  2. Cyanopsia - Wikipedia

    en.wikipedia.org/wiki/Cyanopsia

    The primary causes include post-cataract surgery, certain medications, and, less commonly, neurological or ophthalmological conditions. Post-cataract surgery is a common cause, as replacing the natural lens with a synthetic one increases exposure to blue light, leading to temporary blue-tinted vision. This effect usually resolves as the eye adapts.

  3. 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).

  4. 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.

  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. Cataract surgery - Wikipedia

    en.wikipedia.org/wiki/Cataract_surgery

    Removal of opacified lens from eye to restore vision. Types: Phacoemulsification, manual small incision cataract surgery, extracapsular cataract extraction, intracapsular cataract extraction: Frequency: Hundreds to thousands per million population per year. Outcomes: Restoration of useful vision or significant improvement in most cases: ICD-9 ...

  7. Floater - Wikipedia

    en.wikipedia.org/wiki/Floater

    They are also common after cataract or clear lens extraction operations or after trauma. [citation needed] Floaters are able to catch and refract light in ways that somewhat blur vision temporarily until the floater moves to a different area.

  8. Phacoemulsification - Wikipedia

    en.wikipedia.org/wiki/Phacoemulsification

    Capsular polishing is the removal of lens epithelial cells remaining in the capsule after cataract removal. Capsule opacification can occur when these cells divide and form fibers. The capsular bag can be polished using metallic scrapers, silicone scrapers, Rentsch capsule curettes, an irrigation/aspiration tip, or the ultrasound irrigation ...

  9. Refractive error - Wikipedia

    en.wikipedia.org/wiki/Refractive_error

    Usually resolved after the removal of the lenses. Discomfort upon lens removal may be seen. Neovascularization New blood vessels may form in the iris region and the limbus. This may impair vision. Infections Various viral, bacterial, and fungal infection may be seen in the eye post-contact-lens wear, if proper lens hygiene is not maintained.
