A cataract is a clouding of the eye’s natural lens. The lens is normally completely clear.
Cataracts are formed when the natural lens in our eyes becomes cloudy and opaque due to various possible factors and the lens slowly becomes discolored (yellow or white). Because the lens focuses light inside the eye, vision slowly becomes blurry as a cataract form.
As you age, the lenses in your eyes become less flexible, less transparent, and thicker.
Most cataracts develop slowly and don't disturb your eyesight early on. But as time goes by, cataracts begin to eventually interfere with your vision.
Causes of cataract
The main cause of cataracts is aging. Other factors that put you at risk of developing a cataract include:
Diabetes and other metabolic diseases
Long-term use of diuretics and tranquilizers
Previous eye surgery
Excessive exposure to sunlight
Living at a high altitude
Chronic eye inflammation
In addition to advancing age, other cataract causes include:
Long-term exposure to ultraviolet light
Long-term and short-term exposure to radiation
Eye trauma or eye injury
Congenital conditions (present at birth, passed on through DNA)
Prolonged use of corticosteroids
How to get rid of it using "Laser Cataract Surgery"
A cataract occurs when the eye’s natural lens becomes cloudy. During traditional cataract surgery, cataract surgeons use a small blade to enter the front of the eye and another instrument to make a circular incision on the lens capsule to reach the cataract. Ultrasound waves break the cataract into tiny pieces, which are then removed.
The new artificial lens is inserted to replace the cloudy natural lens. In laser cataract surgery, a laser is used to make the incision and lens opening. “It creates a more reliable, repeatable, precise incision than a surgeon can do by hand. Even a very good surgeon can’t make a perfect circle as precisely as a laser can.”
“When we see people who need cataract surgery, we determine if they would be a candidate for a premium lens as well as the use of the laser, and educate them about the benefits. It is up to the patient to decide if they want traditional surgery or laser cataract surgery."
