  2. Refractive surgery - Wikipedia

    en.wikipedia.org/wiki/Refractive_surgery

    Refractive surgery. Refractive surgery is an optional eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses. This can include various methods of surgical remodeling of the cornea ( keratomileusis ), lens implantation or lens replacement.

  3. LASIK - Wikipedia

    en.wikipedia.org/wiki/LASIK

    ICD-9-CM. 11.71. MeSH. D020731. MedlinePlus. 007018. [ edit on Wikidata] LASIK or Lasik ( laser -assisted in situ keratomileusis ), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism. [1] LASIK surgery is performed by an ophthalmologist ...

  4. Radial keratotomy - Wikipedia

    en.wikipedia.org/wiki/Radial_keratotomy

    Radial keratotomy ( RK) is a refractive surgical procedure to correct myopia (nearsightedness). It was developed in 1974 by Svyatoslav Fyodorov, a Russian ophthalmologist. It has been largely supplanted by newer, more accurate operations, such as photorefractive keratectomy, LASIK, Epi-LASIK and the phakic intraocular lens.

  5. Photorefractive keratectomy - Wikipedia

    en.wikipedia.org/wiki/Photorefractive_keratectomy

    Photorefractive keratectomy ( PRK) and laser-assisted sub-epithelial keratectomy (or laser epithelial keratomileusis [1]) ( LASEK) are laser eye surgery procedures intended to correct a person's vision, reducing dependency on glasses or contact lenses. LASEK and PRK permanently change the shape of the anterior central cornea using an excimer ...

  6. Laser thermal keratoplasty - Wikipedia

    en.wikipedia.org/wiki/Laser_thermal_keratoplasty

    Procedure. The procedure employs a holmium laser to place a ring of concentric laser burns on the cornea between 6 mm and 7 mm in diameter. These burns cause a ring of constriction on the peripheral cornea causing the cornea to steepen making the eye focus better at near. This procedure may regress somewhat over time.

  7. Small incision lenticule extraction - Wikipedia

    en.wikipedia.org/wiki/Small_incision_lenticule...

    ReLEx Small incision lenticule extraction ( SMILE ), second generation of ReLEx Femtosecond lenticule extraction ( FLEx ), is a form of laser based refractive eye surgery developed by Carl Zeiss Meditec used to correct myopia, and cure astigmatism. Although similar to LASIK laser surgery, the intrastromal procedure uses a single femtosecond ...

  8. Clear lens extraction - Wikipedia

    en.wikipedia.org/wiki/Clear_lens_extraction

    Clear lens extraction, also known as refractive lensectomy, custom lens replacement or refractive lens exchange is a surgical procedure in which clear lens of the human eye is removed. Unlike cataract surgery , where cloudy lens is removed to treat cataract , clear lens extraction is done to surgically correct refractive errors such as high ...

  9. Intraocular lens - Wikipedia

    en.wikipedia.org/wiki/Intraocular_lens

    Intraocular lens. An Intraocular lens ( IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as short sightedness and long sightedness; a form of refractive surgery. If the natural lens is left in the eye, the IOL is known as phakic, otherwise it is a pseudophakic lens (or ...
