  2. Capsulotomy - Wikipedia

    en.wikipedia.org/wiki/Capsulotomy

    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]

    en.wikipedia.org/wiki/Cataract_surgery

    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 ...

    en.wikipedia.org/wiki/Intraocular_lens

    Posterior capsule opacification (PCO), often referred to as "after cataract", is the most common complication of cataract surgery. [ 28 ] In a small percentage of patients, posterior chamber intraocular lenses may form PCOs a few months after implantation.

  5. Cataract - Wikipedia

    en.wikipedia.org/wiki/Cataract

    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'.

  6. Nd:YAG laser - Wikipedia

    en.wikipedia.org/wiki/Nd:YAG_laser

    Slit lamp photograph of posterior capsular opacification visible a few months after implantation of intraocular lens in eye, seen on retroillumination. 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for peripheral iridotomy in patients with chronic [7] and acute angle-closure glaucoma, [8] where it has largely superseded ...

  7. Phacoemulsification - Wikipedia

    en.wikipedia.org/wiki/Phacoemulsification

    Complications after cataract surgery are relatively uncommon. Posterior vitreous detachment (PVD) may occur but does not directly threaten vision. [25] Some people develop a posterior capsular opacification (PCO), also called an after-cataract. This may compromise visual acuity, and can usually be safely and painlessly corrected using a laser.

  8. Capsule of lens - Wikipedia

    en.wikipedia.org/wiki/Capsule_of_lens

    In intra-capsular cataract extraction (ICCE), the whole lens including the anterior part of the capsule is removed. During more common extra capsular cataract surgery procedures like micro incision cataract surgery, phacoemulsification etc., the clouded lens is removed through an opening made in the anterior lens capsule. [ 23 ]

  9. Manual small incision cataract surgery - Wikipedia

    en.wikipedia.org/wiki/Manual_small_incision...

    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.
