The protein molecule is arranged such that it is crystal clear thereby allowing light passing thorough to the retina
analogous to a film in a camera.
With age, the protein in the lens changes (becomes "denatured") and it becomes physically cloudy. This creates visual symptoms.
Some studies suggest that ultraviolet light is also associated with cataract formation. Medical problems such as diabetes
increase the rate of progression of cataracts. Many medications such as steroids
, etc do also contribute to an increased rate of cataract formation. Risk factors include genetics, smoking
, poor diet
, and heavy alcohol consumption
, and many others.
Initially when symptoms of cataract (such as blurred vision
, glare, difficulty with driving at night, etc) appear, one may able to improve vision with glasses
, improved lighting, and other visual aids
. An attempt to reduce the risk factors, some mentioned above is important.
If cataracts interfere with active daily living activities, and the quality of vision with correction is not satisfactory, after consultation with an ophthalmologist, one may consider cataract surgery
Except in certain situations, cataract surgery is elective, meaning that it is ultimately a decision made by the patient after considering pros/cons of cataract surgery.
