  2. Cyanopsia - Wikipedia

    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.

    What to expect after cataract surgery “Many patients notice significantly clearer vision within 24–48 hours, although full recovery can take a few weeks,” says Dello Russo. Some may have ...

  4. Intraocular lens power calculation - Wikipedia

    en.wikipedia.org/wiki/Intraocular_lens_power...

    Cataract extraction following refractive surgery poses special problems for the patient and the surgeon because the corneal change as a result of refractive surgery complicates accurate keratometry, a key element of lens implant power calculation. After laser refractive surgery for myopia, this could result in overestimation of corneal power ...

    en.wikipedia.org/wiki/Myopia

    Youth onset myopia occurs in early childhood or teenage, and the ocular power can keep varying until the age of 21, before which any form of corrective surgery is usually not recommended by ophthalmic specialists around the world. [71] School myopia appears during childhood, particularly the school age years. [94]

  6. Clear lens extraction - Wikipedia

    en.wikipedia.org/wiki/Clear_lens_extraction

    In addition to the common complications of cataract surgery, clear lens extraction may also cause premature posterior vitreous detachment and retinal detachment, [2] particularly in patients with high Myopia. However, modern surgical techniques and advanced lens technology have significantly reduced the likelihood of this and other complications.

  7. Phakic intraocular lens - Wikipedia

    en.wikipedia.org/wiki/Phakic_intraocular_lens

    Intraocular lenses that are implanted into eyes after the eye's natural lens has been removed during cataract surgery are known as pseudophakic. Phakic intraocular lenses are indicated for patients with high refractive errors when the usual laser options for surgical correction (LASIK and PRK) are contraindicated.

  8. Refractive error - Wikipedia

    en.wikipedia.org/wiki/Refractive_error

    Other surgical treatments for severe myopia include insertion of implants after clear lens extraction (refractive lens exchange). Full thickness corneal graft may be a final option for patients with advanced kerataconus although currently there is interest in new techniques that involve collagen crosslinking.

    Before surgery (natural crystalline lens, left). After surgery (implanted PCIOL, right). An anterior chamber IOL (ACIOL) Posterior chamber IOL (PCIOL). This is by far the most common type of implanted lens after cataract surgery, as this is the natural and optimum position for a lens. [citation needed] Anterior chamber IOL (ACIOL). A less ...
