Posterior capsular opacification, also known as after-cataract, is a condition in which months or years after successful cataract surgery, vision deteriorates or problems with glare and light scattering recur, usually due to thickening of the back or posterior capsule surrounding the implanted lens, so-called 'posterior lens capsule opacification'.
Cataract surgery is the removal of the natural lens of the eye that has developed a cataract, an opaque or cloudy area. [3] Over time, metabolic changes of the crystalline lens fibres lead to the development of a cataract, causing impairment or loss of vision.

Cataracts are the leading cause of child and adult blindness that doubles in prevalence with every ten years after the age of 40. [57] Consequently, today cataracts are more common among adults than in children. [56] That is, people face higher chances of developing cataracts as they age.
A cataract is an opacity that develops in the crystalline lens of the eye. [9] The word cataract literally means, "curtain of water" or "waterfall" as rapidly running water turns white, so the term may have been used metaphorically to describe the similar appearance between mature ocular opacities and water fall.
The other common galactose metabolism defect is a defect in galactose-1-phosphate uridylyltransferase, an autosomal recessive disorder, which also causes a buildup of galactitol as a result of increased concentrations of galactose-1-phosphate and galactose. This disorder leads to cataracts caused by galactitol buildup.

Glassblower's cataracts are due to chronic exposure to infrared radiation emitted due to the extreme heating of glass or molten metal. The infrared radiation is absorbed by the iris and lens of the eye. This causes cataracts after decades of exposure. [2] This condition may be prevented by wearing protective glasses while practicing these ...
