recognizing other objects at a distance
Ø Can't drive at night
Ø Having to change the numbers of your glasses or contact lenses.
Treatment
Medical procedure is the best way to dispose of a waterfall
Waterfall medical procedure is the best way to eliminate waterfalls and reestablish your reasonable vision. During a cataract medical procedure, an ophthalmologist eliminates your obfuscated regular focal point and replaces it with an intraocular focal point (IOL). An IOL is a counterfeit focal point that for all time stays in your eye
