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 ...
Sheep eye lens capsule with ligaments attached. The capsule is lifting off the lens showing cell fiber ends beneath. Microscope image of lens capsule in relation to lens cell types. The lens capsule is a component of the globe of the eye. [1] It is a clear elastic basement membrane similar in composition to other basement membranes in the body.
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]
Posterior capsule opacification reaches an incidence of about 28.4% by five years, and is influenced by many factors, including age, IOL lens material, lens design, quantity of residual lens cortex, history of ocular inflammation, and size of capsulorhexis.
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. [28]
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.
Sheep lens capsule removed. Decapsulation leads to a nearly formless blob. Eye lens micrographs and diagram of growth region of the capsule. The lens capsule is a smooth, transparent basement membrane that completely surrounds the lens. The capsule is elastic and its main structural component is collagen.
