What is cataract and when do you need to have a cataract operation?


Some people develop cataracts, which affect vision or lose vision over time. Most people start developing cataracts at the age of 40, but you may not notice symptoms until after the age of 60. Rarely, children are born with cataracts due to a congenital defect According to clevelandclinic, you are more likely to develop cataracts if you:


1: smoked.


2: You live in an area with air pollution.


3: You have a family history of cataracts.


Cataracts are 50% common among older adults over the age of 80.



Can you get cataracts in both eyes?

 

You can develop cataracts in both eyes, but one eye may be worse than the other or develop later.


The lens of your eye is made mostly of water and proteins. When the proteins break down over time, they hang around in your eye. These stuck proteins can make the lens cloudy, so it's hard to see clearly. This is a typical though unpleasant part of aging.


Certain things can speed up the formation of cataracts, such as:


1: diabetes.


2: Steroids, common medications for treating conditions such as arthritis and lupus.


3: Medications to treat a variety of mental illnesses such as schizophrenia and bipolar disorder.


4: Eye surgery or eye injuries.


5: Radiation therapy for the upper body.


6: Spending a lot of time in the sun without eye protection, such as sunglasses.


What are the symptoms of cataracts?



Cataracts are a stage of eye aging, and can cause:


1: Cloudy, hazy, hazy or hazy vision.


2: Sensitivity to bright sunlight, lights or headlights.


3: Glare (seeing a halo around lights), especially when driving at night with the headlights approaching.


4: Prescription changes in glasses, including sudden myopia.


5: double vision.


6: The need for brighter light for reading.


7: Difficulty seeing at night (weak night vision).


8: Changes in the way you see color.


Are the symptoms harmful?

 

Cataracts usually don't hurt, but they can cause discomfort by making your eyes more sensitive to light.


How is cataract diagnosed?

 

If you have symptoms of cataracts, see an ophthalmologist for a complete examination. Your doctor will need to dilate your pupil to see what's inside your eye. During this test, special drops dilate the pupil (the black part of the eye), and your doctor checks your eye health. For your doctor to see if you have cataracts or other problems and to see how much your vision is blocked.


If your cataract symptoms are mild, you may only need a new prescription for eyeglasses or contact lenses. Your cataracts usually worsen over time. Eventually, your doctor will likely recommend cataract surgery.


How is cataract removed?

 

During surgery, the surgeon removes the cloudy lens and replaces it with an artificial lens implant. The new lens is clear to fit your eye and customized to your visual needs.


The operation takes about an hour and is done with local anesthesia (medication to numb a specific area). Your doctor will use drops or a syringe to numb your eye. You will be awake, but you will not feel or see during the procedure.
