In the early days of cataract surgery, the only thing that surgeons could do was remove the cloudy lens. Without a lens inside their eye, patients had to wear very thick âCoke bottleâ glasses to see.
During cataract surgery, a patient's cloudy natural cataract lens is removed and replaced with a synthetic lens to restore the lens's transparency. Following surgical removal of the natural lens, an artificial intraocular lens implant is inserted (eye surgeons say that the lens is implanted). As a physiological change expected after cataract surgery, the posterior capsular cells undergo hyperplasia and cellular migration, showing up as a thickening, opacification and clouding of the posterior lens capsule (which is left behind when the cataract was removed, for placement of the IOL).
