  2. Laser blended vision - Wikipedia

    en.wikipedia.org/wiki/Laser_blended_vision

    Laser blended vision is a laser eye treatment which is used to treat presbyopia (ageing eyes; [1] progressive loss of the ability to focus on nearby objects) or other age-related eye conditions. [1] It can be used to help people that simply need reading glasses, and also those who have started to need bifocal or varifocal spectacle correction ...

  3. Refractive surgery - Wikipedia

    en.wikipedia.org/wiki/Refractive_surgery

    myopia hyperopia astigmatism presbyopia. [ edit on Wikidata] Refractive surgery is 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.

  4. 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 ...

  5. Presbyopia - Wikipedia

    en.wikipedia.org/wiki/Presbyopia

    Solutions for presbyopia have advanced significantly in recent years due to widened availability of optometry care and over-the-counter vision correction options. Corrective lenses. Corrective lenses provide vision correction over a range as high as +4.0 diopters. People with presbyopia require a convex lens for reading glasses; specialized ...

  6. Progressive lens - Wikipedia

    en.wikipedia.org/wiki/Progressive_lens

    Progressive lenses are corrective lenses used in eyeglasses to correct presbyopia and other disorders of accommodation. They are characterised by a gradient of increasing lens power, added to the wearer's correction for the other refractive errors. The gradient starts at the wearer's distance prescription at the top of the lens and reaches a ...

  7. Clear lens extraction - Wikipedia

    en.wikipedia.org/wiki/Clear_lens_extraction

    Clear lens extraction (CLE), also known as refractive lensectomy, custom lens replacement (CLR) or refractive lens exchange (RLE) 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 ...

  8. LASIK - Wikipedia

    en.wikipedia.org/wiki/LASIK

    LASIK. 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 an actual cure for astigmatism, since it is in the cornea. [1] LASIK surgery is performed by an ophthalmologist who uses a laser or ...

  9. Corrective lens - Wikipedia

    en.wikipedia.org/wiki/Corrective_lens

    Corrective lens. A corrective lens is a transmissive optical device that is worn on the eye to improve visual perception. The most common use is to treat refractive errors: myopia, hypermetropia, astigmatism, and presbyopia. Glasses or "spectacles" are worn on the face a short distance in front of the eye.
