The majority of people over the age of 65 suffer to some degree from lens opacification. The causes of the cataract are not fully understood.

Various factors such as familial tendency, diabetes, eye inflammation, cortisone or eye surgery and injuries favor its development.
Therapy

Finally, cataract surgery is the only measure that effectively defeats the cataract. The cloudy lens material is removed via a small 2-3 mm wide incision in the cornea and then a clear lens made of plastic is used. Most patients notice correction of vision immediately after surgery. For some, it may take a few days for the expected improvement to occur. The surgery is usually done on an outpatient basis and you can go home the same day.
