  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]

  3. Cataract surgery - Wikipedia

    en.wikipedia.org/wiki/Cataract_surgery

    Cataract surgery may be performed to correct vision problems on both eyes. If both eyes are suitable, people are usually advised to consider monovision. This procedure involves inserting an IOL providing near vision into one eye, while using one that provides distance vision for the other eye.

  4. 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'.

  5. Corrective lens - Wikipedia

    en.wikipedia.org/wiki/Corrective_lens

    A typical application of such a lens is to refocus the correction allowing clear vision at any distance. Unlike with bifocals, near-vision correction is achieved over the entire field of view, in any direction. Switching between distance and near vision is accomplished by re-adjusting the lens, instead of by tilting and/or rotating the head.

  6. Phakic intraocular lens - Wikipedia

    en.wikipedia.org/wiki/Phakic_intraocular_lens

    A phakic intraocular lens (PIOL) is an intraocular lens that is implanted surgically into the eye to correct refractive errors without removing the natural lens (also known as "phakos", hence the term). Intraocular lenses that are implanted into eyes after the eye's natural lens has been removed during cataract surgery are known as pseudophakic.

  7. Manual small incision cataract surgery - Wikipedia

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

    Complications after cataract surgery are relatively uncommon. Posterior vitreous detachment (PVD) may occur but does not directly threaten vision. [23] 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.
