Some people develop posterior capsular opacification (PCO), also called an "after-cataract". After cataract surgery, posterior capsular cells usually undergo hyperplasia and cellular migration as part of a physiological change, showing up as a thickening, opacification, and clouding of the posterior lens capsule, which is left behind after the ...
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'.
Months or years after the cataract operation, the remaining posterior lens capsule can become opaque and vision will be reduced in about 20–25% of eyes. [4] This is known as posterior capsule opacification (PCO). PCO is best treated by posterior capsulotomy using YAG laser. [4]
A posterior capsular opacity (PCO) around a posterior chamber IOL (as seen on retroillumination in a slit lamp) Posterior capsule opacification (PCO), often referred to as "after cataract", is the most common complication of cataract surgery.
Posterior capsular rupture, a tear in the posterior capsule of the natural lens, is the most-common complication during cataract surgery. [8] Posterior capsule rupture can cause lens fragments to be retained, corneal oedema, and cystoid macular oedema; it is also associated with increased risk of endophthalmitis and retinal detachment.

Mittendorf's dot: A small circular opacity on the posterior lens capsule, which represents the site of attachment of the hyaloid artery before it subsequently regressed. [8] Bergmeister's papilla: A tuft of fibrous tissue at the optic disc, which represents a remnant of the sheath associated with the hyaloid artery before it subsequently regressed.

Nd:YAG lasers are used in ophthalmology to correct posterior capsular opacification, [6] after cataract surgery, for peripheral iridotomy in patients with chronic [7] and acute angle-closure glaucoma, [8] where it has largely superseded ...
